Do you have irritation at the sensor site or sensitive skin? These considerations, skin barriers, and professional tips may help. Remember what works best for one person may not work best for everyone. You may need to try several different products or methods for you and your HCP to figure out what works best.
 
General consideration*
  • Clean skin with oil-free, antimicrobial soap and dry thoroughly1,2
  • Gentle exfoliation recommended for oily skin2
  • Trim hair with dry razor if needed3
  • Do not use any lotion or oil containing moisturizer where you insert the sensor
  • Do not insert sensor immediately after a shower/bath or in a steamy bathroom—minimize humidity with hairdryer or application in a dry environment2
  • Solid or spray antiperspirant (unscented) may help with skin prone to sweating. Create an empty oval on the skin with the antiperspirant, wait 10–15 min. Insert sensor on clean skin in center of oval.1,2
 
Barrier Films*
  • Barrier films may help prevent mild skin irritation from adhesives4

Do you find it painful removing the sensor adhesive? Is there a sticky residue left behind on your skin? These techniques and products may help. Remember that what works best for one person may not work best for everyone. You may need to try several different products or methods to figure out what works best for you.
 
General Removal Techniques
 
Loosen edge of adhesive with fingernail and use products listed below, if necessary.1,2
 
While removing tapes, use fingers of opposite hand to push skin down and away from adhesive. Continue to move fingers on skin toward adhesive as it is removed.2
 
‘‘Fold back’’ technique: Remove adhesive slowly, at low angle, folding back on itself.2
 
‘‘Stretch and relax’’ technique: Films that stretch (e.g., IV3000 or Tegaderm) may be stretched horizontally away from the center (opposite of the fold back technique) while walking fingers under the dressing to continue stretching it.2
 
Use adhesive removal wipes to rub the skin under the tape toward the adhesive as it is removed. This helps loosen adhesive from skin and may help reduce pain with removal.1

Continuous Glucose Monitoring (CGM) systems track glucose levels throughout the day. When used, a tiny sensor wire is inserted just underneath a person’s skin using an automatic applicator. An adhesive patch holds the CGM sensor housing in place, so the sensor can measure glucose readings in interstitial fluid throughout the day and night. A small, reusable transmitter connects to the sensor wire and sends real-time readings wirelessly to a receiver, so that the user can view glucose information. Some systems also allow compatible smart devices to work with the CGM system app as display devices. Then, the receiver or compatible smart device* is able to display real-time glucose levels and historical trends. The CGM receiver and/or compatible smart device can also be set to send custom alerts to the user when certain glucose thresholds are reached.

The A1C test, also known as a glycohemoglobin or hemoglobin (Hb) A1C test, tells you how well you are managing your diabetes by measuring your average blood glucose (sugar) control for the few months prior to the blood test. Normal A1C is between 4% and 6% for a person who does not have diabetes. Your doctor can provide you with your ideal A1C target. A higher A1C increases the risk of complications, including heart attacks, strokes, neuropathy and more, so keeping your blood glucose and A1C in your target range helps lower your risk of complications.

Type 1 diabetes (T1D) is an autoimmune disease that occurs when the body’s own immune system mistakenly destroys insulin-producing cells in the pancreas. Without insulin, cells throughout the body cannot take up energy from glucose, which leads to health complications such as high blood sugar (hyperglycemia), low blood sugar (hypoglycemia), and long-term damage to nerves, vision, and vital organs.
 
Although T1D typically appears during childhood or adolescence, anyone can be at risk. According to the American Diabetes Association, more than 1.25 million Americans are living with T1D and 40,000 will be newly diagnosed each year.
 
Unfortunately, there is currently no cure or methods of prevention for type 1 diabetes.

Although type 2 diabetes is not totally preventable, making healthy lifestyle decisions like dietary changes, increased exercise, and weight loss can help lower your chances of developing it. Those choices can also help prevent further health complications in people with type 2 diabetes and can also help slow or stop the progress of prediabetes. Here are some tips for lifestyle changes:
 
  • Eat healthy foods like fruit, vegetables, and whole grains. These are lower in fat and calories, and higher in fiber than other foods.
  • Aim for a minimum of 30 minutes of exercise every day, with activities like fast walking, bicycling, or swimming laps.
  • Lose extra body weight (7% loss) if overweight to help decrease your risk of diabetes. This can also increase your energy level, improve your self-esteem, and keep your heart heathy.

Researchers are still investigating what causes the onset of type 1 diabetes (T1D). While genetics and family history contribute to your predisposition to developing T1D, an external environmental trigger is also needed to initiate the disease.
 
There are 20-40 gene markers linked to T1D. In most cases, people with diabetes inherit these genetic risk factors from both parents. However, genes aren’t the only cause of T1D. Consider identical twins with identical genes—the American Diabetes Association reports that when one twin has T1D, the other will only contract it up to 50% of the time.
 
Cold weather and lack of sunshine may be a contributing factor to T1D. Cases of T1D tend to arise most often in autumn and winter. Furthermore, the incidence of T1D tends to increase in people who live farther away from the equator.
 
Early diet may also be related. Fewer cases of T1D arise in children who were breastfed as babies and waited until later years to eat solid foods.
 
Some viruses may activate T1D in someone who is susceptible. A virus that has only mild effects on most people may trigger type 1 diabetes in others.

A fasting blood sugar (FBS) level is the result of a blood sample taken after a patient fasts for at least eight hours. A normal fasting blood sugar level for someone without diabetes is less than 100 mg/dL, or HbA1C below 5.7%.
 
Prediabetes is a fasting blood sugar level from 100 to 125 mg/dL, or HbA1C of 5.7%-6.4%. Diabetes is a fasting blood sugar level of 126 mg/dL and above, or HbA1C of 6.5% or higher.

Signs and symptoms of type 1 and type 2 diabetes can include increased thirst and urination, increased appetite, loss of weight, fatigue, change in vision, frequent infection, and patches of darkened skin.
 
Type 2 diabetes occurs when a person has blood glucose (sugar) levels that are higher than normal and their body does not use insulin properly. Causes include genetics and environment and can also include being overweight, but not all patients with type 2 diabetes are overweight.

According to the American Diabetes Association (ADA) guidelines, patients with diabetes should strive to achieve fasting blood glucose levels below 131 mg/dL, and levels following meals below 180 mg/dL. Ideally, patients with diabetes can bring their blood glucose levels as close to normal as possible with lifestyle changes and medication. ADA guidelines recommend HbA1C levels below 7%, or an average blood glucose level below 154 mg/dL.

Hypoglycemia is low blood sugar (glucose). The National Institute of Health suggests this is a level of 70 milligrams per deciliter (mg/dL) or fewer, but ranges of when hypoglycemia symptoms occur vary with every individual. Hypoglycemia can bring on symptoms of shakiness, nervousness, sweating, and hunger. In more severe episodes, an individual may appear intoxicated–with slurred or incoherent speech, impaired motor function, and/or forgetfulness. If left untreated, hypoglycemia can induce a coma.
 
Hypoglycemic episodes can occur when people with diabetes take too much insulin without food, when they exert too much physical activity, or when they drink alcohol. If a person has had diabetes for a long time, they can also develop hypoglycemic unawareness, or the inability to sense low blood sugar levels. Regularly monitoring blood glucose levels, taking insulin doses according to physician instructions, and not skipping meals can help prevent hypoglycemic episodes.

Symptoms related to type 1 diabetes (T1D) build over time or come on suddenly, sometimes within just a few weeks when the disease reaches a critical point. Some signs can include:
 
  • Frequent urination
  • Increased thirst
  • Increased hunger/appetite
  • Dry mouth
  • Itchy or dry skin
  • Unexplained weight loss
  • Yeast infections
  • Irritability and other mood changes
  • Extreme fatigue and weakness
  • Vision changes or blurred vision
 
T1D is a condition in which the pancreas is unable to produce insulin – the hormone that enables your cells to extract energy from the food you eat. Without insulin to properly process sugars from food, excess glucose can accumulate in your blood. Your kidneys may prompt frequent urination to clear the excess glucose. More water is then needed to then stave off dehydration, so excessive thirst, dry mouth and dry skin can occur.
 
Hunger pangs can be a result of your body craving energy. Since cells are unable to properly take in energy in the form of glucose, your body calls for more food to compensate. Even though you may be eating more as a person with type 1 diabetes, you may still lose weight because your body begins to burn fat and muscle to find the energy it needs to function. Since your cells are deprived of energy, you may feel tired and weak.
 
High levels of glucose can cause the lens of your eye to change shape, creating blurry vision. Over the course of time, it can also damage blood vessels on the retina, which leads to the appearance of floaters or even total vision loss.
 
Excess glucose in the blood also affects blood flow to the cells and tissues, especially to the extremities. This can create complications like slow-healing wounds, infections, and nerve damage.
 
Talk to your doctor about blood tests to confirm if you have diabetes.

Diabetes mellitus is a group of diseases that are characterized by abnormally high blood glucose levels, resulting from defects in insulin secretion, insulin action, or both. Mechanistically, type 1 diabetes (T1D) results from immune-mediated, pancreatic β-cell destruction and type 2 diabetes (T2D) is generally multifactorial, resulting from increasing insulin resistance, diminishing insulin production (relative or absolute), and impairments in glucose metabolism. While type 2 diabetes is strongly correlated with obesity, not all patients with type 2 diabetes are overweight.
 
Signs and symptoms of type 1 and type 2 diabetes can include increased thirst and urination, increased appetite, loss of weight, fatigue, change in vision, frequent infection, and patches of darkened skin.

A continuous glucose monitoring (CGM) system offers individuals with type 1 or type 2 diabetes around-the-clock glucose readings with fewer fingersticks–or, depending on the CGM product you choose, none at all.*,† This level of timely feedback from glucose monitors can help users make more informed treatment decisions that may help reduce their A1C levels.1
 
Advantages of Continuous Glucose Monitors
 
Whether you treat your diabetes with multiple daily injections or an insulin pump, you can expect wide-ranging health and convenience benefits from using a CGM device. The benefits of using the Dexcom CGM system include the following:
 

More insight than using a meter alone

  • Unlike a single reading from a blood glucose meter, a CGM provides real-time, dynamic information about the speed and direction (trending higher or lower) of your glucose levels.

 

Improved glycemic control

  • Having continuous feedback on diet, exercise, and insulin requirements from a CGM can help you make more informed treatment decisions. This awareness can lead to tighter glycemic control than using a blood glucose meter alone.2

 

Fast, proactive response

  • The Dexcom CGM systems take glucose readings every 5 minutes and allows you to set customizable thresholds with alerts when your readings are out of target range. This means you could know that you are out of range before you begin to feel symptoms, and you can proactively respond.

 

Fewer fingersticks

  • CGM devices use a tiny sensor to measure glucose levels just beneath the skin. The sensor connects to a transmitter, which wirelessly transmits readings to a receiver or a compatible smart device.‡ At any time, you can see your glucose reading with just a glance.

 

Fewer worries

  • Hear from real Dexcom users about the feelings of freedom and control they have using continuous glucose monitoring systems.
 
1 Beck RW, Riddlesworth T, Ruedy K, et al. Effect of Continuous Glucose Monitoring on Glycemic Control in Adults With Type 1 Diabetes Using Insulin Injections: The DIAMOND Randomized Clinical Trial. JAMA. 2017;317(4):371-378. doi:10.1001/jama.2016.19975.

*Fingersticks required when symptoms or expectations do not match CGM readings.
†Available with the Dexcom G6 CGM System.
‡To view a list of compatible smart devices, visit dexcom.com/compatibility
Dexcom CGM systems provide much more information for users than traditional Self-Monitoring of Blood Glucose (SMBG) does. For Dexcom G6 users, the expected level of accuracy is based on comparisons to fingerstick results–which require careful consideration of timing and technique consistency when drawing blooding glucose values.
 
For a more detailed explanation, please review this guide.
The most common symptoms of type 2 diabetes (T2D) are:
 
  • Increased thirst
  • Frequent urination
  • Increased hunger/appetite
  • Unexplained weight loss
  • Fatigue, or a feeling of being run-down and tired
  • Rapid breathing
  • Blurred vision
  • Dry, itchy skin
  • A headache
  • Tingling or burning pain in the feet, legs, hands or other parts of the body
  • High blood pressure
  • Mood swings
  • Irritability, depression
  • Frequent or recurring infections, such as urinary tract infections, yeast infections and skin infections
  • Slow healing of cuts and bruises
 
Symptoms of T2D are very similar to symptoms of type 1 diabetes (T1D). However, T2D symptoms often come on more gradually; not everyone with T2D will display signs of having the disease. Blood tests are needed to confirm diabetes.

Go to Profile > Alerts to customize each alert. The Low Alert screen below shows some settings you can change:
 
App: Level, Sound/Vibrate, and Snooze
 
Receiver: Level and Snooze
 
 
 
When adjusting the Level setting, think about what sensor reading makes you respond. Set your alert level at that number.
 
For example, if you don’t respond until your sensor reading is 65 mg/dL but your Low Alert is at 80 mg/dL, you’re getting alerts you don’t use. Set your Low Alert level to 65 mg/dL so you only get it when it matters to you.

How does the Dexcom G7 Apple Widget work?
 
The Dexcom G7 Apple widget lets you see your glucose numbers on your lock screen or home screen without opening the app.
 
For the widget to work, your G7 app must still be running in the background when you don’t have the app displayed.
 
 
*Compatible smart devices sold separately. To view a list of compatible smart devices, visit dexcom.com/compatibility
 
Why is the Dexcom G7 Apple Widget displaying “—” and not my glucose number?
 
The widget changes for different situations, such as these:
 
“ —”: Displays where there’s no sensor reading available. The operating system limits the number of times a widget can be updated each day. When the widget hasn’t updated as expected, it will show ”—” instead of a sensor reading and there will be a gap in the trend graph.
 
No Alerts banner and “—”: Displays when there’s an alert that prevents you from seeing a sensor reading, such as Signal Loss. There will be a gap in the trend graph.
 
To open the G7 app, just tap the widget. This will direct you right to the Dexcom G7 App to get your glucose reading when the widget is showing “—“.

Yes, Dexcom G7 works with Dexcom Clarity. Users who used Dexcom Clarity with Dexcom G6 do not need to register again. The G7 app also conveniently integrates a Clarity data summary (called the Clarity card) into the home screen of the G7 app for quick and easy insights. Learn more about Dexcom Clarity here.

When you get an alert, your first priority is to resolve it by making a treatment decision or fixing a system issue.
 
Afterwards, acknowledge the alert on your display device by tapping OK. Until you acknowledge the alert, it will sound every 5 minutes. You can also acknowledge an alert from your Lock screen by following these instructions:

iPhone

Option 1: From the Lock screen, touch and hold the notification until OK appears. Tap OK to acknowledge the alert.
Option 2: Tap the Lock screen notification to open the app. From the app, tap OK on the alert to acknowledge it.

Android

Option 1: If your notification has an OK button, tap OK to acknowledge the alert.
Option 2: If your notification doesn’t have an OK button, pull down on the notification and tap OK to acknowledge the alert.
Option 3: Tap the notification (not the OK button) to open the app. Then tap OK to acknowledge the alert.

Dexcom G7 sensors may be inserted on the back of the upper arm (indicated for users ages 2 years and older) or the upper buttocks (ages 2-6 years old). Our research shows that back of the upper arm wear results in optimal performance*. Sensor placement is important, and you should change your insertion site with each sensor. Using the same site too often might not allow the skin to heal, causing scarring or skin irritation. Be sure to use the overpatch included with your G7 sensor; this will help ensure your sensor will remain in place for the duration of the wear session.

 

See Our Dexcom G7 Videos

 

Choose a site:
  • At least 3 inches (8 centimeters) from any insulin pump infusion set or injection site
  • Away from waistbands, scarring, tattoos, irritation, and bones
  • Unlikely to be bumped, pushed, or laid on while sleeping
 
Follow the Dexcom G7 product instructions. If you have any questions regarding sensor insertion, placement, or otherwise, please refer to the Dexcom G7 product instructions for additional information.

 

Applying your sensor

 

Applying the overpatch

 

The G7 app conveniently integrates a Clarity data summary (called the Clarity card) into the home screen of the G7 app for quick and easy insights. In the clarity card you will find:
 
  • Your average glucose for the past 3, 7, 14, 30, or 90 days
  • Your Glucose Management Indicator or GMI 
  • Your Time in Range
 
 
 
*Healthcare providers can register for Dexcom Clarity at clarity.dexcom.com/professional/registration. †An internet connection is required for users to send their glucose data to Dexcom Clarity via a compatible smart device: https://www.dexcom.com/compatibility. Healthcare providers will only be able to view a user’s glucose data if the user elects to share it with them through Dexcom Clarity.

Dexcom Share is a feature within the Dexcom G7 app that allows for remote monitoring. One person (the Sharer) may share their CGM data with up to 10 designated individuals (the Followers).

 

To set up the Share feature in the Dexcom G7 app, go to Connections > Share and follow the onscreen instructions. Always make treatment decisions using the primary Dexcom G7 app, not the Dexcom Follow app.

The Dexcom G7 has a new sensor patch that contains medical-grade, pressure-sensitive, acrylic-based adhesive, like the previous G6 patch. The only difference in the adhesive is a slight change in the formulation. Both adhesive formulations passed irritation testing, allow for 10-day wear, and contain no latex.
 
If you continue to experience skin irritation, the following link provides additional directions and options that can be reviewed with your healthcare provider to find the best solution for you: https://www.dexcom.com/en-us/faqs/sensitive-skin. General techniques to remove the adhesive patch as well as residue from a previous patch can be found at www.dexcom.com/faqs/removal-techniques. We would also like to follow up with you. If you would like a member of our team to reach out, please submit a request through our Self-Service Patient Support Portal located at: https://www.dexcom.com/priority-support.

The Dexcom G7 sensor is indicated to be worn for up to 10 days, with a 12-hour grace period at the end.

Dexcom G7 has new alert sounds and sound options.
 
The new Quiet Mode allows users to override phone settings:
 
Quiet Mode (Vibrate): When this setting is enabled, all Dexcom G7 CGM System alerts will vibrate only.
  • Quiet Mode Exceptions: Urgent Low Soon and technical alerts will still escalate to sound if not acknowledged.
 
Vibrate: All alerts vibrate but won’t sound. You can set vibrate mode for up to 6 hours or indefinitely.
  • Vibrate Exceptions: Your smartphone vibrate setting must be on for the alerts to vibrate. For more information, go to:
    • For iPhone: Settings > G7 iPhone Safety and tap Complete guide to Dexcom iPhone Settings
    • For Android: Settings > G7 Android Safety and tap Complete guide to Dexcom Android Settings
 
In the app, Urgent Low and the following alerts act differently; if you don’t acknowledge them, they will add sound: App Bluetooth is Off, App is Closed, App Location is Off, App Stopped: Phone Storage Full, App Stopped Working, Phone Bluetooth is Off, Phone Location is Off, Replace Sensor Now, and Sensor Failed.
 
Quiet Mode (Silence All): This setting can be enabled for up to 6 hours, allowing total silence when it is needed. When this setting is enabled, all Dexcom G7 alerts will be silent, and the user will not hear sounds or feel vibrations related to any alerts. However, visual alerts will still be displayed on the user’s compatible display device. Users should check their display device frequently to avoid missing a low or high event. A banner with the stop time shows at the top of your screen when you use these modes.
 
The Dexcom G7 Alert Profile replaces the Alert Schedule from Dexcom G6. The Alert Profile allows users to customize a second group of alerts, which can be used in two ways:
  • You can switch between them manually
  • You can set up a schedule to switch between alerts automatically; for example, to set different alert schedules for daytime and nighttime.
 
In addition, you can now customize a Delay 1st Alert setting for your High Alert. Turn it on to delay your first alert until your sensor reading is at or past the alert setting for a while. You choose how long—for example, if you set Delay 1st Alert to 20 minutes for your High Alert, your glucose must be at or above your high alert level for 20 minutes before you get the alert.
You have the option to use only the Dexcom G7 app on a compatible smart device, * only the receiver, or both at the same time.
 
*Compatible smart devices sold separately. To view a list of compatible smart devices, visit dexcom.com/compatibility
 
¶ Medicare coverage requires use of receiver

Bothered by High Alerts after you eat, even though you took insulin? Talk to your healthcare provider about using the Delay 1st High Alert feature in Profile > Alerts > High. Use it to avoid getting an alert until your glucose has been high for a few hours, or long enough for the insulin to have worked.

 

No. Dexcom G6 sensors, transmitters, and receivers are not compatible with the Dexcom G7 CGM app, sensors, nor receiver. If you would like to use a compatible smart device* with the Dexcom G7 sensor, you will need to download the new Dexcom G7 app. The Dexcom G7 CGM system will work with existing versions of the Clarity and Follow apps.
 
 
 
*Compatible smart devices sold separately. To view a list of compatible smart devices, visit dexcom.com/compatibility
The Signal Loss Alert occurs when your display device* temporarily stops getting glucose readings from your Dexcom G7 sensor. Your last sensor reading will show on your display device for 10.5 minutes, if a new reading does not come in after that time, your display goes to —, indicating that there has not been a reading. After that, your display screen will show the Signal Loss error message.
 
Your display device may be too far from your sensor or there may be something, such as a wall or water, interfering with your sensor and your display device. Smartphone settings, like certain battery optimization options (see Battery Optimization settings in the recommended iPhone or Android phone settings) can also cause Signal Loss. The Dexcom G7 sensor only sends glucose readings by Bluetooth for a short period of time once every 5 minutes, so once you correct the issue, it can still take a while to see a new glucose value.

Insulin and food both take time to work. Avoid getting repeated alerts while you wait. To do so, go into the alert settings and turn off the Snooze feature.

The trend arrow tells you the speed and direction of your glucose level. There are times that the Dexcom G7 sensor may be temporarily unable to accurately measure this and will not show trend arrow on your display device. When this happens, make sure to use your blood glucose meter to make diabetes treatment decisions.

You can see the events you’ve tracked on your display device. On the receiver, navigate to the Event Log, and you’ll see a list of the last 15 events you logged.

 

 

After you upload your receiver data to the Dexcom Clarity app or website, your events will be in your Clarity reports. Go to the Dexcom Clarity appendix for more information.

You can see the events you’ve tracked on your display device.
In the app, navigate to the History tab, and you’ll see a list of the events logged in the last 3 days.
 
 
Events you have logged in your G7 app will be available in your Dexcom Clarity reports when your data is updated from your Dexcom G7 device.
Press the applicator more firmly against your skin before pushing the button. You can’t press the applicator button until you push the applicator so firmly against your skin that the clear safety guard pushes in. Then the button activates, and you can press it to insert the sensor.

The latest Apple iPhones and many of the popular Android smart phones are compatible with both Dexcom G6 and G7; however, there are some differences between the systems. Some of the newest Android phones are still being tested and will be added as they pass our testing. Some of the older Android phones will not be added for Dexcom G7 as we prioritize adding new phones as quickly as possible.
 
Please visit https://www.dexcom.com/compatibility for the latest list of compatible devices.
 
For those whose smart device is not currently compatible with Dexcom G7, we encourage users to take advantage of the newly redesigned G7 receiver that is smaller, with a more vibrant, easier-to-read display. 
The Power Off option powers down the receiver and acts as an on/off button, temporarily turning off all communication between your Dexcom G7 sensor and receiver during a sensor session. You won’t get sensor glucose readings during this time, and using the Power Off option won’t extend the life of your sensor. If you use the Power Off option, you can turn your receiver back on by holding down the right button with a circle on it (the Select button) for 3-5 seconds. Give the receiver at least 10 minutes for it to display a reading after it turns back on.
 
The Stop Sensor Session option ends a sensor session. After activating this option, you will not get sensor glucose readings. If you want to continue getting glucose readings, you must insert and pair a new sensor.
We assess whether to keep supporting older Operating Systems (OS) for Dexcom apps on an annual basis. When an OS you’re using is no longer supported for your Dexcom app, we will ask you to update your OS to continue getting app updates.
 
Your current Dexcom app version may continue to work, but you won’t be able to get future app updates until you update your OS to the new required minimum OS. Not all OS updates will be compatible with the Dexcom G7 app right away, if possible, keep your smart devices Automatic Updates turned off to avoid automatically updating to an unsupported Operating System

Children ages 2-6 years old can wear the Dexcom G7 sensor on the upper buttocks. To support the accuracy and effectiveness data submitted for Dexcom G7, we enrolled subjects ages 2-6 years for upper buttocks wear location. The subjects 7 years and older wore only on the arm in this study.

Follow the insertion instructions carefully and be sure to use the sensor overpatch included with your G7 sensor. Here are some tips that may help you keep your sensor on for the entire sensor session.

 

Site preparation

  1. Site: Sensor site should be flat, clean, and completely dry before you insert the sensor. There should be some fat under the skin at the sensor site.
  2. Extra adhesive: Put additional adhesive on the patch before applying the overpatch and let dry. 
  3. Placement: The patch stays on best when it’s not where your skin folds
  4. Avoid hair: Apply the patch to areas without a lot of hair. If needed, shave the site with electric clippers.
  5. Old adhesive: Remove any adhesive residue from previous sensors. Consider using a body oil or adhesive remover for skin (such as Uni-solve, Detachol, or Tac Away).

 

Patch care

  1. Ask a friend, family member, or healthcare provider to help insert your first Dexcom G7 sensor and apply the overpatch.
  2. Look in a mirror while positioning the applicator or applying your overpatch.
  3. The longer you keep it dry and sweat-free in the first 12 hours, the longer it may stick to your skin
  4. When it gets wet, gently pat it dry as soon as you can
  5. If it peels off your skin, trim the peeled parts and put on medical tape.

You must end the Dexcom G7 sensor session or grace period before you start a new sensor. You can end it in one of two ways:
  • Automatically, when the grace period ends (you’ll get an alert letting you know)
  • Manually, before the grace period ends
 
Automatically: End sensor when grace period ends
 
At the end of the grace period, you’ll get the Start New Sensor alert:
 
 
 
Manually: End sensor before grace period ends
 

Yes, Dexcom G7 Continuous Glucose Monitoring (CGM) system is indicated for pediatric patients two years and older with any type of diabetes.

The G7 sensors are indicated for use on back of upper arms because, during testing, users who wore it there had optimal system performance.

The Dexcom G7 sensor can only connect with one smart device at a time. If you get a new smartphone, for example, you need to:
 
  1. Copy the Dexcom G7 pairing code from your old smartphone’s Dexcom G7 app under Connection > Sensor
  2. Go into your old smartphone’s Bluetooth settings
  3. Turn Bluetooth off
  4. Wait at least 15 minutes before connecting your new smartphone to your Dexcom G7 sensor. Once your new smartphone is connected, install the Dexcom G7 app.
  5. After it is installed, go into your new smartphone’s Bluetooth settings
  6. Turn your Bluetooth off and on
  7. Wait 15 minutes
  8. Log into your Dexcom account and go through the app setup wizard

You can share your glucose data with Apple Health, a health and fitness tracking app included on Apple devices. Please note that Apple Health receives your Dexcom G7 information after a three-hour delay, not in real time.
 

To share glucose data with Apple Health:

  1. Tap the Connections tab in the Dexcom G7 app
  2. Tap Apple Health
  3. Tap Activate to share
  4. Tap the Blood Glucose switch on the Health Access screen
  5. Tap Allow

Dexcom recommends that users dispose of used Dexcom G7 applicators following local guidelines for blood-containing components.

No. Dexcom recommends using either Dexcom G6 or Dexcom G7, but not both simultaneously.

Have you ever wondered why your blood glucose (BG) meter and Dexcom G7 Continuous Glucose Monitor (CGM) reading are not the exact same number?
 
One explanation is that a BG meter measures glucose from the blood while Dexcom G7 measures interstitial fluid, so those numbers may be different. And, if your doctor did a lab test at the same time, the lab result may give a third number. The lab result is considered the most accurate number. Even if you wore two CGM sensors at the same time CGM sensor performance may vary slightly.
 
Other reasons there could be a difference between your BG meter and your Dexcom G7 are:
  1. Hand cleanliness: Wash your hands with soap and water (not hand sanitizer) and dry them. Then test. Many inaccurate BG meter values are from hands not being washed thoroughly before testing.
  2. Sensor’s first day: With newly inserted sensors, the differences between your BG meter and the Dexcom G7 reading may be greater. Generally, the numbers get closer over the first 24 hours.
  3. Pressure on Dexcom G7: Sometimes when something is pressing on your sensor, for example, if you’re lying on it, it can affect your Dexcom G7 readings. Relieve the pressure and the numbers should get closer.
  4. Glucose changing quickly: When your glucose is rapidly changing, it can be more difficult to compare your meter and Dexcom G7 because blood glucose changes a little before interstitial fluid glucose. The match should get closer when your glucose stabilizes.
  5. Test strips: Make sure your test strips are stored as directed and not expired. Also, make sure to use enough blood on the test strip.

 

Calibrating vs. Comparing

Calibrating is when you take a fingerstick/finger prick and enter that BG reading into your Dexcom G7.
 
Comparing is when you take a fingerstick/finger prick and do not use it to calibrate, but rather for comparison and awareness. With Dexcom G7, you can choose to log blood glucose instead of calibrating.
 
You can log your BG meter value in the G7 app’s Glucose or History tabs. In the receiver, go to Menu > Event > Blood Glucose.
 
If your sensor readings are always much higher (or always much lower) than your BG meter values for several hours, consider calibrating.
 

Comparing

You can compare your BG meter and Dexcom G7 reading to see how closely the numbers match each other.
 
Use the table to find out how your BG meter compares to your Dexcom G7 reading. Follow these steps:
  1. In the first column, find the BG meter value closest to yours.
  2. In that row, check whether your Dexcom G7 reading fits into the range in the second column.
 
If it fits, treat using the number that best fits your symptoms, whether it’s from your Dexcom G7 or your BG meter. If it doesn’t fit, don’t treat with your Dexcom G7. Use your BG meter value instead.
 
This table provides sensor readings that are within ± 20% of the BG meter value for BG meter values
≥70 mg/dL and within ± 20 mg/dL of the BG meter value for BG meter values <70 mg/dL.
 
iCGM accuracy is established by comparing to a lab analyzer YSI. Use this table as reference only.
 
Calibration
Calibrating your Dexcom G7 is optional. It can make the Dexcom G7 more accurate or less accurate compared to the lab result, but it should bring the Dexcom G7 readings closer to your meter value. When calibrating, make sure to:
 
Clean hands: Wash your hands with soap and water and dry them.
 
Enter within 5 minutes: Enter the calibration within 5 minutes of taking a fingerstick/finger prick.
 

Calibration Tips:

Pressure on sensor: If the sensor reading seems inaccurate because of pressure on the sensor, don’t calibrate. The sensor should recover on its own when the pressure is relieved.
 
Stable glucose: Calibration works best when your glucose is stable. Consider waiting to calibrate if your glucose is changing rapidly.
 
To calibrate your G7 using your BG meter (optional):
 
 
When you calibrate your G7 using your BG meter, remember:
 
Calibrate in one display device: Calibrate in one display device, even if you use both the app and receiver.
 
Meter values: Only calibrate with BG meter values from 40 mg/dL to 400 mg/dL.
 
Calibration Not Used alert: If you get a Calibration Not Used alert, take another fingerstick/finger prick and calibrate again.

Although you can change your target range in the Dexcom Clarity App and website, the G7 Clarity Card display defaults to the following recommended ranges from an international consensus:
 
Target Range: 70-180 mg/dL
Very High: Above 250 mg/dL
Very Low: Below 54 mg/dL
 
The target range default of 70-180 mg/dl may affect the calculations seen within the G7 Clarity Card and may differ from the customizable ranges you can set in the Dexcom Clarity App and website.
If you have entered a calibration, you may see Calibration Not Used in your History tab. This means that your Dexcom G7 sensor was not able to use the calibration you entered, so your glucose readings may not be aligned to your blood glucose (BG) meter.
 
If you see this message, give your sensor some time to adjust; then, try calibrating again in about an hour with a new fingerstick/finger prick. To get an accurate BG meter value, follow these steps:
 
  1. Wash your hands with soap and water
  2. Dry your hands
  3. Take a fingerstick/finger prick

You can turn off most alerts in their settings. The alerts you can’t turn off in their settings – Urgent Low and technical alerts (like Sensor Fail) – can be set to vibrate using Quiet Modes in the app or Alert Sounds on the receiver.

 

 

If using an Apple smart device, you’ll need to enable Critical Alerts during the app onboarding process in order to use the Dexcom G7 app. Critical Alerts should always play a sound and appear on your lock screen when your smartphone notifications are off, muted, or on Do Not Disturb. Critical Alerts include Urgent Low and Sensor Fail.
 
If you turn off your Critical Alerts, you will be blocked from using the Dexcom G7 app until you turn them back on.
 
How to turn Critical Alerts back on:
  1. Go to your smart device’s Settings
  2. Tap Dexcom G7
  3. Tap Notifications
  4. Toggle Critical Alerts to turn them on

Dexcom G6 FAQs

DEXCOM G6 CONTINUOUS GLUCOSE MONITORING SYSTEM (DEXCOM G6) READING AND METER VALUE
 
Whether you’re new to Dexcom or experienced, review product instructions before using the Dexcom G6. Keep using your BG meter to make treatment decisions until you know how Dexcom works for you. Your meter gives you one number, if you test twice (using the same or a different meter) it gives you another number, and your Dexcom G6 gives you a third. What do you do with all those numbers?
 
 
 
The test
 
The test your doctor does is considered a more accurate glucose number than any products you use at home. Both meters and Dexcom G6 are compared to that doctor’s test to measure accuracy in clinical studies. They aren’t compared to each other. Because of this, the Dexcom G6 reading (G6 reading) and meter value are unlikely to be exactly the same number, but they should be close. Compare the meter and your Dexcom G6 to see how closely the numbers match each other: if your G6 reading and meter value are within what we call the 20 rule (also known as the %20/20 rule), they match closely.
 
The rule
 
To use the 20 rule follow these steps using the table below:
 
  1. Look up your meter value in the green middle column.
  2. The left G6 – column shows the low range for a G6 reading that’s a close match.
  3. The right G6 + column shows the high range for a G6 reading that’s a close match.
 
For example, the orange highlighted row shows that if your meter value is 100 mg/dL, your G6 reading is a close match if it’s between 80 and 120 mg/dL.
 
 
Good fingerstick practices
 
When using your meter, make sure:
 
  • Your test strips are stored as directed and not expired.
  • Your hands are clean for the fingerstick. Wash your hands thoroughly with soap and water (not hand gel) and dry them. Then test.
 
There are times when the numbers temporarily don’t match, but are likely to become closer over time. For example:
 
  • Sensor’s first day. With newly inserted sensors, the differences between your meter value and the G6 reading may be greater. Generally, the match gets closer over the first 24 hours.
  • Glucose changing quickly. When your glucose is changing quickly, it’s more difficult to compare numbers. The meter and Dexcom G6 measure glucose from different sources (blood and interstitial fluid), and blood glucose changes a little before interstitial fluid glucose. The match gets closer and easier to compare when your glucose stabilizes.
  • Pressure on sensor. When something is pressing on your sensor it can affect your G6 readings. The match should get closer after the pressure is relieved.
 
To determine what to do, watch your G6 readings over several hours. If the readings are always higher (or always lower) than your meter values and always outside the 20 rule, consider calibrating. Also consider calibrating if your Dexcom G6 and meter numbers don’t match and your expectations or symptoms fit the meter value, not the G6 reading.
 
Calibration
 
Calibrating your Dexcom G6 with your meter is never required. It can make the Dexcom G6 more accurate or less accurate compared to the lab result, but it should bring the G6 readings closer to the meter values.
 
When calibrating, make sure:
 
  • You enter the calibration within 5 minutes of taking a fingerstick.
  • You don’t calibrate during Sensor Error.
 
If you’d like, you can calculate the 20 rule on your own. The Dexcom G6 reading must be within:
 
  • 20% of the meter value when the meter value is 80 mg/dL or higher
  • 20 mg/dL of the meter value when the meter value is under 80 mg/dL
 
*Please note: the information listed here is applicable to Dexcom CGM users within the US only.
You will receive transmitter end of battery life alerts on your display device. You should use the transmitter until you receive the message to pair a new transmitter.

Review the following information to make sure that you continue to receive CGM readings when using a compatible smart device *:
 
  • Keep Bluetooth pairings in your phone to a minimum. (Note) Dexcom G6 transmitters connect, send data, and disconnect every 5 minutes. The pairing in Bluetooth will say “not connected” and is expected.

 

  • The Dexcom G6 app should never be closed. Keep any additional running apps to a minimum in the background. High-intensity apps, like mobile games or video sites, draw large amounts of processing power and may cause signal loss.

 

  • Keep your phone charged. If your phone goes into low power mode, that will turn off Bluetooth and cause connection issues with the Dexcom G6 app and transmitter.

 

  • Your phone settings can prevent the Dexcom G6 app from working.

See Our Dexcom G6 Videos

If you’re already familiar with continuous glucose monitoring (CGM) systems the Dexcom G6 CGM System may or may not notably affect your day-to-day routine. However, you may benefit from the Dexcom G6 features that were designed for greater ease and convenience, such as:
 
  • The Dexcom G6 transmitter, which is slimmer and more discreet than that of previous models.
  • A redesigned auto applicator, which simplifies the sensor insertion process with a push of a button.
  • A sensor that is indicated for up to 10 days of use.
 
Unlike previous generations, the Dexcom G6 also stands out as the first real-time, integrated CGM (iCGM) requiring zero fingersticks* or scanning.
 
Even if you’ve never used a CGM system, you can benefit from the significant advantages that the Dexcom G6 offers compared to other glucose monitoring methods, like fingersticks with blood glucose meters.

Dexcom designed the Dexcom G6 CGM System sensor auto-applicator for easier, more consistent sensor insertions. We recommend viewing the Dexcom G6 Videos for a helpful demonstration of the sensor insertion and transmitter attachment process. The video is available in both English and Spanish.

Dexcom G6 sensors may be inserted on the abdomen (indicated for patients age 2 years and older) or the upper buttocks (ages 2-17 years). Sensor placement is important and you will want to change your insertion site with each sensor. Using the same site too often might not allow the skin to heal, causing scarring or skin irritation.
 
Choose a site:
 
  • At least 3 inches from any insulin pump infusion set or injection site
  • Away from waistbands, scarring, tattoos, irritation, and bones
  • Unlikely to be bumped, pushed, or laid on while sleeping
 
Follow the Dexcom G6 instructions for use. If you don’t, you could experience a severe low or high glucose event. If you have any questions regarding sensor insertion, placement, or otherwise, please refer to the Dexcom G6 User Guide for additional information.
 
Dexcom G6 – Inserting the Sensor and Attaching the Transmitter
 

The Dexcom G6 auto applicator was designed for easier, more consistent sensor insertions. According to a survey of Dexcom G6 users, 84% reported that the initial sensor insertion was painless and 100% reported that the applicator was easy to use.

 

For study details, please reference the Dexcom G6 user guide.

Don’t ignore broken or detached sensor wires. A sensor wire could remain under your skin. If this happens, please contact Dexcom’s 24/7 Technical Support at 1-844-607-8398.
 
If a Dexcom G6 sensor wire breaks off under your skin and you can’t see it, don’t try to remove it. Contact your healthcare provider immediately. You should also seek professional medical help if you experience symptoms of infection or inflammation (such as redness, swelling, or pain at the insertion site).
 
Follow the Dexcom G6 instructions to help avoid this from happening. If you don’t, you could miss a severe low or high glucose event.

Dexcom G6 sensor replacement frequency: A single Dexcom G6 sensor can be worn up to 10 days. For tips on keeping your sensor on for the full 10-day wear, please reference the sensor adhesive tips.

 

To learn more about how to change your Dexcom G6 sensor after 10 days of wear, see our Dexcom G6 videos.

How to end a sensor session early:
 
Go to the main menu of the Dexcom G6 App, scroll to the bottom of the menu, select “Stop Sensor,” and select “Yes”. After ending the session, you will be taken to the home screen, where you will see a “New Sensor” option. Please follow the on-screen steps once you select “New Sensor”. If you need to end your sensor session early, such as for procedures where you can’t wear the sensor, please follow the above steps.
 
How to end a sensor session:
 
On the 10th day of your sensor session, you will receive a notification that your session is about to end. You will receive these notifications 24 hours, 6 hours, 2 hours, and 30 minutes prior to the official end of the sensor session. The session will end on its own to the exact hour and minute that the start sensor option was selected 10 days prior.

How to remove your Dexcom G6 sensor and transmitter:

When you remove your Dexcom G6 sensor, your transmitter will also come off. Remember that your transmitter is reusable; don’t throw it away until its battery has died. One transmitter has a battery life of 90 days, so you can use the same transmitter over a number of sensor sessions. You will receive notifications as the transmitter nears the end of its battery life.
 
Follow these easy steps:
 
person removing sensor from abdomen

STEP 1:

First, grab the edge of the adhesive patch, then peel the adhesive and transmitter up and away from your body like you’re removing a bandage.
 
hands removing transmitter from holder

STEP 2:

Next, to remove the transmitter from the holder, push down the lip of the transmitter holder and break open its wide end.

STEP 4:

Throw away patch, with the holder and sensor attached, following your local guidelines for disposal of blood-contacting components.
 

Start a new Dexcom G6 sensor session

 

After removing the Dexcom G6 sensor from your body and the transmitter from the transmitter holder, you’re ready to start a new sensor session. You won’t have to pair your transmitter to your compatible smart device;* the transmitter will remain paired until the end of its battery life. However, you will need to enter a new sensor code, because the code is specific to each sensor.
No. If you entered the sensor code during setup, there’s no need to calibrate. You can calibrate if you want, but the system doesn’t require it. The Dexcom G6 CGM System stands out as the first real-time, integrated CGM (iCGM) requiring zero fingersticks or calibrations. You must enter the unique Dexcom G6 sensor code that is printed on each sensor’s adhesive label during the startup period for no calibrations to be required.
Exceptions to Consider:
 
If you don’t enter a sensor code, you will be prompted to manually calibrate your CGM using values obtained from a blood glucose meter and fingersticks. You will also be prompted to calibrate twice after sensor warmup before you will begin receiving Dexcom G6 readings. Then, you will be prompted to calibrate 12 hours later and once more at the 24-hour mark (another 12 hours later). For the rest of your 10-day session, you will be prompted to calibrate once every 24 hours.
 
If you receive a calibration notification outside of your scheduled calibrations, the system didn’t accept your most recent calibration or your meter value is very different from your G6 reading. You must calibrate immediately when the G6 notifies you. If you haven’t calibrated when notified, your G6 may not be accurate, so use your glucose meter to make treatment decisions until you calibrate your G6.
 
How Do I Calibrate?
 
Take a fingerstick with your meter, and enter the meter value into your display device. When taking a fingerstick, it’s important to do it correctly. Make sure you thoroughly wash and dry your hands right before. And remember: Always use your finger, never another site.
The transmitter battery is good for 3 months. We recommend that you have your next transmitter in hand within 3 months of starting your previous transmitter.
 
If you haven’t received your final 10-day transmitter battery life warning, you can reuse the transmitter for your next session. Starting at 3 weeks before the end of its battery life, the warnings count down the transmitter battery life until it has only 10 days – one sensor session – left. If the transmitter battery has less than 10 days remaining, you won’t be able to start a new session and will see “Pair New Transmitter” instead.

Yes, Dexcom G6 is compatible with the Dexcom Clarity software. Patients will not need to register again, nor download a new Dexcom Clarity app, if they have an existing account. If you are already sharing your glucose data with your clinic, the clinic will not need to reconnect. For more information on Dexcom Clarity, please visit clarity.dexcom.com.

Dexcom Share is a feature within the Dexcom G6 app that allows you to share your glucose data with up to 10 designated persons (followers). Designated followers who download the Dexcom Follow app will then be able to remotely mo
