Dexcom General FAQs

You should order Dexcom G6. As soon as your connected pump integrates with Dexcom G7, you will be able to switch to Dexcom G7.

If you have irritated or sensitive skin please work with your healthcare professional (HCP).
 
This is a summary of two clinical articles published by clinicians independent from Dexcom based on their knowledge and experience.*† Dexcom has not tested these approaches nor do we endorse these specific approaches. For detailed step-by-step instructions on how to use the Dexcom G6 Continuous Glucose Monitoring (CGM) System, please refer to the user guide.
 
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
  • Create an empty oval on the skin with the barrier film and insert sensor on clean skin in center of oval
  • Let barrier film dry completely before placing sensor1,4
  • May apply 1 layer or a second after first layer has drieda

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

The Dexcom G7 sensor is factory calibrated. The 4-digit pairing code found on the G7 Wearable box and Applicator connects your G7 sensor to your smart device or receiver through bluetooth.
 
The Dexcom G6 sensor has two modes:
  • Factory calibration: Enter the 4-digit sensor code found on the G6 sensor you are applying. This provides the highest level of accuracy without the need to enter BG readings.
  • Manual calibration: Don’t enter the 4-digit sensor code. You’ll be prompted to enter BG meter values after the 2-hour warm up, then every 12 hours of the first sensor day and then once a day for the remaining nine days of the sensor session.

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.

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.

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.
