Is Dexcom For Type 2 Diabetes


Flash Sensors And Cgm Sensors

A Dexcom Warrior Story â Patti LaBelle on How to Manage Type 2 Diabetes with Dexcom G6

With a flash glucose monitor, sensors should be worn on the arms only. And we recommend that they arent placed over areas with tattoos as this could impact your results. With a CGM, you can wear the sensor on different parts of the body, such as your abdomen.

The sensors dont normally need to be taken off. You can usually wear them in the bath, shower and during sports. But some people do have problems with them falling off. There are adhesives you can buy to keep them in place.

You cannot remove a sensor for a while once it has come off you need to replace it with a new one.

How often you have to change the sensor will depend on the type of model youre using and the manufacturers instructions. Youll usually need to change it at least once every 14 days.


Its quick and painless to put on a sensor. You insert them just under the skin using an applicator.

Are Both Dexcom And Freestyle Libre Covered By Insurance

While this depends on your personal insurance plan, many insurances now cover CGMs for people with diabetes similar to how they cover traditional finger stick meters. Its possible your plan may only cover one brand, so its best to contact your insurance to ask for details.

If you do not have diabetes and are interested in using a CGM, it is unlikely your insurance will cover these devices. This may also be the case if you have prediabetes or gestational diabetes . But there are still some ways to save and avoid paying the full retail price.

Is Dexcom G6 Covered By Insurance

CGM doesnt come cheap. In general, health insurance is more likely to pick up the tab for CGM for someone who has Type 1 diabetes. The good news is that more and more people who have Type 2 diabetes are getting coverage. Youre more likely to get insurance coverage if you have high blood sugar , frequent episodes of low blood sugars, or hypoglycemia unawareness.

In Study Dexcom Finds Cgms Can Benefit Type 2 Patients Too

A new study published today in Annals of Internal Medicine and sponsored by Dexcom shows that a continuous glucose monitor could lower the HbA1c scores of people with Type 2 diabetes, and that acceptance of the technology is high among that group as well.

Right now, continuous glucose monitoring is a technology mostly used by people with Type 1 diabetes, many of whom administer insulin via an automated pump. But people with Type 1 diabetes make up just 5 to 10 percent of people with diabetes in the US, according to the CDC. The others have Type 2 diabetes and often administer insulin via multiple daily injections .

We have been successful in driving innovation and adoption of CGM in the Type 1 diabetes community, but this arm of the DIaMonD study is one of the first to examine how well CGM works for people with Type 2 diabetes on MDI, Kevin Sayer, president and CEO of Dexcom, said in a statement. We are pleased to see a significant A1C reduction in this study, showing that the millions of people globally with Type 2 diabetes on MDI insulin therapy can benefit from CGM use.

On its earnings calls to investors, Sayer has made no secret about Dexcoms aspirations to widen its total addressable market by eventually marketing its CGMs to people with Type 2 diabetes. This study is the first step in clinically validating that approach.

Furthermore, CGM users were adherent to the device and overwhelmingly rated the benefits of the technology as high and the hassles as low.


Dexcom Study Shows Monitor Works For Patients With Type 2 Diabetes

Dexcom wins FDA approval for next generation of glucose monitors for ...

Nancy Crotti | Aug 21, 2017

A new study of Dexcom’s G4 Platinum continuous glucose monitor showed that more than half of the participants experienced a 10% or higher reduction in an important indicator for developing diabetes-related complications.

The 24-week study of blood glucose levels in 158 adults who have Type 2 diabetes and inject multiple doses of insulin daily showed significant reductions in Hemoglobin A1c . Mean HbA1c levels dropped by an absolute percent change of 0.8% in the CGM group and 0.5% in the control group, with 73% of the CGM users experiencing a drop of more than 0.5%, the study found.

A mean HbA1c reduction of 0.3% represents a meaningful improvement. Measuring HbA1c indicates how high a patient’s blood glucose level has been on average over a period of 8-12 weeks.

The DIAMOND randomized trial did not, however, reveal any changes in hypoglycemia, a dangerous and often hidden effect of the disease. The study participants had extremely low baseline rates of hypoglycemia, limiting the CGM’s ability to assess the benefit of measuring it, the company said.


Despite this, Dexcom was crowing over its CGM’s performance among patients with Type 2 diabetes, whose blood sugar is usually better controlled than those with Type 1. The company also pointed out that its study results beat those of Abbott’s Freestyle Libre Flash CGM in a study last year that showed no HbA1c benefit in a similar patient population.

Difference Between A Flash Glucose Monitor And A Cgm

With a CGM your latest sugar levels show up on device or mobile automatically, transmitted by Bluetooth. With a flash glucose monitor, its only when you wave your device over your sensor that you get your blood sugar readings.

Some people prefer to use Flash over CGM. Reasons can include not liking the alarms. But unlike Flash, a CGM can talk to an insulin pump, if you want to use a closed loop system.


Your diabetes healthcare team should be able to support you to make the decision on which device will be best for you.

Which Other Devices Does Dexcom G6 Work With

When the FDA approved the G6 in 2018, the agency created a brand-new category of device that it refers to as iCGM, or Integrated CGM a system designed to connect directly with other compatible devices, such as a smartphone, insulin pump, or other wearable.

Devices that currently work the Dexcom G6 include the latest Omnipod tubeless insulin pump, as well as the tubed Tandem t:slim X2 insulin pump with Basal-IQ and Control-IQ closed loop features. Not sure whether your device is compatible with Dexcom G6? You can check that out here.

Whats exciting is that the future Dexcom G7 model will have even more advanced features, and integration with automated diabetes management systems.

How To Use Technology For Glucose Monitoring

Dexcom G4

These days, there are many different glucose monitoring devices on the market. Some may require a finger prick and blood sample to get a reading. Others are more sophisticated and can be worn directly on the body.

Continuous glucose monitoring devices can provide real-time glucose readings up to every five minutes, throughout the day and night. This can be especially useful for people who experience hypoglycemia at night or who forget to check their levels regularly throughout the day.

CGM devices are worn on the body and send glucose readings to a receiver or smart device and show how your glucose levels fluctuate over the course of a day. Some also show how often you stay within an average range, also called time in range . Some CGM devices have alerts that can notify you if your glucose levels are getting too high or too low. Some devices also allow you to send alerts and share your glucose readings with chosen followers. Shareable features can be used to keep your family, friends, and healthcare team informed of your daily glucose levels.

You can also manually check your glucose levels throughout the day with a blood glucose monitoring device. BGM devices require you to prick your finger with a lancet to get a blood sample for a glucose reading. The downside of BGM devices is they only give you a single reading for that point in time.


No matter which type of device you use, there are some important things to keep in mind when using one:

Metabolic And Safety Outcomes

Change in body weight, blood pressure, or nonHDL cholesterol appeared similar between groups . Between 8 and 14 months, two severe hypoglycemic events occurred in one participant in the continue CGM group and none in discontinue CGM group or the BGM group. Details of these two events are provided in Supplementary Table 12. There were no occurrences of diabetic ketoacidosis.

How Much Does It Cost

Dexcom CGMs are covered by a large array of private insurers in the United States. As of fall 2020, Medicare does cover the Dexcom G6, as well.

Of course, benefits vary by plan, so youll need to check with yours. Just remember that youll need a prescription for the G6 transmitter as well as the box of sensors, so youll have to work with a healthcare professional before purchasing.


Until spring 2021, Dexcom sold their systems and supplies directly via their website. But they now work with distributors like Edgepark for online ordering.

Short answer: The Dexcom G6 is a great tool for any adult or child with any type of diabetes, including those who are pregnant or diagnosed with gestational diabetes, given how important tight glucose management is during pregnancy.

The benefits of CGM use are well-documented:

  • helps avoid severe high or low blood sugars, especially immediately dangerous hypoglycemic events
  • helps guide insulin dosing and safeguard users from suffering mistakes
  • sense of safety and security for those who dont feel dangerous lows coming on
  • increased glucose time in range for better diabetes control
  • lets users see and learn from the direct impact of their food and physical activity on their body

In fact, CGM is so powerful for improving overall health outcomes that its quickly becoming a consumer wellness product.

Theres little doubt that all people with diabetes can benefit, but
