Dexcom G6 sensors have revolutionized diabetes management by providing continuous glucose monitoring (CGM) systems that offer real-time insights into blood sugar levels. However, despite their effectiveness, several misconceptions surround these innovative devices. In this article, we debunk seven common myths associated with Dexcom G6 sensors.

Dexcom G6 Sensors Are Painful

One prevalent misconception is that using Dexcom G6 sensors is a painful experience. Contrary to this belief, the insertion process is quick and relatively painless. The sensor's thin, flexible filament is inserted just beneath the skin's surface, causing minimal discomfort.

Dexcom G6 Sensors Are Inaccurate

Another myth suggests that Dexcom G6 sensors are not accurate in measuring blood glucose levels. However, studies have shown that these sensors provide highly accurate readings, with a mean absolute relative difference (MARD) of around 9% when compared to laboratory measurements.

Dexcom G6 Sensors Are Complicated to Use

Some individuals may be hesitant to adopt Dexcom G6 sensors due to the misconception that they are complex to use. On the contrary, these devices are designed with user-friendliness in mind, featuring simple insertion processes and intuitive smartphone apps for data monitoring.

Dexcom G6 Sensors Are Only for Type 1 Diabetes

While Dexcom G6 sensors are commonly associated with type 1 diabetes management, they are also beneficial for individuals with type 2 diabetes. Continuous glucose monitoring can aid in optimizing blood sugar control and reducing the risk of complications for all diabetes types.

Dexcom G6 Sensors Are Not Covered by Insurance

One of the concerns surrounding Dexcom G6 sensors is their cost and insurance coverage. However, many insurance plans now cover CGM systems like Dexcom G6, recognizing their value in improving diabetes management and reducing long-term healthcare costs.

Dexcom G6 Sensors Cannot Be Worn During Water Activities

Contrary to popular belief, Dexcom G6 sensors are water-resistant and can be worn during various water activities, including swimming and showering. This feature ensures continuous glucose monitoring even in environments where other monitoring methods may be impractical.

Dexcom G6 Sensors Are Expensive

Cost is often cited as a barrier to accessing Dexcom G6 sensor. While the initial investment may seem significant, many users find that the benefits of improved glucose control and reduced hypoglycemia events outweigh the expenses associated with CGM systems.

The Advantages of Dexcom G6 Sensors

Beyond debunking common myths, it's essential to highlight the advantages of Dexcom G6 sensors. These include real-time glucose monitoring, customizable alerts for high and low blood sugar levels, and the ability to share data with caregivers or healthcare providers for better collaborative care.

Real-life Experiences with Dexcom G6 Sensors

Many individuals with diabetes have shared their positive experiences with Dexcom G6 sensors, citing improved quality of life, better glycemic control, and greater peace of mind knowing that they have access to real-time glucose data.


In conclusion, Dexcom G6 sensors are valuable tools for managing diabetes, despite the misconceptions that surround them. By debunking these myths and highlighting their benefits, individuals can make informed decisions about incorporating CGM technology into their diabetes management regimen.
