Common problems with Dexcom G7 falling off

Although the Dexcom G7 sensor comes with remarkable properties. Still, there are certain cons that some users have faced. One of the most common problems faced by people is Dexcom G7 sensor falling off which can lead to Dexcom G7 sensor failure.  Following are some common problems related to this issue. 

Adhesive quality 

In the Dexcom G7 sensor, the adhesive quality plays a fundamental role in its durability on the skin. Inadequate adhesive strength can cause early detachment, rendering the device unproductive. It’s not unusual for users to account for issues of the sensor detaching off shortly after application, particularly during everyday activities. 

Sweating and moisture 

Moisture, particularly due to sweating, is a common adversary to sensor adhesion. The Dexcom G7 sensor may struggle to maintain its grip on the skin when exposed to excess sweat, especially during workouts or in hot weather. This issue is compounded for individuals with active lifestyles. 

Skin sensitivity 

skin sensitivity or allergic reactions may also be faced by many people due to the adhesive used in Dexcom G7 sensors. Itching, Redness, and uneasiness can prompt users to get rid of the sensor impulsively, leading to unreliable monitoring and wrong data. 

Causes of Dexcom G7 falling off

The Dexcom G7 sensor may fall off due to several reasons. Some of the most common reasons are as follows: 

Oily skin 

People with naturally oily skin might experience difficulties with sensor adhesion. The extra oil can generate a blockade between the adhesive and the skin, falling its efficiency. This is the reason, the sensor do not adhere properly or falls off soon after its application. 

Poor application technique 

Proper application of the Dexcom G7 sensor is vital for confirming its durability. Don’t see the proper application method or failing to follow the manufacturer’s procedures can result in inadequate adhesion. Carefully cleaning the area, allowing it to dry fully, and then applying even pressure during attachment can make a significant difference. 

Physical activity 

For those who are involved in regular physical activities, the friction and movement of the body can compromise the sensor’s adhesion. High-intensity workouts or activities that involve a lot of body movement cause the sensor to peel off impulsively. 

Top tips for secure wear of Dexcom G7 

If you want your Dexcom G7 sensor to stick to your skin firmly, you can take advantage of the following tips in this regard. 

Skin preparation

Frequently Asked Questions

Why does the Dexcom G7 sensor often fall off?

The adhesive quality of the Dexcom G7 sensor is crucial for longevity on the skin. Inadequate adhesive strength can lead to premature detachment, especially during activities. Sweating, skin sensitivity, and poor application technique are also factors contributing to sensor detachment.

How does sweating affect sensor adhesion?

Excess sweat, especially during workouts, can weaken the sensor’s grip on the skin. Moisture interferes with adhesion, causing the Dexcom G7 sensor to peel off. This issue is particularly prevalent for individuals with active lifestyles.

Can skin sensitivity impact sensor adhesion?

Yes, some users experience skin sensitivity or allergic reactions to the sensor’s adhesive. This can cause discomfort, redness, and itching, leading to premature sensor removal and inaccurate data.

What causes the Dexcom G7 sensor to fall off due to oily skin?

Naturally oily skin can create a barrier between the adhesive and the skin, reducing adhesion effectiveness. The excess oil prevents the sensor from adhering properly, causing it to fall off soon after application.

How can I ensure proper application of the Dexcom G7 sensor?

Proper application is vital. Clean the area thoroughly, allow it to dry, and apply even pressure as per the manufacturer’s guidelines. Rushing or improper application can lead to inadequate adhesion.

Why might physical activity impact sensor adhesion?

Engaging in high-intensity workouts or activities with frequent body movement can compromise the sensor’s adhesion. The friction and movement from these activities can cause the sensor to peel off prematurely.
