Understanding Finger Pricks for Dexcom CGM Users

For those living with diabetes, Continuous Glucose Monitoring (CGM) systems like the Dexcom CGM have been game-changers. These devices provide real-time data on glucose levels, reducing the need for frequent finger pricks. However, there are still moments, when a Dexcom CGM user might need to test their blood glucose manually. Here's why, when, and how often this might be necessary—and how the Digivibe device by Suthe Dermal can make these finger pricks virtually pain-free.

Why Do You Need Finger Pricks with a Dexcom CGM?

ADD TO CART

Dexcom CGMs are incredibly accurate and reliable, but they aren't perfect. There are specific situations where a finger prick test is still recommended:

Calibration and Sensor Information

Calibration (For Certain Models): While newer models like the Dexcom G6 don't require calibration, some older versions may ask for occasional calibrations to ensure accuracy. This involves taking a finger prick and entering the glucose reading into the device.
Sensor Warm-Up Periods: During the warm-up period of the Dexcom sensor, no glucose readings are available. A finger prick may be necessary if you need to monitor your levels closely during this time.
Symptoms Don't Match Readings: If your symptoms (like dizziness, sweating, or confusion) don't align with the CGM readings, it's essential to double-check with a finger prick to ensure your blood glucose is at a safe level.
Sensor Issues: If your CGM sensor is malfunctioning or has been dislodged, the data might be inaccurate. A finger prick test can help verify your blood glucose levels until the sensor is replaced.
High or Low Alerts: While Dexcom CGMs provide alerts for high or low blood sugar, extreme readings may need confirmation via a finger prick, especially if the alert doesn't align with how you're feeling.

The Solution

Self-administering injections can be daunting, especially as weight loss progresses and injections become more uncomfortable. Digivibe by Suthe offers a solution by blocking injection pain and reducing anxiety, allowing you to focus on your health journey with confidence.
