How do continuous glucose monitors work?

Hello,

Welcome to icliniq.com.

I read your query and can understand your concern.

Using a continuous glucose monitor can be a highly effective way to manage diabetes.

A small sensor is inserted under the skin, typically on the abdomen or the back of the upper arm. The sensor measures glucose levels in the interstitial fluid. The sensor is connected to a transmitter that sends glucose data wirelessly to a receiver or a compatible device, such as a smartphone. The glucose levels are displayed in real-time on the receiver or device, allowing for continuous monitoring throughout the day and night.

The benefits of using CGMs are:

1. Many CGMs have customizable alerts to notify you when your glucose levels are too high or too low.

2. Continuous data helps you quickly identify and respond to blood sugar fluctuations.

3. Using a CGM can lead to significant improvements in HbA1c (glycated hemoglobin) levels.

4. Alerts help in preventing and managing hypoglycemic episodes.

5. CGMs can provide valuable insights into how diet, exercise, stress, and other factors affect your glucose levels.

6. It reduces the need for frequent finger stick tests.

I hope this helps.

Thank you and take care.

Regards.
