Continuous Glucose Monitor

A Continuous Glucose Monitor (CGM) is a wearable medical device that measures glucose levels in interstitial fluid throughout the day and night. It typically consists of a small sensor inserted under the skin, a transmitter, and a receiver or smartphone app to display the data.

CGMs are primarily used by individuals with diabetes to track their blood sugar trends, identify patterns, and make informed decisions about diet, exercise, and medication. They provide real-time glucose readings and alerts for high or low levels, helping users and healthcare providers manage the condition more effectively.
