What do diabetics put on their arm?

Diabetics typically wear a device on their arm known as a continuous glucose monitor (CGM). This is a small device that is worn on the outside of the arm, usually near the elbow. It measures the changing levels of glucose in a diabetic’s blood and sends data to an app or website.

CGMs provide quick and frequent updates, allowing the user to better manage their diabetes. They come with a tiny wire that is inserted underneath the skin, typically on the upper right arm, and sends data to a receiver.

This data is used to adjust diet and insulin levels as needed and is crucial to helping keep diabetes under control.
