Continuous Glucose Monitoring (CGM)

CGM, or Continuous Glucose Monitoring, is a way for people with diabetes to keep track of their blood sugar levels throughout the day and night. It involves using a small sensor placed under the skin that measures glucose levels in the body. This information is sent to a device, like a receiver or smartphone, which displays the readings. CGM helps people with diabetes make informed decisions about their insulin, food intake, and physical activity to effectively manage their condition.

There are normal or optimal glucose ranges that is a way for people to ensure their glucose levels stay within safe ranges.


Dr. Thomas M. Aoki is often credited with pioneering the concept of continuous glucose monitoring in the 1960s when he developed an early prototype device for measuring glucose levels continuously. Since then, companies like MiniMed (now Medtronic), Dexcom, Abbott, and Senseonics have played vital roles in developing and commercializing CGM systems that are widely used today.
