The level of glucose in the blood, commonly known as blood sugar, is a key indicator of health. It acts as the main source of fuel for our cells, especially brain cells.

Glucose, derived primarily from the foods we eat, including carbohydrates such as grains, fruits, vegetables, and sugar, is broken down and enters our bloodstream. It is also made by our liver in a process called gluconeogenesis.

The balance of glucose in the blood is controlled by a complex system involving several hormones, mainly insulin and glucagon, which are produced by the pancreas. After a meal, the blood glucose level rises, signaling the pancreas to produce insulin. This insulin then functions to facilitate the absorption of glucose into our cells, where it is used for energy or stored for later use.

When blood glucose levels drop, the pancreas releases glucagon, which prompts the release of stored glucose back into the blood.

Persistently high blood glucose, a condition known as hyperglycemia, can lead to health complications such as diabetes, heart disease, kidney disease, and more. Conversely, hypoglycemia, or extremely low blood glucose, can lead to a range of symptoms, including weakness, confusion, and in severe cases, loss of consciousness.

Blood glucose control is especially important for people with diabetes. This is where CGMs play an important role, as they provide real-time data on glucose levels, helping people better manage their health.
