What is the Function of Insulin?

When you enjoy a hearty meal, your body breaks down the food into many components, including glucose. When your blood glucose level rises, it signals your pancreas to secrete insulin. Insulin signals your cells to allow glucose to leave the blood and enter the cells to provide energy for the body. The most common disease associated with an insulin disorder is diabetes. In Type 1 diabetes, your pancreas does not produce its own insulin. Those afflicted must constantly check their blood sugar and take insulin shots when appropriate.
