Insulin is a hormone that the body produces in the pancreas. It allows the body to generate energy from glucose. The body is constantly using energy — whether that’s walking, typing, exercising, or thinking. Every action requires energy, and insulin helps the body metabolize glucose into energy.
Because these levels are continuously fluctuating, the pancreas is constantly producing insulin to account for the body’s changing needs. However, for someone living with diabetes, their pancreas either does not produce insulin or the body does not use the insulin efficiently.
