Insulin is a hormone that helps glucose get into your cells to give them energy. With type 1 diabetes, your body does not make insulin. With type 2 diabetes, the body either doesn’t produce enough insulin, or it resists insulin. Maintaining a healthy diet and exercise regimen is critical for patients with both types of diabetes.
