Type 1 diabetes is a disease in which the pancreas does not produce any insulin. Insulin is a hormone that helps your body to control the level of glucose (sugar) in your blood. Without insulin, glucose builds up in your blood instead of being used for energy.

Your body produces glucose and also breaks down carbohydrates and starches into glucose from foods like bread, potatoes, rice, pasta, milk and fruit. The cause of type 1 diabetes remains unknown. It is not caused by eating too much sugar and is not preventable. The current thought is that type 1 diabetes occurs when the body’s immune system destroys the cells that make insulin.
