Type 1 diabetes can occur at any age. It is most often diagnosed in children, adolescents, or young adults.
Insulin is a hormone produced in the pancreas by special cells called beta cells. The pancreas is behind the stomach. Insulin is needed to move blood sugar (glucose) into cells. There, it is stored and later used for energy. With type 1 diabetes, beta cells produce little or no insulin.
Without enough insulin, glucose builds up in the bloodstream instead of going into the cells. The body is unable to use this glucose for energy. This leads to the symptoms of type 1 diabetes.
The exact cause of type 1 diabetes is unknown. Most likely it is an autoimmune disorder. This is a condition that occurs when the immune system mistakenly attacks and destroys healthy body tissue. With type 1 diabetes, an infection or another trigger causes the body to mistakenly attack the cells in the pancreas that make insulin. Type 1 diabetes can be passed down through families.
