Type 1 diabetes is an autoimmune disease that occurs when the immune system attacks the insulin-producing beta cells in the pancreas. Due to this attack, the pancreas either produces no insulin at all or an insufficient amount. As the body cannot meet its vital insulin needs, individuals with type 1 diabetes must take external insulin injections throughout their lives.
Genetic predisposition plays a significant role in the development of the disease, and some environmental factors, stress, and trauma are also thought to be potential triggers. Type 1 diabetes, which accounts for approximately 10% of diabetes cases, is usually diagnosed in childhood but can appear at any age.
