Final answer:
Type 1 diabetes, also known as juvenile diabetes or type 1 diabetes mellitus, is an autoimmune disease where the immune system attacks and destroys the insulin-secreting beta cells in the pancreas. This results in a lack of insulin production, which is needed to regulate blood glucose levels. The cause of type 1 diabetes is not fully understood, but it is believed to involve a combination of genetic and environmental factors.
