Type 1 diabetes (type 1 diabetes mellitus) is a long-term, or chronic, disease. It occurs when the cells in the pancreas (beta cells) that make a hormone called insulin are destroyed. Normally, insulin allows blood sugar, also called glucose, to enter cells in the body. The cells use glucose for energy. Lack of insulin causes excess glucose to build up in the blood instead of going into cells. As a result, high blood glucose, or hyperglycemia, develops.
There is currently no cure for type 1 diabetes, but it can be managed with insulin therapy and lifestyle changes.
The exact cause of type 1 diabetes is not known.
