Lack of Insulin Production
Insulin is a hormone that is produced by specialized cells (beta cells) in the pancreas. It and is then released into the bloodstream. Insulin is required to allow glucose (sugar) to enter the cells in the body to be used for energy. The pancreas of a person with type 1 diabetes produces no insulin, so the cells are unable to convert blood glucose into energy.
