People whose blood contains more glucose than normal, but less than occurs in diabetes, may be diagnosed with a condition called impaired glucose tolerance (IGT).
Some women experience a rise in their blood glucose level during pregnancy. These women have a condition called gestational diabetes mellitus (GDM). Their blood glucose levels usually return to normal after their babies are born. Other types of diabetes may occur as a result of diseases of the pancreas or the endocrine (gland) system, genetic disorders, or exposure to chemical agents.
