Hypoglycemia (Hypoglycaemia in British English) is the meical term for a pathologic state produced by a lower than normal level of glucose (sugar) in the blood. The term hypoglycemia literally means "under-sweet blood" (Gr. hypo-, glykys, haima). The term also refers to a putative condition that is scientifically disputed and which is perhaps more properly considered as a part of "alternative" medicine. This is covered at the end of this article.
