Diabetes is a group of metabolic diseases in which a person has high blood sugar, either because the body does not produce enough insulin, or because cells do not respond to the insulin that is produced. This high blood sugar produces the classical symptoms of polyuria (frequent urination), polydipsia (increased thirst) and polyphagia (increased hunger). Research on Diabetes provides the latest research and development in the area of diabetes by presenting a succinct review of the works that researchers struggling to find answers for 200 million diabetics world-wide, where the number of those afflicted is expected to double, if not triple, in coming decades.
