primary diabetes mellitus

Last reviewed 01/2021

The common primary diabetes mellitus syndromes are:

  • insulin dependent diabetes mellitus (IDDM) (Type I Diabetes)
  • non-insulin dependent diabetes mellitus (NIDDM) (Type II Diabetes)

The distinction between IDDM and NIDDM is clinical:

  • if insulin therapy is required to prevent ketoacidosis the the patient has IDDM
  • if insulin therapy is not required to prevent ketoacidosis then the patient has NIDDM
  • if the patient has NIDDM but insulin is required to maintain acceptable glycaemic control then the patient has insulin-treated NIDDM

Maturity onset diabetes of the young (MODY) is a rare primary diabetes mellitus syndrome.
