Types of Diabetes

Diabetes is more properly called “Diabetes Mellitus”, its medical name. There are two main types of Diabetes Mellitus, which are called Type 1 Diabetes and Type 2 Diabetes. But there are various other less common forms, and there are also subtypes of those too main types too.

Main Types of Diabetes: Here are some of the main types of diabetes:

  • Type 1 Diabetes: this is also called Juvenile Diabetes, or Insulin-Dependent Diabetes Mellitus (IDDM). It is the less common form, typically affecting teenagers, but with an age rate from infants up to young adults. The prevalence is about 0.5%, i.e. about 1 in 200 people.
  • Type 2 Diabetes: this is the main type of diabetes, also known as “Adult Diabetes” or “Non-Insulin Dependent Diabetes Mellitus (NIDDM)”. It most commonly affects people in their 40’s or 50’s, but can also affect teens and younger adults (it is very unlikely in younger children). This type of diabetes affects close to 4% of the population, which means 1 in 25 people, although most of them don’t get it until their later years.
  • Pre-Diabetes: this is a mild form of Type 2 Diabetes, which is also known as Impaired Glucose Tolerance (IGT). Its symptoms are usually so mild that people are unaware of it.
  • Gestational diabetes. A type of diabetes that occurs in pregnant women. It is related to Type 2 Diabetes, but fortunately this type of diabetes usually disappears after the baby is born. The baby is not born with diabetes, and the mother should recover from diabetes (although it is more likely for the mother to get Type 2 Diabetes later in life).

Less Common Types of Diabetes: There are various less common and rare types of diabetes.

  • MODY Diabetes. A less common and less-known form of diabetes with a genetic basis.
  • Hemochromatosis-related Diabetes. This is a form of diabetes due to pancreas damage from the iron overload disease called Hemochromatosis. Read more about: Hemochromatosis.
  • Secondary Diabetes. This refers to diabetes where there is an underlying disease cause such as a pancreas disorder; read more about Misdiagnosis of Diabetes.
  • Diabetes Insipidus. This is not a type of Diabetes Mellitus. It has a similar name, even starting with the same word “diabetes” but it is actually not related to the common type of diabetes (Diabetes Mellitus). Diabetes Insipidus is a disorder of the pituitary gland and the kidneys. Its hallmark symptom is chronic urination where the urine is clear and without sugar (i.e. “insipid”). It is not related to sugar or blood glucose levels. Misdiagnosis between Diabetes Insipidus and Diabetes Mellitus is very unlikely.

Subtypes of Type 2 Diabetes: There are various types of Type 2 Diabetes!
