Diabetes Type

Types of diabetes

Diabetes mellitus is a heterogeneous group of disorders characterized by high blood glucose levels. This abnormal rise in blood glucose levels is due to either insulin deficiency or the resistance of the body’s cells to the action of insulin. The World Health Organization (WHO) defines four major types of diabetes.

Classification of Diabetes mellitus

It is classified based on the cause or mode of treatments;

  1. Insulin-dependent diabetes mellitus (IDDM) - need insulin shots to maintain the blood glucose level,
  2. Non-insulin-dependent diabetes mellitus (NIDDM) - insulin shots are not the must to normalize the glucose level,
  3. Gestational diabetes mellitus (GDM) - diabetes develops during pregnancy and mostly disappears after delivery,
  4. secondary to other conditions (e.g., pancreatic disease, Hormonal disease, Drug or chemical exposure, Insulin receptor abnormalities, specific genetic syndromes).

Diagnosis of diabetes is by the presence of the classic signs & symptoms and unequivocally elevated blood-glucose levels, by fasting plasma glucose (FPG) 140 mg/dl, or by venous plasma glucose 200 mg/dl at 2 hours after a 75-g oral glucose challenge.

There are two major types of diabetes

Two primary classifications of Diabetes are:

  • Type 1 diabetes or insulin-dependent diabetes mellitus (IDDM) or juvenile diabetes, the pancreas is failed to produce the hormone insulin. Resulting in high blood-glucose level and so, the patients need insulin shots.
  • Type 2 diabetes or non-insulin-dependent diabetes mellitus (NIDDM) or insulin resistance, the pancreas does produce insulin, but insufficient quantity or body become insensitive to insulin (insulin resistance). Type 2 diabetes is prevalent, particularly among older adults.

Subdivisions in Type 2 diabetes

  • pre-diabetes - blood glucose is higher than usual but not high enough to diagnose as diabetes. You can reverse borderline diabetes with proper food and physical activities. 
  • Gestational diabetes - develops during pregnancy due to hormonal changes that occur naturally during pregnancy.
