Diabetes mellitus: Types, Causes, Diet, Treatment

Diabetes mellitus is a metabolic disorder and is characterized by high sugar(glucose) levels in the blood.

It is mainly caused by two mechanisms:

  1. The body produces an insufficient amount of insulin
  2. The body produces insulin but many cells in the body fail to respond to it.

Insulin: insulin is a hormone that is produced by the pancreas, a gland located behind the stomach. The role of insulin is to use the glucose present in the body for energy.


It is mainly of two types

  • Type 1
  • Type 2

Type 1 diabetes: it is a condition when the body fails to produce a sufficient amount of insulin. It is mainly due to an autoimmune disease, a condition when the immune system in the body mistakenly attacks the pancreas that produces insulin.

Type 2 diabetes: it is a condition when beta cells in the pancreas are able to produce insulin but the body does not use insulin efficiently. This is also known as “insulin resistance”.


The causes of diabetes may vary with the type.

The cause of type 1 diabetes is unknown, but the body’s own immune system, which usually helps to prevent the body from harmful bacteria and viruses mistakenly attacks the beta cells in the pancreas that produce insulin.

Type 2 diabetes may be caused by:

  • Obesity or overweight
