Diabetes or Diabetes Mellitus is a chronic disease that occurs when the pancreas is no longer able to make insulin, or when the body cannot make good use of insulin that it produces. The common types of diabetes are:


This is a condition in which your immune system destroys insulin-making cells in your pancreas. As a result, the body produces no or very little insulin. Type 1 diabetes is seen in people of all age groups, however, it is common in youngsters or individuals below the age of 18. People with type 1 diabetes have to take insulin every day. Type 1 diabetes is present in approximately 10% of people with diabetes.


This is the most common type of diabetes and accounts for 90% of all diabetes cases. It is generally found in middle-aged and older people. Presently, type 2 diabetes is seen in young people due to rising levels of obesity, inactivity, sedentary lifestyle, and poor eating habits. In type 2 diabetes, the body either does not produce enough insulin or does not respond to insulin. As insulin is not produced properly, the blood glucose level keeps on rising, which releases more insulin. This leads to exhaustion of the pancreas, leading to the production of less insulin and increased blood glucose levels.


This type of diabetes is seen in pregnant women and leads to complications in both mother and child and is almost cured after childbirth. GDM predisposes the mother and child to the risk of developing type 2 diabetes later in life.


It is also known as borderline diabetes. In this, blood sugar levels are higher than the normal range, but it is not high enough to be classified as type 2 diabetes. It is a warning sign of the onset of diabetes in a person.
