There are three main types of diabetes:

1. Type 1 diabetes mellitus(T1DM)

2. Type 2 diabetes mellitus (T2DM)

3. Gestational diabetes mellitus (GDM)


In type 1 diabetes, the body does not produce insulin due to damage caused to the insulin producing cells (beta cells) of the pancreas. It can affect people of any age, but is commonly seen in children or young adults. People with type 1 diabetes need to take insulin every day in order to maintain their blood glucose levels.

The onset of type 1 diabetes is sudden in most cases.


Type 2 diabetes (also known as adult-onset diabetes) is the most common form of diabetes (accounting for 90% of all cases of diabetes). It usually occurs in adults, but is also seen in children and adolescents.

In type 2 diabetes, the body is either not able to produce enough insulin or is unable to use it properly which is known as "insulin resistance".

Initially, the pancreas tries to keep up with the added demand by producing more insulin but over time, it loses the ability to secrete enough insulin in response to meals. This leads to accumulation of glucose in the blood.

Many people with type 2 diabetes may remain unaware of their condition for years as the symptoms become apparent over a period of time.


Gestational diabetes mellitus (GDM) is a form of diabetes which occurs in pregnant women who have never had diabetes before but who have high blood glucose levels during pregnancy. It occurs usually around 24th week of pregnancy and affects 18% of pregnant women worldwide.

Gestational Diabetes Mellitus

Although, GDM usually disappears after pregnancy but the women with GDM and their children are at higher risk of developing type 2 diabetes later in life.

Approximately, 50% of women with a history of GDM go on to develop type 2 diabetes within 5-10 years after delivery.

This is important information!

All pregnant women should be screened for GDM between 24 and 28 weeks of pregnancy. If you are pregnant, make sure to talk to your doctor about being tested for GDM.
