1. Type 1 Diabetes: This is an autoimmune condition in which the immune system attacks and destroys the insulin-producing cells in the pancreas. People with type 1 diabetes require insulin injections or an insulin pump to manage their blood sugar levels. It often develops in childhood or early adulthood and cannot be prevented.
2. Type 2 Diabetes: This is the most common type of diabetes and usually develops over time. It is often associated with lifestyle factors such as obesity, physical inactivity, and poor diet. In type 2 diabetes, the body becomes resistant to insulin, and the pancreas may not produce enough insulin to compensate. Initially, lifestyle changes and oral medications are often used to manage blood sugar levels. In some cases, insulin injections might also be necessary.
3. Gestational Diabetes: This type occurs during pregnancy when the body cannot produce enough insulin to meet the increased needs. It usually resolves after childbirth, but women who have had gestational diabetes are at higher risk of developing type 2 diabetes later in life.
