How diabetes develops

Glucose is essential for the body because it provides energy. Insulin carries glucose from the bloodstream into the body’s cells. When insulin is absent or insufficient, or when the body’s cells do not respond properly to insulin, glucose builds up in the blood, leading to diabetes.

Type 1 Diabetes

Type 1 diabetes is most commonly diagnosed in children and teenagers. It occurs when the body’s immune system destroys insulin‑producing cells in the pancreas, leading to an absolute lack of insulin.

Type 2 Diabetes

Type 2 diabetes is the most common form, affecting over 95% of adults with diabetes. It occurs when the pancreas does not produce enough insulin or when the body becomes resistant to insulin. It is strongly associated with obesity and lifestyle factors.

Gestational Diabetes

Gestational diabetes occurs during pregnancy due to hormonal and metabolic changes. While usually temporary, it increases the risk of Type 2 diabetes later in life.
