Diabetes is a chronic metabolic disorder characterized by high blood sugar levels over a prolonged period. It comes in two primary forms: Type 1 and Type 2. Type 1 diabetes is an autoimmune condition where the body's immune system attacks insulin-producing cells in the pancreas. Type 2 diabetes is more common and is often associated with lifestyle factors such as obesity, lack of exercise, and poor diet. It occurs when the body becomes resistant to insulin or when the pancreas fails to produce enough insulin.
