Diabetes is a chronic condition affecting millions worldwide, characterized by the body’s inability to regulate blood sugar effectively. It occurs when insulin, a hormone produced by the pancreas, is insufficient or the body’s cells become resistant to its effects. This leads to elevated glucose levels, which, if left untreated, can cause severe health complications. Understanding the causes of diabetes—ranging from genetic predisposition and autoimmune factors (Type 1) to lifestyle choices and insulin resistance (Type 2)—is crucial for prevention and management.
