Overview of Diabetes Mellitus and its Prevention

High blood glucose levels caused by deficits in either insulin action or synthesis, or both, are a hallmark of diabetes mellitus, a chronic metabolic disorder. The two primary types of diabetes are Type 1 diabetes, an autoimmune condition that kills beta cells that make insulin, and Type 2 diabetes, which is mostly caused by insulin resistance and insufficient insulin production. Diabetes is becoming more and more common worldwide, mostly as a result of lifestyle choices like obesity, poor food, and inactivity. Diabetes can cause major side effects like blindness, kidney failure, neuropathy, and cardiovascular disease if it is not controlled. In order to lessen the burden of diabetes, preventive measures are essential. These consist of lifestyle changes such eating a healthy diet, exercising frequently, controlling one's weight, and identifying people who are at risk early. Fighting the rising diabetes epidemic requires public health programs that emphasize healthcare access, education, and awareness. This review summarizes the pathophysiology, risk factors, and preventative strategies of diabetes mellitus, emphasizing the importance of early intervention and lifestyle modifications.
