What is Diabetes Mellitus? Diabetes mellitus, commonly referred to as diabetes, is a chronic metabolic disorder characterized by hyperglycemia (elevated blood glucose levels). This condition results from a complex interplay of genetic, environmental, and lifestyle factors that impact insulin production or utilization. In this in-depth exploration, we will dissect diabetes in medical terms, covering its definition, types, pathophysiology, causes, and the intricacies of its management and treatment. Definition of Diabetes: Diabetes is a metabolic disorder characterized by the body's inability to regulate blood glucose levels effectively. This dysfunction may arise due to insufficient insulin production, inadequate cellular response to insulin, or a combination of both. Insulin, a hormone produced by the pancreas, plays a pivotal role in glucose metabolism, facilitating its entry into cells for energy utilization. Types of Diabetes: Type 1 Diabetes Mellitus (T1DM): Autoimmune destruct
