PATHOPHYSIOLOGY OF DIABETES AND METABOLIC DISORDERS

This research paper focuses on the pathophysiological mechanisms and metabolic disturbances associated with diabetes mellitus, a globally prevalent chronic disease that significantly affects public health. The study delves into both Type 1 and Type 2 diabetes, highlighting their distinct etiologies autoimmune β-cell destruction and insulin resistance, respectively and the common consequence of chronic hyperglycemia. The paper explains how insulin deficiency or resistance leads to disrupted carbohydrate, lipid, and protein metabolism, resulting in systemic imbalances that impact multiple organ systems. Particular attention is paid to the processes of gluconeogenesis, lipolysis, ketogenesis, and proteolysis, which are amplified in the diabetic state. These alterations contribute not only to the clinical symptoms of diabetes but also to the development of serious complications such as nephropathy, neuropathy, retinopathy, and cardiovascular disease. By analyzing the molecular and cellular mechanisms involved, the paper provides a comprehensive understanding of how metabolic dysregulation occurs and progresses in diabetic patients.
