Type 1 diabetes mellitus

Type 1 diabetes mellitus is a chronic autoimmune metabolic disorder characterized by the targeted destruction of insulin-producing beta cells in the pancreatic islets of Langerhans, resulting in absolute or near-absolute insulin deficiency

Although it most frequently presents during childhood or adolescence, it can develop at any age This progressive loss of endogenous insulin leads to sustained hyperglycemia, altered carbohydrate, lipid, and protein metabolism, and an elevated risk of acute life-threatening complications such as diabetic ketoacidosis, alongside long-term microvascular and macrovascular pathology
