'''Diabetes mellitus''' stands as a chronic medical condition characterised by heightened levels of blood glucose ([[hyperglycaemia]]) stemming from deficiencies in insulin secretion, insulin action, or a confluence of both factors. Insulin, a hormone manufactured by the pancreas, assumes a pivotal role in regulating blood sugar levels. Diabetes may precipitate various complications that impact diverse organ systems. Effective management involves lifestyle modifications, pharmaceutical interventions, and, in certain instances, insulin therapy.
