Which hormone is deficient or ineffective in diabetes mellitus?
Correct Incorrect Diabetes mellitus is a metabolic disorder characterized by chronic hyperglycemia resulting from defects in insulin production, insulin action, or both. In type 1 diabetes, autoimmune destruction of pancreatic beta cells leads to insufficient insulin secretion. In type 2 diabetes, insulin resistance combined with inadequate compensatory insulin secretion causes elevated blood glucose levels. This dysregulation disrupts normal carbohydrate, fat, and protein metabolism, leading to acute symptoms and long-term complications. Effective management requires monitoring blood glucose, lifestyle modifications, and pharmacologic treatments tailored to the diabetes type and patient profile.
