Which term indicates excessive secretion of insulin into the bloodstream?

• A. Hyperglycemia
• B. Hypoglycemia
• C. Pancreatitis
• D. Hyperinsulinism

Answer: (D)

Excess insulin in the bloodstream is called hyperinsulinism. Insulin lowers blood glucose by helping cells take up glucose from the blood, so when too much insulin is secreted, blood sugar drops below normal, leading to hypoglycemia. Hyperglycemia means high blood sugar, pancreatitis is inflammation of the pancreas, and hypoglycemia describes the low blood sugar state (often a result of excess insulin) rather than the secretion itself.
