Hyperinsulinemia

Abnormally elevated insulin concentrations in the blood (normal range: 2-25 μU/mL, optimal: <10 μU/mL, moderate: 10-15 μU/mL, hyperinsulinemia: ≥15-25 μU/mL). Possible causes are insulin resistance, metabolic syndrome, obesity, high calorie intake, compensatory beta-cell hypersecretion, insulinoma, nesidioblastosis, gastric bypass altering the insulin clearance, and medications.
