Which organ has the greatest impact on insulin metabolism, contributing to hypoglycemia risk in renal disease?

• A. Kidney
• B. Liver
• C. Pancreas
• D. Adrenal gland

Answer: (A)

Insulin clearance is a two-pronged process, with both the liver and the kidneys helping remove insulin from the circulation. In renal disease, the kidneys’ ability to degrade and clear insulin is impaired, so insulin stays in the bloodstream longer and continues to act. This prolonged action increases the risk of hypoglycemia, especially after insulin administration or during fasting, which is a particular concern in patients with reduced kidney function. Although the liver normally handles a large portion of insulin clearance, the loss of renal clearance becomes especially impactful in renal disease, making the kidney the organ whose dysfunction most directly raises hypoglycemia risk in this context.
