What is hyperinsulinemia?

• A. Chronic and acute elevation of insulin due to excess simple carbs (pre-diabetes)
• B. Low insulin levels during fasting
• C. Normal insulin secretion after meals
• D. High glucose without insulin response

Answer: (B)

Hyperinsulinemia means there is more insulin in the blood than normal. This often happens when the body's tissues become less responsive to insulin (insulin resistance), so the pancreas keeps producing extra insulin to try to move glucose into cells. You can see elevated insulin levels even in the fasting state when resistance is present, not just after meals. After a meal, insulin normally rises to help glucose enter cells; in hyperinsulinemia those levels can be disproportionately high because the pancreas overcompensates.

This is not described by low insulin during fasting or by a normal post-meal secretion. It’s also not defined by high glucose with no insulin response, which would indicate insulin deficiency rather than excess insulin.
