Hyperinsulinemia is a condition in which the level of insulin in the blood is higher than the normal range. The specific diagnostic criteria for hyperinsulinemia are as follows: 1. fasting insulin greater than or equal to 85 pmol/L. 2. hypoglycemia and relative hyperinsulinemia disproportionate to blood glucose levels occur. 3. there are often manifestations of significant insulin resistance, such as acanthosis nigricans. Hyperinsulinemia is usually associated with insulin resistance and diabetes. Hyperinsulinemia is usually an early manifestation of metabolic disease and is usually seen in overweight and obese people with high levels of body fat. However, it can also be seen in people with diseases such as islet cell tumors and congenital hyperinsulinemia. Patients with abnormal insulin or blood glucose values should consult a doctor in time to clarify the cause and treatment under the guidance of a professional doctor.
