Euglycemic hyperinsulinemia is a medical condition characterized by high levels of insulin in the blood (hyperinsulinemia) despite normal blood glucose levels (euglycemia). This state can occur due to various physiological and pathological conditions. Insulin is a hormone produced by the pancreas that helps regulate blood glucose levels. Normally, insulin levels rise in response to increased blood glucose, such as after a meal. However, in euglycemic hyperinsulinemia, insulin levels remain elevated even when blood glucose levels are normal.

One common cause of euglycemic hyperinsulinemia is intense exercise, particularly in well-trained athletes. During prolonged or high-intensity exercise, muscles utilize glucose at an increased rate, leading to a rise in insulin secretion to facilitate glucose uptake. However, if glucose consumption by the muscles outpaces glucose availability, blood glucose levels may remain normal despite high insulin levels.

Another cause is the use of certain medications, such as sulfonylureas, which stimulate the pancreas to secrete more insulin. In some cases, euglycemic hyperinsulinemia can be a sign of an underlying disorder, such as an insulinoma, a rare tumor of the pancreas that secretes excessive amounts of insulin. Other potential causes include reactive hypoglycemia, where the body overcompensates for a rise in blood glucose, leading to a subsequent drop in glucose levels and a rise in insulin.

Symptoms of euglycemic hyperinsulinemia can include sweating, shakiness, hunger, and confusion, similar to those of hypoglycemia. However, unlike hypoglycemia, blood glucose levels remain within the normal range. Diagnosis typically involves measuring blood insulin and glucose levels, often after a period of fasting or during a glucose tolerance test. Treatment depends on the underlying cause and may involve lifestyle modifications, changes in medication, or, in rare cases, surgery.
