Overeating and a high carbohydrate diet are risk factors that lead to the development of hyperinsulinemia. Insulin is a hormone that is produced by the pancreas in normal amounts. When people consume too much carbohydrate, the pancreas has to compensate by secreting higher quantities of insulin in order to regulate blood glucose levels.
Insulin is normally used for glucose metabolism. Hyperinsulinemia could also occur when the body cannot effectively use insulin due to resistance. In this case, insulin levels accumulate and pile up all because of resistance.
