hyperinsulinism

Increased levels of insulin in the plasma due to increased secretion of insulin by the beta cells of the pancreatic islets; decreased hepatic removal of insulin is a cause in some patients, although h. usually is associated with insulin resistance and is commonly found in obesity in association with varying degrees of hyperglycemia. SYN: hyperinsulinemia.
- alimentary h. elevated levels of insulin in the plasma following ingestion of meals by individuals with abnormally rapid gastric emptying ( e.g., following gastroenterostomy or vagotomy); rapid glucose absorption leads to excessive insulin release which in turn can lead to a marked fall in blood glucose to hypoglycemic levels.
