Congenital hyperinsulinism is caused by genetic mutations that result in inappropriate and excess insulin secretion from the beta cells of the pancreas. (chop.edu)
The most common and severe form of congenital hyperinsulinism is due to inactivating mutations of two genes that encode subunits of the beta-cell K ATP channel, leading to dysregulated insulin secretion. (medscape.com)
Congenital hyperinsulinism is a condition of dysregulated insulin secretion often caused by inactivating mutations of the ATP-sensitive K+ (KATP) channel in the pancreatic β cell. (jci.org)
However, children with persistent hyperinsulinism may have a genetic defect that results in inappropriate secretion of insulin. (medscape.com)
Hyperinsulinism can be associated with several types of medical problems, which can be roughly divided into two broad and largely non-overlapping categories: those tending toward reduced sensitivity to insulin and high blood glucose levels ( hyperglycemia ), and those tending toward excessive insulin secretion and low glucose levels ( hypoglycemia ). (ipfs.io)
Hyperinsulinism may also refer to forms of hypoglycemia caused by excessive insulin secretion. (ipfs.io)
The treatment of this form of hyperinsulinism depends on the cause and the severity of the hyperinsulinism, and may include surgical removal of the source of insulin, or a drug such as diazoxide or octreotide that reduces insulin secretion. (ipfs.io)
