	'''Hyperinsulinism''' is a condition characterized by an excess of [[insulin]] in the [[bloodstream]]. This condition can lead to various metabolic disturbances, primarily affecting the regulation of [[blood glucose]] levels. Hyperinsulinism can be caused by several factors, including [[insulinoma]], [[congenital hyperinsulinism]], and [[reactive hypoglycemia]].

	==Pathophysiology==		==Pathophysiology==
	Hyperinsulinism occurs when there is an overproduction of insulin by the [[pancreas]], or when the body's tissues are overly sensitive to insulin. Insulin is a hormone produced by the [[beta cells]] of the [[islets of Langerhans]] in the pancreas. It plays a crucial role in regulating blood glucose levels by facilitating the uptake of glucose into cells for energy production or storage as [[glycogen]].

Insulin is a hormone produced by the [[beta cells]] of the [[islets of Langerhans]] in the pancreas. It plays a crucial role in regulating blood glucose levels by facilitating the uptake of glucose into cells for energy production or storage as [[glycogen]].

	In hyperinsulinism, the excessive insulin levels cause blood glucose to be taken up by cells at a higher rate than normal, leading to [[hypoglycemia]], or low blood sugar levels. This can result in symptoms such as [[dizziness]], [[sweating]], [[confusion]], and in severe cases, [[seizures]] or [[coma]].
