Mission
Congenital Hyperinsulinism International (CHI) is a nonprofit 501(c)(3) corporation dedicated to improving the lives of babies, children, and adults affected by congenital hyperinsulinism (HI). HI is a life-threatening genetic disorder that causes severe low blood sugar (hypoglycemia) in infants and children, though in 50% of patients, the genetic cause is unknown. For those with HI, the beta cells of the pancreas secrete too much insulin in an unregulated manner. Excess insulin causes hypoglycemia. Prolonged or severe hypoglycemia can cause seizures, permanent brain damage, or even death if left untreated. A good prognosis is far more likely with a timely diagnosis and proper management.
