Hyperinsulinism Center

doctor and patient hyperinsulinism checkupHyperinsulinism is a rare, severe genetic disorder that can cause hypoglycemia (low blood sugar) in infants and children.

Infants with untreated congenital hypoglycemia are at risk for seizures or even permanent brain damage. Congenital hyperinsulinism (CHI) is the most common cause of hypoglycemia in infants more than 3 days old. Therefore, early intervention is a very important factor in preventing irreversible damage and improving quality of life. As one of only 2 programs dedicated to the diagnosis and treatment of hyperinsulinism in the U.S., the Cook Children's Hyperinsulinism Center offers the state-of-the-art technology, advanced medical treatments and the very best care available to patients and families facing this diagnosis.

Our experience

Our medical team 

Children who are newly diagnosed with hyperinsulinism are admitted to Cook Children's Medical Center to receive a comprehensive medical evaluation. The medical staff will work closely with the family and the patient to teach them the skills necessary to manage the disease in their daily life. After leaving the medical center, routine follow-up care will continue in an outpatient specialty clinic. Depending on the type of hyperinsulinism and the treatment plan, the initial admission is two weeks to three months.

What we treat

There are many forms of CHI with more being discovered each year. Typically, 60 percent of patients with genetic forms will present in the first week of life with hypoglycemia. Early identification and treatment of these genetic forms of CHI is critical to preventing long-term effects. Because the treatment of each form of this disorder is different, it is crucial to diagnose the exact form of CHI, which may include:
