Comprehensive Care Center for Congenital Adrenal Hyperplasia (CAH)

Weill Cornell Comprehensive Center for Congenital Adrenal Hyperplasia (CAH)

Congenital Adrenal Hyperplasia (CAH) is an inherited medical condition in which the adrenal glands do not function properly. There are several forms of CAH, all caused by different enzyme deficiencies which result in underproduction and overproduction of various hormones. Patients may not produce enough cortisol or blood sugar, or may produce high levels of androgens including testosterone. 

The Comprehensive Care Center for Congenital Adrenal Hyperplasia (CAH) healthcare team includes pediatric and adult endocrinologists, urologists, surgeons, newborn medicine specialists, nurse practitioners, patient care coordinators, dietitians, geneticists, genetic counselors, reproductive specialists and psychologists. We provide expert treatment for all classical, non-classical and rare types of CAH.

Our specialists work together to provide a comprehensive plan for your child.  We offer:

  • medical treatment from birth to adulthood
