Living with CSID

CSID a Rare Congenital Disorder of the Small Intestine

Congenital Sucrase-Isomaltase Deficiency or CSID is a congenital disease similar to lactose intolerance, but for sucrose, a common form of sugar. The body lacks the primary enzyme in the small intestine responsible for digesting sucrose. Symptoms often overlap with many common GI disorders so it can be difficult to diagnose. Join guests, Dr. William Treem, a pediatric gastroenterologist, a CSID patient and a CSID advocate as they discuss the problem—its symptoms, diagnosis, and treatment.
