Congenital Sucrase-Isomaltase Deficiency (CSID)
CSID Outreach and Education Program
ANTHC’s Congenital Sucrase-Isomaltase Deficiency (CSID) Program provides education, resources, and support for patients, caregivers, and health care providers throughout Alaska. The program collaborates with Tribal Health Organizations to assist with processes for diagnosis and management of CSID.
What Is CSID?
CSID stands for Congenital Sucrase-Isomaltase Deficiency. CSID is a genetic change a person is born with that makes it hard to digest sugar and starch. The type of sugar that is hard to digest is sucrose, also known as table sugar.
Our bodies use digestive enzymes to help break down food. The enzyme that helps break down sucrose and starch is called sucrase-isomaltase. In a person with CSID, the body may not have enough of this enzyme to break down sucrose and starch.
