Congenital sucrase-isomaltase deficiency

How is congenital sucrase-isomaltase deficiency (CSID) diagnosed?

CSID can be diagnosed by taking a small sample of tissue (biopsy) from the small intestine for a specific test known as a disaccharidase assay. Other tests may include a sucrose hydrogen breath test in which an abnormally high level of hydrogen will be detected in the breath of an affected individual after sucrose ingestion. Genetic testing may be indicated in some cases.

How might congenital sucrase-isomaltase deficiency (CSID) be treated?

CSID is typically treated by modifying a person's diet to reduce the amount of sucrose. Because many foods contain sucrose and other complex sugars, it can be difficult to completely remove sucrose from the diet. Sacrosidase is an oral medication containing the enzyme that does not work properly in people with this condition. By taking this medication, those with CSID can eat sucrose-containing foods because this enzyme will break down sucrose. This medication must be taken with each meal or snack.
