Sucrose intolerance

Sucrose intolerance, also called Congenital Sucrase-Isomaltase Deficiency (CSID) or Sucrase-isomaltase deficiency, is the condition in which sucrase, an enzyme needed for proper metabolization of sucrose, is not produced in the small intestine. The result of consuming sucrose is excess gas production and often diarrhea and malabsorption.
