Have you heard of sucrose intolerance (congenital sucrase isomaltase deficiency [CSID])?⁠⠀
⁠⠀
CSID was once thought to be quite rare, however as the practice of gastroenterology expands, we are realizing that patients can exist on a spectrum. While still rare, some patients are being diagnosed in adulthood.⁠⠀
⁠⠀
CSID is the reduced or absent production of the enzymes sucrase and isomaltase, responsible for breaking down sucrose and isomaltose, carbohydrates frequently found in our foods. ⁠⠀
⁠⠀
Patients with CSID are typically diagnosed in childhood, however, this is not always the case. ⁠⠀
⁠⠀
Symptoms include bloating, abdominal pain, and diarrhea but may also include reflux, nausea, and vomiting – which often means patients can go undiagnosed or misdiagnosed for a period of time. ⁠⠀
⁠⠀
CSID is best diagnosed by a small bowel biopsy, however there is also a clinically validated breath test that can be used to diagnose CSID.⁠⠀
⁠⠀
Patients with CSID often use enzyme replacement therapy, as well as dietary measures to manage symptoms. Many times this isn’t all-or-nothing, but rather figuring out how much of these specific carbohydrates you can tolerate.⁠⠀
