As a clinician you probably encounter patients complaining of bloating, gas, abdominal pain, or bouts of diarrhea on a daily basis, where it may be difficult to arrive at a definitive diagnosis. Sometimes the patients’ symptoms have been going on for years, and they may have seen multiple specialists. The patients may have also tried their own interventions, including taking probiotics, or eliminating gluten and milk from their diet, but are still experiencing frequent symptoms.
For these patients, you might have a routine checklist you go through to narrow down the possible diagnoses. First you rule out symptoms that point to more severe diseases, such as cancer and inflammatory bowel disease. Then you may consider the more common disorders, such as lactose intolerance and irritable bowel syndrome. Genetic Sucrase-Isomaltase Deficiency (GSID) might not be on the list of diagnoses that you consider, or maybe you are not familiar with GSID. The purpose of this booklet is to raise your awareness of the clinical presentation, diagnosis, and management of GSID.
