4-4-4 Sugar Challenge: A Simple At-Home Test for Sucrose Intolerance

Sucrose Intolerance caused by Congenital Sucrase-Isomaltase Deficiency (CSID) is a disorder that causes a reduction of the enzyme activity needed to break down and absorb table sugar (sucrose) and other sugars from starch. Symptoms of CSID include chronic, watery diarrhea, gassiness, bloating, abdominal pain, and even constipation. The symptoms can vary from mild to severe. Infants, children, and adults can suffer from the disease.

Diagnosing CSID can be difficult because the symptoms are similar to several other more common gastrointestinal disorders including toddler’s diarrhea, IBS-D, celiac disease, or lactose intolerance. Many people who have ongoing GI symptoms have been searching for answers for months to years, but often CSID is not considered as a possibility. Sucrase deficiency may be more common than previously thought according to recent studies. People who have chronic GI symptoms are seeking answers and may benefit from a simple test that could indicate that CSID is worth exploring as a diagnosis.
