Can fructose intolerance cause irritable bowel syndrome?

Answers from Michael F. Picco, M.D.

Fructose is the natural sugar in fruit. Fructose is also found in sweeteners such as high-fructose corn syrup. Fructose intolerance can cause bloating and diarrhea in some people. Although these symptoms may be confused with irritable bowel syndrome (IBS), fructose intolerance isn't thought to cause IBS. It's important to note, however, that people who have IBS may be more susceptible to bloating and diarrhea from fructose. In this case, reducing or eliminating fructose from your diet may ease your symptoms.
