Fructose malabsorption is a digestive disorder when absorption of fructose is impaired. This results in an increased concentration of fructose in the intestine. Occurrence is often seen in patients identified to be suffering symptoms of irritable bowel syndrome (IBS). However, due to the similarity in symptoms, patients with fructose malabsorption often fit the profile of those with irritable bowel syndrome. A small proportion of patients with both fructose malabsorption and lactose intolerance also suffer from celiac disease.
