After exclusion of a small intestinal bacterial overgrowth by a glucose breath test, fructose malabsorption was assessed by a five\u2010hour breath test, with symptom monitoring, after a 25\u2009g load of fructose. An increase of more than 20\u2009ppm of hydrogen (H<jats:sub>2<\/jats:sub>) or methane (CH<jats:sub>4<\/jats:sub>) levels in the exhaled air led to the diagnosis of malabsorption.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Fructose test was abnormal in 20\/90 patients among whom only 35% were intolerant, with a simultaneous rise of H<jats:sub>2<\/jats:sub> \/CH<jats:sub>4<\/jats:sub> levels and the onset of abdominal discomfort or diarrhoea.
