Fructose intolerance

Fruktoseintoleranz·Also: Fruchtzuckerunverträglichkeit

In fructose intolerance, the body has difficulty tolerating fruit sugar. After eating it, abdominal pain, bloating and diarrhoea may occur. A distinction must be made between the more harmless absorption disorder and the rare hereditary form.
