Fructose-Malabsorption

Evaluation of possible fructose malabsorption in cases of recurring gastrointestinal complaints such as bloating, abdominal pain, or diarrhea after consuming fructose-containing foods.

H₂ breath test (hydrogen breath test): After administration of a defined fructose solution, the hydrogen content of the exhaled air is measured at regular intervals. An increase indicates insufficient absorption of fructose in the small intestine.

Approx. 120–180 minutes

More detailed information will be provided during the pre-consultation by one of our physicians.

Evaluation of the test results and medical consultation. Values above 20 ppm are considered positive and indicate fructose intolerance. If needed, recommendations for further nutritional therapy (e.g., an elimination model) and, if necessary, follow-up testing.
