What can the Magen-Darm-Gesundheit tell you — and what not?

The MyBody-X Magen-Darm-Gesundheit (gut health) test can provide insights into the composition of the gut microbiome or measure IgG antibodies against foods. What it cannot do: It is not a diagnostic tool for conditions like IBS, celiac disease, or inflammatory bowel disease. Scientific evidence for IgG-based food intolerance tests is weak; major allergy societies (e.g., EAACI, German S2k guideline, PMID:37705676) advise against their clinical use. DNA-based predictions for gut health also have limited accuracy – most genetic variants have small effects, and lifestyle factors (diet, stress) are more influential. The test may show trends but should not guide individual medical decisions. Without medical consultation, drastic dietary changes are not recommended. Results should be seen as complementary information, not a substitute for professional diagnosis.
