was hilft gegen bauchschmerzen — can a DNA test help?

DNA tests can provide clues for certain genetic predispositions like lactose intolerance (e.g., MCM6 gene) or celiac disease (HLA-DQ2/DQ8), but they are not a universal solution for abdominal pain. Most causes – irritable bowel syndrome, infections, non-genetic food intolerances, stress, or organic diseases – are not captured by such tests. The evidence for the benefit of genetic testing in non-specific abdominal pain is weak; predictive power is low and many variants are ancestry-dependent. Moreover, results can cause unnecessary worry or lead to restrictive diets without medical supervision. Clinical evaluation (history, physical exam, stool tests) remains the gold standard. A DNA test may be useful as an adjunct when a specific genetic component is suspected, but not as a standalone diagnostic tool. Beware of exaggerated marketing claims: most gut issues are multifactorial and not genetically determined.
