warum sieht mein bauch aus wie schwanger — can a DNA test help?

A belly that looks pregnant can result from bloating due to food intolerances (lactose, fructose, gluten), irritable bowel syndrome, small intestinal bacterial overgrowth (SIBO), hormonal changes, or simply swallowing air. A DNA test can identify genetic variants linked to some of these conditions – for example, lactase persistence (LCT gene), celiac disease risk (HLA-DQ), or variants in MTHFR (folate metabolism) and GSTM1 (detoxification) that have been weakly associated with digestive issues. However, the evidence is moderate at best. Bloating is multifactorial; diet, gut microbiome, and lifestyle matter far more than single genes. A DNA test cannot diagnose the cause of a distended abdomen. If you consistently have a 'pregnancy belly,' consult a doctor to rule out organic causes like celiac disease, ovarian cysts, or other medical conditions. Genetic testing may offer clues but is not a substitute for clinical evaluation. Most marketed 'bloating genes' have only mechanistic or observational support, not strong clinical validation.
