When asking about stomach and digestion, it's important to understand that digestive issues like bloating, heartburn, or fullness are often multifactorial – diet, stress, gut microbiome, food intolerances, or impaired stomach acid production can all play a role. DNA tests (e.g., for lactose intolerance or celiac risk) can provide genetic clues but are not diagnostic on their own. Blood tests measuring IgG antibodies to foods are widely marketed but lack strong clinical evidence; many medical societies advise against using them for food intolerance diagnosis. A gut microbiome test can reveal bacterial composition, but its direct link to symptoms is still debated. For persistent symptoms, a gastroenterologist should be consulted. MyBody-X offers intolerance and microbiome tests that can serve as a starting point, but they are not a substitute for medical evaluation. Evidence: Genetic testing for lactose intolerance is well-supported; IgG food sensitivity tests have weak evidence. Overall, the evidence is mixed.
