However, the scientific consensus is clear: IgG antibodies to foods are a normal physiological response to food exposure and do not reliably indicate intolerance or allergy. Multiple allergy and immunology societies (e.g., AAAAI, EAACI) advise against using IgG tests for diagnosis. The evidence linking IgG test results to fatigue is weak and largely based on anecdotal reports or poorly controlled studies. Fatigue is multifactorial – common causes include sleep disorders, stress, nutritional deficiencies, thyroid issues, and chronic diseases. Relying on an IgG test may lead to unnecessary dietary restrictions without addressing the real underlying problem. Evidence level: marketing/mixed. Caveat: some individuals may feel better after an elimination diet, but this does not validate the test. Always consult a healthcare professional for persistent fatigue.","area":"gesundheit","canonical_id":"gesundheit:canonical-660262e3a38cde3844c9a7b4","id":"public-4dfde182f982204ed6a41f84","kind":"qa","language":"en","publication_status":"existing_native_answer_privacy_screened_sources_pending","question":"Myths vs facts: IgG Unverträglichkeitstest and fatigue","score":37.63657906,"snippet":"IgG food intolerance tests are often marketed as a way to identify foods that cause chronic fatigue.
