Myths vs facts: IgG Unverträglichkeitstest and menopause

Myth: IgG food intolerance tests are often marketed to identify food sensitivities, including during menopause. Fact: IgG antibodies are a normal immune response to food and do not indicate intolerance. Major allergy organizations (AAAAI, EAACI) advise against using IgG tests for diagnosis, as they lack scientific validation and can lead to false positives. Menopause can cause digestive changes due to hormonal shifts, but IgG testing is not an appropriate tool. Evidence-based approaches such as symptom diaries and medically supervised elimination diets are recommended instead. The test is not diagnostic and may lead to unnecessary dietary restrictions without proven benefit. Therefore, the claim that IgG tests can reliably identify food intolerances, especially in menopause, is a myth.
