Is IgG useful for menopause?

IgG antibody testing is often marketed for food intolerance diagnostics, but its utility in menopause is not supported by scientific evidence. IgG against food proteins is a normal immune response and does not reliably indicate intolerance or disease. Professional guidelines (e.g., from the European Academy of Allergy and Clinical Immunology) explicitly advise against using IgG tests for food intolerance diagnosis. Menopausal symptoms are driven by hormonal decline (estrogen, progesterone) and are not linked to IgG-mediated mechanisms. There are no high-quality studies showing that IgG-guided dietary changes improve hot flashes, sleep disturbances, or mood changes during menopause. Relying on such tests may lead to unnecessary dietary restrictions and costs without benefit. Evidence-based management of menopause includes hormone therapy (when appropriate), lifestyle modifications (exercise, balanced diet, stress reduction), and, in some cases, phytoestrogens or non-hormonal medications. In summary, IgG testing is not useful for menopause and should not be recommended.
