Is IgG Unverträglichkeitstest useful for menopause?

IgG food intolerance tests are marketed for identifying food sensitivities, but they lack scientific validation. IgG antibodies are a normal part of immune memory and do not reliably indicate intolerance. For menopause, there is no evidence that IgG testing is useful. Menopausal symptoms like hot flashes, mood changes, and weight gain are driven by hormonal shifts, not food allergies. Evidence-based approaches include hormone testing (e.g., estradiol, progesterone, FSH) and lifestyle modifications. MyBody-X offers hormone analysis, but results should be interpreted by a clinician. IgG tests can lead to unnecessary dietary restrictions without benefit. The evidence level is 'marketing' or 'unclear'. Caveat: Do not use IgG tests to guide menopause management.
