Evidence check: IgG in the context of menopause

IgG antibody testing for foods is commonly marketed as a food intolerance test, but it is not scientifically validated as a reliable marker for intolerances or menopausal symptoms. During menopause, hormonal fluctuations can cause non-specific complaints such as bloating, fatigue, or joint pain. IgG tests merely reflect immune exposure and yield frequent false positives, even in healthy individuals. There is no robust evidence linking IgG levels to menopause-related symptoms; clinical studies do not support its diagnostic utility. MyBody-X itself rates the evidence as 'marketing/unclear'. Caveat: These tests should not replace medical evaluation. For menopausal symptoms, hormone status, thyroid function, and other organic causes should be assessed by a physician. IgG-based elimination diets may lead to unnecessary restrictions and nutrient deficiencies.
