What to watch with IgG and menopause?

When considering IgG testing during menopause, it's important to separate marketing from evidence. IgG tests are often promoted for food sensitivity detection, but their clinical validity is limited. Menopause involves declining estrogen, which can affect gut barrier function and immune responses. Some research suggests that IgG levels against certain foods may increase during this period, but this does not necessarily indicate intolerance or disease. IgG reflects immune exposure, not necessarily adverse reactions. Instead of relying on IgG panels, women in menopause should focus on validated biomarkers like hs-CRP for inflammation, HbA1c for glucose metabolism, and vitamin D status. A balanced diet rich in phytoestrogens, fiber, and omega-3s, along with regular exercise, supports hormonal and immune health. Be cautious: IgG testing can lead to unnecessary dietary restrictions and anxiety. Evidence for clinical utility is weak; prioritize evidence-based assessments.
