Myths vs facts: HLA-DQ2 and Wechseljahre

The claim that HLA-DQ2 directly affects menopause is a myth. HLA-DQ2 is a genetic risk factor for celiac disease, not for menopausal transition. However, some evidence suggests that untreated celiac disease may lead to earlier menopause and exacerbate symptoms like fatigue or bone loss. This does not mean the gene itself drives menopause. A DNA test for HLA-DQ2 alone is not diagnostic for menopausal issues. If a woman experiences persistent gastrointestinal symptoms, fatigue, or osteoporosis during menopause, screening for celiac disease (including HLA typing) may be warranted, but only as part of a full clinical workup. The evidence level is moderate: observational studies link celiac disease to altered menopause timing, but no direct causal role for HLA-DQ2 in menopause has been established. Be cautious of marketing claims that overstate the relevance of this genetic variant for menopausal health.
