Can thyroid problems cause vaginal dryness?
Yes, thyroid problems—especially underactive thyroid (hypothyroidism)—can cause vaginal dryness by disrupting hormone balance and affecting mucosal tissue health.
Detailed Medical Explanation
Thyroid hormones play a role in regulating menstrual cycles and maintaining the health of mucous membranes, including the vaginal lining. Hypothyroidism can reduce oestrogen production, leading to dryness, irregular periods, and other symptoms. Blood tests (TSH, T4) help diagnose thyroid conditions, and treatment can improve symptoms over time. NHS: Hypothyroidism Symptoms.
Clinical Context
Women presenting with unexplained vaginal dryness should have thyroid function checked. Addressing thyroid imbalance can relieve dryness and improve overall health.
Evidence-Based Approaches
Clinical guidelines recommend thyroid assessment in women with persistent dryness and other hormonal symptoms. Treating the underlying thyroid disorder improves vaginal and systemic health. RCOG: Hormonal Causes of Vaginal Dryness.
