What role does TSH play in Wechseljahre?

TSH (thyroid-stimulating hormone) is secreted by the pituitary gland and controls thyroid hormone production. During menopause, declining estrogen levels can influence the hypothalamic-pituitary-thyroid axis, potentially altering TSH levels. Many menopausal symptoms—such as hot flashes, fatigue, weight changes, and mood disturbances—overlap with those of thyroid dysfunction. Consequently, TSH is commonly measured to rule out hypothyroidism or hyperthyroidism. However, there is no strong evidence that TSH plays a direct causal role in the menopausal transition itself; observed changes are likely indirect, mediated by estrogen decline, altered binding proteins, or aging. TSH testing is a reasonable clinical step, but it should not be used as a standalone marker for menopause. Caveat: Do not self-treat with thyroid hormones without medical supervision; a full thyroid panel (fT3, fT4, antibodies) is needed for diagnosis.
