How are TSH and Haut related?

TSH (thyroid-stimulating hormone) is produced by the pituitary gland and controls the release of thyroid hormones T3 and T4, which directly affect skin health. In hypothyroidism (high TSH), common skin changes include dryness, roughness, scaling, reduced sebum production, and delayed wound healing. In hyperthyroidism (low TSH), the skin often becomes warm, moist, thin, and prone to flushing or excessive sweating. Hair loss and nail brittleness may also occur. This relationship is well-established in clinical endocrinology and dermatology, but it relies on blood hormone levels, not genetic testing. A DNA test cannot measure TSH; a blood draw is required. If MyBody-X offers a biomarker panel that includes TSH, the result can be interpreted in the context of thyroid function and skin symptoms. Evidence is strong (human studies, textbooks), but individual skin responses vary. Caveat: skin issues have many causes; elevated TSH alone does not explain every skin problem. Medical evaluation is recommended for any persistent changes.
