What to watch with FT3 and Haut?

When looking at FT3 (free triiodothyronine) and skin, the connection is clinically plausible but not well-defined in the provided context. Thyroid hormones regulate skin cell turnover, sebum production, and hydration. Low FT3 can contribute to dry, rough skin, poor wound healing, and hair thinning. High FT3 (as in hyperthyroidism) may cause warm, moist skin, flushing, or itching. However, FT3 alone is not a reliable skin marker; full thyroid panel (TSH, fT4, antibodies) and dermatological assessment are needed. The available context lacks direct evidence linking FT3 to specific skin conditions. Evidence grade: unclear. Caveat: Do not self-diagnose or adjust thyroid medication based solely on FT3 and skin symptoms. Consult a physician for proper evaluation.
