What to watch with FT3 and menopause?

Monitoring FT3 (free triiodothyronine) during menopause is relevant because thyroid function can be affected by hormonal shifts. However, the provided context does not contain direct studies on FT3 and menopause. In general, FT3 levels may fluctuate during perimenopause, often accompanied by symptoms like fatigue, weight gain, or mood changes. Low FT3 can indicate hypothyroidism, which may be exacerbated by declining estrogen. It is important to also measure TSH, fT4, and thyroid antibodies (TPO, Tg) to rule out Hashimoto's thyroiditis. Evidence is based on observational studies; causal links are not firmly established. Consult a physician before taking supplements like iodine or selenium. Caveat: No self-medication; potential interactions with hormone replacement therapy.
