My t3 (liothyronine) is low' but tsh and t4 are normal levels. i was told not to worry about it unless i show signs of hypothyroidism what are signs of hypothyroidism

More complicated...: There are many signs and symptoms of hypothyroidism, including fatigue, weight gain, constipation, cold intolerance, depression & more. Total T3 (liothyronine) changes with time in the menstrual cycle & as one enters menopause. FT3 (liothyronine) is better lab, but labs not as accurate as for FT4/T4. T3 (liothyronine) & Free T3 (liothyronine) can go down with other illness you have like depression & asthma if sig. Replacement is not rec & controversial.
