I have many hot flushes per day but my temperature and pulse are normal. I increased my T3 from 5 to 10 mcg a few weeks ago and stayed at 150 mcg T4 as previous blood work suggested room for improvement in T3 (TSH: 0.12 (0.35-5.5); FT4: 15.9 (10-19.8); FT3: 4.1 (3.5-5.5), the latter done after leaving 36 hours before bloods, previous fT3 at 5 mcg T3 showed 4.7, same range).
However, my pulse and temperature are within my normal range (37.3 C on waking, 36.9 C at bedtime, pulse around 75-80 bpm. Occasionally higher, but only when I stand up (blasted POTS!). I've not had a blood test since the increase but will ask for one the next time my lithium serum levels are checked.
Are the hot flushes likely to be from the increase in T3 and a sign of overmedication? I'm also being investigated for early menopause so the hot flushes could be related to that.
