My TSH is currently .92 and I am on 75 mcg of synthroid. My OBGYN increased the dose to 100 mcg. MY TSH was 1.60 about 3 months and dropped to .92. I exercise a lot and still can not drop a pound and feel awful everyday. Is it ok to increase from 75 mcg to 100 mcg if my TSH level is .92 or is that too much Synthroid?
