Last September, bloodtest showed my TSH was 13. My doctor started me on synthroid and got my levels in the normal range a few months ago at 75mcg.

When I got the 13 TSH reading, I was taking some OTC diet pills, trying to lose weight. I NEVER had any hypothyroid symptoms until I started taking the meds. Now, I have gained 15lbs that I cannot lose, am exhausted all the time, angry and crabby and don't break out in welts.

Could the diet pills I was taking have raised my TSH? I am considering quitting the synthroid as I go back in about 4 weeks for more bloodwork just to see how I feel and to see what my TSH will be w/o the meds.

It's just odd to me that I didn't seem to have any symptoms until I started the meds. It's SO frustrating.
