I agree with gimel that it would help immensely if you could post your latest results, along with the lab's reference ranges; these are lab specific, so must come from your own lab report. Always make sure you get a copy for your records, of every lab report.
That said, what "problem/disease" were you diagnosed with? Were you prescribed any med? If so, what type/ dosage?
Members can best respond if you will please post whatever thyroid test results and associated reference ranges you have. If you don't have the info, I suggest that you do so. You should always get a copy from the doctor and make notes on it regarding how you were feeling at the time and what meds you were taking. That way you will have good info for future reference. How much synthroid do you take daily?
