Hi. I did thyroid profile test today, my TSH has come -15.76 . I have been taking thyronorm 100mcg daily without missing a dose. Checked thyroid profile three months back also it was normal. Recently i noticed weight gain, swelling in limbs, tiredness and my periods have been delayed (UPT is negative) so i thought of getting a thyroid profile done. There has been a lot of stress since one month because my exams are nearing. My sleep and eating Patten had changed, now i have taken care of those factors. Now pls guide me regarding the furtger steps. Should i be increasing the dose of medicine or continue the same dose? I will be repeating the test again next month.
