Q: I am a 25 years old woman having hyperthyroidism for the last five months. I am taking Neomercazole, half tablet of Inderal 40 mg and Shelcal 500 thrice daily. Now my T3 and T4 are within the reference range but TSH is below the reference range so the doctor suggested half tablet of the Neomercazole thrice daily along with other medicines. Almost all the symptoms are presently under control but swelling in my eyes is still there. Will swelling be cured completely? Should I take the thyroid test every month? My weight is 47 kg. Will low TSH result in weight gain?

A:TSH may take months before it becomes normal during treatment of hyperthyroidism but you need to continue medications at least for a 12-18 months. I would suggest you reduce the dose to 10 mg twice daily. You can have T4 and TSH done every 6-8 weeks. Thyroid related eye disease can have variable course, in fact sometimes it occurs after treatment but in most cases there is a relief after medical therapy, which you are taking. Low TSH does not cause weight gain. You must be gaining weight now because you are getting normal. During state of hyperthyroidism one loses weight.
