I was diagnosed with hyperthyroid due to Graves in October, put on PTU, 3x a day 50mg. In November Dr. increased PTU to 100mg 2x a day, I felt like crap,headaches, most recently tired and gained weight, in December he said continue on the same dosage. Yesterday I told him I am not happy with the amount of weight I have gained I have cut down on carbs and sugar and I still gain. So he looks at the lab results and said that the TSH and the T3 levels still show me as undertreated...but....T4 show me as overtreated. So what gives? I don't understand it. Anyway, we agreed that I would go back to the 50mg 3x a day, he asks me every time I go in when I want to have RAI. I am going away next week so said I wouldn't even consider it until after my trip. I also said I would like to wait and see if I go into remmission, the Dr. said 30% of people go into remmission but he doesn't think I will be one of them. What is with the conflicting lab results? How would a Dr. know if one person compared to another may go into remmission? Any ideas? Anyone!
