###Human: I have hypothyroidism after taking medicines for hyperthyroidism. What is going on? ###Assistant: Hello. I just read your query and from what you have mentioned, it appears that you have Hashimoto’s thyroiditis. I would suggest that you have a wait and watch approach. I would recommend that you just keep checking your thyroid function test results every six weeks as of now. Then, once your TSH (thyroid-stimulating hormone) stabilizes, you can check every three months. Also, your TSH is not so high that you must take any treatment for it. So, my advice would be better to wait and watch. Since this is a phase of thyroid dysfunction, please be patient about your weight. Once your thyroid stabilizes, your weight gain will improve. Hope you find my advice beneficial. Good luck. For more information consult an endocrinologist online -->
