I have been losing weight for about 7months went to my dr because I was having hot flashes, tired all the time, weight loss achy muscles hair shedding . She did all the test for the thyroid which the results came back I had hyperthyroid she put me on this medicine called methimazole 10mg twice daily. But doesn't seem like its working only symptoms I currently don't have is the hot flashes as bad as I use to but I'm still losing weight is there anything else I can do to control this constant weight loss.. I went from a 13/14 to now wearing a size 8 and that's a little big. I've done research but it seems all the answers are for the people who have hypo thyroid symptoms nothing for the hyper thyroid... Any information will be greatly appreciated...
