many conditions besides thyroid issues can contribute to weight loss. because your tsh levels are within the normal range your weight loss falls into the "unexplained" category. this is always concerning. i'd suggest you see a health care provider to find out what's going on. if you're actively trying to gain weight but continue to lose instead you need to get to the root of the problem. best wishes to you!
