Have hashimotos, gaining weight but my appetite has increased significantly, always trying to find something to eat to make me feel better. what is up?

Need evaluation: If the thyroid is adequately treated (tsh in normal range) then it could be something else. Eating to feel better can be a sign of depression. Sometimes other medications used for migraine, sleep, pain or inflammation can also increase appetite. Topamax (topiramate) reduces hunger, has the dose been reduced? And sometimes hunger can be a sign of menopause.
