Hyperthyroidism and Weight Gain. .?

mayb ethe carbimazole is too much for you and now you are hypothyroid. it's just a guess. and because you are not hyperthyroid anymore it is causing you to gain weight. SO have your TSH and Free t4 checked so that your doc adjusts your dose and take less carbimazole. then you ll start losing weight when back to normal. good luck!!!!!!!
