I began to suffer from hyperthyroidism and my body was thin. After eating methimazole tablets and propranolol hydrochloride tablets for a while, I began to gain a lot of weight, and my stomach was too fat to see anyone. Why? It has little to do with drugs. One of these two drugs inhibits the thyroid gland and the other controls the heart rate. It is not a hormone and will not produce obesity. It could be hyperthyroidism. Okay, you ate too much. Generally speaking, if the illness time is short, it should not be centripetal obesity.
