People can gain with hyperthyroid problems also. Believe me I know. I am hyperthyroid from graves disease and i have gained 60+ pounds from being hyper. Why?? Being hyper does increase all activity in the body.......... including appetite. I eat and 30 minutes later i am starving again. not just hungry, but starving!!!!
