I am on 40mg Beta Blockers, between 1 to 3 a day, due to hyperthyroidism. I am currently waiting for the appointment at the hospital and they are meant to keep me going until then. I have looked at the official list of side effects and there is nothing about weight gain, but there seems to be a lot anecdotally.
I don't the hyperthyroidism has made me lost lots of weight as I have lost a stone and a half since May and I presume that it would be faster if it was due to hyperthyroidism. I have hugely reduced my alcohol consumption, and I think that is what has done it (I eat well and also walk over 50 miles a week.) Hence, I will be pretty fucked off if these bloody tablets are going to make me put it back on again!
