Does anyone know if it is common for Hughes suffers to have thyroid problems? Since being diognosed in may I've put on 3 stone! I've been doing better and I'm loads more active and have put on another half a stone. I'm a healthy eater who likes the odd naughty like anyone else. My diet hasn't changed only my mobility which has been on the increase for the last 6 weeks! I no long drink alcohol so not got those extra calories! what is going on? Has this happened to anyone else? Is it the drugs? I'm on warfarin, beta blocker as have AF as well. It would be nice to hear from others. My doc has said he will do a blood test but after reading thyroid ass web site they say GP's are not good at diognoising the condition!! Help!!!
