Hi there, I've been overactive for some time now and initially didnt have any weight loss although now Ive lost abt 6lbs in a month, despite eating lots, bad skin, hair falling out, night sweats and constantly tired. So Dr has suggested a thyroidectomy but I am super concerned about gaining lots of weight. Ive never weighed more than 8 stone 7 and am currently just over 8 stone. How can I prevent the weight gain? Would T3 do this? Would I have to buy this privately myself?
