I've had thyroid cancer and gained 4 stone over the process. Although I didn't exactly gain any before my operation - I'd been in weightwatchers for 2 or 3 years before, unable to lose that last stone in weight.
I gained most of my weight during the periods when I was on zero thyroxine for RAI, gaining about a stone each time, over a period of a week.
I read the article yesterday, and found it really useful even now. Still being quite disabled after nearly 3 years, it's hard to figure out your place in the world. Sometimes I underestimate what being ill has been, and feel like it's a small thing - strangers nearly always enormously underestimate it. This article of course from being in the Daily Mail overdramatises everything. But it also gives the kind of response I think a lot of ordinary people would have, in terms of being shocked by fairly 'minor' symptoms like gaining weight. It gave me something to think about, and also something to show to friends if I think it's what they need to see. I will definitely print it out and keep it.
