In the near future I will be having my 2nd colectomy, and in preparation I have decided to put on weight. Currently I am 13lbs (6kg) above my normal weight and I'm not sure whether it's the right thing to do before an operation. The last time I was operated on my weight plunged to 75-80 lbs and I don't want a repeat of this situation. Given my height I doubt anyone could tell I'd put on weight so that's not an issue, I'm just worried whether I've overdone it.
