Surgeons vary but think hard. You need to be sure you have stopped and won't loose much more (or gain more) as its expensive to have done, once done it will "give' a little without any effect say a stone either way but put on you will stretch it and if you lose again it will be loose and flappy. If you lose more same thing. Most surgeons who really understand skin removal after major weight loss, not just due to surgery will ask that your weight has been stable for 1-2 years, some private have a BMI but most don't, stability is what they are concerned with. Really you should be too, its costs £5000+ for each op in the UK done separately (less if combined) do you really want to spend that and then loose/gain weight and ruin it? Full plastics can cost up to £30,000 my advice, having had it all done, is oh yes it is so worth it but be so careful. Yes of course you want it and it is natural to want it now but don't put your hard earned cash at risk for want of waiting a bit seeing where you are going. I only waited 2 years before I started and had lost 100% of my weight. I did loose more but that was due to problems, my skin bagged but since regaining back to normal weight its OK again. So many regain, often fairly quickly or think they are done but actually its just a delay. Take your time with plastics you will be glad you did!!
