When with your doctor make sure you discuss post weight loss options as well- I know people who've had skin removal once they maintained for a year and as you didn't go for weight loss surgery you should be entitled to something if you need it?
I am hoping I won't have much skin to remove with me exercising as much as I am, but my dad has said that he would pay for anything I need privately afterwards if the NHS decline, I should hope they wouldn't give the amount of National Insurance ive paid in over the last 14 years, I pay nearly 200 monthly lol.
