William McBride has become the youngest person in the world to have stomach-shrinking surgery after he went through the procedure at the tender age of 10.
McBride, now 12-year-old, was so overweight that he could barely walk and was told he'd end up in an early grave.
However, two years ago, he had weight-loss surgery to tackle his 14-stone bulk and within a year he was five stone lighter.
McBride, who is now just over eight stone, says the operation has transformed his life.
"I just feel so good and I don't have to spend my days in a wheelchair. I can still eat what I want, but I'm no longer hungry all the time," the Mirror quoted McBride as saying.
"My life has changed so much. I can walk wherever I want to go and just feel so much better," he added.
