Tammy Slaton has now reached her weight loss goal and been approved for surgery, with her sister Amy Slaton admitting she is "nervous" about Tammy going under the knife.
Tammy was checked into a food rehabilitation centre after struggling with her weight for years, but has since found out she has lost more than 180lb (12.9 stone).
After completing her rehab programme, Tammy is now preparing for bariatric surgery, but Amy said she was fearful that "anything could happen".
