A 40-strong team of doctors, paramedics, fire crews, council workers and scaffolders worked Thursday to free 19-year-old Georgia Davis, who needed to go to the hospital after falling sick.
It took experts eight hours to remove a wall, leaving a 10-foot (3m) by 10-foot (3m) hole in the top floor of the townhouse in Aberdare, South Wales.
A bridge was built from the sidewalk to the gap in the wall to enable the emergency services to remove Davis, who was thought to have been conscious during the procedure.
The Welsh Ambulance Service sent a specially reinforced vehicle for obese patients — known as a “bariatric ambulance” — to the property.
A joint statement by the emergency services involved said that after visiting the house, the decision was made to “remove a female from the premises.”
“All agencies, including Rhondda Cynon Taf council’s emergency planning and social services team, returned along with a number of specialist teams from South Wales Fire and Rescue Service and a scaffolding company to secure the removal of an area of the premises,” the statement added.
In 2008, Davis — then 462 pounds (210kg) — was sent to a “fat camp” in the US to lose weight.
After nine months she had managed to reduce her weight to 252 pounds (114kg), but has since spoken publicly about her struggle to keep off the weight.
She once compared her desire for food to an addiction, “If you get to the point where I was, you can’t stop eating. It is like heroin — you need help. I really didn’t want to be that person anymore.”
