A teenager weighing 63st was taken to hospital yesterday with the help of builders, scaffolders and members of all three emergency services.
Georgia Davis, 19, needed urgent medical care but it took around 30 people almost eight hours to get her into an ambulance.
The road outside her home was closed off as two walls of the house were demolished to move her from her first-floor bedroom.
A 10ft by 10ft space was cut into to the top floor of the house in Aberdare, South Wales, so that the emergency services could remove 19-year-old Georgia Davis

Rescued: Georgia, 19, from Aberdare, South Wales, is Britain's fattest teenager weighing around 63 stone
Large dust sheets and tarpaulins were put up outside her home in Aberdare, South Wales, so the operation could be conducted in private. 'This is not a freak show,' said a police officer.
Builders had to remove a window before tearing down an external and internal wall to free Miss Davis from her semi-detached council house.
Scaffolding and a makeshift bridge were used to move her safely, and while there was a crane on site, it is not thought it was used to lift her.
Residents said the operation to move Miss Davis began just after 9am, and she was seen leaving the scene in an ambulance just after 5pm.
The cost of the operation – involving police, fire service and ambulance crews – is likely to run into tens of thousands of pounds to cover manpower, plus the emergency call-out and the reconstruction of the demolished walls.

A neighbour said: 'It is a major operation and there's loads of people here just to get Georgia out of the house.
'She's too big to get out herself and they've had to take the walls down. It is tragic for her. She's done all sorts to lose weight with fat camps in the States and a thousand diets.
A bridge was also built from the roadside to the top floor with between 30 to 40 people involved in the operation

A few days ago Miss Davis wrote on her Facebook page: 'I'm in bed but problem is can't get up.'
She continued: 'Earlier I was blocked in the toilet for like 20 minutes and if you sit on the loo for that long it bloody hurts. My legs hurt and so do my back though my knees will give out if I stay seated any longer.'

After large dust sheets and tarpaulins were put up in order to hide what was happening, a police officer said: 'We want to keep people away. This is not a freak show.'
Miss Davis was declared Britain's largest teenager when it was revealed in August 2008 that she weighed 33st at just 15.
Doctors said she would die if she didn't lose weight and she was sent to an American fat camp where she shed half her body weight.
But after returning to the UK the 5ft 6ins teen ballooned after returning to her bad habits and gaining 16 stone.
Neighbours said she is thought to now weigh 63 stone, but added that it is impossible to know her true weight as it would require an industrial strength scale to measure.

Early signs: Georgia was an overweight toddler, and the rapid growth has continued to this dayEarlier this year Miss Davis's mother, Lesley Davis, who herself weighs 18st, said of her daughter's condition: 'I feel guilty, of course I do.
'Georgia now has trouble walking. When we walk along together, she gets out of breath after a few steps. It worries me sick.' But her mother said Georgia is unwilling to face up to her problem and spends her days sitting in her room chatting to her friends on social networking sites.
She added that promised help from the NHS - from free gym membership to a personal trainer - had not materialised.
'I know I'm probably eating myself to death again but at the moment I can't face up to it.'Miss Davis Georgia admitted her weight gain depresses her so much that she responds by eating even more.
The 5ft 6in teenager said: 'I try not to think about it too much, otherwise I panic and it makes my eating problem worse - but I do know it's serious.' She 'Of course people stare, but I don't care what they think any more - I'm used to it,' she told the Sun.
Just a few years ago, the outlook was far brighter for the teenager.
In August 2008, a 33st Georgia was told by doctors to 'lose 20 stones or die'.
Spurred into action, Georgia attended a £3,600-a-month Wellspring diet academy in the US for nine months, during which time she shrank to 18st and beat her Type 2 diabetes.
She was seen by behavioural coaches, food psychologists and fitness trainers and encouraged to walk 10,000 steps every day.
She returned to the UK in June 2009 to look after her mother who has a heart condition.
But she reverted to old habits when she returned home.
'When I arrived my mum said she hadn't had time to prepare any healthy food so we had fish and chips instead,' she said.
'For that moment on, I had a niggling feeling that things weren't going to work out.' At her slimmest, Miss Davis had a normal life expectancy of 80 years, but at her current weight she is not expected to live past 20.
She has said she wants more help from the NHS, insisting her problem is no different from drug or alcohol addiction.
