Photos: Unable to walk out of her house for 6 years, Britain's fattest woman dies of heart attack

Britain's fattest woman who weighed 40st died of a heart attack aged 44 after being unable to walk out of her house for six years.

Doctors warned Brenda Flanagan-Davies to 'lose weight or die' when she became bed-bound at her home in Gateshead, Tyne and Wear, after consuming more than 6,000 calories a day.

But just four hours after a check-up in July 2013, where she returned home via an ambulance, her husband Ronald Davies found her foaming at the mouth and in pain.

He called an ambulance, and four paramedics used a blanket to carry Mrs Flanagan-Davies to the vehicle, but she died on her way to hospital after suffering a heart attack.

Mr Davies, 68, who had been with his wife for five years, now wants to warn people about the risks of obesity after he was left 'devastated' following her death.

The retired labourer and water inspector, said: 'She was alive one minute and dead the next.

'I think the heart attack was down to her weight and her health. It could have happened at any time.

'I don't know what to do. When I used to sit in the living room I would talk to her.

'I still find myself speaking to her in the other room since she died but obviously there is no answer as she's not there.

'I want to warn other people to look after after themselves and not to decline help if anyone wants to give you a hand.

'I wouldn't want what happened to Brenda to happen to other people.'

Since her death last year, Mr Davies has now changed his lifestyle and his diet.

He said: 'I have realised since Brenda's death that is is important to be healthy. Being healthy stands you in good stead as you get older. I feel much healthier now I am eating better.

'Brenda loved kebabs and sausages. We would get steak and kidney pies sent up from the butchers and fish and chips delivered.
