World's fattest child - who weighs 31st at 10 years old - set to undergo weight ...

The fattest child in the world who weighs a whopping 31 stone at just 10 years old will undergo weight loss surgery in a bid to save his life.

Mohammed Arbrar, from Pakistan, struggles to stand after regularly scoffing meals meant to feed four adults.

Despite weighing just 8lb at birth, he began gaining weight rapidly - tipping the scales at three stone when he was just six months old.

His doctors say he is the fattest boy in the world, weighing even more than Indonesian Arya Permana, who hit the headlines for weighing 29 stone aged 10 three years ago.

His parents, who have two other healthy children, said Mohammed was perpetually hungry as an infant and would drink five times as much milk as his elder siblings.

He was so heavy that his mother Zareena could not change his nappies alone and had to get a specially-made bed to take his weight.

She said: 'He weighed eight pounds at birth but his weight never stopped growing.

'He used to drink two litres of milk when he was only two years old. It was like his stomach never filled up. He always cried for more food.

'It was very difficult for me to even carry him. We had to make a special swing and a bed for him to change nappies.'

With his massive frame, even basic activities like walking and sitting are an uphill task for the pre-teen boy.

Despite having three siblings, Mohammed cannot play with them as he cannot take more than three steps at a time
