DISTRAUGHT Katie Price has said her son needs to lose weight, or he will die.

The former glamour model, who lives in Sussex, has told of her desperation after son Harvey's weight reached nearly 29st.

Disabled Harvey, now 18, has a condition called Prader-Willi syndrome which makes him crave food.

Katie has been told by doctors that he is at serious risk of a heart attack if he does not lose some of the weight imminently.

Mum-of-five Kate, 42, told The Sun: “He’ll need to lose weight or he’ll end up dead. I don’t want to lose him.”

Harvey has put on almost two stone in two months and is now 28st 7lb.

Katie said the situation is so bad that she was recently forced to beg fans for help in finding a treadmill and rowing machine.

The battle to keep Harvey alive is “critical”, Price said, as he could drop dead from a heart attack.

She keeps a padlock the family fridge and also has to lock the cupboards in the kitchen.

She told The Sun: “It’s a cruel illness. He feels hungry all the time.

“Every time I feed him, it’s killing him.

The Argus:

“Even though it makes him happy, it’s cruel of me to do it.

“He needs to lose weight or he’ll end up dead. He doesn’t deserve that. I don’t want to lose him.

“He’s only 18, he’s got his whole life ahead of him. I will do anything to help.”

Harvey turns violent when he doesn’t get what he wants, Katie said.

She said: “It’s a cruel and horrible illness where he feels hungry all the time — and if he doesn’t get food he gets angry. It’s hard work.

“He’ll smash things up if you say no. I’ve had to re-plaster my walls because he’ll bash holes in them with his head.

“He knows what nice things taste of. I’ll give him sweet potato chips instead of real fries but he knows the difference.

“It’s not what he eats in the day, it’s what he eats when I don’t see him. I’ve tried hiding food but he’ll find it.

“You can’t leave food or leftovers on the side or he’ll eat it, and he’s really quick too.

“He even eats in his sleep. He’ll walk downstairs and eat whatever he can find.

“We’ve even found him rummaging through friends’ bags for food.”
