Katie Price is worried her son Harvey is close to having near-fatal diabetes.

The 38-year-old TV personality said that her 14-year-old son - who she shares with former lover Dwight Yorke - weighs 18 stone due to his rare genetic condition Prader-Willi syndrome, which makes sufferers always feel hungry.

She said: ''He's 14, he weighs 18 stone. He never knows when he's full up - he'll do anything he can to feed himself. At the table you'd think he'd never eaten.

''He's that close to getting diabetes at the minute. He's still got a kid's heart it would be fatal if we don't watch him.''

The former model said that she constantly battles with the choices of food to give her son, and admitted to giving in to his hunger with treats.

Speaking on ITV's 'Loose Women' on Thursday (15.12.16), Katie said: ''We do have lots of food in our house, we're not health conscious. When I go food shopping, to get Harvey around he wants a blueberry muffin but they only sell them as a four so he has to walk around with four muffins.''

And although she is concerned for the health of her oldest son - who also suffers from autism, ADHD and blindness - Katie thinks it has taught her other children, particularly her 11-year-old son Junior - who she shares with her former husband Peter Andre - how to stay healthy.

She added: ''The good thing about it, if there is a good thing, it is the other kids are aware of what it's like to be overweight.

''With my other children if I thought they got bigger I'd notice it. Junior is obsessed with having a six pack ... because his dad was famous for it.''
