Katie Price's son Harvey is set to start taking weight loss jabs

Katie told The Sun newspaper: "He's at risk of a heart attack, and because of his condition, he's not getting any smaller. He's putting on weight. It doesn't matter what we do.

"He can't put his shoes on without sweating. He can't walk far because he gets out of breath.

"It's because of all the weight. So the doctors are doing it to give him a better, longer life, and for his health."

Harvey is also blind and autistic, as well as having septo-optic dysplasia.

Although Harvey is an adult, he's still being treated at London's Great Ormond Street Hospital for children.

Former glamour model Katie explained that the weight loss drug won't impact his other medication, and it can be stopped quickly if there are any side effects.

She said: "The good thing about starting him on the drug is, if it has any effect, you can stop it because you do it weekly.

"We've tried food, he's had ¬dietitians, it's just the way he is. And he's on a lot of medication which the drug won't affect.

"They want to try him on it for at least one or two years, which is a long time, but they'll control what level he needs then up it as they assess it."

Katie previously revealed she was shocked by the treatment she allegedly received from a GP when Harvey was first diagnosed as blind when he was just a few weeks old.

Appearing on the 'Anything Goes' podcast with James English, she recalled: "I remember sitting there with my mum and [the doctor] was getting all his stuff out looking in his eyes and then suddenly just went, as blatant as this, 'Yeah he's blind, yeah he's blind'.

"And me and my mum looked at each other and were like what, 'Is he definitely blind?' And [the doctor] went 'yeah he's blind' and we were like, 'right'.

"He goes, 'Yeah, so sorry about that' and we just sat there like right. And that was it.

"We just left the room, no like, 'Oh we can give you advice' or 'there's these people you want to talk to.' "
