Mom Katie called an ambulance for her older child, who has Prader-Willi syndrome, after presenting symptoms that needed special attention.
A representative for Katie told the Sun: “Harvey was taken to the local hospital for tests – he was not well yesterday and has had symptoms today that require urgent medical attention.
“Katie recognized the signs and knew when to call an ambulance.
“He should be released later today,” they added.
In addition to the rare genetic disorder, Prader-Willi syndrome, Harvey suffers from other health complications, including septo-optic dysplasia – which causes blindness and affects its growth. He is also autistic and has an underactive thyroid and diabetes.
In photos obtained by the Mail, Harvey is seen being taken from Katie’s home in Surrey on a stretcher by a face mask carrying paramedics.

Earlier on Monday, Katie went to Instagram to pay tribute to her daughter Princess on her 13th birthday.
Along with a video of happy family moments, the former glamor model wrote: “Happy birthday to my princess from the absolute world.
“My first little girl who becomes a teenager. She is literally me in EVERYONE. Words are not enough to describe how much I love you! ”
“She is now 13 and dying to have her own Instagram account, so here is @officialprincess_andre. “
Over the weekend, Harvey appeared on Katie’s Instagram page playing the keyboard while her siblings and mother sang Happy Birthday to younger brother Junior Andre.
Junior turned 15 June 13 just two weeks after Harvey celebrated his 18th birthday.
Although Harvey often spends time at Katie’s home, the mother of five made the heartbreaking decision to send her to live in a nursing home last year.
Katie said she finds it hard to cope with Harvey, who now returns home on weekends and school holidays.
She previously stated that she thought nursing homes were “evil” but felt that she had no choice.
In an emotional appearance on This Morning explaining her decision, Katie said, “He is now six feet two inches and 24 and is still growing and starting up.
“I love him so much, it’s my absolute life, but he’s working hard now.
“At his school, they intern there. It took me centuries to be convinced that this is the best place.
“At least when he’s in school he can do it Monday through Friday after school club, I can always go and put him in bed and have dinner with him. ”
” [It’s] Monday to Friday only. Every weekend and holidays, I will have it. ”
