On Sunday evening, Price shared a tweet informing her 1.9m Twitter followers of her son’s condition.
Harvey, who was born in May 2002, has partial blindness, autism and Prader-Willi syndrome, a rare genetic condition that can cause physical issues and behavioural difficulties.
In her tweet, Price wrote: “I can confirm that Harvey is in intensive care and in the best hands.
“I would like to thank the ambulance services and the hospital staff for the quick response and making him stable.”
Price did not confirm why her son had been admitted to hospital.
Several people responded to Price’s tweet expressing their hope that her son gets better soon.
“Sending lots of love and prayers Harvey,” commented Geordie Shore star Nath Henry.
“Lots of love and prayers for a speedy recovery,” said actor Sally Phillips, while celebrity chef Rustie Lee added: “Sending best wishes and love to Harvey and you love.”
Harvey’s father is retired footballer Dwight Yorke, who Price dated in the early 2000s.

The former Loose Women panellist has five children in total, of which Harvey is the eldest.
The 42-year-old shares two children with ex-husband Peter Andre and two children with ex-spouse Kieran Hyler.
Earlier this month, Price announced an upcoming BBC film about her son Harvey which would see her “open up about what it’s really like to be a mum of a disabled child approaching adulthood”.
In June, the media personality gave evidence in a parliamentary inquiry about online abuse, speaking about the impact social media abuse has had on Harvey.
