Katie Price's disabled son Harvey is back in hospital again tonight after complaining of being unable to breathe.

The 18-year-old, who suffers from Prader-Willi syndrome, autism and partial blindness, was hospitalised a fortnight ago due to chest pains - with doctors subsequently diagnosing a chest infection.

According to The Sun, Price called the emergency services on Sunday after Harvey's temperature shot up to 42 degrees and he began experiencing breathing difficulties.

"His condition is very dangerous and Katie is terrified," a representative told the newspaper. "One of his conditions is adrenal failure that could cause his organs to fail and is very dangerous."

Price recently revealed that doctors have advised her that Harvey's weight - some 27 and a half stone - needs to be cut down significantly or he will face more serious health consequences.
