The 67-year-old former medical doctor is known for appearing on television programmes like This Morning and The One Show, and presenting Trust Me I’m a Doctor on BBC Two.
Senior Greek police spokesperson Constantina Dimoglidou confirmed searches for the star began early on Thursday morning, with no trace yet found.
He went missing after he set off hiking along St Nicholas Beach on Wednesday lunchtime.
“He was at the beach of Ag. Nikolas with another couple when he decided to go back to his home in the area of Pedi of Symi,” the spokesperson said.
“It was around 1.30pm and he forgot his phone at the beach. Any and every attempt to track him down has not produced any result.”
She added that emergency services were exploring “every potential scenario”.

“We have now asked the fire brigade to assist in the operation in the case that he may have slipped, tripped, fallen, even bitten by a snake, remaining injured somewhere,” Ms Dimoglidou said.
“There is just no trace of him. None whatsoever and that means that for us at least, every potential scenario is open and being investigated.”
Dr Mosley’s wife, Dr Claire Bailey Mosley, reportedly raised the alarm when he failed to return from the hike.
The appeal read: “A search and rescue team is coming from Athens with drones and other more sophisticated equipment to extend the search.
“They are expected to arrive by about 1 p.m.”
