The Who Wants To Be A Millionaire host was rushed from Heathrow Airport to hospital in West London after falling ill on a plane from Bangkok.
Tarrant spent a week recovering in hospital after doctors discovered he had a potentially fatal blood clot in his leg.
Medical staff had initially thought he had suffered an asthma attack while on board the plane.
His agent, Paul Vaughan, told The Sun newspaper: "The doctor describes it as a mini stroke, probably brought on by the asthma and bronchitis on the plane. They found a clot which they managed to break up."
Tarrant had been filming in Asia and South America before falling ill and Mr Vaughan said he would not be going straight back to work after he is discharged.
He said: "He is determined to leave hospital. But he's not going back to work. This is a nasty wake-up call."
