President Nicolas Sarkozy is "doing well" after being flown to hospital with a "minor" nerve complaint on Sunday.
The French leader was taken ill while jogging during a humid afternoon at his weekend retreat at the Chateau of Versailles, outside Paris.
He was flown to the Val de Grace hospital by helicopter, where he was later joined by wife Carla Bruni-Sarkozy.
The 54-year-old remained in hospital overnight for "routine tests," officials have revealed.
French member of parliament Patrick Balkany has blamed the problem on a diet he said the president was following to lose weight.
"The president is going to have to take more care, work a little less hard and eat a little bit more," he said.
It is believed Nicolas - a keen runner and cyclist - will continue with official engagements on Tuesday.
