Perez had IV treatment after qualifying
Sergio Perez was rehydrated with the help of an IV drip after qualifying in Malaysia.
The Mexican told the media he has been suffering from a stomach virus.
"This is possibly the worst place to not feel 100 per cent," said the Force India driver.
As they spoke with the 27-year-old, reporters noticed that Perez had a 'band-aid' plaster on the inside of his forearm.
He confirmed: "I had to replace all the fluid that I have lost in this way.
"I suffered a lot in qualifying and this is the hardest race on the whole calendar, so it will be difficult for me."
