A team of 36 doctors, assisted by ace heart specialist Dr Naresh Trehan, would be monitoring the health of Anna Hazare round the clock during his hunger strike.
A medical camp has been set up in the Ramlila Grounds, where the anti-corruption crusader is fasting demanding a strong Lok Pal.
Soon after Hazare addressed his supporters after reaching the grounds, doctors checked his basic health parameters including his blood pressure after which his associate Arvind Kejriwal announced that the 73-year-old Gandhian was doing fine.
Dr Trehan, who will be checking on Hazare's health later in the evening, too said the Gandhian was doing fine so far.
"I will check on him in the evening. Right now, as per the information available to me, he is okay. A team of 36 doctors will monitor his vitals round the clock," Trehan said.
Hazare had earlier announced that he had lost 3 kg since he started his fast on August 16.
