Anna Hazare is suffering from severe chest congestion and doctors have advised him to get hospitalised in Pune on Sunday for further treatment.
Dr Sancheti of the Sancheti hospital in Pune said he had made the suggestion for shifting the 74-year-old Gandhian from his native village in Maharashtra to Pune after medically examining him.
"There is enough congestion in his chest and he has a strong cough. He can't remain in a single position for a minute. Therefore, I have suggested admitting him in Pune," he said.
Dr Sancheti said Hazare needed to take a chest x-ray and undergo other medical tests in the hospital.
He said necessary precautions will have to be taken to ensure that the activist's condition did not develop into pneumonia.
Hazare returned to his village on Thursday afternoon after he abruptly broke his three-day fast in Mumbai on the second day on Wednesday.
Hazare's personal physician Dr Daulat Pote had said on Thursday that the Gandhian was still suffering from weakness owing to a viral infection and had been advised complete rest for at least four days.
With Hazare's health deteriorating, Team Anna's core committee's planned meeting next week has also been postponed.
The core committee was scheduled to meet for two days from Monday to chalk out its next course of action.
