His remarks came after yoga guru Ramdev levelled allegations that Hazare's condition was not improving because of the wrong medicines administered to him.

Team Anna sources on Sunday had also alleged he was administered an overdose of antibiotics and steroids during his treatment.

Hazare flew down to Delhi from Pune on the same day and left straight for Medanta Medicity where he underwent a series of medical tests.

The 74-year-old activist was treated for acute bronchitis at a hospital in Mumbai earlier this month after he called off his hunger strike for a strong Lokpal Bill midway. He was discharged on January 8.

Defending Dr Kanti Lal Sancheti, who treated him after his fast in December, Hazare said he knew the physician for the last 25 years and that he did not believe the allegations.

"It is being said that I was given an overdose of medicines and that some (medicines) were not needed. I don't think that I was given medicines with malafide intentions. Maybe my body cannot accept these medicines," he said in a statement.

Noting that Dr Sancheti was a Padma Vibhushan awardee, he said it was wrong to link it with his health. "He was awarded for his services for 40 years. I congratulate him," Hazare said.
