As Anna Hazare's fast spilled over to the 12th day, doctors today raised concerns over his health saying they are more worried as the Gandhian's blood pressure has dipped while heart beat has increased.

More doctors have been stationed at Ramlila Maidan to keep a watch on the health of the 74-year-old Gandhian, whose hunger strike for a strong Lokpal has crossed 260 hours.

Dr Naresh Trehan, whose team is examining Hazare during the fast, said "We have more concerns than last night. His blood pressure has decreased while heart beats have increased.

"The blood pressure was going steady but it has come down. We have taken blood samples. Due to his weight loss, there is energy loss also," he said.

He said since blood pressure has decreased, they have doubled the number of doctors at the Maidan to attend to him.

Team Anna sources said doctors were really worried and they fear that his internal organs have started getting affected due to the fast.

Hazare has lost more than seven kgs since August 16 when he sat on a hunger strike for a strong Lokpal Bill.

Last night, Trehan said, "There are concerns though his blood pressure and heart beat are okay. He has been asked to take more rest and not to strain himself."

Anna to continue protest for strong anti-corruption law

(PTI) Ahead of the debate on Lokpal issue in Parliament, fasting Anna Hazare today broke his silence of nearly 38 hours and addressed his supporters declaring that he will continue his protest till his last breath for a strong anti-corruption law.

Amid mounting worries over the 74-year-old Gandhian's health, Hazare said he could fast for another "three-four days" and "nothing will happen to him".

Hazare, who did not address his supporters since 8 pm on August 25, emerged on the dais at around 10 am to a loud cheer from supporters who raised slogans of 'Bharat Mata ki Jai', 'Vande Mataram' and 'Inquilab Zindabad'.

"I am not doing this for my personal gain. If it was so, I would not have lasted five days. Till Jan Lokpal Bill is passed, my protest will continue," the Gandhian told his supporters at Ramlila Maidan where he is sitting on a fast.

He said he was getting energy from those who are coming out in support of the cause and this energy will help him sustain for three-four more days. "Till Jan Lokpal Bill is passed, I won't die," he said in his speech that lasted for five minutes.

Hazare said he was surprised at the manner in which the country has responded to his call while referring to a person who was sporting a tattoo on his shoulder that stated that he was the supporter of the Gandhian.

"I am surprised that a 'fakir' is getting this support. It is not me who is doing all this. God has pointed fingers at me. He has chosen me to do the work. It is he who is doing all this. I am praised for what I am doing. A 'fakir' should not be praised so much," he said.
