Anna Hazare's health became a serious cause of concern on Monday as his fast entered the seventh day, adding to the worries of the Manmohan Singh government which seems to be groping to find a solution to the standoff over the Lokpal bill.

Hazare's weight is down to 67 kg from 72 kg, he has lost five kg in seven days, his blood pressure is 130/80 and pulse rate 90, according to the health bulletin issued by his doctors. The longest he has fasted until now is for 12 days.

Cardiologist Dr Naresh Trehan, who is leading the team monitoring Anna Hazare's health, on Monday said, "His condition is not life-threatening is what I can say." But there is a rise in ketone levels, the presence of certain acids and acetone in blood and urine, which means the body is breaking down stored fat instead of the usual glucose.

Dr Anoop Misra of Fortis Hospital told TOI, "The patient has already entered the danger zone. He will need medical attention within the next 24-48 hours. The fast may affect the heart, kidney and blood pressure depending on how fast Anna's ketone level rises."
While Hazare does not yet require hospitalization, his failing health complicates the Centre's political risk as any mishap will prove catastrophic for the Manmohan Singh government.

Despite increased water intake, the 74-year-old Gandhian's health condition is deteriorating and he is very weak. He has discontinued morning yoga and has been advised to speak less.
