As Anna Hazare's fast entered the 11th day on Friday, the Gandhian lost seven kg of weight but doctors said he appeared to be healthy.
"He has lost seven kg till now. His blood pressure and heart beat are okay. He seems to be healthy. He is holding up," Dr Ravi R Kesliwal, who examined Hazare, told reporters here.
He said doctors were constantly monitoring his health.
Doctors last night said the Gandhian's condition was "stable" but there is reason to worry.
