Wrestler-actor Dara Singh continues to be very critical and is now undergoing dialysis, a doctor said on Monday.
The 84-year-old was taken to the Kokilaben Dhirubhai Ambani Hospital on Saturday following a severe cardiac problem.
He remained critical on Sunday, and his condition hasn't improved since.
"He is still very critical. His condition has not deteriorated and he is holding up, but he requires a high dose of medication. The problem he came up with during hospitalisation has now affected his kidneys. His kidneys are not functioning the way they should, so we have to put him on dialysis," Ram Narain, COO, Kokilaben Dhirubhai Ambani Hospital, told IANS.
Dara Singh, who won the title of "Rustam-e-Hind" for his wrestling prowess, entered the film world in the 1960s.
He appeared in various films like Watan Se Door, Dada, Rustom-E-Baghdad, "Sher Dil", "Sikandar E Azam", "Raaka", "Mera Naam Joker and "Dharam Karam". He was last seen in a 2007 release "Jab We Met".
He has also done TV serials and is best known for his portrayal of Hanuman in "Ramayan".
