Megastar Amitabh Bachchan said he will have to undergo a second surgery and that his stay in the hospital will be prolonged.
Bachchan, 69, who underwent an abdominal surgery on Saturday at the Seven Hills hospital, said on Twitter that he was required to make another visit to the operation theatre.
"Some more tests... more unpronounceable medication...and... another visit to the OT... operation theatre! Going to be a long stay," the actor tweeted, without giving details.
"I have no idea now how long this will take, but it does look as though it will be long... thank you for your prayers and love," he added.
Admitted to the hospital on Saturday, Bachchan, who has been bravely updating his fans on his medical condition, posted a brief entry on his blog last night.
"I seek forgiveness... I will not be detailing any more... Some fresh medical issues have come up, and I need to concentrate on the treatment now," he wrote.
Earlier on Wednesday, Bachchan had tweeted, "Cure can be distasteful till it begins to work... till that happens, your faith in it diminishes by the minute... then suddenly AIW : All Izzz Well...!!," he posted.
After his first surgery, the actor had tweeted he was in acute pain.
Bachchan has been battling a string of stomach ailments since his near fatal intestinal injury while filming a fight scene in 1982 movie Coolie.
