"My father has intestinal problems and is doing well now. He is responding well to the medicines," actor Abhishek Bachchan [Images] told reporters outside Lilavati Hospital on Saturday night.

Dressed in a white Pathani suit, Abhishek has been with his father since Saturday afternoon when the latter was taken first to Mumbai's Nanavati hospital after he complained of stomach pain.

"My father will remain in hospital for the next 48-72 hours and I thank all his fans and you journalists for being supportive of our family at this juncture," Abhishek said in a one-minute interaction with media-persons.

Bachchan Sr developed pain in his stomach on Friday night, a day before his 66^th birthday.

He did not celebrate his birthday as his mother Teji Bachchan had passed away in December 2007.

After the pain became severe he was rushed to Juhu's Nanavati hospital on Saturday afternoon, which is near his home, and was discharged in one hour's time.

Everyone thought the worst was over, but the superstar was soon rushed to Lilavati Hospital in Bandra, north-west Mumbai, where he had been operated upon for intestinal problems in 2005.

He was taken inside Lilavati Hospital on a stretcher and was seen to be in pain.

Abhishek Bachchan, his wife Aishwarya [Images] Rai-Bachchan and sister Shweta Nanda and family friend Amar Singh [Images] too accompanied the superstar, and wife Jaya Bachchan joined them soon after.

The doctors at Lilavati Hospital have stated that Bachchan Sr's medical reports will come in on Sunday morning, after which they will decide on the further course of treatment.
