Uncertainty over the medical condition of megastar Amitabh Bachchan created a mild flutter here Monday but the hospital he is being treated in insisted he was recovering though it was too early to say when he would be discharged.

"There is no deterioration in his health and he is showing signs of improvement, " Lilavati Hospital spokesperson Mohan Rajan told.

"The doctors are not ready to comment about his getting discharged and the sort of tests he is undergoing, respecting the privacy of the actor. We don't want any baseless rumours to surface. He needs rest, " Rajan added.

However, a source at the hospital said Amitabh's abdominal pain resurfaced due to unknown reasons and an endoscopy had to be performed on him.

"The doctors are trying to diagnose the cause of the pain, " the source told.

The source also said that henceforth, the Bachchan family and not the hospital would be issuing statements on the actor's condition.

"Whatever statement will be issued now will come from the Bachchan family and not from the hospital, " the source said.
