“Mega superstar Amitabh Bachchan on Monday underwent treatment for abdominal pain at the Escorts Heart Institute for nearly eight hours and was later flown to Mumbai where he will be admitted at the Leelavati Hospital.

Wrapped in a cream-coloured shawl and donning a red monkey cap, the 63-year-old Bachchan, upon discharge from the hospital, was helped into a luxury car with Samajwadi Party leader Amar Singh, in tow.

The ’shahenshah’ of Hindi film industry looked weak as he came out of the hospital and sat in the car with the help of son Abhishek Bachchan , while Jaya Bachchan was escorted away by son-in-law Nikhil Nanda.

Leading cardiologist and Director of Escorts Naresh Trehan, maintained that Bachchan’s illness was “nothing serious and just a normal irritation in the intestine.”

“He came with complains of pain in the abdomen for which we have investigated him. Nothing serious has been found and he is now being discharged,” Trehan told reporters earlier.

He said doctors conducted several tests, including those of the blood, ultrasound treatment, X-ray and CT Scan.

Asked why Bachchan was admitted to Escorts, a heart institute, Trehan said “he knows me, he knows the doctors here, and we are the best hospital in this part of the world. It’s true, I am serious.”

Asked whether it was a case of food poisoning, he said “it was something like that.”

Bachchan and his family members had come to New Delhi in the wee hours of the day after attending a function to commemorate his litterateur father late Harivanshrai Bachchan’s birth anniversary.

Uttar Pradesh Chief Minister Mulayam Singh, visited the superstar in hospital.
