Megastar Amitabh Bachchan often shares his health issues with the public, and this time he admitted that 75 percent of his liver is gone.

"I keep quoting my personal example all the time and try and propagate the idea of getting yourself detected and I don't mind saying this publicly I am a tuberculosis survivor, Hepatitis B survivor... Bad blood infusion went in and 75 percent of my liver is gone but because I was able to detect it even after a period of 20 years, when 75 percent of my liver is gone... I am still surviving on 25 percent," Big B said at NDTV's Swasth India launch.
