Bollywood actor Irrfan Khan yesterday said he is suffering from "a rare disease" and will share details when there is a conclusive diagnosis but did not disclose what it is.

In a post on his Twitter account, the 51-year-old actor, who starred in Bangladeshi director Mostafa Sarowar Farooqi’s film “Doob, said he and his family were jolted by the knowledge of his illness and requested his fans and followers not to "speculate" about his health, reports our New Delhi correspondent.

"Sometimes you wake up with a jolt with life shaking you up. The last fifteen days, my life has been a suspense story. Little had I known that my search for rare stories would make me find a rare disease. I have never given up and have always fought for my choices and always will,” the actor wrote on the micro-blogging site.

"My family and friends are with me and we are working it out the best way possible. In trying times, please don't speculate as I will myself share with you my story within a week - ten days, when the further investigations come with a conclusive diagnosis. Till then, wish the best for me," Irrfan said.

On February 21, the actor's spokesperson had released a statement saying that he has been diagnosed with a "severe case of jaundice,” reports our New Delhi correspondent.

Next day, Bollywood director Vishal Bhardwaj, who was scheduled to begin the shoot of his next movie, starring Irrfan and Deepika Padukone, postponed the filming of the project citing health concerns of his lead actors.
