The 'Requiem for a Dream' star has been diagnosed with gout, immediately after he lost a considerable amount of weight. Leto is well known for the way he likes to involve himself in every project that he undertakes, and for the physical changes that he is more than willing to submit himself in order to identify himself with a character.

Recently, the hunky blue-eyed actor and rocker became really fat, gaining more than 62 pounds, for his part as John Lennon's killer, David Chapman, in the upcoming movie 'Chapter 27'.

But he immediately signed on for another movie and all those extra pounds had to be lost rapidly.

Consequently, he developed the disease called gout, whose set-off is caused by the accumulation of uric acid crystals in the joints and mainly characterized by sudden and intensive pains, associated with redness, swelling and stiffness in the joints.

Jared's spokesperson confirmed the fact that his client has gout during a press release, but he did not mention whether he will be admitted into a hospital for treatment or not.
