Ashton Kutcher reveals autoimmune disorder left him unable to see, hear or walk

Ashton Kutcher reveals autoimmune disorder left him unable to see, hear or walk. Access Hollywood shared a sneak peek they had obtained from an upcoming episode of National Geographic’s “Running Wild with Bear Grylls: The Challenge,” where the actor spoke about a rare autoimmune disorder he developed.

“Like two years ago, I had this weird, super rare form of vasculitis, that like knocked out my vision, it knocked out my hearing, it knocked out like all my equilibrium.” It took him about a year to build each back up again, Ashton revealed to Bear Grylls.

Vasculitis is a rare autoimmune disorder with many variations which can cause inflammation of the blood vessels, restricting blood flow and leading to organ and tissue damage in some.

“You don’t really appreciate it, until it’s gone,” he said, “Until you go, ‘I don’t know if I’m ever going to be able to see again, I don’t know if I’m ever going to be able to hear again, I don’t know if I’m ever going to be able to walk again’.”

“Lucky to be alive,” he says.

“Lucky to be alive,” Bear echos.
