In a sneak peek at this week’s episode, the “That ’70s Show” star opens up about a private health battle when asked where his strength comes from.
“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,” he revealed in the footage, first shared by Access Hollywood. “It took me like a year to build it all back up.”
“You don’t really appreciate it, until it’s gone. 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,'” he added — telling Grylls he’s “lucky to be alive.”
According to the Mayo Clinic, vasculitis is an inflammation of blood vessels which can lead to organ and tissue damage. Treatment includes taking a corticosteroid like prednisone or methotrexate to get the inflammation under control.
“The minute you start seeing your obstacles as things that are made for you, to give you what you need, then life’s supposed to get fun, you start surfing on top of your problems instead of living underneath them,” Kutcher adds in the clip.
“Hearing Ashton’s story about his autoimmune disease, that’s a terrifying journey but it’s also part of why he’s strong and resilient,” said Grylls after Kutcher’s reveal. “What do they say in survival? Storms make you stronger and I think he’s living proof of that.”
Ashton’s episode of “Running Wild with Bear Grylls: The Challenge” airs Monday on National Geographic.
