The actor took to Twitter to address his previous health condition after footage of him discussing his diagnosis with a rare form of vasculitis was released.
"Before there are a bunch of rumors/ chatter/ whatever out there," Ashton began his Aug. 8 tweet. "Yes, I had a rare vasculitis episode 3yrs ago."
The 44-year-old went on to share that the "autoimmune flair up" led to impairments of his hearing, vision and balance. However, Ashton noted, "I fully recovered."
"All good," he added. "Moving on."
As for what Ashton is moving on to, he shared at the end of his tweet that he will be at the 2022 New York City Marathon with Thorn, the company he co-founded with ex-wife Demi Moore dedicating to defending children from sexual abuse.
Ashton's health update comes after Access Hollywoodshared a sneak peek of his upcoming Running Wild with Bear Grylls episode. In the footage, Ashton discussed his diagnosis.
"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 said. "It took me like a year to build it all back up."
While Ashton has recovered and feels "lucky to be alive" after the medical scare, the father of two explained how the experience adjusted his outlook on life.
"The minute you start seeing your obstacles as things that are made for you, to give you what you need, then life starts to get fun, right?" he said. "You start surfing on top of your problems instead of living underneath them."
