Jennie Garthisn’t letting her early-onset osteoarthritis diagnosis slow her down.
TheBeverly Hills, 90210alum, 50, toldInsiderThursday that she was diagnosed with the condition at 47 years old after feeling stiffness in her fingers and hands, as well as pain in her knees.
“I was like, I’m too young for arthritis,” she said. “When you hear the word arthritis, you associate it with the elderly and people who are immobile, who can’t live an active life.”
Garth refused to allow the diagnosis to stop her from having an active lifestyle, though, telling the outlet, “It was just a new, interesting development in my maturing. You don’t think of yourself as slowing down or anything stopping you from all the things you do every day.”
“When you know what you’re dealing with physically, there’s always a workaround,” she added. “I definitely don’t let anything limit me.”

Osteoarthritis is the most common form of arthritis and occurs “when the protective cartilage that cushions the ends of the bones wears down over time,” according to theMayo Clinic.
The mother of three enjoys playing golf and hiking with her dogs, according to Insider. She also uses stretching to help improve symptoms.
Garth told the outlet she is not taking medication for her condition but applies an over-the-counter gel that provides “relief” from joint pain.
