Is Yolanda Foster Quitting 'Real Housewives of Beverly Hills?'

Foster was diagnosed with Lyme disease in 2012, and suffered a relapse in December of last year, which left her unable to read, write and even watch television. In the months since, Foster has traveled the globe in search of a cure.

"Everywhere you could be and get treatment, she's gone and tried it," Foster's co-star, Brandi Glanville, said during an interview with Access Hollywood on Wedensday.

As for what's next for Foster, Glanville said it is sure to be a long road to recovery.

"They just have to keep doing these treatments," Glanville explained. "She's on tons and tons of antibiotics, which we all know isn't great for you, and there's other autoimmune things that go along with this. It's just sad because she's so strong, and to see her a little defeated, I wish I could fix it.

The Real Housewives of Beverly Hills season five concludes on Tuesday, with the series' lost footage episode at 8 p.m. on Bravo.
