Foster was diagnosed with Lyme disease in 2012, around the time she was brought aboard The Real Housewives of Beverly Hills' third season. Then, in 2014, as she wrapped filming on season five, Foster suffered a Lyme disease relapse, which left her unable to read, write and watch television. Foster was also unable to continue participating in her weekly Bravo blogs, and was forced to leave filming early on the season five reunion.

"I would like to apologize for my lousy participation in the blogging department at the moment," Foster explained to fans after the season concluded. "Although writing is usually my favorite thing to do, I unfortunately have lost the ability to do so in an intelligent matter at this time."

"Most of you know I have been battling Lyme disease for the past three years," Foster continued. "I wasted the first year trying to get diagnosed and spent the next two trying to find a cure. I have gone from the conventional long-term antibiotics to about every holistic protocol there is to offer. Unfortunately, I was only able to get to about a 60 percent recovery until I relapsed in early December and have not been able to find my way back."
