Yolanda Foster "100 Percent Has Lyme Disease," According to Kyle Richards

Yolanda Foster has been very public about her struggles with Lyme disease. The Real Housewives of Beverly Hills model has never been shy to let fans into her ongoing issues with the disease — which is why it may have been surprising that some of the RHOBH women are questioning her illness, as seen in the Season 6 trailer (above). Now, Kyle Richards is speaking up about those doubts.

"She 100 percent has Lyme disease, and she's absolutely suffering," Kyle told People. "I don't think anyone doubts that she has Lyme disease, I think they were wondering about other things as well."

Kyle added that the other women have wondered about whether or not "there was something in addition" to Yolanda's Lyme disease. "Because you know, [Yolanda] went through a lot of different things to try to feel better — she took out the mercury in her fillings and she had implants and she took those out — she was doing everything and flying all over the world to do every kind of treatment you could imagine," she said. "And so I think that's why a lot of eyebrows were kind of raised, but she absolutely has Lyme disease and is 100 percent struggling. Every day is a struggle for her."

Kyle's comments about Yolanda's health come in the wake of the news that Yolanda and David Foster are divorcing after four years of marriage. Kyle addressed the couple's split on Watch What Happens Live, below.
