“She 100 percent has Lyme disease, and she’s absolutely suffering,” Richards told PEOPLE Now just weeks after the Real Housewives of Beverly Hills season 6 supertease (which PEOPLE exclusively premiered) showed some of the Housewives seemingly questioning their costar’s diagnosis.
Richards said the Housewives’ doubts were about whether “there was something in addition” to Foster’s Lyme disease, which she was diagnosed with in 2012.
“Because you know, she 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,” Richards explained. “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.”
“I don’t think anyone doubts that she has Lyme disease, I think they were wondering about other things as well,” Richards added.
The reality star, 46, also fiercely denied any similarities between Foster’s health struggle to the health scandal unfolding on the Real Housewives of Orange County surrounding Vicki Gunvalson‘s ex Brooks Ayers, who recently confessed to forging medical documents to prove he has cancer.
“You cannot compare the two situations,” Richards said. “What they went through in Orange County and what was going on there, we didn’t know [about] and it is a very different situation. Someone completely inventing that they have something, for whatever reason – attention, I don’t know. Yolanda is sick. Yolanda is suffering. She has Lyme disease, 100 percent.”
The Real Housewives of Beverly Hills airs Tuesdays (9 p.m. ET) on Bravo.
