Yolanda Foster is becoming sicker with each passing day. The Real Housewives of Beverly Hills star is battling some very serious Lyme disease symptoms, and her husband believes she should quit the show.

Radar Online reports that filming for RHOBH is scheduled to begin this summer, and composer David Foster thinks his wife is too sick to take part in it.

“David has told Yolanda there is just no way she can return to the show because her condition is just getting worse. The Lyme disease is just ravaging her, and traveling for the international medical treatments is taking a toll,” a source says.

“Yolanda is extremely weak, and her memory is suffering,” the source adds. “David is just being protective because he doesn’t want any of the ladies to use her illness against her, as he knows those women are vicious.”

Yolanda Foster, mother of daughters Bella and Gigi Hadid, as well as son Anwar Hadid, has a soft spot for young people. She has recently provided some comfort as well as counsel to rocker Avril Lavigne, who also suffers from Lyme disease.

A source close to Yolanda Foster fears it will crush her if she can’t return to the Real Housewives of Beverly Hills.

“It will break Yolanda’s heart if she can’t be on RHOBH because she wants to use the platform to raise awareness about the illness.”

Surely Yolanda Foster will find other ways to raise awareness about Lyme disease. If filming the show is too much for her, then her husband is right to urge her to quit. Maintaining her health for her own well-being as well as that of her family is far more important than appearing on the Real Housewives of Beverly Hills.
