David and Yolanda Foster are one of the wealthiest couples on the Real Housewives of Beverly Hills, but the reality star's battle against lyme disease is reportedly putting the squeeze on their assets.
The 49-year-old former model has been undergoing experimental treatment for her chronic neurological disease, a condition that has already robbed her of the ability to read and write. Her music composer hubby has been footing the bill without hesitation, but the costs are adding up.

“The experimental treatments aren’t covered by Yolanda’s medical insurance and require travel out of the United States, typically to Asia,” a source told 'Radar Online.' “Yolanda travels first class, and the medical care is very, very expensive. David has spent more than a half million dollars on medical care for Yolanda.”

“There is a lot of pressure on David both financially and emotionally as he watches Yolanda struggle with this,” the source added. “Yolanda is continuing to have problems with short term memory, but she is refusing to give up.”

The blonde beauty recently posted a photo of her receiving medical treatment abroad and offered her own explanation for the travel requirements, saying, “A lot of great medicines and ancient therapies are blocked by the FDA, so that’s why I choose to travel and recognize the value of diverse points of view in medicine."
