Yolanda Foster of "The Real Housewives of Beverly Hills" is not giving up as she continues to find a cure for Lyme disease. The reality TV star recently updated her Instagram followers about her health condition by posting a photo of her receiving hyperbaric oxygen treatment on Monday, July 6. 

In the photo, the Bravo star is seen wearing a white sweatshirt with a yellow smiley face printed on it along with the words "Keep Smiling." The star grins for the camera as she lies inside the hyperbaric chamber, and the shot was captioned, "Back at work…#HyperbaricChamber #ChronicLymeDisease #DeterminedToFindACure." 

Hyperbaric oxygen treatment entails the medical use of oxygen at a level higher than atmospheric pressure. Although the treatment cannot cure a person of Lyme disease, increased oxygen levels in the body can cause the reduction of harmful bacteria, which will lessen the debilitating effects of the disease. Right now, there is no known cure for Lyme disease. 

Meanwhile, in a rare modeling photo shoot for W magazine, the former model looked vibrant and happy as she posed for the camera on a luxurious bed. In the photo, Yolanda is wearing a white shirt and a printed skirt. 

The star told the magazine that when she joined "The Real Housewives of Beverly Hills" in its third season, she was expecting to have more than her share of fun. But almost immediately after joining the hit franchise, the star was diagnosed with Lyme disease. 

"I had much more glamorous plans for myself obviously," she told W.

Instead, the mother-of-three is now focusing her energy on raising awareness for the debilitating disease through various avenues, including her Instagram page. She noted that the photo sharing app has been very useful for spreading the word about Lyme disease, and it has also been a useful tool for her daughters, Gigi and Bella Hadid. 

"When I was modeling 30 years ago, we didn't have that," she said of the social media site, adding that back then, models had to run around with portfolios and "beg" for jobs. 

"Now these kids establish themselves on social media and they just run with it," she added.
