Mrs South Africa, Nicole Capper, is in a stable condition after she was airlifted to Kathmandu hospital in Nepal, after she suffered from altitude sickness during a Mount Everest expedition.

Nicole left the country on April 2 as part of an expedition to raise funds for Rare Diseases South Africa.

It is a cause that is close to her heart as she's a mother to a little girl named Tatum, who suffers from cystic fibrosis.

Mrs SA pageant director Joani Johnson told TshisaLIVE that the team in Nepal notified them this morning that Nicole had fallen ill.

"We were notified this morning that Nicole was not feeling well after they reached the Everest base camp yesterday and that she was airlifted to hospital. We have been informed that she is in a stable condition and will have updates as more information becomes available," Joani said.

At the start of the expedition Nicole said on social media that she would be climbing for all those suffering from a rare disease.

"I want to climb every step for those who can't, take every breath for those who can't, and experience the outdoors like some can only dream of."
