Former tennis star Martina Navratilova was hospitalized after he attempt to climb Kilimanjaro was cut short when she experienced high-altitude pulmonary edema (HAPE), a potentially fatal form of altitude sickness. HAPE is a dangerous build-up of fluid in the lungs.
Navratilova, 54, was climbing a variation of the 7 day Rongai route as part of a charity climb consisting of 27 team members. From her blog, it appears that she had complications beginning on day four, when the group camped at Horombo Huts (3,700 m/12,200 ft). She was escorted down the mountain and taken to Kilimanjaro Christian Medical Centre for treatment. As a precaution, she was flown to Nairobi Hospital for further tests.
