Prophylaxis: 125-250 mg PO bid starting 1 d before ascent and continued for 2 d or the duration of stay at altitudeĬarbonic anhydrase inhibitor: Causes bicarbonate diuresis and decreased production of CSF. With longer stays at altitude, these symptoms improve in a process known as acclimatization. These individuals frequently experience acute illness soon after ascent. With the availability of easy transportation into the mountains, not just for climbing but also for skiing and other forms of recreation, thousands are exposed to high altitude each year. Even today, many questions regarding the precise mechanism of altitude illness remain unanswered.ĭespite the obvious dangers inherent in climbing and the altitude-related illness experienced by nearly all who spend significant time in the mountains, people continue to seek the remoteness and pleasures of high places. By the beginning of the 20th century, hypobaric hypoxia was known to be the main cause of these symptoms. Some early climbers mentioned experiencing the symptoms now described as mountain sickness. Most peaks in the Alps had been climbed by the end of the 19th century. Mountains have fascinated and attracted humankind for millennia.
