Altitude Illness is common in higher altitudes, where the amount of oxygen is considerably lesser than sea level. It mostly occurs when the body can’t acclimatize to the new surroundings while we are in high hills and mountains. Cold, low humidity, increased UV radiation, and lower air pressure are all stressors of the high-altitude environment, all of which can pose issues for travellers. Hypoxia, on the other hand, is the major worry. The severity of hypoxic stress is determined by altitude, rate of climb, and exposure time. The greatest hypoxia is produced when sleeping at high altitudes; day visits to high altitudes followed by a return to low altitudes are far less taxing on the body.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The human body adapts to mild hypoxia extremely effectively, but it takes time(Box 2-02). Acute acclimation to high altitude takes 3 to 5 days to complete. It is essential to acclimate for a few days at 8,000\u20139,000 feet (2,500\u20132,750 meters) before moving to a higher elevation. Acclimatization reduces the risk of altitude sickness, improves sleep quality, and enhances overall comfort and well-being. Exercise performance should be reduced slightly at high altitude compared to low altitude. The most important element in acute acclimatization is increased ventilation; therefore, respiratory depressants must be avoided at all costs. In extreme acclimation, increased red-cell production has little effect.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

Risk for travellers<\/strong><\/p>

Any tourist travelling to altitudes of 8,000 feet (2,500 meters) or above may get altitude sickness due to insufficient acclimatization. Altitude sickness susceptibility and resistance are inherited characteristics, and there are no easy screening methods to identify risk. Training and physical fitness have little effect on risk. Children and adults are both vulnerable, however individuals over the age of 50 are at a somewhat reduced risk.<\/p>

The most trustworthy indicator for future expeditions is how a tourist has responded to high altitude in the past, although it is not infallible. However, assuming a certain level of sensitivity, the rate of climb and effort have a significant impact on the risk (see Table 2-07).Because of differences in individual sensitivity, as well as starting places and topography, determining a route that will prevent any occurrence of altitude disease is challenging. The traveler’s objective may not be to prevent all symptoms of altitude sickness, but to keep any symptoms to a minimum.<\/p>

Clinical Presentation<\/p>

Acute mountain sickness (AMS), high-altitude cerebral edema (HACE), and high-altitude pulmonary edema (HAPE) are the three types of altitude illness.<\/p>
