title: [HIGH ALTITUDE EXPOSURE IN TRAVELERS WITH PREEXISTING MEDICAL CONDITIONS].
abstract: The number of travelers visiting high altitude regions is increasing. High altitude areas have become more accessible in recent years, and reaching areas at altitudes over 3000 meters above sea level has become more common than before. In many circumstances older travelers, who are more likely to have pre-existing chronic diseases and for whom altitude and hypoxic condition might be a risk, reach high altitudes in a fast and tight schedule, therefore having a shorter time for adaptation and acclimatization. Pre-travel consultation, including the discussion of chronic illnesses and medication use, is therefore crucial for the reduction of the risk of acute mountain sickness and preventing the deterioration of their pre-existing medical conditions.
