How To Prevent High Altitude Sickness
Morning sickness : Sometimes it could make it worse.Get a more detailed answer ›
As one ascends through the atmosphere, every breath contains fewer molecules of oxygen. One must work harder to obtain oxygen, by breathing faster and deeper. The % of oxygen in the atmosphere at sea level is 21%. As altitude increases, the % remains the same but the number of oxygen molecules per breath is reduced. At 12, 000 feet 40% fewer oxygen molecules per breath. Your ...Read more
Be Cautious: Climb slowly: let your body acclimate climb high, sleep low—sleeping at lower altitude then you have spent the day hiking lets body adjust hydrate if ill with headache, nausea, irritable, feeling hung over—go back down. Altitude can be fatal. Consider Diamox (acetazolamide) to prevent altitude sickness—talk to travel/ wilderness provider. It does not make you bullet proof ; still respect signs of sickness. ...Read more
How can high altitudes affect breathing, and how long does it take to acclimate to higher altitudes?
Depends on degree: This depends on the degree of illness. But I do agree with my colleague that descent -- safely -- is the first thing to do. Additional needs might be oxygen, hydration, the diuretic diamox (acetazolamide). If the person is confused, short of breath, and not moving well, this is severe and you're going to need help getting him/her down the mountain. Better to watch for early signs than let it get this far. ...Read more

A lot of migraine pts have motion sickness, and anti-migraine meds may be useful. ...Read moreSee 1 more doctor answer
Hemoglobin at altitu: Weeks to months depending on the altitude. The immediate response to altitudes over 10, 000 feet is an increase in the depth and rate of breathing to help maintain the level of oxygen in the blood. As the length of exposure persists, the kidneys will start producing a hormone to increase the rate of production of red blood cells to pick up and carry more of the available oxygen at that altitude. ...Read more
Many changes: 1. You breath faster to compensate for the thinned density of oxygen. 2 body makes more oxygen carrying red cells at altitude 3. Kidneys put out more bicarbonate (sodium bicarbonate) to keep your acid base state adjusted. Your rapid breathing blows off carbon dioxide and your kidneys adjust for this change but it takes a few days to body to alter. There are medicines to speed this acclimatization. ...Read more
Scuba: For commercial flights FAA recommends at least 24-48 hours between routine SCUBA and flying. If you suffered decompression sickness (DCS) after diving you should consult a military flight surgeon, FAA Aerospace Medical Examiner (AME) or hyperbaric medicine specialist for clearance before you fly. ...Read more
Altitude sickness: The risk of altitude sickness typically increases with the rate of ascension and elevation height. That is, the higher and faster one climbs, the worse the altitude sickness can become. The best exercise is altitude acclimatization and training in sequentially higher altitudes. Adequate hydration, avoidance of strenuous exercises, and certain meds can also help. Good luck and happy climbing! ...Read more
