Is High Altitude Bad For Aortic Aneurysms
Depends: This is a difficult one to answer. The changes that may occur at high altitude, such as relatively less oxygen may lead to increased heart rates, especially with exertion, and that is an undesirable effect. However, more details are needed: location of the aneurysm? Size and the etiology of the aneurysm?M how far above sea level is your location? What would be a rate of ascent? ...Read moreSee 1 more doctor 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
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
Not well studied: Very likely. The particular risks for children to high altitude have not been thoroughly studied. Children born ; living at altitude to have normal risk for high altitude pulmonary edema but there may be some increased risk for this condition if a child then travels down to lowland ; then re-enters high altitude. Very small older studies are suggestive but reasons are not clear.New info pending. ...Read more
Not a problem: Assuming your general health is good enough to permit higher altitudes, just use your CPAP machine as usual. It will work as it always does. Of course, you will have less oxygen in the ambient air, but it will continue to do it's job. If you don't have a cpap, get one, or if intolerant of its use, see your dentist about having an oral appliance made as an alternative. ...Read moreSee 1 more doctor answer
Diagnosed with polycythemia vera without mutation in JAK2. What else might be the cause? Do not smoke and do not live in high altitude.
Interesting question: Do you have polycythemia rubra vera or polycythemia which is assosciated with stress? Have you had a bone marrow examination. Do you have an hemoglobinopathy? Glad you do not smoke and glad you do not live in high altitudes, because these increase blood counts. Are you an athlete. Do you have any hormonal questions too much testosterone? Please see an hematologist to clarify. ...Read more
I have mŽnire's disease. We just moved to georgia in the mountains. Can living in high altitude worsen vertigo? I seem worse since moving here.
Yes, however:: At altitude above 4300 meters, there are certainly reports of retinal hemorrhage but it can be difficult to exclude other causes.High altitude retinopathy (harh) is seen in up to 29% of everest climbers above 5300 meters. There seems to be an association with altitude sickness raising questions whether slow ascent ; other factors may reduce risk for bleeding in the small vessels of the eye. ...Read more
It's possible...: ... But other causes should be ruled out. Retinal hemorrhages are more often caused by uncontrolled hypertension or diabetes, as well as occasional association with bad floaters. The decreased pressure from high altitude has been known to rupture small blood vessels on the white of the eye as well. Have your eye doctor examine you carefully. ...Read moreSee 1 more doctor answer

Certainly, Examples:: 1.Your bone marrow will makes more oxygen carrying red cells at altitude 2.The body produces more of a particular enzyme which increases release of oxygen from hemoglobin to the body tissues 3.Your kidneys adjust the acid base state of your body by changing amount bicarbonate (sodium bicarbonate) excreted. 4. Pulmonary capillary pressure increases, forcing parts of the lung to work that are dormant at sea level. ...Read more
