Is high altitude bad for aortic aneurysms?

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 more

High Altitude (Definition)

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

How does the body acclimate itself to high altitude?

How does the body acclimate itself to high altitude?

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

If my baby was born in high altitude are they used to it?

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

Help docs! i'm trying to find out what causes high altitude cerebral edema?

Hypoxia: When a person goes to high altitude, they are naturally exposed to hypoxia as oxygen content decreases with elevation. Most who climb can to aclimatize to this change. However, in certain people they are not able to compensate. The proton pumps that maintain the blood brain barrier cease to function and there is extra fluid (edema) in the brain that leads to brain swelling. This can lead to death. ...Read more

Diagnosed with polycythemia vera without mutation in JAK2. What else might be the cause? Do not smoke and do not live in high altitude.

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

Can I have a retinal hemorrhage from high altitude?

Can I have a retinal hemorrhage from high altitude?

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
