It might be two entirely different problems. Researchers discovered this by applying network theory to medicine, analyzing the correlations between symptoms from a sample of people traveling to high altitudes.
When they then mapped those symptoms as a network, they suddenly saw three very different patterns. There is mounting evidence that headaches and sleep disturbances are caused by different mechanisms. The researchers examined 16 climbers who had previously experienced HAPE and 14 who had not.
They also gauged the permeability of the pulmonary capillaries. Their goal was testing a common belief that HAPE results when the lower air pressure at high altitudes causes lung capillaries to swell or when the capillaries begin to leak as a result of inflammation. The researchers examined the subjects at a low altitude of meters and then at 4, meters 24 hours later.
The team also found that among those susceptible to HAPE, the ones who actually developed HAPE all had higher pulmonary capillary pressures than the rest. Based on these findings, Maggiorini suggests that pulmonary edema can be treated with vasodilators to lower pulmonary capillary pressures.

A lack of oxygen at high altitude combined with the subsequent changes in pressure within the blood vessels causes fluid to leak through tiny blood vessels into the brain, which leads to swelling. Usually, HACE occurs when a person stays at a high altitude for at least 1 week.
If this condition is left untreated, there is a very high risk of death. A person presenting symptoms of HACE should descend immediately. HAPE causes fluid to build up in the lungs, preventing oxygen from getting into the bloodstream.
As HAPE progresses and blood oxygen levels drop, several symptoms may develop, including:. This complication can be fatal if it is left untreated. If a person is fully conscious and can reach a health facility, medical professionals can treat HAPE at that altitude with oxygen supplementation. However, in a more remote setting, a person should descend as soon as is practical.
Both of these conditions are uncommon, but may occur if a person ascends to a very high altitude too rapidly and stays there. Altitude sickness is best prevented by a measured ascension, allowing time for gradual acclimatization. However, a person may be able to take other precautions. These are particularly important should a person climb in a more remote setting where immediate health care will not be available. They include:. Altitude sickness occurs when a person rapidly ascends to high altitudes, normally above 8, ft.
Symptoms of altitude sickness can include headaches, dizziness, and shortness of breath. If a person stays at high altitudes for an extended period, they may develop chronic altitude sickness. If they do not get medical help, this can lead to potentially fatal complications. A person can prevent altitude sickness by ascending gradually and allowing the body to acclimatize to new heights. A doctor may prescribe several different medications to treat altitude sickness, or in some cases, recommend oxygen supplementation.
However, a person may remedy altitude sickness symptoms most effectively by descending to lower altitudes. Anoxia occurs when a person's body or brain stops getting oxygen.
