Symptoms include severe headache, confusion, ataxia, drowsiness, stupor and coma
Acute altitude illness comprises acute mountain sickness, high altitude cerebral edema, and high altitude pulmonary edema
Although prophylaxis with dexamethasone for individuals Pathophysiology of acute mountain sickness and high altitude pulmonary oedema: an hypothesis
Dexamethasone has been found to reduce the incidence of high-altitude pulmonary oedema
Acetazolamide and dexamethasone have been shown to be effective agents for prophylaxis against high-altitude illness Dexamethasone is as effective as acetazolamide and starts acting within 12 hours while acetazolamide takes around 24 hours
Individual susceptibility is the most important determinant for the occurrence of high altitude pulmonary oedema (HAPE)
Panel B, Chest radiograph from the same patient after 1 day of treatment with supplemental Vasodilator Agents / therapeutic use
Individual susceptibility is the most important determinant for the occurrence of HAPE
Symptoms can include headaches, nausea, insomnia and fatigue
We assessed the effect of dexamethasone using established cell lines, including rat alveolar epithelial cells High altitude pulmonary edema is a potentially fatal condition that can affect those who climb above 8,000 feet
Objective: To investigate whether dexamethasone or tadalafil reduces the incidence of HAPE and acute mountain sickness (AMS) in adults with a history of HAPE
HACE is often thought of as an extreme form/end-stage of Acute Mountain Sickness (AMS)
HAPE is uncommon but can occur in people who rapidly ascend to High altitude pulmonary oedema is the presence of cough, dyspnoea at rest, reduced exercise tolerance and chest tightness along with physical signs of pulmonary oedema such as tachypnoea, Dexamethasone (2mg po q6h or 4mg po q12h, starting on the day of ascent) can be used in those who are allergic or intolerant of acetazolamide
Exposure to certain toxins
Another prevention method would be with using prophylaxis and dexamethasone
Every year about 2 percent of mountain climbers suffer from this life-threatening condition, according to Ken Kamler's 2005 article, "Steroids on Everest" on the National Geographic website
[1][2][3] Individuals ascending rapidly to altitudes >2500 m may develop symptoms of acute mountain sickness (AMS) within a few hours of arrival and/or high-altitude pulmonary edema (HAPE), which occurs High-altitude pulmonary edema (HAPE) develops in rapidly ascending nonacclimatized healthy individuals at altitudes above 3,000 m
you can take anti-sickness medicine or painkillers such as ibuprofen or paracetamol to ease symptoms

How common is altitude sickness? This varies with the location and with the way people tend to climb Risks of acute mountain sickness and high-altitude cerebral edema are reduced with the use of acetazolamide or dexamethasone; the risk of high-altitude pulmonary edema is reduced with the use of High-Altitude Pulmonary Edema
Both patients were managed with dexamethasone and they improved dramatically
This includes acute mountain sickness (AMS), high-altitude cerebral oedema (HACE) and high-altitude pulmonary oedema (HAPE)

Crossref Medline Google Scholar; Without proper acclimatization and continue to ascend, the illness may progress to the serious conditions of High Altitude Cerebral Oedema (HACE) and High Altitude Pulmonary Oedema (HAPE)
These areas include the role and potential mechanisms of brain swelling At any point 1-5 days following ascent to altitudes ≥2500 m, individuals are at risk of developing one of three forms of acute altitude illness: acute mountain sickness, a syndrome of nonspecific symptoms including headache, lassitude, dizziness and nausea; high-altitude cerebral oedema, a potentially fatal illness characterised by ataxia, decreased consciousness and characteristic changes In those with underlying heart or lung disease, effective control of congestive and respiratory symptoms can help prevent pulmonary edema
These areas include the role and potential mechanisms of brain swelling The treatment with Dexamethasone and Nifedipine is effective for HAPE [6,17], Ibuprofen is effective solely for headaches but not for HAPE

Acute mountain sickness (AMS) is a cluster of symptoms that commonly occur in those ascending to high altitudes
5–4% of predisposed previously healthy individuals who ascend higher than 3000 m37 People with HAPE report dyspnoea, cough, decreased exercise tolerance, or chest tightness, and exhibit signs of pulmonary oedema:
However, a trend has emerged in which Susceptible individuals can prevent HAPE by slow ascent, average gain of altitude not exceeding 300 m/d above an altitude of 2500 m
In a laboratory at 4559 m six subjects with high altitude pulmonary oedema (HAPO) characterised by clinical signs, severe hypoxaemia, widened alveolar-arterial oxygen gradient, pulmonary hypertension, and alveolar oedema on chest radiography were treated with nifedipine
