Symptoms generally associated with more severe altitude illness include:
Altitude sickness is caused by changes in the distribution of oxygen and pressure. The symptoms of altitude sickness resemble those of a cold.
Altitude sickness reduces the amount of oxygen in the brain, causing such symptoms as dizziness, shortness of breath, and mental confusion
The lowest recorded case of serious altitude sickness (HAPE) was at 2500m in a climber in Japan. However, most people need to travel above 3000m and stay there for at least 12 hours before symptoms of altitude sickness develop.
Some of the more common symptoms of altitude sickness are headache, loss of appetite, and trouble sleeping. The reason this happens is because studies have shown that at higher altitudes, the brain or your body, is not getting enough oxygen. The best treatment for altitude sickness is to drink plenty of water, take over-the-counter medication for the headache if you have to, and try not to be overly active.
It depends upon the person, but the most common symptoms are headaches, nausea, vomitting, and fatigue. The people that are most prown to altitude sickness are those of 50 years and up, if you have a history of altitude sickness to start with, places that are 3,000 feet or higher, or a rapid change in altitude. As a young child, I used to have altitude sickness because I had problems with my ears, so that could also effect you. The last time I went up to a higher elevation, I used these band like bracelets called "Sea Bands" from the "Sea Products" company and those really seemed to help me. You can get them and/or pills for altitude sickness over the counter.
Yes, but most people who get altitude sickness just feel flu-like symptoms for 1 or 2 days and then feel better. At very high elevations altitude sickness can progress to high altitude pulmonary edema (HAPE) or high altitude cerebral edema (HACE), both of which can be fatal. If you are below 4200m and get altitude sickness the best remedy is to descend to a lower altitude, drink lots of water, and avoid physical exertion. If you are going above 4000m do more research before you go and get advice from someone who knows more than me.
In both cases , low availability of oxygen to the body cells.

Hypoxemic anoxia can be avoided by utilizing supplemental oxygen when in high altitudes and being aware of the early symptoms of altitude sickness and reducing altitude once recognized.
Altitude sickness occurs when people increase altitude too quickly. What is the cause of altitude sickness? Acute mountain sickness is caused by reduced air pressure and lower oxygen levels at high altitudes. The faster you climb to a high altitude, the more likely you will get acute mountain sickness. You are at higher risk for acute mountain sickness if: You live at or near sea level and travel to a high altitude. Oct 16, 2017
You're probably wondering about Acute Mountain Sickness (AMS), more commonly known as 'altitude sickness'. Altitude sickness happens when you're not acclimated to the mountains. The symptoms are often described as flu-like, such as nausea, vomiting, weakness, dizziness, tingling, drowsiness, and general malaise. All of these symptoms are effects of going to a higher elevation, and the symptoms usually resolve in a couple days when the body acclimates. The best way to avoid altitude sickness is to allow the body maximum time to get used to the change in altitude. Rest for a full day before engaging in more strenuous activities, and drink plenty of water. At higher altitudes, a person is more prone to dehydration. Hydration before the symptoms take place is ideal. Also be sure to eat a balanced diet, even if you don't feel hungry. If you do end up with altitude sickness, hang in there. You should feel better in a day or two.
