TYPES
The three types of high altitude illness are as follows:
Acute mountain sickness. This is the most prevalent manifestation of the disease. It’s usually mild and only lasts a few days.
High altitude pulmonary edema. This illness causes fluid to build up in your lungs, which can be devastating.
High altitude cerebral edema. This type causes the fluid in your brain to enlarge, which can be deadly.

High-altitude symptoms usually appear 12 to 24 hours after reaching a high altitude. Early signs and symptoms include:
