high-altitude cerebral edema

High-altitude cerebral edema (HACE) is a serious condition that occurs when, at very high elevations, the brain swells due to increased pressure and fluid buildup caused by reduced oxygen levels. As you ascend rapidly without proper acclimatization, the body’s response can lead to swelling in the brain, resulting in symptoms like severe headache, confusion, loss of coordination, and even coma. It’s a medical emergency that requires immediate descent to lower altitude and medical treatment to prevent lasting damage or death. Proper acclimatization and awareness of symptoms are essential for high-altitude travelers.
