Is altitude sickness worse for people who get carsick?

The plateau reaction is not necessarily more severe in people with motion sickness, and there is no obvious link between motion sickness and the pathological mechanism of plateau reaction.
Motion sickness is generally referred to as motion sickness, which is caused by heredity, excessive fatigue, inner ear disease or vestibular function abnormality or induced by environmental high humidity, high temperature, poor ventilation or noise, causing vertigo, epigastric discomfort, nausea, pallor and other symptoms.
Plateau reaction refers to the plateau hypoxic stress reaction after entering the plateau area from the plains or entering the high altitude area from the low altitude, there is no obvious relationship with motion sickness, and healthy people may also have plateau reaction after entering the plateau area. Therefore, motion sickness is not necessarily more serious plateau reaction.
If people with motion sickness want to prevent plateau reaction in advance, they should actively go to the hospital, consult a professional doctor, follow the doctor’s advice and use medication, not self-medication, so as not to delay the condition.
