Motion sickness refers to motion sickness, and common causes include personal constitution, visual abnormalities, and vestibular dysfunction. Treatment includes rehabilitation training, medication and surgery. 1. Personal constitution: such as physical weakness, excessive hunger or overfeeding, suffering from inner ear disease, etc. may cause motion sickness. Adjustment methods are mainly to detach from the disease-causing environment, avoid sitting in the car under the condition of excessive hunger or overfeeding, and treat the underlying diseases. 2. Visual abnormality: When the human body is constantly moving or changing direction, if the vision produced is not coordinated with the sense of movement, vertigo will occur. Measures to deal with this are to avoid reading books or looking at cell phones while riding in a car, and to try to keep your eyes flat in front of you and look at stationary things. 3. Vestibular nerve abnormality: the vestibular nerve is the main sensory organ of the human balance system, if the vestibular nerve abnormality will cause vertigo. Commonly used drugs include Benadryl, etc., mainly through the inhibition of central nervous excitability to relieve motion sickness. In severe cases, vestibular neurectomy can be performed. The above mentioned people can also improve the symptoms of motion sickness through environmental training (e.g. exercise environment) and balance training. In addition to the above, motion sickness can also be caused by changes in the thickness of the otolithic membrane and diseases of the inner ear. If the above symptoms are severe, it is recommended to go to the hospital in time to identify the cause of the disease and give regular treatment under the guidance of the doctor. The above medications should be applied under the guidance of a pharmacist or doctor.
