Vertigo is a sensory abnormality in which patients feel that they or their surroundings are rotating or shaking, often accompanied by balance disorders. It is mainly caused by ear or brain lesions, but can also be caused by blood, endocrine system or systemic diseases. The pathogenesis of vertigo has a variety of factors, which can vary depending on the cause. The most common ones are: 1. Meniere’s disease: It may be caused by lymphatic metabolism disorder in the inner ear, which causes fluid accumulation in the vagus of the inner ear membrane. 2. Labyrinthitis: It is often caused by direct destruction of the bone wall of the vagus by middle ear lesions (cholesteatoma, etc.) or, in a few cases, by infection. 3. Drug intoxication: It is caused by sensitivity to some drugs such as streptomycin and gentamicin, which cause damage to the inner ear. 4. Motion sickness: It is caused by motion sickness or seasickness. It is caused by mechanical stimulation of the vagus in the inner ear when riding in a car, boat or airplane, resulting in disturbance of balance function. 5. Insufficient blood supply to the vertebrobasilar artery: This is also commonly referred to as insufficient blood supply to the brain, and can be caused by narrowing of the arterial lumen, arteritis, cervical compression and other factors. The otogenic vertigo caused by ear lesions is more obvious in terms of sky spinning, nausea, vomiting, tinnitus and deafness, while vertigo caused by other causes can have different degrees of vertigo, but often without the feeling of sky spinning, and usually without hearing loss and tinnitus. The following methods can help us to find the causes of vertigo: 1. To find out the triggering factors of vertigo attacks, such as the presence of acute infection, otitis media, traumatic brain injury, cardiovascular disease, serious liver and kidney disease, history of diabetes mellitus, and the presence of triggering factors such as travel by car, boat, and medication. 2.According to the characteristics of vertigo The time of vertigo attack, the trigger, the course of the disease, and whether there are recurrent characteristics. 3.Concomitant symptoms during vertigo attack: whether there is fever, sweating, tinnitus, hearing change, vision change, nausea, vomiting, numbness around the mouth and|extremities, balance disorder, etc. Only when the cause of vertigo is found can we prescribe the right medicine for different causes.
