Vertigo is one of the most common symptoms among patients, and patients feel very painful when they have an attack and turn around to seek treatment. However, most patients do not know much about vertigo, and even have many misunderstandings. We hope to help you get the right number of vertigo, so that you can better cooperate with the diagnosis and treatment and recover your health as soon as possible. 1.What is vertigo? ”Vertigo is a subjective illusion caused by people’s spatial orientation disorder. When the attack occurs, you can see things spinning with your eyes open; you can feel yourself spinning with your eyes closed, and you can also have a sense of shaking, floating and lifting. Many patients also have nausea, vomiting, sweating, and even fall down. 2.Is vertigo the same thing as dizziness and lightheadedness? Dizziness” or “lightheadedness” is a feeling of dizziness in the head, where the patient feels “lightheaded” and “light-headed”. When you feel dizzy, you don’t feel like you are spinning around and you don’t fall down suddenly. ”Vertigo” and “dizziness” are not exactly the same thing, but sometimes it is difficult to separate them. 3.Why do I feel dizzy? The human body relies on the coordination of three systems: the ears (vestibular part of the inner ear), the eyes (vision), and the legs and feet (proprioception of muscles and joints) to maintain balance, with the vestibular system being the most important. If there is damage to the vestibule, vertigo, unstable walking or even falls can occur. This is also the reason why some vertigo patients also have hearing loss, tinnitus and stuffy ears, so many vertigo patients often have to undergo hearing and vestibular examinations. 4.Does vertigo have to be caused by insufficient blood supply to the brain or cervical spondylosis?

There are dozens of diseases that can cause vertigo. Medically, vertigo can be divided into two categories, peripheral and central, according to the location of the disease. Peripheral vertigo is caused by lesions of the inner ear or vestibular nerve, such as benign paroxysmal positional vertigo (BPPV), also known as otoliths, Meniere’s disease, vestibular neuritis, etc. Central vertigo is mainly a disease of the brainstem, cerebellum or brain, with infection, inflammation, vascular disease, tumors, etc. as possible causes. Peripheral vertigo disorders are more common, accounting for about two-thirds of vertigo.
