”Dizziness” should be a symptom that everyone may have experienced in their lifetime, many people think it is a minor problem, not a big problem, and people may casually say “Oh, I haven’t rested well in the past two days, I’m a little dizzy” when chatting in general. Of course, the majority of dizziness is probably caused by lack of rest or exertion, and will be relieved by rest on its own, and will not have serious consequences. You may feel dizzy when you are hungry, dizzy before and after your period, or dizzy when you stand up suddenly after squatting for a long time. Occasional dizziness or dizziness due to a change in position is not a big problem and should not be a major concern. However, some dizziness is often a precursor to some diseases that may have serious consequences. Today we will decipher these “dizziness” that may be a precursor to diseases that can cause serious harm to our bodies. First of all, we need to understand what is dizziness? What are the uncomfortable sensations of dizziness? Dizziness is a broad concept that includes both dizziness (dizziness), which is also known as non-vertigo, and vertigo. Many people will treat dizziness and vertigo as the same thing, but in fact, there is a difference between dizziness and vertigo. The medical term for the conscious sensation of dizziness includes the sensations of dizziness, head swelling, light-headedness, shaking in the brain, and blurred eyes. In contrast, dizziness is a more specialized symptom, which is characterized by motion illusion or hallucination. The conscious sensation is mainly the feeling of tilting, or the feeling of shaking oneself or rotating the surrounding objects. When you open your eyes, you feel that the objects around you are spinning, and when you close your eyes, you feel that you are spinning, and it is accompanied by nausea, vomiting, cold sweat, panic, and even increased bowel movements and the feeling of wanting to go to the bathroom. Vertigo is the most common type of dizziness that doctors encounter in their daily work. In some cases, vertigo has a sudden onset and recurrence, which affects daily life and can lead to anxiety, depression and other illnesses over time. What part of the human body determines the dizziness that people feel? Let’s briefly understand that people feel dizzy mainly because there is a problem with the body’s system of balance management itself or other related systems that affect the feeling of balance, which includes the vestibular system, vision, and proprioceptive balance triad. will feel dizzy. The coordinated operation of this system requires the central control of the brain, so it can be divided into peripheral vertigo and central vertigo depending on the problem area. What diseases can cause dizziness? What are the serious consequences? There are a lot of diseases that can cause dizziness, but the most common ones in clinical work are peripheral vertigo, which are mostly caused by lesions of the vestibular system in the ear: 1, Meniere’s disease: mostly in middle-aged people, with no obvious cause before the attack. The main manifestations are sudden onset vertigo, progressive deafness, and tinnitus to be considered for this disease. Secondly, there is also vestibular neuronitis: it generally manifests itself as sudden vertigo and malignancy after a cold, vomiting, panic, sweating, etc. There is no hearing loss, and most of them do not need treatment for about six weeks to heal themselves; 2. Benign positional vertigo: this disease is predominantly female, and the vertigo occurs when the patient’s head is in a special position and lasts about half a minute, accompanied by panic, sweating and nystagmus. This kind of dizziness can be cured by itself, but some frequent attacks need to be treated by otolith repositioning; 3. Central vertigo: including cerebrovascular diseases, intracranial occupying lesions, inflammation, etc.; 4. Cerebrovascular diseases: vertebrobasilar artery lesions are the most common causes of dizziness, and these organs related to balance are mainly supplied with blood by vertebrobasilar artery, so if vertebrobasilar artery lesions occur, these organs or nerve tissues will become ischemic and dizziness will occur. If the vertebrobasilar artery is diseased, dizziness will result from the lack of blood to these organs or nerve tissue. Any lesion that affects the blood flow in the vertebrobasilar artery can cause dizziness, the most common of which is atherosclerosis leading to narrowing or occlusion of the blood vessels, which often occurs in the elderly. This type of dizziness usually lasts for a long time, has milder conscious symptoms, and is usually not accompanied by symptoms such as malignancy, vomiting, panic, or sweating. However, it is often accompanied by other symptoms of ischemia in the blood supply area of the vertebrobasilar artery, such as blurred vision, black haze, flashing light, double vision, distortion of vision, pain in the ear, discomfort in the throat, numbness of the face and limbs, headache, and sudden collapse. We know that the most important part of the human brain center is supplied by the vertebrobasilar artery, so dizziness from lesions in this area often suggests the risk of further serious cerebral infarction; 5, cervicogenic dizziness: as the name implies, dizziness is triggered by lesions in the cervical spine.
