Ms. Li, 63, has been unable to sleep well recently. As soon as she turned over, she felt dizzy. She didn't care. Unexpectedly, her symptoms became more and more serious. After going to the hospital for examination, I found that the "real killer" who caused my dizziness was a disease called otolith. June 9 is "China vertigo Prevention Day". Experts suggest that "dizziness" may also be a disease, and dizziness and dizziness are two different concepts. It is important to clarify the duration and specific manifestations of "dizziness" during treatment, which plays an important role in disease diagnosis. Many people have experienced dizziness and dizziness. Jiang Yang, chief physician of the third Department of Neurology of Shenyang First People's Hospital, introduced that vertigo and dizziness are two concepts, and their symptoms and countermeasures are different. "Dizziness is sometimes called dizziness. It is a symptom of discomfort in the head that cannot be accurately expressed. It can be manifested as a slight sense of instability, floating, and movement. It is usually caused by diseases such as hypotension, cerebral ischemia, and hypoglycemia." Jiang Yang said that vertigo is a kind of motion illusion. There is no external stimulation at the time of onset. It can be manifested as rotation, rolling, rocking, dumping and bumping. Some types of vertigo may also have tinnitus or fullness of ears before the onset. "Patients should describe their symptoms as accurately as possible, which is conducive to doctors' judgment and better suit the remedy to the case." What should we do when "dizzy"? Experts pointed out that the words "stop, rescue and stabilize" should be kept in mind. That is, immediately slow down or stop the ongoing activities. If the symptoms are serious, seek the help of friends and family members, try to lower the center of gravity, maintain the sitting, lying or lying down position, and reduce the occurrence of falls. Experts remind that "dizziness" may seem like a small thing, but it may lead to serious consequences. To explore the diseases that cause "dizziness", accurate diagnosis and treatment, detailed physical examination and auxiliary examination are essential. Therefore, once we have dizziness or dizziness, we should go to the hospital in time to avoid delaying the condition. (outlook new era)
