In life, many people have such experience, squatting and then stand up when the eyes suddenly black. Some people are very scared and think that they may have some diseases. So, what's going on when you stand up and get dark? What should you do?
Why stand up in front of suddenly black
There are two kinds of black eyes when you stand up
1、 Is anemia, generally squatting suddenly stand up will be black eyes, dizziness, if it is sitting will be anemia is more serious. So we need to get blood as soon as possible.
2、 It's a spinal problem. It's possible that the vertebral bone will proliferate, which will compress the nerves and cause hypoxia in the brain. But generally, spinal problems are rare among young people. In the past, they used to get diseases only after middle age. But now this kind of disease is much earlier than before. Many 25-year-old office workers begin to have this kind of disease, which is mainly caused by long-term exposure to computers and lack of exercise.
The occurrence of this phenomenon is called 'transient cerebral ischemia' in medicine. People's brain and eyes are most sensitive to ischemia, as long as ischemia 1-2 seconds can appear dizzy symptoms. In daily life, because of the change of body position, sometimes it will cause the fluctuation of blood pressure, which directly affects the change of blood flow. Fortunately, our body has a set of special mechanisms to stabilize blood pressure, that is, in the most obvious place of human carotid artery pulsation, there is a chemical receptor in the carotid sinus, which can regulate the speed of heart beat and the level of blood pressure. It plays an important role in the blood circulation of the whole body, especially in the brain. Under normal circumstances, the human body maintains the stability of blood pressure by the regulation of receptors. But some people because of the slow and weak regulation of the receptor, when squatting for a long time and suddenly stand up, when the position changes, it will be temporarily reduced due to blood pressure and cause eye black. This phenomenon is common in anemia, hypotension and autonomic nerve dysfunction and lack of physical exercise. The preventive method is not to stand up suddenly when squatting, but to stand up slowly. In addition, usually to participate in sports activities, in order to enhance the physique.
