I suddenly feel dizzy, what's going on?

In our daily life, everyone must have experienced sudden dizziness, and this feeling is quite common. We need to pay special attention to this situation. It may be a precursor to some brain disease or caused by anemia, low blood pressure, etc., which has a great impact on our lives. We need to actively understand and treat it. Here we will explain what causes sudden dizziness.

There are two possibilities: 1. Temporary brain hypoxia... Generally speaking, this is not a problem. Just some anemia. When you stand up after waking up, sitting or squatting for a long time, you may suddenly feel dizzy. In mild cases, you may only be dizzy for a few seconds before recovering, but in severe cases, you may become severely dizzy and lose consciousness, causing you to fall and potentially cause brain or body injuries. Why is it that some people can stand up easily without any difficulty, while others may suffer physical discomfort or even injury? In fact, this is related to your physical health. As long as your body circulation is good, this situation will not easily occur. As for those who already have postural hypotension, there is no need to be too nervous. As long as they develop the habit of not changing positions immediately, they can avoid discomfort or injury.

Understanding the causes of postural hypotension When we change from lying, sitting or squatting to standing up, the posture looks simple, but it requires coordination and cooperation of various organs of the body, including the heart, blood vessels, nerves, etc., to accomplish the task of standing up smoothly. When the body wants to stand up, the heart must deliver enough blood through the blood vessels to the brain, which is located at the highest point. At this time, the blood vessels must be coordinated by the nervous system to appropriately reduce their diameter so that the blood can be delivered higher and farther.

How to prevent postural hypotension? 1. "Flex your muscles and bones" before changing posture. Whether you are getting up after waking up, or standing up after sitting or squatting for a long time, you should warm up and activate your muscles and bones before changing posture to avoid postural hypotension.

For example: straighten your right foot and then bend it, do it alternately five times, then switch to the left foot; then stretch both feet together, and then slowly sit up; stay for five to ten seconds and then stand up. After standing up, do not walk immediately. Make sure you do not feel dizzy before you start walking. 2. Exercise more and get enough sleep. Since the occurrence of postural hypotension is related to poor blood circulation, as long as you move more often, you can not only make your muscles and bones flexible, but also prevent nerve aging. For example: swimming, jogging, and gymnastics are all good exercises. In addition, going to bed early and getting up early is also an important way to keep your body healthy and your metabolism normal. As long as you pay attention to these two points, I believe that not only will postural hypotension rarely visit you, but your body will also become more resistant.

Reminder: Postural hypotension is not a disease, but it makes people feel sad and "dizzy" from time to time! Especially in an era when white-collar workers make up the majority, more and more people "sit" from work to get off work every day, go home after get off work and continue to "sit" until bedtime, and then "lie down" and sleep until dawn! This lack of exercise in life makes many young people easily tired and prone to diseases that should occur in old age, postural hypotension being one of them. So, on weekends, I suggest you turn off the TV, shut down your computer, change into some comfortable clothes, and go out for a walk with your whole family!

This is not only good for health, but also very helpful for family and parent-child interactions! 2 is postural hypotension. It means that changes in body position have a certain impact on blood pressure. When squatting or sitting, the height difference between the highest point of the human body (brain) and the lowest point (foot) is small, and the heart automatically adjusts its blood pumping force to an appropriate level, which can ensure that the blood is pressed to the height of the brain, thereby ensuring blood supply to the brain. However, when you stand up suddenly, the height of the brain rises significantly. At this time, the heart's blood pumping force cannot be adjusted to the appropriate force in time, resulting in a brief lack of blood flow to the brain, causing dizziness. Different people have different physical conditions, and the same principle also manifests itself differently in different people, so there are situations such as "white vision, weakness in limbs, and sometimes fainting" as you mentioned.

For healthy people, this situation is normal, and the best solution is to increase exercise. If you have other diseases, especially cardiovascular and cerebrovascular diseases, you have to go to the hospital for specialized treatment.
