Why do I get momentary dizziness and loss of consciousness after squatting for a long time?

It may be the problem of anemia, or it may be that the constitution is relatively weak, because after squatting for a long time, it is possible that the blood cannot be replenished to the brain in time, so the brain is somewhat ischemia.

Normal. Generally, people will get dizzy when they squat down and stand up again. It's a matter of physical pressure.

This is not normal, it is possible that you are anemic, it may be malnutrition, and you must eat more red dates at ordinary times.

This is normal, because squatting for too long will cause blood circulation to be blocked. This results in an inadequate blood supply to the brain. This is what happens.

The main reason for this phenomenon is temporary anemia in the brain.

When a person is squatting, the waist and legs are twisted and turned, and the blood cannot flow up and down. If you stand up suddenly at this time, the blood will flow down quickly, resulting in local ischemia in the upper body, but the brain and eyes have particularly strict requirements for oxygen and nutrients, and they must not be slackened. If you are already weak, the situation is more serious.

However, don't panic when this happens, and you don't have to go to the hospital. If the blood supply to the head is insufficient, the heart will immediately work hard to pump blood up, and it will not take long for the body to return to normal. Of course, when standing up, don't move too hard, try as slowly as possible, so that the blood does not flow too violently, and the blood supply to the heart can keep up, and this phenomenon will not occur.

Because after squatting for a long time, part of the blood in the lower limbs does not circulate, and the lower limbs are in a state of hypoxia. When a person stands up, the blood valve of the lower limbs is suddenly opened, and the blood flows rapidly, resulting in no time to ventilate the body, and the blood containing carbon dioxide enters the brain. Just take a little rest.

Because the blood is under downward pressure when a person is squatting, if you stand up immediately, due to the lack of blood in the brain, it will be in a state of cerebral hypoxia for a short time, which will affect the optic nerve, so dizziness and blurred vision will occur. It doesn't matter, it's a physiological phenomenon, as long as you don't squat or stand too fast, it will feel different!

When a person is in a squatting position, the lower limbs are flexed, and the blood vessels of the lower limbs are compressed so that the blood is not easy to flow to the lower limbs, and the lower limbs appear to be ischemia. When a person who has been squatting for a long time suddenly stands up, the blood vessels of the lower limbs are restored to unblocked, and at this time, it is like suddenly opening the floodgates, and the blood will rush to the lower limbs in large quantities, so that the head will not have enough blood, and the brain will not get enough oxygen and nutrition for a while. The conclusion is:

Most of this phenomenon is a normal phenomenon and is not caused by anemia. Reminder: 1. It is best not to squat for a long time for people with this phenomenon, if you have to squat often due to work, you can prepare a low stool in advance to reduce the degree of flexion of the lower limbs; 2. When standing up after squatting for a long time, it is advisable to stand up slowly to reduce the discomfort caused by this; Care should even be taken to clean up the work site to prevent injuries after a brief loss of consciousness and a fall to the ground.

3. It is advisable to participate in more physical exercise to enhance cardiovascular function. Why do people get dizzy when they stand up after squatting for a long time? If you squat on the ground for a little longer, and when you stand up suddenly, you often feel the world spinning and your eyes are full of stars.

This is caused by temporary anemia of the head. When a person is squatting, there are some special cases for the distribution of blood in the body. The first is that the two legs are pressed very tightly, the blood vessels are flattened, and the blood reaching the lower limbs is relatively small; Secondly, because the head is slightly tilted forward when squatting, the blood to the head is relatively more distributed.

When you stand up suddenly, the blood vessels in the lower limbs suddenly release the compression, so a significant part of the blood flows to the lower half of the body. In addition, blood also has a certain weight in the body, and when you stand up suddenly, the blood flow will also flow to the lower half of the body due to the attraction of gravity and inertia, and the blood distributed to the upper body will be reduced. In addition, when standing up, the head is also upright, and it is more difficult to spurt blood from the heart to the high head.

All of this results in a relative decrease in blood flow to the head. The human brain is the most in need of blood oxygen, and a temporary reduction in blood supply can make people feel dizzy due to temporary cerebral anemia. In addition, due to the decrease in blood in the head, the blood supply to the eyeballs is naturally less, so the phenomenon of dazzling and Venus will occur.

At the same time, anemia and hypoglycemia can aggravate this phenomenon.

I also have this situation, not necessarily caused by anemia, after squatting up, the blood can not be timely ** The blood volume of the brain will be like this, it's okay, just exercise more!

Whoever squats for a long time is like this, every time my school runs after a step, the teacher says don't squat, or do squatting, you will get dizzy.

This is because of anemia, so there will be the problem you said, usually pay attention to your diet, exercise more, it will be fine, no big problem!

Eh, I'm severely anemic.

Eat more raw blood.

There is also supplemental nutrition.

If your blood sugar is low, you should usually drink more beef or chicken stewed soup to replenish it, eat a few jujubes a day, and stick to it for some days.
