Why do I feel dizzy and black in front of my eyes after squatting for a long time?

This symptom is called orthostatic hypotension. Many people have this experience, after squatting for a long time and then standing up suddenly, they will feel dizzy and black. The main reason for this phenomenon is temporary anemia in the brain.

When people squat, the waist and legs are bent, the blood can not go up and down, if you stand up at this time, the blood will flow down quickly, resulting in local ischemia of the upper body, but the brain and eyes have particularly strict requirements for oxygen and nutrients, and they must not be slackened at all. If the body is already weak, the situation will be more serious. However, don't panic when this happens, you don't have to go to the hospital, the blood supply to the head is insufficient, the heart will immediately work hard, busy pumping blood, and it won't take long for the human body to return to normal.

Of course, be careful not to move too violently when standing up, 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.

When a person is squatting, the lower limbs are flexed. At this time, the blood vessels of the lower limbs are compressed, and the blood is not easy to flow to the lower limbs, and the lower limbs will be in a slight ischemic state, and they will feel numb after a long time. When you suddenly stand up after squatting for a long time, the blood vessels in the lower limbs suddenly return to unblocked, as if the floodgates have been opened suddenly, and a large amount of blood will rush to the lower limbs.

The amount of blood produced by a person in a certain period of time is certain, and a large amount of blood rushes to the lower limbs, so that the blood in the head is not enough, and the brain does not get enough oxygen and nutrients for a while, so most people will have dizziness, heartbeat, and black vision. After the body adapts and adjusts, this phenomenon disappears quickly in most people. Therefore, most of this phenomenon is a normal physiological phenomenon, and it is not a disease such as anemia.

As soon as I stood up, my blood pressure was still in the state of sitting, and I couldn't reach the high blood pressure when I was standing The brain is not enough to educate So the eyes are black Many cases are symptoms of anemia, if you have had this situation since you were a child I see you go to the hospital for a routine blood test Usually after you squat, slow down, you won't get dizzy I don't know how old you are? If you go to the hospital to check the blood routine, I also see that you go to the orthopedic department and ask the doctor to help you check the cervical spine (whether the cricoaxial joint is out of alignment), if so, it will also cause dizziness when standing up.

As soon as I stood up, my blood pressure was still in the state of sitting, and I couldn't reach the high blood pressure I had when I was standing, and my brain was not able to learn enough.

So the eyes are black. A lot of the cases are symptoms of anemia, and if you've had this since you were a child, I would like you to go to the hospital for a routine blood test

Usually after you squat, slow down, you won't get dizzy

I wonder how old you are?

If you go to the hospital to check the blood routine, I also see that you go to the orthopedic department and ask the doctor to help you check the cervical spine (whether the cricoaxial joint is out of alignment), if so, it will also cause dizziness when standing up.

Hehe, it's not a disease. Don't worry. 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 that this phenomenon is mostly a normal phenomenon and is not caused by anemia.

It's okay, you don't get sick, but when you suddenly stand up, the blood can't circulate to the brain for a while, and there will be temporary dizziness and dizziness... Just take your time. You also have to pay a lot of attention.

If your blood pressure is fine, then this is a normal phenomenon, because when people squat for a long time, the blood is mainly concentrated in the lower limbs, and when you suddenly stand up, the blood cannot circulate to the brain for a while, and there will be temporary dizziness and dizziness.

Many people will be like this, because squatting, the blood supply to the brain will be insufficient, so when you get up, you will be dizzy, black in front of your eyes, if there are no special signs, you don't care too much.

Pay more attention to physical activity and rest well

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.

If you stand up suddenly, your blood pressure will not rush up all of a sudden, which will cause dizziness and even vomiting, so you must stand up slowly after squatting for a long time.

When squatting, the blood circulation in the human body is not smooth, and when you get up, you will be dizzy, and there is also one reason for anemia, so you should eat more pork liver

Dizziness and black eyes after standing up after squatting for a long time may be these two reasons.
