Why does it feel like I m about to faint every time I squat down and then stand up?

Many people have this experience: after squatting for a long time and then standing up suddenly, they will feel dizzy and dark. 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 violently, 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.

Ordinary people will be like this, but people with anemia are slightly more serious, remember, when squatting, the blood supply will be less than the brain, standing violently, will make the head itch and ischemia, resulting in a little dizzy symptoms, you should pay more attention in the future, stand up slowly, this symptom will be less, thank you.

Sub-health. You definitely have low blood pressure.

Anaemia. This is really hard to treat.

Easy to fall. Knowing more about the Great Movement.

There are advantages of erection of molds. Beg.

Insufficient blood supply to the brain leads to dizziness caused by lack of oxygen to the brain.

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 wide spine and brain will not get enough oxygen and nutrients for a while.

The conclusion is that most of the phenomenon of Shenling is a normal phenomenon and is not caused by anemia.
