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.

Check your blood pressure first, below 90 60 is low blood pressure. Pay attention to diet and nourish qi. Eat more raw peanuts and soak astragalus to drink.
Check the blood routine again to see if the red blood cells and hemoglobin are normal, and eat more animal livers such as pig liver.
It could be anemia, low blood pressure!
After squatting down and standing up, the blood cannot deliver oxygen to the brain in time, resulting in a temporary lack of oxygen!
Generally, normal people will also have this situation, so I can only say that I am willing but not sure!
If you really feel that you are anemic, it is recommended to go to a major hospital for a check-up.
The online answer is not a standard answer, the body is important, please check it in time, and exercise at the same time is indispensable, more exercise can enhance the physique, but not overexercise.
Good health.

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.

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

1. All When a person is squatting, the waist and legs are tortuous, and the blood cannot go up and down. If you stand up abruptly at this time, the blood will flow down quickly due to gravity, resulting in local ischemia in the upper body, but the brain and eyes have particularly strict requirements for oxygen and nutrients. If you are already weak, the situation is more serious.
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.
If you don't move violently but still have the above symptoms frequently, it is best to go to the hospital to check for anemia or hypoglycemia.
Attached: Self-test of anemia symptoms.
Check your physical condition, if you find more than 3 symptoms, you may have anemia:
1. Recently, I often feel tired easily, and even weak.

9. Longitudinal white lines appear on the nails.
10. There are often small wounds, cracks or lack of blood gas around the mouth.
11. Irritability.
12. Oral pain.
Standing up suddenly will cause the brain to be instantly insufficient, and you will be a little dizzy, and you will not have this situation if you stand up slowly.
This is a temporary cerebral insufficiency. When you squat down, the lower limbs will be flexed, and the blood vessels in the lower limbs will be pressed so that the blood will not be easy to flow to the lower limbs, and the lower limbs will appear to be ischemia. Also, when you stand up after squatting for a long time, the blood vessels in the lower limbs will be restored to the smooth flow, and the blood will rush to the lower limbs in large quantities, so that the blood in the head will not be enough. >>>More
