Do you have this feeling in life? I squatted and brushed my shoes, selected vegetables, planted vegetables, etc. Whether I suddenly stood up, I would feel dizzy and had dark symptoms in front of me, as if I was about to faint in the next second.
Many people will have this symptom, so everyone thinks that this symptom is normal. Women are anemia, men are tired, but no one thinks that this may also be a sign of the body's illness. I feel dizzy and dark after squatting for a long time. The reason may not be as simple as you think.
What is the principle of dizziness and darkness when standing up after squatting for a long time?
The reason why people feel dizzy is because when people squat down, their body posture will change, and the blood vessels and muscles on their legs will be compressed due to the weight of the entire body. In this way, the blood circulation of will be hindered and the flow rate will slow down.
When the body suddenly stands up, the pressure on the blood vessels is relieved and affected by gravity. At this time, The blood will flow to the legs in large quantities, which will lead to cerebral ischemia.
In fact, the brain responds first, and then the body's mechanism to regulate blood pressure will receive signals from the brain, and then quickly regulate blood pressure according to changes in the body's posture. The intermediate regulation mechanism is not as fast as the brain, many people will feel dizzy and dark, but it will be relieved in a while. For this kind of phenomenon that can stand up quickly, there is also a medical name - orthostatic hypotension .
How to avoid orthostatic hypotension after getting up?
Like Hypertension , the blood pressure itself is unstable. Even if you are normal in your day, the blood pressure will change. If your blood pressure is too low, it is not a good thing, and it is even more unfavorable for the condition. There is also the elderly who are older, their blood pressure fluctuations will also be relatively large. It is recommended that these two types of people lie down or squat, and they should not be recommended to get up too fast. slowly get up . For example, When you wake up in the morning, you can wait in bed before you wake up before getting up to prevent dizziness. You should also take regular blood pressure measurements. If you find obvious abnormalities in your blood pressure, it is best to seek medical treatment in time.
Of course, if you want to avoid this phenomenon, you must avoid it from the source, that is, squat less and avoid blood vessels being compressed. For example, when squatting in the pit and going to the toilet, don’t use your phone to read newspapers. The longer the time, the more blood will be missing in the brain. mild symptoms include dizziness and darkness, and severe symptoms may cause fainting on the spot.
When you stand up, it is best to slowly give the blood pressure regulation mechanism a buffer time. Of course, it is not to make you slow and as if you are loaded with a bomb, but to make you change your posture. For example, let stretch your legs in advance to relax your blood vessels and muscles . Avoid ischemia on both legs and let the body's blood flow into the blood vessels, and then slowly get up after for about 20 seconds to move your body.
So is this phenomenon related to anemia and heart disease?
Dizziness and darkness are indeed symptoms of anemia, but it may not be caused by anemia. If you have this symptoms only once or twice, it may be due to orthostatic hypotension, but if you have skin opposition, you will also have symptoms of dizziness, and you will also have symptoms of , which are accompanied by symptoms of , tinnitus, , and lack of appetite. It may not be due to orthostatic hypotension, but why is it because of anemia in the body? It is best to go to the hospital for a regular blood test to see if the amount of hemoglobin in the body is sufficient.
There is a heart problem, is it the same?
Cardiovascular doctors said this kind of dizziness and dizziness. They called Black swelling . The reason for black scum is not just because the body suddenly stands up, the brain is insufficient for .
There are also other reasons, such as cardiac arrhythmia, whether the heartbeats fast or too slow, which will affect the work of the heart. It is impossible to transmit fresh blood to the whole body in time, and the brain is above the heart, which will lead to insufficient blood supply to the brain. But at the same time, the body will also be accompanied by symptoms of hands and feet weakness.
From this we can see that if there is any abnormality in the body, do not ignore it. This may be a signal of the body's illness. No matter how common the symptoms are, you need to be vigilant.

In addition to the animal liver, there are also various lean meat , which does not have any fat in it. There are also egg yolks and animal blood. Although it contains iron, it does not contain pork liver, lean meat, etc. and are easily absorbed by the body.
In addition to animal food, there are also plant foods, such as soybeans and soy products , which has a higher body absorption rate than rice and noodles. There is also sesame paste , which contains twice the iron element of pork, and also contains a lot of other nutrients.
In addition to sesame paste, some people will feel a little bit greasy, but they are also fresh like fungus , mushroom and other vegetables. contains as many as 185 mg of iron for every 100 grams of . If you don’t hate this kind of food, you can eat more.
