I felt dizzy and black in front of my eyes when I stood up

Perhaps everyone has had this experience, that is, after squatting and standing up, you will experience black spots in front of your eyes and dizziness. Don’t underestimate this situation. Not to mention that it may be a precursor to some brain diseases. If we experience black spots in front of our eyes and dizziness on the roadside, it is easy to cause a traffic accident and endanger our lives. We need to understand and treat it in time. So why do we see black spots and feel dizzy when we stand up from squatting?

The dizziness you feel when you stand up is mostly caused by transient hypotension. Because you stand up quickly, the blood has not reached your head yet, and the brain suffers from ischemia and hypoxia. This is more common in young people, especially in summer and after defecation. It is not necessarily related to anemia. You should pay attention to improving your nutrition and eat more protein-rich foods. Stand up slowly and stand for a while before moving.

Precautions for self-treatment of hypotension:

(1) This disease falls into the category of asthenia, so it is advisable to regulate the whole body. Drug treatment alone is not effective.

(2) Actively participate in physical exercise to improve physical fitness. The amount of exercise should be increased gradually, not too hastily, but persistently.

(3) If you feel dizzy or even faint when getting up, you should move your limbs slightly, rub your face, and massage your abdomen before getting up. When getting up, sit for a while, then slowly get out of bed and stand. The foot section of the bed should be slightly elevated.

(4) Live a regular life and eat a nutritious diet. In normal times, you can eat more foods that warm the spleen and kidneys and raise the yang energy, such as venison, dog meat, mutton, rooster, wine, pepper, chili, ginger, leek, longan, strong tea, coffee, etc.

(5) Drink more water, eat more soup, and consume slightly more salt than the average person every day. Eat less winter melon, watermelon, gourd, red bean, etc.

This is because the blood supply pressure to the brain is relatively low when sitting or squatting for a long time, and the blood supply pressure required when standing up suddenly increases instantly. However, the temporary lack of blood supply will cause dizziness, blacking out, etc. Guidance:

Guidance: Don't worry too much about your situation. When standing up, move slowly, not too quickly. Strengthen your nutrition, eat more vegetables and fruits, and actively exercise to improve your physical fitness.

When people stand up after squatting, it is easy for the body's blood to not be supplied to the brain in time, causing short-term ischemia of the brain and certain symptoms of insufficient blood supply to the brain, such as dizziness and black spots in front of the eyes. If you stand up too quickly, you may fall. This situation is a normal physiological phenomenon called orthostatic hypotension.

Guidance:

This situation is a normal physiological phenomenon and you don't need to be too nervous. It is recommended that you move slowly when you get up in your daily life, and this situation will gradually disappear.

When we want to change from lying, sitting or squatting to standing up, the posture looks simple, but it requires the coordination and cooperation of various organs of the body, including the heart, blood vessels, nerves, etc., to accomplish the task of standing up smoothly.

When the body wants to stand up, the heart must deliver enough blood through the blood vessels to the brain, which is located at the highest point. At this time, the blood vessels must be coordinated by the nervous system to appropriately reduce their diameter so that the blood can be delivered higher and farther. However, if these organs react too slowly or are unable to perform this function, the brain will experience temporary hypoxia, causing dizziness or fainting, which is called "postural hypotension."

Good target

Although postural hypotension is not a highly contagious disease like the common cold, according to clinical observations by doctors, more than half of the people in the country have experienced postural hypotension, with women being the majority. If divided by age, the elderly have more than the young, and the others are pregnant women.

From this we can see that this is related to the human body's nerve response and blood circulation. Generally speaking, men have better blood circulation than women; and young people have better blood circulation than old people; as for pregnant women, most of them are in the middle and late stages of pregnancy, because the fetus grows bigger, which makes the blood circulation in the lower body poor.
