After squatting for a long time, standing up and staring at gold stars, is it anemia or hypoglycemia? The real reason is mostly it
Many people find that after squatting for too long, they will feel dizzy when they stand up suddenly, their eyes will turn black, as if they are about to faint, and their legs and feet will still be numb.
When this phenomenon occurs, many people think whether they are anemic or hypoglycemic, and they are not at ease.
After squatting for a long time, I suddenly stand up and see stars. Is it anemia or hypoglycemia? The real reason is mostly it
normal physiological phenomenon
It is a normal physiological phenomenon that after squatting for a long time, when you stand up suddenly, your eyes will become dark or dizzy.
Because when we squat, we will compress the blood vessels in the lower body. The longer we squat, the more serious the oxygen deficiency in the brain and upper body will be.
When standing up suddenly, the heart will contract strongly, so that the upper body of the person can quickly return to normal, so the blood pressure of the person suddenly rises at this time.
Our brains are very sensitive, and this kind of high-voltage stimulation will cause a short-term dizziness, but the duration will not be long.
Because the adjustment speed of blood pressure is very fast, the body will return to normal immediately. In this case, it is not caused by anemia or hypoglycemia.
How to prevent?
Now that the weather is relatively high, many people like to squat in the shade to chat. If you squat for a long time, you must stand up slowly. You can stand up slowly with something, which can reduce the stimulation to the brain and heart. Protect blood vessels, because a sudden increase in blood pressure is not good for blood vessels and the body, so people who usually like to squat can pay attention.
orthostatic hypotension
This kind of hypotension is different from pathological hypotension. It is caused by the posture of the human body, not caused by pathological changes. It is also called postural hypotension.
Because of squatting for too long, the blood cannot circulate up and down well, and the blood pressure cannot be recovered in a short time. When standing up, the compression of blood vessels in the lower limbs is relieved, and the blood in the whole body quickly flows to the waist, which is easy to cause erection. low blood pressure.
The blood pressure of the brain drops instantly, which will cause the eyes to become dark, or in severe cases, dizziness, and the phenomenon of Venus appearing in front of the eyes.
The difference between orthostatic hypotension and hypoglycemia, anemia
Hypoglycemia is the reduction of sugar in the blood, which may be caused by high-intensity physical labor, irregular diet and too little food. Anemia is a decrease in the amount of hemoglobin in the blood, and there are many types.
How to prevent orthostatic hypotension?
Orthostatic hypotension occurs in middle-aged and elderly frail people. Orthostatic hypotension occurs in 15% after the age of 65, and 30%-50% after the age of 75.
Usually pay attention to add more water, because the water in the body is sufficient, the speed of blood circulation will also be accelerated. There is also more exercise, because orthostatic hypotension generally occurs in relatively weak people, so it is very important to exercise more to improve your immunity.
In addition, when orthostatic hypotension occurs, don't panic, because it is easy to cause loss of center and fall.
Calm down and lower your center of gravity. If the clothes you wear are too tight, you can loosen the buttons first, which will help your body recover.
After recovering, stand up slowly, you can stand up slowly with your hands on things. Therefore, if you squat for too long, don't stand up suddenly, especially the elderly.
blood vessel blockage
Without any other diseases, if you often squat down and stand up suddenly, you will experience dizziness or staring at your eyes, which may be caused by blocked blood vessels or too thick blood.
Because when you get up, your blood pressure rises. If a blood vessel in the brain is blocked, there will be insufficient blood supply to the brain, ischemia and hypoxia, dizziness or black eyes will appear.
It shows that there is thrombosis in the cerebrovascular, and preventive measures need to be taken in time to reduce the probability of cerebrovascular disease.
How to prevent clogged blood vessels
Dyslipidemia is mainly related to people's bad eating habits, such as eating greasy and spicy food, which will lead to increased blood viscosity.
Therefore, you need to adjust your diet, add more water to your body, eat more fruits and vegetables, reduce blood viscosity, speed up blood circulation, and ensure blood and oxygen supply to various organs.
Appropriate fitness exercises can also speed up blood circulation, expel toxins from the body, and also have an effect on reducing blood viscosity. To lower blood cholesterol and triglyceride levels, it is good to exercise more.
It often happens that when you get up from squatting for too long, your eyes will turn black, or you will see stars in front of your eyes. You need to pay attention to the changes in your body. If you don’t improve for a long time, you should go to the hospital in time to avoid more serious symptoms.
