After squatting for a long time, I stand up and see gold stars. Is it anemia or low blood sugar? The real reason is probably
Many people find that they have been squatting for too long, and when they suddenly stand up, they will feel dizzy, their eyes will turn black, as if they are about to faint, and their legs and feet will be numb.
When this phenomenon occurs, many people think that they are anemia or hypoglycemia, and they are not at ease.
After squatting for a long time, I suddenly stand up and see gold stars. Is it anemia or low blood sugar? The real reason is probably
normal physiological phenomenon
The normal physiological phenomenon is that after squatting for a long time, suddenly standing up will cause black eyes or dizziness.
Because when we squat, it will compress the blood vessels of the lower body. The longer we squat, the more severe the hypoxia of the brain and upper body.
When you stand 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 jerking high-pressure stimulation can cause a brief dizziness, but it doesn't last very long.
Because the regulation of blood pressure is very fast, the body will return to normal immediately. This is not due to 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 have been squatting for a long time, you must be slower when you stand up. You can stand up slowly while holding 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, which is caused by the posture of the human body, not caused by pathological changes. It is also called orthostatic hypotension.
Because squatting for too long, blood cannot circulate up and down very well, and blood pressure cannot be recovered in a short time. When standing up, the compression of blood vessels in the lower extremities is relieved, and the blood of the whole body flows quickly to the waist, which can easily cause orthostatic low blood pressure.
The blood pressure of the brain drops instantly, which will cause blackness in front of the eyes, or serious dizziness, and the phenomenon of gold stars appearing in front of the eyes.
The difference between orthostatic hypotension and hypoglycemia, anemia
Hypoglycemia is the reduction of sugar in the blood, which can be caused by high-intensity physical work and irregular eating and eating too little. 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, 15% of orthostatic hypotension occurs after the age of 65, and 30% to 50% after the age of 75.
Usually pay attention to add more water, because the body's water is sufficient, the speed of blood circulation will 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, don't panic when orthostatic hypotension occurs, because it is easy to lose the center and fall.
Calm down and lower your weight. If your clothes are too tight, you can loosen the buttons first to help your body recover.
After recovering, get up slowly, you can hold things in your hands and stand up slowly. So, squat for too long, don't stand up suddenly, especially the elderly.
blocked blood vessels
Under the premise of no other diseases, if you often squat down and stand up suddenly, you will experience dizziness or gold stars in your eyes, which may be caused by blocked blood vessels or too thick blood.
Because when you get up, blood pressure rises. If there is a blockage in the blood vessels in the brain, there will be insufficient blood supply to the brain, ischemia and hypoxia, and dizziness or dark eyes.
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 vegetables and fruits, reduce blood viscosity, speed up blood circulation, and ensure blood supply and oxygen supply to various organs.
Appropriate fitness exercise can also speed up blood circulation, expel toxins from the body, and also play a role in reducing blood viscosity. Lowering blood cholesterol and triglyceride levels and exercising are beneficial.
It often occurs that the eyes become dark when squatting for too long, or there is a gold star in front of the eyes. You need to pay attention to the changes in your body. If there is no improvement for a long time, you should go to the hospital for medical treatment in time to avoid more serious symptoms.
