It was suddenly pitch black in front of me, but it took less than 1 second to recover

If you are squatting and suddenly stand up, due to the lack of oxygen in the brain, this situation will happen when you stand up suddenly, it is recommended that you exercise more, warm up more before exercise, do not maintain a posture for a long time, it is easy to cause poor blood circulation, but it is still recommended that you go to the hospital for a check-up if you can.

If it happens often, it is necessary to go to the hospital, if there is Venus, it may be anemia, but it is best to go for a check-up, it is not often 1-2 times, it may be too tired.

Retinal detachment, hehe, it is recommended that you go to the hospital for a check-up.

It may be because I have been too tired recently, this condition is caused by insufficient oxygen supply due to cerebral congestion, low blood pressure If it happens often, it is necessary to go to the hospital, if there is Venus, it may be anemia, but it is best to go for a check-up, it does not happen often 1-2 times, it may be too tired.

Maybe I'm hungry, but I must eat it early.

You may be too tired and need a break.

This is a symptom of cerebral ischemia, it is possible to maintain a position for a long time to cause the blood supply to the cerebral vertebral arteries to be affected, it is recommended that you exercise more and avoid playing computer for a long time, for a long time, it will lead to cervical spondylosis and cerebral cortex atrophy (Alzheimer's disease) when you are older.

People often encounter problems of one kind or another in their lives. A lot of people don't pay attention to these issues. But in fact, these problems are likely to be signals that the body needs to pay attention.

Some people experience sudden dizziness and dimness, but they can recover immediately. In general, what is the situation like?

The first possibility is hypoglycemia, hypotension or anemia.

Hypoglycemia, hypotension and anemia are actually harmful to the human body, especially patients with low blood pressure, if they do not pay attention in time, they are likely to faint and other problems. People with these problems usually squat down and suddenly stand up and there is a pitch black in front of them, sometimes the situation is unstable, but after a few seconds the situation gets better.

So if this happens, you should know if you have low blood sugar or low blood pressure and anemia, and if so, in time**. Patients with hypoglycemia can carry some candy with themIn this case, eating two kinds of candy will be a good relief, and patients with low blood pressure should also pay more attention to the usual time, take some drugs or eat more food according to the doctor's instructions, and patients with anemia can eat more. Iron-rich foods, it is a good way to alleviate the symptoms of anemia.

The second possibility: cerebral insufficiency.

Suddenly, I couldn't see clearly. After a while, I was able to get better, mainly due to insufficient blood supply to the brain. Cerebrovascular is a disease in itself.

The main cause is a problem with the blood vessels that supply blood. Then it is easy to cause insufficient blood supply to the brain, resulting in black eyes. If that's the case, the blackening may last longer.

Whatever the reason for this situation, we should pay attention to it in time. If the frequency of the situation is high, then we can go to the hospital for a closer examination to see what is causing it. We can also accept ** in time after we know.

Pay more attention to it. It can also make the situation better, usually go to bed early and get up early, don't stay up late, ensure enough sleep time to go out and exercise, and strengthen the body's resistance, which is also very helpful in preventing this situation.

General dizziness considers the possibility of anemia and hypoglycemia, Guidance: It is recommended that it is best to go to the hospital for a check-up, and take corresponding ** according to the results of the examination, and pay attention to rest and strengthen nutrition at present.

This condition may be caused by low blood pressure, but eye diseases such as fundus artery embolism cannot be ruled out.

It may be caused by hypotension, but it does not rule out the possibility of eye diseases, such as fundus artery embolism.

If the eyes are dark, it may be episodic. For example, heart diseases, such as arrhythmias, coronary heart disease, rheumatic heart disease, etc. Carotid arteriosclerosis stenosis, stroke, diabetes, cervical spondylosis, glaucoma, etc., may also cause amaurosis.

The main reason is caused by temporary anemia of the brain, if there is no anemia and other factors, it can be temporarily disposed of, but usually pay more attention to squatting down and try to slow down.

If you have this condition often, it is still very dangerous and may be a manifestation of cerebrovascular disease.

Sudden blackness in front of the eyes may be due to insufficient blood supply to the brain. Cerebral insufficiency is caused by a blood disorder in the brain, which causes cerebral ischemia and hypoxic changes. Patients may present with blackening of the eyes, impaired balance, and ataxia.

It generally occurs in middle-aged and elderly people, and most patients have a history of hyperlipidemia, hypertension and diabetes, which is a manifestation of cerebral atherosclerosis. Blood pressure, lipids, and blood glucose should be monitored, and ultrasonography of the blood vessels in the neck should be checked if necessary. In the case of atherosclerosis, oral administration of cibilin and ginkgo biloba drop pills can be used to improve blood circulation**.

Oral aspirin can also be used to prevent platelet aggregation**, and patients with hypertension can be treated with oral levamlodipine and amlodipine besylate to regulate blood pressure**. In diabetes, metformin and repaglinide can be used to lower glucose**. It may also be due to cerebrovascular disease such as cerebral infarction and intracerebral hemorrhage, and CT of the brain should be performed to confirm the diagnosis.

Most of these patients are middle-aged and elderly people, most of them are suddenly blackened in front of their eyes, and they will be fine later, and they can't find anything when they check their eyes, and finally find out that there is a problem with the cerebral blood vessels, resulting in insufficient blood supply to the brain and affecting their vision. For such patients, it is especially important to pay attention to whether there are some symptoms such as headache and dizziness at the same time as transient black door (sudden darkening) of vision. At the same time, if the eye lesion cannot be detected, you may wish to consider the possibility of cerebrovascular problems and undergo relevant examinations.

Also check for cervical spondylosis, if you are a regular driver for long periods of time.

Vasospasm of the internal carotid artery system or vertebrobasilar artery system of the brain can lead to transient ischemic attack (TIA) caused by insufficient blood supply to the brain. The internal carotid artery system mainly has blood flow to both lobes of the brain, and TIA can manifest as motor and sensory impairment on one side of the limb, and some people can produce aphasia. Ipsilateral monocular temporary amaurosis is characteristic of TIA.

These symptoms can be triggered by straining, laughing, and coughing. The vertebrobasilar artery is the main blood flow of the cerebellum and brainstem. The circulatory center, respiratory center, and arousal center are all located in the brainstem, so TIA occurs here, resulting in symptoms such as vertigo, diplopia, ataxia, balance disorders, swallowing, and speech disorders.

Since both sensory and motor nerves pass through the brainstem, hemiplegia and sensory impairment may occur during TIA. Sometimes people fall due to a sudden loss of tension in both lower limbs. These symptoms can be precipitated by rapid neck rotation, hyperextension, hyperflexion, and hypotension.

In addition to atherosclerosis, microthrombotic obstruction, blood composition and hemodynamic changes, cervical spondylosis is also one of the main ones.

It can also be caused by arrhythmia, which is mainly manifested as palpitation, cardiac arrest, intermittent pulse, blackness in front of the eyes, chest tightness, chest pain and even syncope, convulsions and other symptoms.

It is best to go to the hospital to make a clear diagnosis, take corresponding measures, and do not be careless.

If you return to normal in a few seconds, it will feel like you're getting up too hard. The blood supply to the brain is not available, resulting in a brief syncope. If your blood pressure is normal, it shouldn't be a blood pressure problem.

It may be anemia, anemia is a phenomenon often encountered in life, especially in women, on the one hand, because of women's physiological problems, when women's menstrual blood is excessive, it will cause women's body to be in a state of anemia, on the other hand, because of the malnutrition of the human body, the body does not get enough nutrition to cause anemia, manifested as paleness, tinnitus, insomnia and other symptoms, but also in front of the situation of blackness, to regulate the body symptomatically, so as not to aggravate the condition, not careless.

This should be anemia. Because after a night's sleep, the body is already hungry, so it is a little anemia.

Analysis: This condition may be anemia, low blood pressure, hypoglycemia, malnutrition, etc. Common symptoms of anemia include dizziness, fatigue, palpitation, shortness of breath, loss of appetite, pale mucous membranes, and flat nails. It is recommended to take medication after a detailed examination by a physician**.

Suggestions: It is recommended to go to the hospital for examinations, such as blood routine, blood sugar, trace elements, etc., and do the corresponding ** after diagnosis. Eat regularly, be nutritionally comprehensive, and avoid picky eaters. Pay attention to exercise and strengthen your physique.

Analysis: Hello, this situation is mostly due to low blood pressure and insufficient local cerebral blood supply.

Guidance: If frequent attacks are recommended, it is recommended to actively go to the hospital to check for lack of coarseness, and then treat the symptoms**It is better to dismantle the dressing room, usually pay attention to supplementing nutrition and water, avoid staying up late and overwork, and you can take some drugs to supplement qi and blood appropriately for prevention**.

You certainly didn't do it while you were staying, which proves that you either have a bad heart or high blood pressure, or you lack exercise and have low physical function. The recommendations are as follows:

1. Exercise more, and it will get better slowly.

2. Conditioning and health.

3. Adjust the work and rest time to avoid overwork.

4. Regulate the mood, be lenient to others, be less angry, optimistic, and positive.

5. Try to avoid chest and head injuries.

Is it that the squatting time is long and the hair is dizzy.
