How can I faint when I m standing, why do I faint all of a sudden?

Several reasons: 1. Hypoglycemia 2, cervical spondylosis 3, high vertigo (a relatively new medical term) The mechanism is not clear, mild is not considered a disease, severe will be shocked, lying flat will be alleviated, and now seasickness. Most of the main reasons are caused by mild occupational diseases such as sedentary office personnel and salesmen, pay attention to exercise, reduce the pressure of life will be relieved, when standing for a long time, you lean the center of gravity of the body slightly forward, and the soles of your toes and feet work together to support the body, which will be relieved.

It may be hypoglycemia or anemia. Of course, low blood pressure can also cause this.

If you just faint and immediately come to your senses, it may be general anemia or hypoglycemia.

It is recommended to exercise more, eat some red dates, glucose.

If possible, you can also go to the hospital for some daily physical examinations.

I guess it's your low blood sugar! Drink some glucose and you'll be fine! And remember to have breakfast in the morning!

It's probably anemia, and it's not enough nutrients!

Weakness is likely to be anemia, and there is no more nutrition!

Is it not a good rest, pay attention to reasonable time arrangement.

If you just wake up in the morning, it must be low blood sugar

Didn't eat early, low blood sugar.

It's not **, right?

Either that, or neurosyncope.

You didn't do a good job at night, haha.

When the flag was raised this morning, I saw a student fainting to the ground! Therefore, there is a question that asks this question: "".

After helping the students into the infirmary, they will return to normal state after sitting for a while, and ask carefully to understand the specific situation: after standing for a long time, they will feel chest tightness and shortness of breath, dizziness and then dizziness, and then they will faint, but if they can squat or sit before fainting, they will feel better, and it will also reduce the occurrence of fainting. After fainting for a while, you will wake up on your own.

Under normal circumstances, you don't faint when you're tired when you walk, but you can do this when you stand for a while, but not every day, but a few times a year. Analysis: 1, check blood pressure:

It can be caused by low blood pressure, anemia, or insufficient blood supply to the brain. 2. There may also be cerebral embolism, etc. There are a lot of issues to consider.

Most of these problems are caused by the liver. Cerebrum. When a heart test is done, it is most likely caused by insufficient blood supply.

If you are older, it is estimated that it is coronary heart disease, and coronary heart disease usually has no problem with blood pressure, but if it is abnormal, it will kill you, you can do blood sugar and lipid tests first. 3. It is a weak body, poor blood circulation, and low oxygen carrying capacity of hemoglobin, resulting in poor blood supply to the brain. Usually pay more attention to recuperation, it should be congenital, and nourishment is the key!

4. It is recommended that this kind of person will press the blood vessels of the feet after standing for a long time, and the body should lean forward to get better! With the check, it is easy to analyze and eliminate some problems.

This is generally normal, because when squatting down, the blood is concentrated throughout the body, and when you stand up suddenly, the blood in the head does not have time to **, and temporary cerebral ischemia occurs, resulting in a feeling of dizziness. If you feel dizzy while sitting and standing, you may have anemia or low blood pressure, and you should be checked.

It is possible that you often skip breakfast, causing low blood sugar.

Here are a few things you need to pay attention to:

Blood sugar. Low blood sugar due to frequent or occasional skipping of breakfast. People experience vertigo.

The second is that you should exercise very little, and exercise more, because you are chasing the bus, which is a sudden strenuous exercise that causes the body to collapse. Symptoms similar to heat stroke occur, such conditions are very harmful to the body, and even life-threatening, so you need to be cautious!

Then it is recommended to check the kidneys, there may be kidney deficiency.

Didn't eat breakfast Blood sugar is low, and if you eat breakfast, you'll be fine.

Insufficient blood supply to the brain, causing hypoxia, is also a symptom of hypoglycemia, dizziness is normal, but fainting is not normal, usually pay attention to diet, breakfast is particularly important, eat more high-protein food, replenish energy at any time.

Why does a healthy person faint?

It is due to various reasons that the brain is in a temporary ischemia and the sudden and temporary loss of consciousness and consciousness and behavioral ability occurs, which is called "syncope" in medicine.

Normal people have syncope under certain circumstances, which is a physiological phenomenon. As long as we remove the cause, this physiological phenomenon can be prevented.

However, it should be noted that if a person often faints, accompanied by headaches, convulsions, inconvenient movement of hands and feet, irregular heartbeat, anemia and other symptoms, it is not physiological, but pathological syncope, and it is necessary to go to the hospital for examination, **!

2.Blood sickness reaction, also known as blood sickness. It is a mental disorder in a special situation, except that the person who cannot see blood, the person who faints blood is no different from ordinary people. People who suffer from fainting disorder feel frightened, dizzy, and nauseous when they see blood; In severe cases, they will lose consciousness and consciousness.

3.The presence of both of these causes accelerates the onset of shock (fainting).

Treatment: The patient should be placed in a warm room first, given oxygen, lying on the patient's back, fed warm water or sugar water, resting for 10-15 minutes, and generally recovering, and if necessary, drug rescue should be given**.

It generally refers to sudden fainting, also known as fainting or syncope. Fainting is a sudden and transient loss of consciousness that lasts from a few seconds to a few minutes, and the onset is caused by a temporary lack of blood or oxygen supply to the brain, and the recovery is relatively fast. Coma, on the other hand, is a prolonged loss of consciousness that makes recovery slow and difficult.

The causes of fainting are: 1 Reflex syncope: 1 Vasosuppressive syncope - the most common, accounting for more than 50%.

Syncope is often induced by fatigue, fasting, poor ventilation, and mental factors (nervousness, fear, pain); Prodromal symptoms such as transient dizziness, dizziness, weakness, and limb weakness before syncope; Syncope is accompanied by slowed heartbeat, decreased blood pressure (reflexive increase in the later stage), paleness, etc., and the recovery is rapid without obvious sequelae. 2 Orthostatic hypotension - often occurs when the supine position is converted to an upright position, and can also occur when standing for a long time, and the blood pressure drops during syncope without obvious changes in heart rate.

3 Micturition syncope - mostly in young and middle-aged men, syncope often occurs during or after urination. 4 Carotid sinus syncope – seen in middle age and above, syncope is associated with a sudden turn of the head. 2. Cardiac syncope:

Patients often have a history of heart disease, which is often caused by severe arrhythmias, such as high tachycardia, bradycardia (less than 40 points) or asystole, valvular heart disease, obstructive cardiomyopathy, atrial myxoma, etc., resulting in cerebral insufficiency and syncope. 3. Cerebral syncope: Common cerebrovascular diseases such as cerebral arteriosclerosis, cerebral vascular stenosis or obstruction, transient cerebral ischemia, pulseism, epilepsy, craniocerebral injury, etc.

4. Metabolic and hematologic syncope: Hypoglycemic syncope is common, the seizures are related to fasting, and can also occur 2 to 4 hours after a meal, syncope often occurs slowly, and recovery is also slow. There is no significant change in blood pressure and pulse at the time of attack, and blood glucose levels often do not match symptoms.

Severe anemia can also cause fainting. 5. Psychogenic syncope: seen in hysteria, hyperventilation, etc.
