Why do you feel dizzy when you get up suddenly

When a person is in a squatting position, the lower limbs are flexed, and the blood vessels of the lower limbs are compressed so that the blood is not easy to flow to the lower limbs, and the lower limbs appear to be ischemia. When a person who has been squatting for a long time suddenly stands up, the blood vessels of the lower limbs are restored to unblocked, and at this time, it is like suddenly opening the floodgates, and the blood will rush to the lower limbs in large quantities, so that the head will not have enough blood, and the brain will not get enough oxygen and nutrition for a while. The conclusion is:

Most of this phenomenon is a normal phenomenon and is not caused by anemia. Reminder: 1. It is best not to squat for a long time for people with this phenomenon, if you have to squat often due to work, you can prepare a low stool in advance to reduce the degree of flexion of the lower limbs; 2. When standing up after squatting for a long time, it is advisable to stand up slowly to reduce the discomfort caused by this; Care should even be taken to clean up the work site to prevent injuries after a brief loss of consciousness and a fall to the ground.

3. It is advisable to participate in more physical exercise to enhance cardiovascular function. Why do people get dizzy when they stand up after squatting for a long time? If you squat on the ground for a little longer, and when you stand up suddenly, you often feel the world spinning and your eyes are full of stars.

This is caused by temporary anemia of the head. When a person is squatting, there are some special cases for the distribution of blood in the body. The first is that the two legs are pressed very tightly, the blood vessels are flattened, and the blood reaching the lower limbs is relatively small; Secondly, because the head is slightly tilted forward when squatting, the blood to the head is relatively more distributed.

When you stand up suddenly, the blood vessels in the lower limbs suddenly release the compression, so a significant part of the blood flows to the lower half of the body. In addition, blood also has a certain weight in the body, and when you stand up suddenly, the blood flow will also flow to the lower half of the body due to the attraction of gravity and inertia, and the blood distributed to the upper body will be reduced. In addition, when standing up, the head is also upright, and it is more difficult to spurt blood from the heart to the high head.

All of this results in a relative decrease in blood flow to the head. The human brain is the most in need of blood oxygen, and a temporary reduction in blood supply can make people feel dizzy due to temporary cerebral anemia. In addition, due to the decrease in blood in the head, the blood supply to the eyeballs is naturally less, so the phenomenon of dazzling and Venus will occur.

At the same time, anemia and hypoglycemia can aggravate this phenomenon. 37 hopes.

Low blood pressure, dizziness, cerebral insufficiency, health, anemia.

Finally, many elderly people also often experience vertigo, which may be due to a cerebral infarction. When such a disease occurs, it is easy for the elderly to be unsteady on their feet and fall down. I couldn't get up again after this fall, and that's how my grandmother died.

I hope you can pay attention to the physical condition of the elderly at home and give ** in time.

I believe that many friends will occasionally have symptoms of vertigo, especially after squatting and then standing up, it will be easy to have black eyes and unsteady standing, these are symptoms of vertigo, if this happens, it is best to go to the hospital to diagnose and prescribe the right medicine.

It may be that there is low blood pressure, you should go to bed early and get up early in your life, don't stay up late, you should also eat some red dates, or it may be that you have low blood sugar, you can go to the hospital for examination.

If there is a sudden state of vertigo, it may be because there is some problem with the nerve part of the brain, if the state of vertigo is often occurring, it is recommended to go to the hospital as soon as possible for a detailed examination to ensure your own safety.

It could be that you have low blood sugar. Therefore, you must always have sugar on hand. To prevent yourself from fainting when no one comes to save you.

Dizziness can also be divided into several conditions.

There are several possible causes in terms of symptoms.

Vertigo can be categorized into two categories, one is "ordinary dizziness" and the other is "recurrent vertigo" caused by problems with the balance system. Dr. Tong pointed out that many examples of dizziness are "ordinary dizziness", which may be caused by a cold, a physical infection, or high or low blood pressure, but when these symptoms disappear, the dizziness will also subside. As for the condition commonly described as "ear fluid imbalance", it is usually caused by a malfunction in the balance system, resulting in a whirlwind and seasickness.

Some of the causes are cervical spondylosis, and some dizziness is caused by the brain's ability to balance underground, such as Meniere's disease'S disease) is a condition in which dizziness is caused by an enlarged lymphocele or fluid accumulation in the inner ear, and the patient suddenly feels the world spinning, usually for only a few tens of seconds

What causes me to get dizzy when I get up suddenly? Let's take a look at this problem**, I hope these contents can help friends in need.

After squatting for a relatively long time, I suddenly feel dizzy when I stand up, I feel that there are many stars in front of me, and everything is blurred, which is due to the transformation of high blood pressure in the body, especially the nutrients of the brain and brain ** There is a problem with O2**.

Everyone's brain must have enough nutrients to be able to run normally, although the brain is the core of guiding everyone's body, and the nutrients of everyone's body must be based on the brain, but everyone squats on the ground, for a long time, there is a problem with the circulatory system of the blood night, so there is a problem with the medium of transporting nutrients, and the brain will also have a lack of nutrients, just like a general headquarters, which materials are the first to choose** it, but there is a problem with the transport car, and it is useless to be anxious. There is no doubt that there will be a shortage of supplies at the General Command.

Under the condition that everything is normal in everyone's body, the high and low voltage is all stable, it is very likely that ordinary people are low voltage 80 100, high pressure 120 140, more than 140 is already a little high blood pressure, everyone squatting on the ground The circulatory system of the blood night is concentrated in its own lower body, and suddenly stands up and suffers from the harm of the force, and a part of the blood night stays in the lower body, and its repetition rate is harmed, and everyone's brain will feel dizzy, but generally speaking, there is no big problemSometimes it happens, that is, you have been squatting for too long, but if it happens often, the reflection is very obvious, it means that you are likely to have a little high or low blood pressure.

Regarding the problem of blood pressure value regulation, in fact, no one has any way, due to high blood pressure, high blood lipids, high blood sugar, and the symptoms of three highs confuse many groups, he is not easy to take people's lives, but he is very obvious to endanger everyone's daily life, so we can do while we are young is also to moderately regulate their own work and rest time, scientific and reasonable overall planning of dietary structure, moderate exercise, improve their body resistance, the probability of chronic diseases in the future will decline a lot.

Sudden uplift may be due to holding a posture for a long time, resulting in poor blood flow, and then suddenly getting up in the process of causing blood pressure to drop, resulting in insufficient blood supply to the brain.

This is because our nervous system cannot respond temporarily, and our brain does not have enough blood supply to command our body well, and there will be a temporary command gap.

When you get up, you will suddenly feel dizzy, probably because the blood in the body cannot be replenished to the brain in time; It may also be because the blood sugar concentration in the body is too low.

According to expert Professor Diao Wenjing, there are many causes of vertigo. Some are due to low blood pressure, insufficient blood supply to the brain, and even fainting. For example, at the 1996 Atlanta Olympic Games, China's famous shooter Wang Yifu fainted on the field, which was caused by this reason.

Many patients with cervical spondylosis have symptoms of vertigo, which are mainly manifested as dizziness, tinnitus, nausea, and even deafness, dizziness, and inability to see clearly. The main characteristics are nausea and even vomiting, paleness, sometimes sweating, unable to even walk, and need help. 80 vertigo is related to cervical intervertebral joint misalignment, how does vertigo occur?

I believe that about 80% of vertigo is related to cervical intervertebral joint misalignment, except for congenital factors such as cranial nerve malformations or organic lesions caused by trauma. We know that the vertebral artery is an important "conduit" in the human body, which leads through the cervical spine to the brain and is responsible for blood delivery to the brain. Any misalignment, hyperplasia and other problems in the cervical spine may damage or affect this blood supply "pipe", which in turn affects the blood supply to the brain.

Vertigo is caused by the dislocation of the occipital atlas vertebra and the atlantoaxial intervertebral joint compressing the third segment of the vertebral artery, resulting in insufficient blood supply and oxygen supply to the cerebral basilar artery, at this time, the brainstem, cerebellum, diencephalon and brain are hypoxic and ischemia, and the labyrinth artery and the internal auditory artery are also ischemia and hypoxia, resulting in ear nerve disorders and tinnitus and deafness; At the same time, due to the compression of the upper cervical sympathetic nerve, the cerebral vascular spasm is aggravated, and the cerebral ischemia state is aggravated, so symptoms such as dizziness appear.

On July 18, 2009, the "Diao's Spine of Traditional Chinese Medicine" was jointly organized by the Beijing Municipal Administration of Traditional Chinese Medicine, the Beijing Municipal Health Bureau, the China Medical and Health Development Association, and the China Folk Chinese Medicine Research and Development Association""The launching ceremony and development seminar of the "Cardiac Neurosis" municipal scientific research project was held in Beijing. The results of Professor Diao's research on vertigo are: for vertigo diagnosed as being caused by dislocation of the occipital atlantoaxial joint or atlantoaxial joint, the ** rate is 83 and the effective rate is 96.

How can it be treated? That is to use the "Chinese medicine Diao's spine joint five-point one-line manual reduction" to perform manual reduction for the dislocated intervertebral joints. With the correction of the misaligned intervertebral joints, the corresponding tissues and organs reach relative balance, and symptoms such as dizziness will naturally be relieved and eliminated.

It may be caused by temporary cerebral hypoxia, or it may be caused by other physical diseases, such as vertigo, Meniere's syndrome, etc.
