Why does the human body lack oxygen, and what problems will occur after the human body is hypoxic?

Under what circumstances the human body is deprived of oxygen.

What problems will occur when the human body is deprived of oxygen? Let's take a look!

Insufficient oxygen can cause changes in the body that cannot be metabolized properly. In an oxygen-deficient environment, the central nervous system of the human body.

Cardiovascular, respiratory, liver, kidneys, tissue cells, etc. are all affected, and long-term living in a hypoxic environment will cause irreparable damage to brain tissue, for example, mountaineers will have fatigue, indifferent expression, drowsiness, incoherent speech and other mental symptoms due to lack of oxygen, which is the possibility of hypoxia.

When the human body is deprived of oxygen, it affects the central nervous system. Dizziness and headache occur.

Symptoms such as weakness, unresponsiveness, fatigue, and drowsiness. Affect the respiratory system, and symptoms such as chest discomfort, difficulty breathing, itchy throat, and cough appear. Affects the circulatory system, palpitations appear.

Symptoms such as a rapid or slowed heartbeat. Affects the digestive system.

Symptoms such as appetite, complacency, and constipation occur. At the same time, mouth sores.

Pharyngitis, bleeding gums, dandruff, pallor, wounds that do not heal easily, etc. can also be alarms from the body when there is a lack of oxygen. Long-term hypoxia leads to decreased immunity and susceptibility to colds.

After the body is deprived of oxygen, it will lead to dizziness in the body, and the heart can supply blood to all organs of the body, especially the amount of blood transported by the brain accounts for 15% of the total, and the oxygen consumption of the brain accounts for 23% of the human body, far exceeding the average level. If oxygen is not supplied to the brain parts in a timely manner, the functioning of the brain will be affected, and mild people will become dizzy, and over time, memory will also decline. I haven't done much physical work in the recent period and have plenty of rest time, but I still have physical fatigue and weakness in my limbs during the day, which means that my body is deprived of oxygen.

When you are in a state of hypoxia, the various organs in the body cannot function normally, which can cause fatigue. When it comes to the symptoms of edema, some people simply think of decreased kidney function or drinking too much water, but it is not well understood that edema can also be a sign of hypoxia. This is because the cells are hypoxic after electrolytes.

If the sodium ion increases, the excess water will enter the cell, so it will first cause cell edema, and then compress the surrounding microvessels, resulting in poor microvascular circulation.

Due to the lack of oxygen supply to multiple organs in the body, some diseases of the lungs occur at this time, due to long-term hypoxia, it will cause degeneration of the lungs, and the lung tissue will be damaged to varying degrees, such as the expansion of the lungs, and the fibrosis and calcification of the lung tissue to different degrees, resulting in bronchial asthma.

It will cause various organs to be very uncomfortable, there will be chest tightness, dizziness, weakness of limbs, and tinnitus.

There will be shortness of breath, which is likely to cause suffocation, and you will also feel sick to your stomach, foaming at the mouth, and nausea.

Professionals believe that there is lipid deposition in the lumen of blood vessels, and the blood is not smooth. Cardiovascular and cerebrovascular patients with difficulty in oxygen supply, blood viscosity, coronary arteriosclerosis, narrowing of the lumen of blood vessels, resulting in poor blood supply and difficulty in oxygen supply.

The body is "starved of oxygen" every day. Long-term mild hypoxia of the heart. The function of organs that consume the most oxygen, such as the brain, gradually declines.

Severe hypoxia will cause "myocardial infarction" and "cerebral infarction", and if oxygen is not provided in time, it will lead to sudden death. Therefore, cardiovascular and cerebrovascular patients can effectively prevent the occurrence of danger by using pulse oximetry to detect blood oxygen content for a long time.

People with respiratory diseases (asthma. Tracheitis. Old and slow. Cor pulmonale, chronic obstructive pulmonary disease...

On the one hand, dyspnea will lead to insufficient oxygen uptake, on the other hand, the continuation of asthma will also block the small branch organs, making gas exchange difficult, resulting in hypoxia, resulting in cardiopulmonary disease. Varying degrees of damage to the brain and even kidneys. Therefore, the pulse oximeter is used to detect the blood oxygen content, which greatly reduces the incidence of respiratory tract.

Seniors over 60 years of age.

The cardiopulmonary organs are physiologically aging and oxygen uptake is insufficient. Inadequate oxygen supply.

The human body relies on blood to transport oxygen, and when there is less blood, there will naturally be less oxygen. If there is less oxygen, the physical condition will naturally decline, so the elderly should use pulse oximetry to measure the blood oxygen content every day, and once the blood oxygen is lower than the warning level, oxygen needs to be replenished as soon as possible.

First of all, you need to know what will reduce the blood oxygen content of the human body, for example, many respiratory diseases will cause the reduction of oxygen saturation in the human blood, and the automatic adjustment of the body caused by anesthesia, major surgical trauma, and some injuries caused by medical examinations, etc., may lead to problems with the patient's oxygen supply and reduce the body's blood oxygen saturation; As a result, patients may experience symptoms such as dizziness, weakness, vomiting, and in severe cases, it can be life-threatening.

Various cardiovascular and cerebrovascular diseases, especially those with heart failure (such as coronary heart disease, wind heart disease, congenital heart disease, etc.).

Patients with chronic obstructive pulmonary disease (COPD) and respiratory distress syndrome (ARDS) and other lung diseases: chronic bronchia, cor pulmonale, asthma, etc.

People who live in the plateau or who have been suffering from mountain sickness since entering the plateau area.

and so on are the main causes of hypoxia. After excluding the above, it is very helpful to exercise more and do more aerobic training to improve the blood oxygen content of the human body, I hope mine can help you.

1. It increases the number of red blood cells in the body, the blood viscosity is high, the peripheral vascular resistance is increased, the burden on the heart is increased, heart failure is caused or aggravated, and it is easy to induce cerebral thrombosis; Long-term hypoxia of the brain can produce a series of psychiatric and neurological symptoms: such as sleep disorders, mental decline, memory loss, abnormal behavior, personality changes, etc.

2. Long-term severe hypoxia can cause pulmonary vasoconstriction, resulting in pulmonary hypertension, increased burden on the right ventricle, and pulmonary heart disease in the long run; Hypoxia can aggravate hypertension, increase the burden on the left heart, and even cause arrhythmias;

Hello, the lack of oxygen can have adverse effects on the human body, the main one of which is the nervous system. When the body is deprived of oxygen, brain cells are damaged, and symptoms such as headaches, insomnia, memory loss, dizziness, and mental fatigue occur. In addition, hypoxia can also affect heart muscle cells, leading to myocardial ischemia, which can lead to heart diseases such as angina pectoris, arrhythmias, etc.

In addition, hypoxia can also affect the lungs, causing damage to lung cells, which can lead to diseases such as emphysema and pneumonia. In addition, hypoxia can also affect blood circulation, resulting in poor blood circulation, which can cause symptoms such as dizziness, nausea, and difficulty breathing. Therefore, hypoxia can have adverse effects on the human body, and hypoxia should be avoided as much as possible.
