Will there be sequelae of altitude sickness? What is altitude sickness?

Generally, there will be no sequelae, that is, the physiological performance of the person's adaptation to the new environment, and the person's physique, do not be overly nervous. Forget.

Strictly speaking, yes. Mild cases can disappear on their own without sequelae, more serious goods have some sequelae, because the lack of oxygen in the heart and brain can easily cause adverse reactions in the body, some are long-term, some will get better with the change of the environment, different from person to person, if you will still have serious discomfort after going to the doctor, so as not to cause greater problems.

Altitude sickness is a variety of pathological reactions produced by the human body after rapid exposure to low-pressure and low-oxygen environment, and is a common disease unique to plateau areas. Common symptoms include headache, insomnia, loss of appetite, tiredness, difficulty breathing, etc. Headache is the most common symptom and is often a throbbing pain in the forehead and both temporal regions, which worsens at night or in the morning when you wake up.

Increased ventilation of the lungs, such as breathing through the mouth and light activity, may reduce headaches.

The incidence of altitude sickness is related to the speed of climbing, altitude, length of residence, and physical fitness. Generally speaking, when plain people quickly enter the plateau above 3000m above sea level, 50% and 75% of people have altitude sickness, but the symptoms gradually disappear after 3 to 10 days of habit. The incidence of this disease is lower in the elderly than in young people, and in women than in men; The incidence of altitude sickness was positively correlated with the body mass index of men and not with the body mass index of women, indicating that obese men were more susceptible.

Altitude sickness is caused by hypoxia, low pressure, and dryness in the plateau environment. You can eat rhodiola in advance to lay a foundation for your body, and when you go to the plateau, you can carry anti-hyperreflective products such as glucose solution and Omo brand blue tablets, which have a good relieving effect. If you are used to the taste of butter tea, you can drink some butter tea, which will help you adapt to the plateau environment.

Altitude sickness can be manifested as cardiovascular, cerebrovascular, and gastrointestinal symptoms when the degree of harm to the human body is mild, and can cause pulmonary edema and cerebral edema in severe cases.

1.Mild altitude sickness often causes headaches, insomnia, palpitations, nausea, etc., and symptoms can be improved by taking medications and reducing the amount of activity.

2.The most common cases of severe altitude sickness are high-altitude pulmonary edema and high-altitude cerebral edema, which may be caused by high-altitude pulmonary edema when symptoms of dry cough, dyspnea, or cyanosis appear; If you feel confused and have a severe headache, you may develop high-altitude cerebral edema. When the above severe altitude sickness appears, it is necessary to seek medical attention immediately** and leave the place where altitude sickness is caused immediately to avoid life-threatening.

The occurrence of altitude sickness is mainly due to the lack of oxygen in the human body, which leads to pathological changes in various organs, causing a series of corresponding clinical manifestations. **Altitude sickness, which needs to be treated according to the condition**. When the condition is relatively mild, symptomatic oxygen inhalation as soon as possible can be relieved; In severe cases, high-flow oxygen is required, and when pulmonary edema and cerebral edema occur, immediate rescue measures need to be taken and ventilator-assisted ventilation is required.

To prevent the occurrence of altitude sickness, the following can be taken:

1. Do a physical examination before entering the high-altitude area.

2. Maintain a good mood, get enough sleep, and eat a balanced diet.

3. Prepare in advance the common drugs for altitude sickness.

Fourth, the gradual transition from low altitude to high altitude areas.

Fifth, oxygen can be appropriately inhaled to alleviate altitude sickness.

Lhasa is 3,650 meters above sea level, and it is easy to suffer from altitude sickness. However, altitude sickness varies from person to person, and altitude sickness focuses on resistance, and not everyone will have it. However, taking an airplane is more likely to occur than self-driving and taking a train, after all, taking a train is not a one-time arrival, and the gradual increase in altitude on the train can allow the human body to have a relatively slow adaptation process.

However, this does not mean that the train entering Lhasa will not cause a high reaction, because it mainly depends on the individual's physique. Another point is not to take a bath and wash your hair, do not drink, do not exercise vigorously within two or three days after arriving in Lhasa, this is what the tour guide who took me to me before focused on and said, because the air in the plateau area is thin, the oxygen content is low, and the lack of oxygen supply will lead to headache, dizziness, and even vomiting, and in severe cases, pulmonary edema will occur, and bathing, drinking, and exercise will accelerate blood circulation, which will lead to accelerated breathing, and the plateau is hypoxic, so it will be easy to have altitude sickness. Many people are in the plateau area, including me, altitude sickness does not appear immediately, many of them have high reaction that night, and some are the second or third day, so generally pay attention to the first three days and do not do behaviors that will cause high reaction.

Therefore, it is recommended to prepare sufficient materials when you are ready to go, such as appropriate thick clothes, because the temperature difference between day and night is relatively large; There are also some anti-anti-anti-anti-anti-anti-anti

Altitude sickness is a natural physiological reaction produced by the human body after reaching a certain altitude, in order to adapt to the changes in air pressure difference, low oxygen content, and dry air caused by altitude, and the altitude generally reaches about 2700 meters.

First, we need to understand the relationship between atmospheric pressure and air density.

1. What is atmospheric pressure?

Atmospheric pressure refers to the pressure exerted by the atmosphere on the earth's surface. You can imagine that the atmosphere is like a huge weight of air that exerts pressure on the Earth's surface. The magnitude of this pressure can be expressed in terms of atmospheric pressure.

The magnitude of atmospheric pressure is related to factors such as altitude, air temperature, and humidity. In general, as the altitude increases, the atmospheric pressure gradually decreases. This is because as the altitude increases, the atmosphere becomes thinner and the pressure on the Earth's surface decreases.

Relationship between air density and atmospheric pressureAir density refers to the amount of air in a unit volume. Under standard conditions (0°C and atmospheric pressure 101325 Pa), the density of air is approx.

As the atmospheric pressure decreases, so does the density of the air. This is because the volume of air is fixed, and if the atmospheric pressure decreases, then the air molecules have to be arranged more sparsely to maintain the same volume. As a result, the number of air molecules per unit volume decreases, resulting in a decrease in air density.

2. Why is the oxygen content in the plateau area decreasing?

In the plateau area, the air density is also lower due to the lower atmospheric pressure, so the number of oxygen molecules per unit volume decreases accordingly. This means that the oxygen content in the air in the highlands is relatively low. In addition, the climate and environment of the plateau area also affect the oxygen content.

For example, temperatures in highland areas are usually cooler, which leads to an increase in condensation in the respiratory tract during breathing, which affects the ability of oxygen to enter the lungs.

3. How to prevent high reaction?

Take anti-hyperreflex health foods in advance, plateau safety, rhodiola, etc., eat more vegetables, fruits and other vitamin-rich substances, pay attention to keeping warm, rest more on the plateau, relax your mind, and don't be afraid of hyperreflex.

First, the cause of high reaction.

Altitude sickness generally refers to a series of uncomfortable reactions that occur in the body at an altitude of more than 3,000 meters, generally speaking, there are different symptoms such as headache, loss of appetite, hypoxia, tinnitus, etc.

Normal people basically experience purple lips, slight dizziness, and poor sleep in the first two nights.

2. Common symptoms.

The more common manifestations are: chest tightness, sleepiness, shortness of breath, headache, nausea, dizziness, dry cough, fatigue, anorexia, vomiting, drowsiness, slight fever, etc.

Most people: Lips and nails will turn purple due to lack of oxygen, and some people will also have **roughness, chapped lips, bleeding nostrils, etc. due to dry air.

In severe cases, there will be dull sensation, emotional restlessness, hyperactivity, thinking and memory loss, abnormal hearing, sight, smell, taste, hallucinations, etc., and edema, shock or spasms may also occur.

Extremely severe: High-altitude pulmonary edema or cerebral edema is a very serious form of mountain sickness, and the symptoms associated with them are generally fatal (relatively rare, but not negligible).

3. Prepare high-anti drugs.

999 cold medicine.

Traveling on the plateau, the temperature difference between day and night is large, and it will be very troublesome if you catch a cold, so drink a bag every night to prevent colds.

Highland Ann. Start taking it on the day of departure from the plateau, which can effectively relieve the physical discomfort caused by high reaction.

Ibuprofen. Painkillers, take them when you have a high reaction headache, but don't take them at night to avoid ignoring the symptoms of high reaction.

Huoxiang Zhengqi oral liquid.

It is useful for high reaction, motion sickness, and gastrointestinal discomfort, but be careful not to drink this while driving, it contains alcohol.

Erythromycin ointment.

The plateau climate is dry, so you can use a cotton swab to dip a little in your nostrils at night before going to bed to prevent nosebleeds.

What are the causes of altitude sickness and how can it be prevented?

1. What is high anti-reaction?

To put it simply: it is the human body that is not adapted to the environment in the case of lack of oxygen, and the altitude generally reaches 2500 3000 meters, and there will be altitude sickness.

Second, the crowd that is prone to high reaction:

Female" male, short "tall", skinny "fat", young "older".

People with fast metabolism are also prone to hyperreflex.

People who exercise regularly are also more likely to occur because their oxygen consumption is higher than others.

3. So how to prevent it

Plateau and Rhodiola can be properly prepared; Rhodiola generally needs to be eaten in advance, and you can prepare it in advance.

Stop exercising a week before entering the plateau.

Do a comprehensive physical examination to be prepared, and enter the plateau in strict accordance with the doctor's instructions.

Fourth, countermeasures should be taken against high countermeasures

When you first arrive at the plateau, you should stay in retreat, and it is recommended that you start your journey slowly after getting used to it.

Drink plenty of water and eat plenty of carbohydrates to digest well.

Plateau areas are prone to loss of appetite, it is recommended to prepare some glucose, if you can't eat, you can drink glucose to replenish your strength.

It is easy to suffer from insomnia in highland areas, so it is recommended to prepare melatonin tablets to improve sleep.

It is advisable to go in a group, as it is easy for us to overestimate our physical state in case we can take care of each other.

Oxygen inhalation can immediately alleviate high reaction, but once you stop inhaling oxygen, altitude sickness will occur, it is recommended to let the body slowly adapt to the altitude environment, and oxygen inhalation will prolong the time for the body to adapt to the altitude.
