Can you travel to Tibet with one kidney constitution?

1. People who are not suitable for traveling to Tibet

Patients with obvious pathological changes in heart, lung, brain, liver and kidney, and patients with severe anemia or hypertension should not enter the plateau with their eyes closed. If you have never been to the plateau, it is recommended that you have a strict physical examination before entering the plateau.

tourists with organic diseases, severe anemia or severe hypertension have poor adaptability to the plateau environment. In the early stage of entering the plateau, the risk of acute altitude sickness is obviously higher than others; If you stay in the plateau for too long, you are more likely to suffer from various chronic altitude sickness than others. At the same time, due to the adaptation of the body to the plateau environment, the compensatory activities of important organs such as liver, lung, heart and kidney are enhanced, which aggravates the burden of these organs. Once these organs have diseases, it will further aggravate the condition.

If you are not sure whether you can participate in the travel activities in Tibet, I suggest you consult an experienced doctor and try to be prudent.

2. Preparation before entering the plateau

(1). Before entering the plateau, you can consult people who have lived in the plateau for matters needing attention, so as to be aware of it and avoid unnecessary tension.

(2) Before entering the plateau, alcohol and tobacco are prohibited to prevent upper respiratory tract infection. Avoid being overworked, save your strength and have a good rest. Take American ginseng properly to enhance the anti-hypoxia ability of the body. If there is a respiratory infection, it should be cured before entering the plateau.

(3) Good psychological quality is a panacea for overcoming altitude sickness. A large number of examples have proved that maintaining an open-minded and optimistic mood and establishing strong self-confidence can weaken the physical discomfort in the altitude sickness zone. On the contrary, anxiety, overthinking, and slight discomfort will lead to high altitude tension, but it will increase the oxygen consumption of brain tissue, thus aggravating physical discomfort and prolonging the self-healing time.

(4). If you have never been to the plateau, you must have a strict physical examination before entering the plateau. Patients with severe anemia or hypertension should not enter the plateau with their eyes closed.

3. Precautions on the way into the plateau

(1). Oxygen and drugs for preventing and treating acute altitude sickness, such as nifedipine (also known as nifedipine) and aminophylline, should be prepared as much as possible, as well as drugs for preventing and treating colds, antibiotics and vitamins, just in case.

(2) Due to the cold climate in the plateau and the large temperature difference between day and night, it is necessary to prepare enough warm clothes to prevent catching cold. Both cold and respiratory tract infection may cause acute altitude sickness.

(3) If severe symptoms of altitude sickness appear on the way to the plateau, they should be treated immediately, and aminophylline or nifedipine 2mg should be taken under the tongue in time. In severe cases, oxygen should be inhaled. In case of severe chest tightness, severe cough, dyspnea, pink foam sputum cough, or slow response, apathy, or even coma, in addition to the above treatment, you should go to a nearby hospital for rescue as soon as possible, or transfer to a lower altitude area as soon as possible for treatment and recovery.

(4). Because it takes time and labor to enter the plateau by car, the accommodation conditions on the way are poor and the physical strength is high, in addition to the above items, water or drinks and delicious and digestible food should be prepared to replenish the necessary water and heat for the body in time.

3. Altitude sickness → When traveling in Tibet, the most important thing to pay attention to is altitude sickness.

it varies from person to person, and it is difficult to predict before going to high school. The physically weak may not react greatly, and the physically strong may not respond. Everyone's reaction is also different. Generally speaking, thin people are better than fat people, women are better than men, short people are better than tall people, and young people are better than old people.

After entering the plateau from the plain, the regulatory changes of human body are mainly manifested in the following aspects:

(1). Pulse (heart rate) frequency: The normal pulse in the plain is 72 beats/min, which can be increased to 8-9 beats/min when you first arrive at the plateau, and can reach more than 1 times/min for an individual, and can be recovered after living for a period of time.

(2). Breathing: When the respiratory system is slightly hypoxic, it first shows that breathing deepens and accelerates, and the breathing frequency is further accelerated with the aggravation of hypoxia, and people feel chest tightness and shortness of breath. After adaptation, it will gradually return to its original level.

(3). blood pressure: the normal systolic blood pressure is 11 ~ 12mm Hg, and the diastolic blood pressure is ~ 8mm Hg. After entering the plateau for the first time, due to the influence of vascular receptors and body fluids, blood vessels such as skin and abdominal organs contract and blood pressure rises, thus ensuring the blood supply in coronary arteries and cerebral vessels. It will return to normal after adaptation.

(4) nervous system: the central nervous system, especially the brain, is extremely sensitive to hypoxia. When there is mild hypoxia, the excitability of the whole nervous system is enhanced, such as emotional tension and excitability, and then headache, dizziness, insomnia and forgetfulness occur. After entering a higher altitude area, it changes from excitement to inhibition, showing drowsiness, apathy and unresponsiveness. A few serious people will lose consciousness or even coma, and will return to normal if they are transferred to the lowlands. The severity of neurological symptoms is often closely related to my psychological state and mental mood. People who are afraid of the plateau and lack mental preparation will react more; On the contrary, people who are happy have less reaction.

(5) Digestive system: The secretion of digestive glands and gastrointestinal peristalsis entering the plateau were inhibited, except the secretion of pancreas increased slightly, the secretion of saliva, intestinal juice, bile and other digestive foods decreased compared with that in the plain, and the gastrointestinal function was obviously weakened. Therefore, there may be a series of digestive system disorders such as loss of appetite, bloating, diarrhea or constipation, and upper abdominal pain. After living in the plateau for a period of time, you can gradually recover.

At high altitude, if you continue to feel unwell, you should go to the hospital for treatment. The most important thing is not to carry the burden of psychological fear on the plateau.

4. Matters needing attention after arriving at the plateau

(1). When arriving at the plateau, everyone will feel different degrees of hypoxia symptoms such as shortness of breath, chest tightness and difficulty breathing. But this doesn't mean that you can't adapt to the plateau. If you can protect yourself correctly, the above symptoms can generally be improved or disappeared after 2 to 4 days.

(2). If you go to the plateau by plane, the symptoms of altitude sickness will generally occur in about 12 to 14 hours. Therefore, when you first arrive at the plateau, you must not be violently transported, but stay in bed immediately. Otherwise, once you feel the reaction, you need more time to adapt.

(3) People often use salivary oxygen inhalation to relieve the discomfort of chest distress. Of course, oxygen inhalation can temporarily relieve chest tightness, shortness of breath, dyspnea and other symptoms, but after stopping oxygen inhalation, the symptoms will reappear, delaying the time to adapt to the plateau. If the above symptoms are not very serious, it is recommended that you don't take oxygen, so that you can adapt to the plateau environment more quickly. Mild altitude sickness will heal itself, so don't take oxygen easily to avoid dependence.

(4) Eat more carbohydrate and digestible food after entering Tibet; Drink plenty of water to keep enough water in the body; Dinner should not be too full. It is best not to drink or smoke. Eat more foods rich in vitamins such as fruits and vegetables.

(5). Pay attention to avoid excessive fatigue and eat regularly. A few days before you first arrive at the plateau, don't bathe frequently to avoid catching cold and catching a cold. Cold is often the main cause of acute high altitude pulmonary edema (it is not easy to recover under hypoxia) < P > (6). During the period of Tibet, it is not advisable to travel too frequently and to be overtaxed. When you first arrive at the plateau, you should not walk quickly, let alone run or do manual labor. After a week, you can gradually increase a certain amount of activity.
