A few questions about altitude sickness. What to do if you have altitude sickness at high altitude?

Now is the best time to go to Lhasa, this time is the summer in Lhasa, and the chance of altitude sickness is relatively small. If you have altitude sickness, you can go to the hospital and don't worry too much. You can prepare some rhodiola before you go into Tibet.

Altitude sickness is a natural physiological reaction produced by the body to adapt to the changes in air pressure difference, low oxygen content, and dry air caused by altitude after reaching a certain altitude, and the altitude generally reaches about 2700 meters. The severity of altitude sickness varies from person to person, the first day of altitude sickness, the first day to rest well, the first two days to avoid strenuous activities and emotional excitement, the first 3-5 days to avoid bathing, especially hot baths, so as not to accelerate the circulation and exacerbate hypoxia, resulting in pulmonary edema. Try to exercise less, rest more, drink more water, eat more vegetables and fruits, and you can bring some anti-hyperreflex drugs with you, such as American ginseng lozenges, glucose, Omo blue tablets, etc.

Eat rhodiola a week in advance. Nordicam capsules (useful for relieving extreme fatigue), Baifuning (for controlling headaches caused by altitude sickness), American ginseng, American ginseng lozenges (useful for relieving extreme fatigue).

First of all, adjust your mindset and calm yourself. Consult your doctor and prepare some necessary medicines.

What to do after altitude sickness 1) If altitude sickness is relatively small, you can take the method of resting, drinking more water, exercising less, and resting for a period of time, the symptoms will disappear and weaken. 2) If you feel that the headache is severe and you have difficulty breathing, you can relieve the symptoms by inhaling oxygen. 3) If the reaction is more severe and affects sleep, you can take some to help relieve the symptoms.

For example, taking aminophylline, Gaoyuanan, Omo Blue Tablets, Baifuning, etc. 4) If altitude sickness has affected normal life, you should go to the local hospital for **, such as infusion, injection, medicine, oxygen or comprehensive**. 5) If altitude sickness has caused complications, you should leave the plateau area as soon as possible.

1. Sufficient thermal energy.

Of course, the determination of the amount of heat energy supplied depends mainly on the intensity of labor, and under the same conditions of labor intensity, people living in cold or plateau areas should supply about 10% more heat than people living in plain or warm areas. Among them, the protein supply should account for more than 10% of the total caloric energy, and it should contain high-quality protein. In cold areas, the fat content should be increased appropriately and sufficient vitamins should be supplied.

2. Adjust the number of meals to increase appetite.

One of the manifestations of altitude sickness is a decrease in appetite. In order to change this situation, we should try to diversify the preparation of meals in the morning, and pay attention to cooking techniques to make the color, aroma and taste good. At the same time, it is best to match the eating habits of the person who eats it.

When the appetite is good, do not overeat, so as not to increase the load on the digestive system, so that the digestive function decreases, when the appetite is poor, you can adopt a small number of meals diet system to maintain the total food intake. Hunger Ruler.

3. Abundant carbohydrates.

The carbohydrate content in China's diet is generally more than 60% of the total caloric energy, which is suitable for the requirements of people in plateau areas. In the supply of vitamins, special attention should be paid to the supply of sufficient vitamin C to promote the absorption of iron, and provide more foods with high iron content. Due to the decline in the appetite of people who have just entered the plateau, it is necessary to pay attention to the preparation of meals, ensure the best hot meals, the meals are delicious, and pay special attention to providing delicious soup to avoid greasy.

It has been found that carrots and apples can increase tolerance to hypoxia in the highlands.

4. Increase acidic foods.

In the case of hypoxia at the plateau, due to excessive ventilation, carbon dioxide exhalation increases, making body fluids alkaline, and alkalosis can occur in severe cases. Therefore, increasing the composition of acidic foods can regulate the acid-base balance and benefit the body. Acidic foods are foods rich in anions such as chlorine, carbon, sulfur, phosphorus, bromine, iodine, etc., which can form hydrochloric acid, carbonic acid and phosphoric acid in the body.

Acidic foods include meat, poultry, fish, egg yolks, cream, cheese, cereals, peanuts and walnuts.

Pay attention to the peculiarities of the food in cooking.

The atmospheric pressure of the plateau is low, and the boiling point of water is lower, so the heating time of all kinds of foods is prolonged, especially large pieces of meat, cabbage and beans. It has been reported that the cooking time of meat, rice and vegetables is reported to increase by an average of 10 to 15 per cent at sea level at an altitude of 1,000 metres above sea level and by 50 to 80 per cent at an altitude of 4,000 metres. Therefore, for foods that are not easy to cook, such as meat, it is necessary to chop them small and minced before cooking; Hard foods, such as dried beans, nuts, dried vegetables and cereals, should be soaked before preparation.

Choose canned food, such as canned meat, canned fish, canned vegetables, and canned meals, which are effective and simple measures, and some can be eaten by just a little heat. Of course, it would be better if you could use a pressure cooker to make meals.

If you have already reacted, you should start to eat more vitamin-rich foods such as vegetables and fruits, drink plenty of water, keep warm, take less baths to avoid colds and physical exertion, do not walk fast on the plateau, let alone run or run, do not overeat, do not drink alcohol and smoke. You can take some drugs to relieve altitude sickness: plateau rhodiola, Omo blue tablets, American ginseng lozenges, Nordic Kang capsules (very useful for relieving extreme fatigue), fast-acting Xingxin pills (not to take more), Danshen pills (**cardiovascular), glucose solution (the kind of five sticks in a box, take it when you have symptoms of altitude sickness have a certain curative effect) and so on.

For people with strong altitude adaptability, the symptoms of altitude sickness can be eliminated within 1-2 days, and those with weak adaptability can take 3-7 days.
