The two necessary conditions of alcohol allergy are allergic constitution and alcohol, and most allergic constitutions lack acetaldehyde dehydrogenase. Alcohol, that is, ethanol, is converted into acetaldehyde in the body. Because of the lack of acetaldehyde dehydrogenase in the body, it can no longer be converted into acetic acid and discharged to the outside world, which causes acetaldehyde poisoning and people will show various allergic symptoms. People who drink a lot of alcohol can be quickly converted because there are many enzymes in their bodies, and they will not get drunk without symptoms of poisoning. Edit this paragraph 2. Symptoms of alcohol allergy There are two kinds of symptoms of alcohol allergy: rapid onset and delayed onset. Rapid onset, the symptoms appear for a short time and are severe. In addition to redness and itching, there is also difficulty breathing caused by laryngeal edema. If the rescue is not timely, it can lead to death. There are few cases of rapid onset in clinic. There are many cases of delayed onset, which are generally manifested as itching all over the body after drinking, and red pimples and erythema appear all over the body or locally, lasting for one or two days. The symptom of alcohol allergy is that the back is itchy, and there are small red beans, accompanied by fever, or covered with erythema, which is unbearable. The reason for alcohol allergy is that these people are allergic, alcohol is an allergen, and contact with allergens will cause allergies. Other common clinical manifestations of alcohol allergy are skin symptoms, respiratory symptoms and digestive tract symptoms. Such as skin itching, eczema, urticaria, dizziness, nausea, vomiting, diarrhea, and even a few people will have anaphylactic shock. The latest research method, when the body has allergic reaction, will involve the heart, leading to vasodilation, rapid heartbeat, low blood pressure, increased burden on the heart, and the prominent symptom is arrhythmia. Edit this paragraph III. Conditions that lead to alcohol allergy Most people who are allergic to alcohol are allergic, and once the allergic constitution comes into contact with alcohol, various allergic symptoms will appear. Therefore, it is best for people with "alcohol allergy" to abstain from alcohol, because people with this constitution will deposit immune complexes in their internal organs for a long time, resulting in pathological changes. If you must drink alcohol, you can take drugs to clear away heat and toxic materials or warm yang in advance to relieve symptoms. 4. Prevention of alcohol allergy: Don't drink alcohol on an empty stomach, because alcohol is absorbed quickly on an empty stomach, and drinking alcohol on an empty stomach is harmful to the gastrointestinal tract, which is easy to cause gastric bleeding and gastric ulcer. The best prevention method is to eat edible foods, such as fat, hooves, etc. before drinking, or drink milk to protect the stomach by using the indigestible characteristics of fat in food to prevent alcohol from permeating the stomach wall. Don't drink with carbonated drinks such as cola and soda, because the ingredients in these drinks can accelerate the body's absorption of alcohol. As for drinking hot soup as much as possible after drinking, especially fish soup stewed with shredded ginger, which has a special hangover effect. Because alcohol is harmful to the liver, you should eat more green leafy vegetables when drinking, in which antioxidants and vitamins can protect the liver. You can also eat some soy products, of which lecithin has the function of protecting the liver. If someone drinks too much involuntarily, they can eat some fruits or drink some fruit juice afterwards, because the acidic components in fruits and fruit juice can neutralize alcohol. Many people often don't eat after drinking, which is more harmful. They should eat some digestible food, such as a bowl of noodles. Slow is better than fast. Ethanol can enter the blood five minutes after drinking, and the concentration of ethanol in the blood can reach the peak at 30-120 minutes. If you drink alcohol quickly, the concentration of ethanol in your blood will rise quickly, and you will soon have allergic symptoms. If you drink it slowly, the body can have enough time to decompose ethanol, and the amount of ethanol produced is less. Combination of food and drink. When drinking, it is best to eat pig liver. This is not only because of its rich nutrition, but also because pig liver can improve the body's ability to detoxify ethanol. People who often drink alcohol will lose vitamin B in the body, and pig liver is the most abundant food of vitamin B. Therefore, eating boiled pig liver or fried pig liver is an ideal accompaniment. Fruit for dessert. Eating dessert and fruit immediately after drinking can keep you in good condition. As the saying goes, "If you eat sweet persimmons after drinking, the smell of wine will disappear", which is true. Fruits such as sweet persimmons contain a lot of fructose, which can oxidize ethanol and accelerate the decomposition and metabolism of ethanol. Dessert also has a similar effect. Taking a hot bath after drinking can promote blood circulation, help metabolism, and make alcohol excreted with sweat. However, patients with hypertension and cardiovascular diseases should be careful of stroke after drinking and bathing, and should take a short rest first. Alcohol dehydrates cells in the body. Before going to bed, add plenty of water, and then add it again after waking up, which will help relieve the discomfort caused by dehydration. Drink more fruit juice or honey lemon juice, which not only supplements water, but also contains fructose, which can accelerate alcohol metabolism and slow down nausea symptoms. Eating a balanced dinner can supplement all kinds of lost essential nutrients; But eat lightly and don't eat fried or fatty food. After drinking the first cup, it will take 30 minutes to drink the second cup. If you want to drink the third cup, you must wait for an hour. But for the sake of your health, try not to reach for the fourth cup. Don't forget to add ice when drinking hard liquor. When you are hungry, tired or taking a bath, it is better not to drink for the time being. Never drink alcohol after taking medicine, especially after taking sleeping pills, sedatives and cold medicines.
