Chinese medicine believes that nosebleeds are caused by the upward movement of one's qi and blood. The nose belongs to the orifices of the lungs, and illnesses in the nose generally have a great deal to do with abnormalities in the lungs and liver. When a person's qi and blood rise, especially when the lung qi is hotter, a person will have a nosebleed. When the Lung Qi is too hot, a person will also have blood or bleeding under the eyes. The causes of fire and nosebleeds are the same, both are the result of Qi and blood rising, but fire is not the cause of nosebleeds. When the nasal cavity is too dry, the capillaries inside will rupture, resulting in bleeding. From the clinical point of view, 90% of the nosebleed phenomenon belongs to the blood vessel rupture caused by vascular bleeding. Patients do not need to be too nervous about this, most cases can be treated on their own, and timely bleeding can be stopped. When the nose bleeds, you can use a cotton ball to block the nose, and the head can be tilted back in order to stop bleeding as soon as possible. At the same time, a cool towel can be applied to the forehead or nose to lower the temperature of the head and nose to reduce the bleeding symptoms. If there is too much bleeding in the nose and it is hard to stop, it is time to see a doctor. Nosebleeds in young people are also related to exertion and exercise. Especially young people love sports, often when they are exercising, their noses suddenly start to bleed. Normally, these bleeding symptoms, patients can stop bleeding by themselves. However, without warning, sudden nosebleeds are best to go to the hospital to do a checkup, early exclusion of nasal tumors and other lesions. In general, nasal blood vessel rupture bleeding does not need special treatment. Prof. Yang Li said that since nosebleeds are related to lung heat, people should try to avoid situations that cause lung heat in their diet and life. Drink less alcohol, eat less spicy food, and eat less food that may generate heat. Instead, one can eat more foods that clear heat and reduce fire such as bitter melon, green bean soup, watermelon, and cold drinks. Take 3 grams of winter mulberry leaves, plus white grass root and maitake, and then add some licorice, used to brew water to drink, you can achieve the purpose of clearing heat and lowering fire. Nosebleed, medically known as "epistaxis", mostly due to "lung dryness and blood heat", caused by nasal dryness, capillary toughness is not enough, rupture caused. If not treated in time, delayed development, will produce serious consequences, such as nasal mucosa atrophy, anemia, memory loss, poor vision, decreased immunity, and even cause ischemic shock, life-threatening. Children are active and often hurt their noses unintentionally, resulting in nosebleeds. They may also insert foreign objects into their nostrils out of curiosity, causing damage to the nasal mucosa. These situations can happen at any time and the amount of blood that comes out is very small, so there is no need to worry too much. As to why nosebleeds are particularly serious in winter, it is mainly because we like to eat steaming hot food in cold weather. When eating, the gusts of hot air will cause the blood in the nasal cavity to speed up, and if the mucous membrane of the nose is naturally thin or has been injured before, it will be easy to get a nosebleed. In addition, in a cold and dry environment, we need more blood to flow through the nasal cavity to raise the temperature and humidity, and the microfilament blood vessels in the nasal mucous membrane will easily become congested, resulting in nosebleeds. From the perspective of Chinese medicine, the causes of nosebleeds can be categorized into dryness, heatiness and weakness. If you have frequent nosebleeds and also suffer from allergic rhinitis with yellow or green nasal discharge, or if your lips are often red and you have bad breath, then you are very hot and dry. First of all, of course, we have to clear the heat, and more importantly, we should not let him eat too much flavorful food on weekdays. Snacks such as chocolates, cookies, French fries, etc., are also very hot and should be eaten as little as possible. Treatment of nosebleeds in adults: 1. Blow out the blood clots before stopping the flow, so as not to prevent the bleeding from stopping due to the inability of the wound to close. 2. Moisten cotton with decongestant or nasal spray and stuff it into the nostril to help stop the bleeding, white vinegar will also work. 3. Pinch part of the nasal meat with your fingers and keep pressing for five to seven minutes to help stop the bleeding. 4. Sit up straight to prevent blood from flowing down your throat. 5. Ice compresses can encourage blood vessels to constrict and reduce bleeding. 6. After the blood has coagulated, a blood clot will form a scab. At this time, it is best not to dig your nostrils, so as not to peel off the scab and cause the nosebleed to recur. 7. Apply antibiotic or steroid ointment to stop the itching and prevent the mucus from drying up. 8.
