Distinguishing the blood in the lungs and throat

Some patients with throat diseases, although they have had ulcers for a long time, have never had severe pain, only mild pain. When the pain comes, the patient should remain calm and endure it, and the sore throat will go away. This type of patient rarely seeks medical treatment or takes medication, so if they bleed, they do not feel much pain. Once vomiting blood occurs suddenly, the patient does not know whether the blood comes from the lungs or the throat. So, how do you tell whether it is pulmonary bleeding or throat bleeding?

The amount of blood in the throat is very small, but the amount of blood in the lungs is always large. When vomiting blood from the lungs, the blood comes out of the trachea, and symptoms include coughing and itchy throat. At the same time, the lungs contain oxygen, so the blood is mostly bright red and contains foam. The vomited blood is often mixed with sputum. When vomiting, it is like coughing and spitting. The throat often feels itchy and blood is coughed up. Sometimes there is blood in the sputum, and symptoms such as dry mouth and throat, palpitations, hot face, chest tightness and rib pain are also seen. This is caused by damage to the lung network.

When vomiting lung blood, the large collaterals in the lungs are damaged and the blood comes out from the esophagus. The color is often ochre or purple-black, because lung bleeding may remain in the stomach and is sometimes vomited out in lumps. If he continues to vomit, there will be a lot of blood, filling up a basin, a bowl, or even a bowl. If you look closely, you may see broken rice food. When vomiting, the patient will have pale face, dizziness, shortness of breath, irritability, side pain, dry mouth and internal heat, which is a very dangerous condition. However, it is easier to treat than pulmonary hemorrhage. Because after throat bleeding, it is not difficult to cure as long as you take proper care of it. After pulmonary hemorrhage, the root of the disease remains and it is difficult to heal quickly. Therefore, after a small amount of pulmonary hemorrhage, one should be slightly optimistic. However, if the patient vomits for the second or third time and the blood keeps surging and there is a risk of fainting, that is a serious condition.

Some patients with throat bleeding may only vomit a small amount, but according to statistics, this situation is very rare. Ancient Chinese books pay great attention to identifying the source of vomiting blood and distinguishing between lung blood and throat bleeding. Because the pathogens and treatments of the two types of vomiting blood are completely different.

Ancient books believe that pulmonary hemorrhage is "damage to the large collaterals of the lungs." The so-called "large collaterals" refer to the large blood vessels. Because one of the blood vessels attached to the stomach is very large, after it ruptures, a lot of blood will come out. When it is vomited out, the blood rushes up violently, filling the mouth with blood, and even flows out of the nostrils. In some cases, a dozen mouthfuls of blood may be vomited out, while in some cases, a whole bowl or a full bowl may be vomited out. After vomiting, the face and lips turn pale, cold sweats run down, and the person feels dizzy and dazed, just like the fainting state that occurs when the heart is weak. In ancient Chinese books, lung bleeding is divided into "damage to small collaterals" or "injury to sun collaterals". The so-called small collaterals are small blood vessels. The so-called Sunluo refers to the tiny blood vessels. Therefore, the blood that comes out of the lungs is mostly just a tiny amount, or a few mouthfuls.

Pulmonary hemorrhage is severe. Not only does the blood come out of the mouth, but some of the blood remains in the stomach and passes through the large and small intestines and comes out in the feces, turning the feces into a black and congested mass. Traditional Chinese medicine does not confuse stomach blood or lung blood, and the most detailed distinction is made before diagnosis and treatment. The Qianjin Yaofang states: “Heat accumulation and vomiting of blood is caused by heat accumulation in the blood, which leads to disorderly behavior… The blood vomited due to stomach injury is red, with abdominal cramps and spontaneous sweating.” The Jinkui Yi states: “Heat accumulation and vomiting of blood is caused by overeating and drinking, which makes the stomach uncomfortable, and blood is vomited with vomiting…Heat accumulation and vomiting of blood, the blood comes out of the mouth and nose, and the force is like a gushing spring, with heat on the diaphragm, fullness and pain in the chest, a strong and long pulse, and a strong pulse when pressed, and the spirit is not tired, or the blood is purple and black.”
