What causes coughing up blood? What causes coughing up blood

Common causes of coughing up bleeding are as follows:

1. Inflammation: upper respiratory tract infection causes damage to the throat mucosa, and capillaries rupture when coughing, causing a small amount of bloody sputum. In addition, severe cough caused by bronchitis can also produce bloody sputum, of which chronic bronchitis will cough up a mouthful of bloody sputum, but generally not more than 10-20ml;

2. Pulmonary tuberculosis: repeated hemoptysis with a course of more than 1-2 months;

3. Bronchiectasis: the course of the disease is long, but the patient's general condition is better, and CT examination can confirm the diagnosis;

4. Lung cancer: manifested as repeated coughing up of a small amount of blood in a short period of time, and the amount of hemoptysis rarely exceeds 100ml. X-rays and CT examinations can help with diagnosis;

5. Other reasons: such as blood diseases, bronchial vascular malformations, pulmonary embolism, such as pulmonary embolism manifested as sudden hemoptysis, chest pain, and dyspnea.

There are many ** that cause coughing up blood, and the common ones are as follows:

First, bronchiectasis, bronchiectasis is one of the common causes of hemoptysis, especially in the case of respiratory tract infection, which will lead to aggravation of hemoptysis symptoms in patients with bronchiectasis.

Second, lung cancer, patients with lung cancer often have hemoptysis, and even some lung cancer patients will have fatal hemoptysis, which is very critical, and it is too late to give rescue measures.

Third, pulmonary tuberculosis, patients with pulmonary tuberculosis accompanied by hemoptysis, is also relatively common; Patients with pulmonary tuberculosis often have low-grade fever in the afternoon, night sweats and other related symptoms.

Fourth, pneumonia, pneumonia is also a common cause of hemoptysis, although most patients with pneumonia do not have hemoptysis, but some patients with pneumonia will have hemoptysis. Since pneumonia is a disease with a relatively high incidence, although the incidence of hemoptysis for pneumonia itself is not high, pneumonia combined with hemoptysis can still be often encountered in clinical practice.

There are many causes of coughing up blood, and the common factors are tuberculosis, pneumonia, bronchiectasis and other diseases, all of which may cause patients to cough up blood. Coughing up blood is generally accompanied by frequent, coughing symptoms, severe patients may block the trachea because of blood clots, which is life-threatening, and most of the coughing up blood will be accompanied by viscous sputum, mostly dark red or pink in color. If it is a patient with tuberculosis and pneumonia, it will be accompanied by fever, chest pain and even dyspnea when coughing up blood, in order to avoid more complications caused by coughing up blood, the patient needs to go to the hospital in time for **, and check the chest X-ray, sputum smear and other examinations.

If it is due to bronchitis and other diseases, patients need to drink more drugs to moisten the lungs and suppress cough, and avoid smoking and drinking alcohol during the period of taking the medicine, and also need to pay special attention to diet.

There are many reasons, such as coughing up blood after smoking for a long time, or coughing up severe cough caused by laryngitis.

There are many reasons for this, as small as the respiratory tract because of long-term cough and bleeding, it is possible to have lung tumors, and esophageal tumors are also possible, so no matter how big or small, you must go to the hospital as soon as possible to check it out.

One of the reasons: If it is only a small amount of blood streaks or small blood spots in the sputum, and it is limited to one or two occasional times, there is no need to be nervous, as long as it is not a frequent coughing up of blood, it doesn't matter, what to do. Most of this bleeding is caused by small lesions in the mouth, nose, and throat, or by dry weather in autumn and winter, and has little clinical significance.

If you often cough up blood, or the amount of blood is large, you should pay attention to it, go to the hospital in time to find out**, and actively ** if there is a problem.

Reason 2: After severe pharyngitis, you can also bleed in the throat, you can cough up blood, after the bronchial inflammation is severe, the sticky hairs on the surface fall off, the capillaries are ruptured, you can cough up blood, and when the pneumonia is severe, there will also be this situation, but according to the symptoms, most of them are caused by throat inflammation, and other problems are generally long, and there are other symptoms, such as fever, chest tightness, chest pain, pants and other phenomena, but you can still go to a regular hospital for examination.

Reason 3: It is more common in tuberculosis, pneumonia, lung abscess, bronchiectasis, chronic bronchitis, heart disease and other diseases. After the symptoms of coughing up blood appear, on the one hand, it is necessary to bleed in time, and on the other hand, it is necessary to actively look for the cause of coughing up blood, go to the hospital for examination, and ** cause the disease of coughing up blood.

CT is needed.

Many people are also familiar with cough, because there will always be colds and illnesses in daily life, and cough is sometimes inevitable, but usually ordinary people only cough with phlegm, and generally speaking, they will not cough up blood, and if they cough up blood, the problem will often be slightly more seriousFor example, if you cough too severely, there will be blood, because when people cough too hard, it will cause the capillaries on the bronchi to tear, and then it will bleed, but the amount of bleeding is usually only a little bit, and the healing will generally be faster.

There is also pharyngeal inflammation, that is, we often say that the throat is inflamed, usually in this case, there will be blood when coughing, usually the general pharyngeal inflammation will not have the problem of coughing up blood, but if it is purulent tonsillitis, then there will be blood in the cough, and if you usually have chronic pharyngitis, then you have to go to the hospital to find the best way to deal with this, so that you can quickly relieve the symptoms; There is also a possibility that something is swallowed by mistake, especially for some children, if they swallow peanuts, erasers and other hard and large things, they will usually cough very badly, and at the same time coughingIf it is bloodshot, or even if it is severe, it can cause problems such as difficulty breathing, so you should seek medical attention in time.

The second thing is stomach bleeding, usually there are patients with severe stomach bleeding, not only when coughing with blood, but even when they are excreted, in fact, this situation is more caused by alcoholism, because if people drink too much, then it will lead to gastric bleedingTherefore, it is necessary to quit drinking in time, pay more attention to your rest time, and even if you want to improve your physical fitness, then you must also develop good living habits, so as to avoid such problems.

Finally, there are lung diseases, such as bronchitis, pneumonia, tuberculosis and other diseasesThen coughing up blood is also normal, but for such a situation, it is necessary to seek medical attention in time, so that the symptoms can be relieved faster.
