Coughing up some blood

The phenomenon of coughing up blood is clinically called hemoptysis. The factors that lead to coughing up blood are very complex, most of which are caused by diseases, and some may also be caused by trauma. Therefore, when coughing up blood occurs, especially if it happens frequently, it is necessary to find out the situation as soon as possible and receive treatment. First, let’s understand the main reasons. So, what are the reasons for coughing up blood? Let’s take a look below.

Diseases that cause hemoptysis are not limited to respiratory diseases, although respiratory diseases are more common. The following are various disorders that can cause hemoptysis.

1. Respiratory diseases

Such as pulmonary tuberculosis, bronchiectasis, bronchitis, lung abscess, lung cancer, pneumonia, paragonimiasis, pulmonary amebiasis, pulmonary echinococcosis, pulmonary fungal disease, pneumocystis carinii, bronchial stones, lung metastatic tumors, pulmonary adenoma, silicosis, etc. These inflammations lead to increased permeability of bronchial mucosa or lesion capillaries, or rupture of submucosal blood vessel walls, causing bleeding.

2. Circulatory system diseases

Common ones include rheumatic heart disease, mitral stenosis, hypertensive heart disease, pulmonary hypertension, aortic aneurysm, pulmonary infarction and pulmonary arteriovenous fistula.

3. Trauma

Chest trauma, contusion, rib fractures, gunshot wounds, explosion injuries and medical procedures (such as chest or lung puncture, biopsy, bronchoscopy, etc.) can occasionally cause hemoptysis.

4. Systemic bleeding tendency disease

Common ones include leukemia, hemophilia, aplastic anemia, pulmonary hemorrhagic leptospirosis, epidemic hemorrhagic fever, pulmonary plague, thrombocytopenic purpura, disseminated intravascular coagulation, chronic renal failure, uremia, etc.

5. Other less common diseases or abnormalities

Such as alternative menstruation (no vaginal bleeding), oxygen poisoning, Goodpasture's syndrome, bronchiectasis, sinusitis, and visceroposition syndrome.
