Tuberculosis is a chronic infectious disease. Tuberculosis is a respiratory infection caused by infection with Mycobacterium tuberculosis. The common clinical symptoms of tuberculosis are coughing and coughing with blood in the sputum, or coughing up blood, fever, malaise, night sweats, and emaciation. Coughing up blood is a common symptom of pulmonary tuberculosis. If a small amount of blood is coughed up, aminocaproic acid injection and phenolsulfonamide injection can be applied to stop the bleeding. If a large amount of blood is coughing, posterior pituitary preparations can be used. If conservative medical treatment is ineffective, surgical treatment can be considered. If anti-tuberculosis treatment is reasonable and standardized, the prognosis is generally good and can be cured. The symptoms can gradually subside after 2-3 weeks of treatment. However, if left untreated, it may cause permanent damage to the lungs, which may later lead to decreased lung function and symptoms of shortness of breath after activity.
