Once tuberculosis hemoptysis, not every day will be hemoptysis. Tuberculosis is an infectious disease of the respiratory tract caused by the bacterium Mycobacterium tuberculosis, which is a legally recognized category 2 infectious disease. It is mainly manifested by coughing, coughing up sputum with blood in the sputum, as well as fever, weight loss, malnutrition and other symptoms. If the cough and sputum are more than two weeks old and the sputum contains blood, tuberculosis should be highly suspected. Hemoptysis in pulmonary tuberculosis is generally less, mainly because the body is in a hypersensitive state, the permeability of the diseased capillaries increases, rupture after coughing, triggering blood in sputum, or pulmonary tuberculosis is combined with endobronchial tuberculosis, causing endobronchial hemorrhage. If the amount of hemoptysis is small, or if there is only blood in the sputum, it can be improved after two to three weeks of regular oral treatment with anti-tuberculosis drugs, such as isoniazid, rifampicin, pyrazinamide, and so on. In some cases, the amount of hemoptysis is large and may be life-threatening, so it is important to seek medical attention as soon as possible to stop the bleeding. Once the diagnosis of tuberculosis is confirmed, it is recommended to consult a doctor in time, complete the examination and cooperate with the doctor for scientific treatment. The above medication should be used in accordance with the doctor’s prescription.
