The clinical manifestation of dyspnea in pulmonary tuberculosis may be due to the following reasons: 1. Pleural effusion may occur. If a patient with pulmonary tuberculosis causes tuberculous pleurisy, pleural effusion can occur, and a large amount of pleural effusion can cause dyspnea. If the patient’s thoracic percussion is solid, pleural effusion is very likely, and pulmonary CT examination needs to be improved. If the patient’s lung CT indicates a large amount of pleural effusion, thoracentesis may be considered to relieve the symptoms.2. Severe lung destruction can present with dyspnea, and if the patient has dyspnea due to lung destruction, active anti-tuberculosis treatment should be administered first. Severe pleural hypertrophy can also present with dyspnea, and surgical treatment can be considered at this time. In addition, patients with chronic tuberculosis or tuberculosis that is not actively treated may have chronic pulmonary heart disease as a complication and may also have dyspnea.
