Tuberculosis can cause dyspnea, when patients with tuberculosis have dyspnea, it mostly suggests that the degree of infection of tuberculosis is more serious or there are corresponding complications, for example, acute cornual tuberculosis, caseous pneumonia, patients can have different degrees of dyspnea, mostly due to the seriousness of the lung infection, which triggers patients to appear chest tightness, shortness of breath symptoms. Dyspnea can also occur when tuberculosis patients suffer from secondary atelectasis, massive tuberculous pleural effusion, or severe pneumothorax due to the destruction of lung tissues.
