The manifestations of pulmonary tuberculosis are diverse, mainly characterized by systemic symptoms and respiratory symptoms. The most common systemic symptom is fever, which is low in the afternoon, usually starting to rise in the afternoon and falling to normal in the morning of the next day. Some patients also experience chronic wasting such as fatigue, loss of appetite, night sweats and weight loss. Respiratory symptoms include cough and sputum, and blood in sputum. Coughing is usually mild, and sputum volume may increase when a TB cavity is formed. Hemoptysis is present in about 1/3 of patients. When TB involves the pleura, pleural effusion, dyspnea and chest pain may occur. If tuberculosis is diagnosed, patients should actively consult a doctor and receive regular anti-tuberculosis treatment according to the doctor’s instructions, so as to avoid recurrence of the disease, which may affect the prognosis.
