Symptoms of bad lungs

The clinical symptoms caused by poor lungs are related to the specific condition of the patient. For example, normal pulmonary fibrosis will show symptoms of cough and chest tightness, and even some patients can cause severe respiratory failure. For example, COPD is often manifested as chronic and progressive chest tightness and dyspnea symptoms, which can also be accompanied by cough and expectoration. For example, bronchial asthma may show symptoms of paroxysmal cough, chest tightness and wheezing, tuberculosis may show symptoms of low fever in the afternoon, night sweats, hemoptysis, weight loss, etc. Patients with pneumonia may show acute fever, cough and expectoration. Patients with lung cancer may exhibit chest distress, hemoptysis, hoarseness, weight loss, and even early lung cancer may not exhibit any clinical symptoms.
