Limiting emphysema, that is, emphysema formed by localized alveolar rupture of the lungs, is irreversible and can be alleviated, but not cured. Limiting emphysema is a lesion caused by repeated chronic inflammation. If there are no symptoms such as severe dyspnea, coughing, cyanosis, etc., the condition is relatively mild, and there is no impairment of lung function, treatment is usually not required. If there is a complication of infection and symptoms such as coughing and sputum are present, relevant treatment is required. There are many causes of restrictive emphysema, such as chronic lung infections, long-term smoking, air pollution, occupational dust, allergies and so on. There is no good clinical cure for restrictive emphysema, but the main focus is to treat the cause and symptoms, alleviate the patient’s condition and improve his lung function. After suffering from emphysema, you must pay great attention to it and go to the hospital in time to avoid further progression of the disease.
