Repeated episodes of pneumonia may lead to decreased immunity, susceptibility to lung abscess and lung fibrosis. 1. Decreased immunity: Repeated episodes of pneumonia may cause the patient’s immunity to decrease, which makes the patient susceptible to infection-related diseases. 2. Lung abscess: If pneumonia is not effectively cured, purulent foci of infection may appear in the lungs, which is detrimental to the condition. 3. Lung fibrosis: repeated episodes of pneumonia can also lead to fibrosis in the lungs, which affects lung function and prevents the lungs from breathing and exchanging oxygen effectively, which will have a negative impact on the patient’s health. If pneumonia is recurring, it is recommended that the patient consult a hospital in a timely manner to identify the cause and follow the doctor’s instructions to actively treat the disease.
