In most cases, pneumonia does not leave any lasting effects, and the structure and function of the lungs can fully recover. However, pneumonia caused by Staphylococcus aureus, Klebsiella pneumoniae, or fungal infections may lead to necrosis, degeneration of lung tissue, and potentially the formation of cavities. Additionally, elderly patients or those with a long history of heavy smoking or chronic heart and lung conditions tend to have a poorer prognosis. Therefore, once clinical symptoms of pneumonia appear, it is crucial to seek prompt and appropriate treatment. During treatment, patients should ensure they get plenty of rest, avoid staying up late, and prevent overexertion to facilitate recovery. After recovering from pneumonia, patients should gradually incorporate exercise into their routine to strengthen their overall health.
