Is yellow sputum first followed by white sputum getting better?

Yellow sputum followed by white sputum is usually considered a sign of improvement.

Yellow sputum usually indicates bacterial infection or inflammation in the body and may be accompanied by pus production. As treatment progresses and the body recovers, yellow sputum gradually changes to white sputum, which may mean that the infection is under control, inflammation is decreasing, and sputum is gradually becoming clearer. However, whether the disease is really improving needs to be considered in conjunction with the improvement of other clinical symptoms and signs, and is best evaluated by a doctor. Therefore, during the treatment period, we should pay close attention to the changes in the condition and adjust the treatment plan in time to achieve better treatment results.
