Does the change of nasal discharge from clear to yellow indicate improvement?

Nasal discharge changing from clear to yellow is not necessarily a sign of improvement. This change may be caused by various factors, including the common cold, allergic rhinitis, and sinusitis. In the early stages of a cold, patients typically experience clear nasal discharge, which helps flush pathogens from the nasal passages. As the illness progresses, the discharge may turn yellow if a secondary bacterial infection develops. At this stage, additional symptoms such as worsening nasal congestion, headache, and fever may appear, indicating possible deterioration of the condition or the emergence of complications like sinusitis. When nasal discharge changes from clear to yellow, it should not be simply interpreted as a sign of recovery. Instead, one should monitor changes in symptoms and seek timely medical attention when necessary, following the physician's instructions for treatment. During treatment, antibiotics or other medications may be used to combat bacterial infection, while maintaining adequate hydration and rest is essential to promote recovery.
