10 views

Yellow snot is most commonly associated with an infection, such as a cold or sinus infection. While allergies can also cause nasal discharge, it is typically clear and runny. Yellow snot indicates that your immune system is fighting off an infection and producing white blood cells, which turn yellow when they die and mix with nasal mucus. If you experience other symptoms like fever, facial pain, or persistent congestion, it's wise to consult with a healthcare provider for proper diagnosis and treatment.
