The symptoms of nasal congestion in children are clinically considered to be caused by upper respiratory tract infection, rhinitis attack and some physical factors.

First of all, children with upper respiratory tract infection will have symptoms of nasal congestion, which is often referred to as a cold, in addition to runny nose, sneezing and coughing symptoms. Before the child develops further symptoms, such as fever, he or she can take oral cough syrup or oral Chinese medicine such as pediatric cold granules to treat the symptoms. During the period of oral medication, it is important to drink more water, rest regularly, do not overexert yourself, and avoid going to crowded places to avoid cross-infection.

Finally some physical factors can also lead to occlusion in children, for example, children are more naughty will be stuffed in the nose to cause nasal congestion, but this situation is relatively rare, but can not be ruled out.
