Nasal congestion or "stuffy nose" occurs when nasal and adjacent tissues and blood vessels become swollen with excess fluid, causing a "stuffy" feeling. Nasal congestion may or may not be accompanied by a nasal discharge or "runny nose."

Nasal congestion usually is just an annoyance for older children and adults. But nasal congestion can be serious in infants, who might have a hard time nursing or breathing as a result.
