Causes of Runny Nose

Runny nose is medically known as rhinorrhea and refers to excessive secretion of fluid from the nasal mucosa. This fluid can be clear, transparent, yellow or green. A runny nose is a response to a variety of factors, including viral, bacterial or allergic infections. The nasal mucosa helps trap and protect the body from foreign substances and pathogens in the air.

Excessive mucus secretion is usually a response to irritation or inflammation of the nasal mucosa.
