How Does a Stuffy Nose Develop?

Infection

Most people have had the common cold, which can sometimes lead to a sinus infection. A cold is caused by a virus, which makes your body release histamine. The virus is sometimes airborne, so any virus or other invader that enters the nose causes the histamine release. This histamine is what makes the tissue in your nose swell and become irritated. The membranes in the nose become clogged with blood, which leaves you with a lot of mucus that blocks the air passage. You can take over-the-counter or prescription decongestant medicine or antihistamine to help clear up the infection.

Allergies

Many people suffer from allergies. Pollen, certain animals, dust and even mold are common allergens. Sometimes these can be practically unavoidable, which makes it hard to control the allergies. When you breathe in an allergen, the tissue of your nose swells and histamine is released. This in turn causes congestion and watery mucus in the nose. Many people take prescription allergy medicine to achieve long-lasting effects. Depending on your allergy, you may be able to get away with taking medicine only when you come into contact with an allergen.

Nonallergenic Rhinitis

If you find yourself frequently suffering from a runny or stuffy nose, you may have nonallergenic rhinitis. Your blood vessels repeatedly swell, which stimulates the mucous glands, leaving you with a runny or stuffy nose. Various things that can cause this, including certain food, odors and even medication. Consult your doctor for treatment if you believe this to be the case for you.
