Postnasal Drip — What it is and How to Treat it
Postnasal drip happens when excess mucus from your nose builds up and drips down the back of your throat. Mucus gets a bad rap, but in fact, a certain amount of it is healthy. You probably don't even notice it, but your body constantly makes mucus every day to moisten your nasal lining, trap and clear irritants you inhale, and to help fight infections.1 However, when your normal mucus production shifts into overdrive causing postnasal drip, that’s your body’s way of responding to a cold, allergy, or another irritant. While it can be bothersome, postnasal drip often goes away on its own.2 If you have other symptoms along with postnasal drip or experience it repeatedly or for a prolonged time, talk to your healthcare provider.
What Causes Postnasal Drip?1
It may occur for many reasons, but the common cause of postnasal drip is allergies—called allergic postnasal drip.
Other typical causes include:
Colds and flu — they can increase the chances of postnasal drip
Sinus and bacterial infections — when nasal cavities become inflamed
Changing weather and dry air — the body may create more mucus to moisturize nasal passages
Bright lights — may trigger the body to produce excess mucus
Spicy foods — can aggravate non-allergic sinus attacks
Deviated septum — when one nasal passage is smaller than the other, it can adversely affect the sinuses
*Ask your doctor before using any products to treat postnasal drip while pregnant or breastfeeding. Use products only as directed on label when treating postnasal drip.
