What Causes Post-Nasal Drip

Post-nasal drip is a steady stream of mucus draining down the back of your throat. It is a symptom of many different illnesses and conditions. Some of the most common causes of post-nasal drip include seasonal allergies and colds. However, any condition that leads to a runny nose is likely to cause post-nasal drip to occur. Post-nasal drip is a harmless symptom that will resolve with your other symptoms, however, it can cause irritation in the throat.

How to Diagnose Post-Nasal Drip

Post-nasal drip is often a result of other symptoms, including congestion or a runny nose. When excess mucus is produced in response to an irritant, the mucus needs to escape the sinuses. Running down the back of your throat into your stomach is an easy way to get rid of the mucus when your nose is too clogged up. If you have post-nasal drip, you probably can feel the tickle in the back of your throat, which makes it easy to diagnose.

Treatment Options for Post-Nasal Drip

Post-nasal drip is the result of other symptoms, which means that it can be difficult to treat. In fact, there is no direct way to address post-nasal drip. However, if you notice you’re experiencing post-nasal drip and are in need of rapid relief, targeting symptoms in the sinuses like congestion, runny nose or sinus pressure can help get rid of post-nasal drip. In most cases, post-nasal drip is a sign that mucus is able to freely leave the sinuses, which means that you are unlikely to develop complications like sinus infections.
