Postnasal drip is a common condition that occurs when excess mucus drains from the sinuses down the back of the throat. It can be caused by allergies, colds, sinus infections, or even changes in the weather. While it’s often associated with a sore throat, coughing, or a constant need to clear your throat, many people also experience nausea. But how exactly does postnasal drip cause nausea and what can you do to find relief? Keep reading to learn more!

How Does Postnasal Drip Lead to Nausea?
When mucus drips down the back of your throat, it can irritate the lining of your esophagus and stomach. This can lead to nausea in a few different ways:
- Swallowing Excess Mucus: As mucus builds up, you may unconsciously swallow it throughout the day. This can upset your stomach, leading to nausea or even vomiting in severe cases.
- Throat Irritation: The constant presence of mucus can cause gagging or an increased urge to cough, which can trigger nausea.
- Acid Reflux Connection: Postnasal drip can contribute to acid reflux by increasing throat irritation, which may lead to heartburn, indigestion, or nausea.
- Inner Ear Imbalance: If postnasal drip is caused by sinus congestion, it can sometimes affect the inner ear, leading to dizziness or nausea.
Other Symptoms That May Accompany Nausea
If your nausea is related to postnasal drip, you may also experience:
- Frequent throat clearing
- Coughing, especially at night
- Hoareness or a sore throat
- A feeling or mucus stuck in your throat
- Sinus congestion or a runny nose
- Mild dizziness or headaches
How To Relieve Postnasal Drip and Nausea
Since nausea from postnasal drip is typically caused by mucus buildup and throat irritation, managing the underlying cause is the best way to find relief. Be sure to stay hydrated by drinking plenty of water to thin mucus and prevent buildup in your throat. Use a saline rinse to help clear out excess mucus and allergens. If allergies are the cause, over-the-counter antihistamines can reduce postnasal drip and prevent nausea. Additionally, you can try using a humidifier to prevent throat irritation, avoiding irritants, and eating small, light meals.
While postnasal drip is usually mild and treatable at home, you should seek medical attention if you experience severe or persistent nausea, vomiting that lasts more than 24 hours, and symptoms that last longer than a week.
