Does Acid Reflux Cause Nasal Congestion?

Yes, acid reflux can sometimes cause nasal congestion or a sensation of having a stuffy nose. This occurs due to the backflow of stomach acid into the esophagus, which is known as gastroesophageal reflux disease (GERD).

GERD can lead to a condition called laryngopharyngeal reflux (LPR), which involves the reflux of stomach contents, including acid, up into the throat, and sometimes reaching the nasal passages. When stomach acid travels up the esophagus and into the throat, it can irritate the tissues in the back of the throat and affect the nasal passages, leading to symptoms such as:

  • Postnasal drip: Acid reflux can trigger the production of mucus in the throat and nasal passages, leading to a sensation of mucus dripping down the back of the throat, causing congestion or a runny nose.
  • Inflammation and irritation: The acid irritates the tissues in the throat and upper airway, causing inflammation. This inflammation can extend to the nasal passages, resulting in nasal congestion or a feeling of blockage.
  • Sinus irritation: Refluxed stomach contents can sometimes reach the sinuses and irritate them, leading to congestion or a feeling of sinus pressure.

It’s essential to note that while acid reflux can contribute to nasal congestion or related symptoms, other conditions such as allergies, sinus infections, or non-acid reflux (where non-acidic contents from the stomach reflux) can also cause similar nasal symptoms.

If you experience chronic nasal congestion along with acid reflux symptoms, consulting a healthcare professional, such as an otolaryngologist (ear, nose, and throat specialist) or a gastroenterologist, can help determine the underlying cause and appropriate treatment. Management often involves lifestyle changes, dietary modifications, medications, and in some cases, further evaluation or testing to address both the reflux and nasal symptoms effectively.
