Understanding Gustatory Rhinitis: Why Your Nose Runs While Eating
Medical experts explain why many people experience a runny nose during meals, a condition known as gustatory rhinitis.
According to a report by Khaosod Online on August 17, 2026, many individuals frequently experience a runny nose while eating. Medical professionals identify the primary cause as 'gustatory rhinitis,' a form of non-allergic rhinitis that often becomes more prevalent with age.
When we eat, the body naturally stimulates saliva production to aid digestion. In some people, this process inadvertently triggers nerves in the nasal area, causing the mucous membranes to produce excess clear fluid. This is particularly common when consuming spicy foods. Unlike typical allergies, this condition usually occurs without symptoms like sneezing, itchy eyes, or nasal congestion.
For residents and travelers in Thailand, it is important to distinguish this common reaction from other health issues. While gustatory rhinitis is generally benign, persistent symptoms that interfere with daily life may warrant a medical consultation. Experts advise seeking professional care if you notice chronic congestion, a loss of smell, difficulty breathing through the nose, or if the nasal discharge changes color or contains blood.
Crucially, if clear fluid flows continuously from only one nostril—resembling a leaking tap—medical attention should be sought immediately. While rare, this can be a sign of a cerebrospinal fluid leak. As this information is for educational purposes, those concerned about their symptoms should consult a qualified healthcare provider for a proper diagnosis.
