In a nutshell
In some people, clear fluid runs from the nose during a hot or spicy meal. This gustatory rhinitis is a non-allergic reflex and usually subsides quickly after eating.
Why does it happen?
Irritants in food activate sensory nerves. Reflex pathways stimulate glands in the nasal lining, producing thin fluid without requiring an allergic immune response.
Frequency
A runny nose while eating affects only some people. Its frequency depends, among other things, on age and type of food; no single rate is given here.
Frequency is a qualitative description, not your individual probability.
Is it normal?
Brief clear nasal discharge only while eating is often harmless.
When to seek advice
Swelling of the lips or tongue, shortness of breath, or circulatory problems after eating: call emergency services immediately; this does not fit simple gustatory rhinitis.
