You are not alone. From fiery curries to chilli snacks, spicy dishes can trigger an unexpected nasal reaction, even when you are not suffering from a cold. But why does this happen, and what goes on inside your body when you eat something spicy? In this edition of ‘Everyday Explained,’ HT Lifestyle spoke to Dr Sumit Kumar Gaur, Senior Consultant in ENT, Apollo hospital, Bannerghatta road, to understand the science behind this.
Because it often leaves you with a runny nose, do you also love spicy food but avoid it.
It is a form of non-allergic rhinitis in which the nose produces excess watery mucus in response to certain foods, particularly those containing chilli, pepper and other pungent spices. Unlike an allergic reaction, this response is generally triggered by sensory nerve stimulation rather than an immune response to a food allergen. Their activation sends signals through the nervous system , producing the familiar burning sensation associated with spicy food. In susceptible individuals, this stimulation also triggers reflex responses that increase mucus secretion in the nose, resulting in a watery discharge. “Chilli is not the only trigger. Temperature may also play a role, as very hot foods can stimulate sensory pathways and increase nasal secretions. However, the response varies considerably between individuals. Some people may experience pronounced nasal discharge after eating even mildly spicy food, while others can tolerate very spicy meals without any symptoms. Gustatory rhinitis is generally harmless and does not mean that the person has an allergy to chilli or that their body cannot tolerate spicy food. The main distinction is that gustatory rhinitis typically causes clear, watery nasal discharge during or shortly after eating, without symptoms such as widespread itching, hives, facial swelling or breathing difficulty. If these other symptoms occur, an allergic reaction or another medical problem must be considered.
A runny nose while eating spicy food is a condition known as gustatory rhinitis, according to Dr Gaur. Hot mustard, horseradish, black pepper and other pungent ingredients can produce similar effects in some individuals,” said Dr Gaur.
