Why does eating give me a runny nose?
Having a runny nose after eating is usually associated with eating spicy food, but there are many other reasons that your nose can run while eating. Some have nothing to do with the type of food but instead are symptoms of other conditions.
The medical term for a runny nose is rhinitis. A person’s nose might run after eating because they have food allergies, which is called allergic rhinitis.
If a person’s nose runs without their having a food allergy, this is called gustatory rhinitis, which is a type of non-allergic rhinitis.
This article discusses the many causes of a runny nose while eating.
A person’s nose might run after eating if they have allergic rhinitis caused by a food allergy.
A person may experience a runny nose and other symptoms either after eating a particular kind of food or, in some cases, after eating any food.
A runny nose may be accompanied by the following symptoms:
- a stuffy, congested feeling in the nose
- postnasal drip, or excess mucus in the back of the throat
Some people may experience a runny nose due to the food they ate, a food allergy, seasonal allergies, and other causes. Read on for a list of possible causes for a person to experience a runny nose after eating.
When a person’s nose runs after eating without any other symptoms of an allergic reaction occurring, this is referred to as gustatory rhinitis.
Gustatory rhinitis affects many people after they eat hot or spicy foods. When a person eats these foods, a nerve called the trigeminal sensory nerve is stimulated, which causes the nose to run.
A person may prevent gustatory rhinitis by avoiding trigger foods. If their nose runs after eating any food, they can take certain medications to manage their symptoms. One such medication is topical intranasal atropine.
Allergic rhinitis is a condition affecting up to 60 million people within the United States. People can experience it seasonally or all year round.
Typically, an environmental trigger can trigger symptoms, such as dust mites, pollen, or pet dander. Some people may have this kind of allergic reaction to certain types of food.
Allergic rhinitis can cause the following symptoms:
- a runny or stuffy nose
- itchy eyes, mouth, throat, or skin
- dry eyes
- watering eyes
