What Causes a Runny Nose When Eating?
A runny nose when you eat, or gustatory rhinorrhea, is still something that is considered common, according to MayoClinic.com. If you develop a runny nose every time you eat specific foods, call your doctor to discuss the symptoms and treatment options. The runny nose may be a sign of another medical condition unrelated to eating. Common explanations for a runny nose while eating are a food allergy, the temperature of the foods and hay fever. A runny nose is treatable with diet modification and over-the-counter medications.
