Hello and thank you for your question.
Believe it or not but runny nose while one is eating is one of the most common complaints and questions I hear in my practice. Usually the discharge is clear, there is no nasal congestion, no headaches, and symptoms are worse during eating. Somehow food smell triggers a response in the nose which causes runny nose.
Unfortunately no mater how many nasal sprays are tried, nothing really helps. There is a theory that watery eyes are actually due to the dryness and using artificial tears improves symptoms. I have suggested that my patients use saline nasal rinses as the same theory can apply to nasal symptoms. Sometimes it helps with symptoms, sometimes it doesn't.
If you have symptoms such as watery eyes, sneezing, coughing, then your symptoms can be related to allergies. Then, medications like Claritin or Zyrtec and a nasal steroid spray can improve your symptoms.
I hope you find this information helpful. If you need any clarification or have any additional questions, please let me know and I will be glad to assist you further.
