Runny nose after eating

1. Gustatory rhinitis. This is a condition in which people sneeze, get a watery nose or become congested after eating. Any food can be a trigger, but most often it is caused by hot, spicy foods or alcohol. Cold foods can also trigger a series of sneezes, which in the case of gustatory rhinitis is a neurogenic reflex mechanism (it originates in the nervous system).
2. Food-related sneezing can also be caused by eating large meals, as sneezing has been attributed to a distended stomach.

Yep,

I'm 11 months out and still get the runny nose.  But it usually hits me if I eat anything made of wheat or potatoes.  And of course, I get a runny nose if I eat too much. 

Also, if my nose runs very much it usually signal that I am going to throw up.  

I have lost 200 lbs and I am out 35 months and loving it. I do get runny noses
when I'm full although it stopped for a year and is now back? whats that about?
I also used to sneeze when I was full (20 was my average) but that has seemed to subside.
no logic to any of this but I'm so happy with the new look I dont care about these little problems.

 Reactive Hypoglycemia. (Maybe) 

 look up Reactive Hypoglycemia, it may be your underlying problem because i have the same problem. 

 but anyway if you find out anything more please let me know so i can fully determine what im dealing with. thank you. :) (Reactive Hypoglycemia) 

I am 10 months post op RNY and once I started eating solid foods the nose started running EVERY time I eat...I have read comments about it being when your full, but it happens to me once I put one bite into my mouth...does not matter what it is...but I have found that when its real bad I usually end up throwing up, mostly that foamies and phlem.. I get this no matter how soft or how much I chew...once its gone I can usually try eating again...but sometimes depending on what it was, my stomach will say no way your not having that today maybe tomorrow lol....Anyone find that happening also? like you can eat something one day but not the next or visa versa cant eat it today but you cant  another day?

Abstract

BACKGROUND:
Gustatory rhinitis is a type of nonallergic rhinitis that is usually associated with ingestion of hot or spicy foods. Characteristics of this condition and its impact on food choices have not been studied.

OBJECTIVE:
To survey individuals regarding causative foods, association with atopic conditions, and food avoidance behaviors for gustatory rhinitis.

METHODS:
An original, self-administered questionnaire was distributed to children and adults who were seen in a busy outpatient dermatology clinic. Atopic history, frequency of rhinorrhea after food ingestion, intake of foods associated with gustatory rhinitis, symptom severity, and food avoidance were evaluated

.
RESULTS:
Of the 571 participants who completed the survey, 396 (69%) indicated at least 1 food resulted in gustatory rhinitis symptoms. Patients with allergic rhinitis (P < .001) and a history of smoking (P = .049) were more likely to have experienced gustatory rhinitis. Bread (6%) and hot chili peppers (49%) represented the least and most common foods identified, respectively. A total of 65% of patients who experienced gustatory rhinitis never avoided the causative food, whereas 46% were never bothered by their symptoms. Patients *****ported more causative foods were also more likely to use medications before eating to lessen their symptoms (P = .03).

CONCLUSION:
The results presented herein suggest that almost all foods can be implicated, both children and adults develop this condition, and patients with a history of allergic rhinitis or smoking are more likely to report gustatory rhinitis symptoms. Most patients though do not avoid the causative food(s) and are not significantly bothered by symptoms.

That was always my signal to stop eating!  Pressure on the vagus nerve.

I am almost 4 years out and this only started with me about 6 months to a year ago.  Once I am full or over eat, my nose runs terribly.  It's very annoying and I can't figure out why it happens.  It never happened to me before at all, and nobody I know has ever experienced it either.
