Hi All,

I find in the last few weeks that I get a runny nose after eating a meal. I usually have a protien shake for breakfast so it does not happen then, usually once I start eating food. I notice it happens after I eat foods that have a few more carbs. I did not notice it until the last few weeks. I am currently 9 weeks out. Has anyone else had this happen? Could it be a food allergy or gluten sensitivity? Any feedback would help. I don't have a follow up until mid October.

I was just commenting to someone the other day that I get a runny nose when I eat. I have no idea why....just thought it was strange.

I vote for allergies!

I think I read on here that some people say that is their signal for being full.

The runny nose comes from the stimulation of the vagus nerve when our stomachs start to become full. The vagus nerve is a long nerve in the body that controls many functions, and this surgery seems to make some of our vagus nerves more sensitive. One of its jobs is to control gastric emptying and bowel motility. I noticed early on after I started eating more solid foods and had one too many bites, my eyes teared up, my nose ran and the hiccups would ensue. Usually when I get to that point it is too late (I have eaten too fast) and some of it comes back up. I really try hard now to eat more slowly so it doesn't sneak up on me. Not a pleasant feeling or result at all.

Anyway, if you google "vagus nerve and runny nose" you will find several websites about this phenomenon. This nerve also controls many other bodily functions, like heart rate, but too much to get into here. Anyone who wants more details can google "vagus nerve" and find a wealth of info. I am in the medical field, so I love that kind of stuff, but not everyone is so interested...Kathe

Some people sneeze too
