The "Full Sleeve Sneezys" & the Vagus Nerve - A Scientific Explanation
At long last (excerpted from a post on the main forum, which borrowed from an article posted on the "Quixotic Weight Loss Surgery" website):

How does this effect or associate with Bariatric Post-Op patients?
Signals from the Stomach are "distorted somewhat"
and often Disrupted or damaged by the Gastric Bypass.
The signals from the pouch often trigger the Vagus nerve
to "fire" unique reflex responses.
The Vagus nerve transmits the signal to the brain when we are full.
It seems to "drop off" some info to other stations on the way to the brain.
It is responsible for Diaphragmatic "Dry Heaves" that some experience
in the early days following Bariatric Procedures,
and longer term is often associated with rapid gastric emptying.
(Dumping Syndrome/Dumping)
Many Post-ops claim to have their nose start running
when they take "that last bite" just before feeling too full.
Some experience sneezing or hiccups if they eat a bite too much.
Both are actions inextricably bound to Vagus nerve signals.
Many claim to get a "runny nose" with one bite too much food for their pouch,
and hiccups from eating too fast.
Many Gastric Bypass Post-ops have similar odd signals
associated with the connections that the Vagus nerve makes along it’s wandering path.

This doesn't just happen with WLS patients. For years now, after my very thin husband eats a big meal he starts sneezing. It's embarrassing for him when we go to restaurants! We didn't know what was causing it until I started reading about the vagus nerve during my WLS research phase.
I've had the runny nose and the hiccups signals post-op.
Since I was a kid I've always sneezed at least twice in a row when I was really hungry. Everyone has been telling me for years that I was crazy and that the two things weren't related. Guess I was right all along!
