Doctor Oz was asked by Mary-Anne, a woman in his audience, why she sneezes a few times in a row whenever her stomach is full or when she has a large meal.
Dr. Oz said that some people (very few) have a stomach sneeze reflex. Your stomach has auto pilot nerves that tell your brain when it is close to full, and these nerves are very close to your sneeze nerves. In only 2 families have scientists seen where these nerves cross on so people sneeze when they are full. Very interesting!
