Ear injuries can occur when air pressure outside the ear increases or
decreases while the air pressure inside the ear remains the same. This might
happen when an airplane changes altitude or when a scuba diver descends or
ascends under water.
A gradual increase in air pressure outside the
ear can cause a buildup of fluid in the space behind the eardrum (otitis media with effusion).
A sudden, dramatic increase in air pressure outside the ear can
eardrum to rupture.
Both of these types of injuries are know as barotrauma.
Spitting up, also known as reflux or gastroesophageal reflux disease (GERD), is messy. But unlike vomiting, it usually isn't painful, and babies often don't notice they're spitting up. Most babies outgrow this by 9 or 10 months of age.
