Pediatric gastroesophageal reflux disease (GERD) occurs when stomach acid repeatedly flows back into a child’s esophagus, potentially causing symptoms such as feeding difficulties, irritability, coughing, or throat irritation.
What Causes Pediatric GERD?
GERD occurs when a valve at the lower end of the esophagus doesn’t work properly. Normally, this muscle closes to keep acid in the stomach and out of the esophagus. During the first year, infants frequently spit up. This is called laryngopharyngeal reflux (LPR), when stomach acid travels up the esophagus and spills into the throat or voice box. However, in most infants, it’s a normal occurrence caused by the immaturity of both the upper and lower esophageal valves, the shorter distance from the stomach to the throat, and the greater amount of time infants spend lying on their backs.
But repeated exposure to acidic stomach contents may cause long-term airway problems, such as a narrowing of the area below the vocal cords, hoarseness, and possibly eustachian tube dysfunction with ear or sinus infections and hearing loss. Infants who have breathing-related symptoms or feeding problems should be seen by an ENT (ear, nose, and throat) specialist, or otolaryngologist.
