Older children
In children with heartburn or regurgitation without red flag symptoms, a trial of lifestyle changes and dietary education may be initiated. If a child is overweight, it is important to inform the patient and parents that excess body weight is associated with GERD. The head of the bed can be elevated along with left lateral positioning. The guidelines do not support any probiotics or herbal medicines.
If bothersome symptoms persist, a trial of acid-suppressing medication for 4-8 weeks is reasonable. A PPI is preferred to a histamine-2 receptor blocker. PPI safety studies are lacking, but case studies suggest an increase in infections in children taking acid-suppressing medications. Therefore, as with infants, if medications are used they should be prescribed at the lowest dose and for the shortest period of time possible. If medications are not helping, or need to be used long term, referral to a pediatric gastroenterologist can be considered. Of note, the guidelines do support a 4-8 week trial of PPIs in older children as a diagnostic test; this differs from the recommendations for infants, in whom a trial for diagnostic purposes is discouraged.
Diagnostic testing
Refer to a gastroenterologist for endoscopy in cases of persistent symptoms despite PPI use or failure to wean off medication. If there are no erosions, pH monitoring with pH-impedance monitoring or pH-metry can help distinguish between nonerosive reflux disease (NERD), reflux hypersensitivity, and functional heartburn. If it is performed when a child is off of PPIs, endoscopy can also diagnose PPI-responsive eosinophilic esophagitis. Barium contrast, abdominal ultrasonography, and manometry may be considered during the course of a search for an alternative diagnosis, but they should not be used to diagnose or confirm GERD.
The bottom line
Most GER is physiologic and does not need treatment. First-line treatment for GERD in infants and children is nonpharmacologic intervention.
