Initial Management of Gastroesophageal Reflux (GER) in Infants

Understanding GER vs. GERD in Infants

The American Academy of Pediatrics notes that GER is the physiologic passage of gastric contents into the esophagus, occurring in more than two-thirds of otherwise healthy infants 3
GERD is defined as reflux associated with troublesome symptoms or complications that affect quality of life, according to the North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition 1
Proper distinction between GER and GERD is crucial as treatment approaches differ significantly, as stated by the European Society for Pediatric Gastroenterology, Hepatology, and Nutrition 2

For breastfed infants, the American Academy of Pediatrics recommends considering a 2-4 week maternal elimination diet that restricts at least milk and egg 1
For formula-fed infants, the European Society for Pediatric Gastroenterology, Hepatology, and Nutrition suggests considering switching to an extensively hydrolyzed protein or amino acid-based formula 1, 2
The North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition recommends thickening feedings with up to 1 tablespoon of dry rice cereal per 1 oz of formula, which increases caloric density 1, 2
Reducing feeding volume while increasing feeding frequency to minimize gastric distension is advised by the American Academy of Pediatrics 1
Implementing proper burping techniques after feedings is recommended by the European Society for Pediatric Gastroenterology, Hepatology, and Nutrition 1

Keeping the infant in a completely upright position when awake is recommended by the North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition 1, 2
Avoiding prone positioning during sleep due to SIDS risk is advised by the American Academy of Pediatrics 2
Avoiding environmental tobacco smoke exposure is recommended by the European Society for Pediatric Gastroenterology, Hepatology, and Nutrition 1, 2

Closely monitoring weight gain as it is the primary outcome measure is recommended by the North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition 1
If no improvement is seen after 2 weeks of feeding changes, evaluating for other causes of symptoms and considering referral to pediatric gastroenterology is advised by the American Academy of Pediatrics 1

Upper endoscopy with esophageal biopsy is indicated in infants with poor weight gain who fail to respond to initial management, according to the North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition 1
Warning signs requiring immediate evaluation include bilious vomiting, gastrointestinal bleeding, consistently forceful vomiting, fever, and abdominal tenderness or distension, as stated by the European Society for Pediatric Gastroenterology, Hepatology, and Nutrition 1

Pharmacologic therapy should be reserved for infants who fail to respond to conservative measures, as recommended by the American Academy of Pediatrics 1, 2
Overdiagnosis and overtreatment with acid suppressants before trying conservative measures should be avoided, according to the North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition 1, 2

Failing to recognize the increased caloric density when thickening feeds, which can lead to excessive weight gain, is a common pitfall to avoid, as noted by the European Society for Pediatric Gastroenterology, Hepatology, and Nutrition 1
Relying solely on symptoms for diagnosis, which can be difficult in infants, should be avoided, according to the American Academy of Pediatrics 1
Using proton pump inhibitors for physiologic GER rather than only for confirmed GERD is not recommended, as stated by the North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition 2
