Risk Factors for GERD in Infants

Primary Risk Factors

The American Academy of Pediatrics notes that parental GERD represents a documented genetic predisposition, with new epidemiologic and genetic evidence confirming heritability of GERD, erosive esophagitis, Barrett esophagus, and esophageal adenocarcinoma 1, 2, 3
The presence of GERD in both parents substantially increases an infant's risk compared to the general population 1
Maternal asthma creates a bidirectional risk relationship with GERD, as population trends show global epidemics of both obesity and asthma contribute to increased GERD prevalence 1, 2, 3

Exclusive breastfeeding is actually protective against GERD in infancy, with reported lower rates of GERD in breast-fed infants compared to formula-fed infants 4

At 10 months of age, an infant is past the peak incidence of physiologic reflux, which occurs at 4 months (affecting ~50% of infants) and declines to only 5-10% by 12 months 1, 2

The American Academy of Pediatrics recommends that warning signs requiring immediate evaluation include: bilious vomiting, gastrointestinal bleeding, consistently forceful vomiting, fever, abdominal tenderness or distension 6, 5
Troublesome symptoms suggesting GERD rather than benign reflux include: feeding refusal, recurrent vomiting, poor weight gain, irritability, sleep disturbance, dysphagia, or arching during feedings 1, 2, 4
