What is a concerning outcome for an infant diagnosed with gastroesophageal reflux?

When evaluating an infant diagnosed with gastroesophageal reflux, difficulty feeding is indeed a concerning outcome. Infants with gastroesophageal reflux may experience pain or discomfort during feeding due to the backflow of stomach contents into the esophagus. This can lead to an aversion to feeding, resulting in insufficient caloric intake and potential malnutrition. Additionally, if feeding is met with distress or if the infant consistently refuses to eat, it can affect overall growth and development.

In contrast, good weight gain often indicates that the infant is able to manage feeding well, despite reflux symptoms. Excessive spit-up can be a common occurrence in infants with this condition, but it doesn't always correlate with distress or poor feeding; many infants can spit up without any significant issues. Regular bowel movements provide insight into digestive health but are not directly related to concerns about the reflux itself. Therefore, difficulty feeding stands out as a key issue requiring further assessment and possible intervention.
