My infant has gerd, what is the chance that they have a hiatal hernia?

Very Low: Although not impossible, an infant that is growing, developing well, and meeting milestones is highly unlikely to have a major GI problem, even with reflux. In fact most babies do have some degree of reflux, and rarely does medicine help with this - although it can help with the discomfort associated with reflux.

Unlikely: Though many children may have symptoms of reflux with episodes of vomiting, it usually is only of concern if there is associated respiratory problems or poor weight gain. The symptoms are monitored to see if they improve once advancement of diet to more solid food occurs. If significant symptoms, including respiratory complaints, evaluation would include a contrast study to exclude hiatal hernia.
