Some infants spit up or throw up so frequently that they are said to have gastroesophageal reflux .
This term describes splashing or pushing of stomach contents backwards up into the esophagus, and sometimes, out the mouth. All of us have some reflux every day. Most of the time, reflux causes no problems or discomfort, and often, we are not even aware when it happens. When a baby throws up after nearly every feeding and numerous times between feedings, parents often become concerned and they seek medical advice. They may be worried that there is something seriously wrong with their baby's stomach or intestinal tract.
