Diseases and Conditions
Infant reflux occurs when food backs up (refluxes) from a baby's stomach, causing the baby to spit up. Sometimes called gastroesophageal reflux (GER), the condition is rarely serious and becomes less common as a baby gets older. It's unusual for infant reflux to continue after age 18 months.
Reflux occurs in healthy infants multiple times a day. As long as your baby is healthy, content and growing well, the reflux is not a cause for concern.
Rarely, infant reflux can be a sign of a medical problem, such as an allergy, a blockage in the digestive system or gastroesophageal reflux disease (GERD).
