Gastroesophageal reflux (GER) occurs when stomach contents flow back into the esophagus, causing discomfort and spitting up. It is common in infants due to an immature lower esophageal sphincter. Most cases resolve on their own by the time the child is one year old. Treatment may involve feeding changes, such as smaller, more frequent meals, and keeping the infant upright after feeding. In severe cases, medication or surgery may be necessary.
