Reflux, often referred to as gastroesophageal reflux (GER) in infants, is a condition where the stomach contents flow back into the esophagus. This is due to the lower esophageal sphincter being underdeveloped or relaxed more than normal. Reflux is common in infants and typically manifests as spitting up or vomiting after feeding. While it can be messy and concerning for parents, reflux is usually normal in healthy infants and tends to improve as the baby grows and the digestive system matures, typically resolving by the age of 12 to 18 months.

However, if symptoms persist, are severe, or are accompanied by weight loss, feeding difficulties, or irritability, it might indicate a more severe form of reflux known as gastroesophageal reflux disease (GERD), which requires medical evaluation and treatment. Parents and caregivers are advised to consult a pediatrician if they have concerns about their baby’s reflux.
