Spitting Up in Infants
Spitting Up in Infants Facts
Spitting up is the mild vomiting or regurgitation of food, milk, and saliva that can occur in infants. Spitting up is not forceful and does not contain large amounts of food and fluids.
Spitting Up in Infants Causes
A valve between the esophagus and the stomach helps prevent food from coming back up and out of the stomach. In infants, this valve is not well developed and can more easily allow food to go back up the feeding tube and cause spitting up. Because the infant's stomach is small, feeding too much or swallowing too much air can help push food past the valve. As the infant grows and the valve develops, food is less likely to pass this valve and travel up the esophagus. Also, as the infant begins to take solid foods, the spitting up usually decreases.
