Is regurgitation rare in infants?

• A. Yes, regurgitation is rare
• B. No, regurgitation is very common
• C. Sometimes, depending on feeding
• D. It always indicates a problem

Answer: (B)

Regurgitation is a common, normal finding in healthy infants. The lower esophageal sphincter is immature in early life, and many babies feed in a mostly horizontal position, so small amounts of stomach contents can flow back up after feeding. This results in spit-up that is typically effortless, non-bloody, and not distressing to the infant. Most infants outgrow this pattern as the digestive system matures, with many reducing or stopping regurgitation by about 12 to 18 months.

It's important to distinguish regurgitation from vomiting. Regurgitation is usually gentle and doesn’t cause dehydration or weight loss, whereas vomiting is more forceful and may be accompanied by distress or poor intake. Red flags that would prompt medical evaluation include poor weight gain, persistent or forceful vomiting, coughing or wheezing with feeds, blood in the vomit or stool, dehydration, or any signs of illness.

In summary, regurgitation is very common in infancy and often benign, with attention to growth and any warning signs guiding whether further evaluation is needed.
