Patient's question:
NoDoctor's answer:
For infants who vomit a small amount of milk shortly after being fed, generally in good condition, with normal appetite, without crying after vomiting, and without any other symptoms or signs, commonly referred to as "spit-up," it is a normal phenomenon. Vomiting, occurring several times a day, gradually becoming more frequent and developing into projectile vomiting, with severe vomiting occurring about half an hour after each meal, sometimes with vomit volume exceeding intake volume, and vomit without bile, while appetite remains normal, and gradual weight loss due to prolonged vomiting, may indicate congenital hypertrophic pyloric stenosis. Please differentiate.
