Patient's question:
My son is almost fourteen months old. A few days ago, he had a fever and received saline drips for several days at the hospital. He's just started to feel a bit better, but today, for some reason, he started vomiting everything he ate after drinking formula in the morning. Now, whenever he eats porridge or drinks formula, he vomits every time. Why is this happening?Doctor's answer:
Spit-up is a common phenomenon in infants, caused by two main reasons: first, it is a symptom of systemic or gastrointestinal diseases; second, the anatomical and physiological characteristics of the infant's gastrointestinal tract make it prone to spit-up. Overall, spit-up caused by the second reason is more common. The milk ingested through the mouth first passes through a tube called the esophagus before entering the stomach. The stomach has two gates: one connects to the esophagus and is called the cardiac sphincter, which is the stomach's entrance, and the other connects to the intestines and is called the pylorus, which is the stomach's exit.
