Question
Why would a three-month-old baby experience severe vomiting?
Answer
Newborn vomiting can be caused by either physiological factors or pathological conditions. Physiological vomiting is usually related to the immature structure and function of the stomach, which tends to improve as the baby grows. Pathological vomiting, on the other hand, may be due to gastrointestinal infections, overeating, digestive system malformations, or other internal and external diseases. Depending on the type of vomiting in newborns, it can be categorized into regurgitation, common vomiting, and projectile vomiting. Regurgitation is common in infants under six months old and usually does not require concern; common vomiting is often preceded by nausea and continuous or repeated vomiting may suggest gastrointestinal issues; while projectile vomiting could be a sign of pyloric stenosis or other serious conditions. Additionally, vomiting may be accompanied by other symptoms such as abdominal swelling, bulging fontanelle, or abnormal physical signs, all of which could be manifestations of different diseases. Understanding these symptoms can help in further diagnosis and treatment.
