Newborns often vomit milk, although some babies vomit slightly while others vomit more severely, especially in severe cases that make parents more worried. So what happens when a newborn baby spits milk?
There are several reasons why newborns may vomit milk:
1. Physiological reasons. A baby's stomach is not vertical like larger children and adults, but rather in a horizontal position. This will make the stomach smaller and store less food. Moreover, the tension of the esophageal muscles in infants is relatively low, and the cardia is relatively relaxed and not tightly closed, making it easy for food to break through and cause vomiting. This physiological vomiting of milk, as the baby grows older, the neural regulation function of gastric ptosis and intestinal peristalsis becomes stronger, as well as the endocrine function of gastric acid and proteolytic enzymes will gradually increase, and the baby will no longer vomit milk.
2. Pathological reasons. Cold, bacterial infection, constipation, pyloric stenosis, esophageal obstruction, intestinal obstruction, malrotation of the intestine, congenital megacolon, etc. can all cause infants to vomit milk. In this case, it is necessary to go to the hospital for examination in a timely manner and then receive targeted treatment.
3. Improper feeding and care. Improper feeding posture, feeding too quickly, excessive milk, or short intervals between meals, excessive flipping of the baby during feeding, premature addition of complementary foods, and feeding with a bottle with a nipple opening that is too large, can all cause the milk to flow out too quickly and not be swallowed in time.
Newborns often vomit milk, and parents must distinguish whether this is physiological, pathological, or improper feeding in order to decide how to solve the problem of infant vomiting. Under normal circumstances, parents do not need to worry about spitting out milk. Only when the baby's weight gain is normal, their mental state is good, and there are no other discomfort symptoms, will the symptoms of spitting out milk gradually disappear as the baby grows older.
