What is the reason why newborn babies always spit up milk?

Spitting up in newborns is a very common condition, but it is not normal for newborns to spit up milk all the time. Generally speaking, severe spitting up in newborns has both physiological and pathological reasons. In addition, external reasons such as improper feeding and care can also cause newborns to spit up frequently. Vomiting caused by different reasons requires different methods to alleviate. Below we will introduce in detail the reasons why newborns frequently spit up milk!

There are both physiological and pathological reasons for severe spitting up in newborns. The baby's stomach capacity is small and the esophageal muscle tension is low, so food is easy to spit out. It may also be caused by colds, constipation, etc. Incorrect feeding posture, feeding too quickly, adding complementary foods too early, etc. are also the causes of severe spitting up in newborns.

1. Physiological reasons

Your baby's stomach doesn't hang down like it does in older children and adults, but is in a horizontal position. This will reduce the stomach's capacity and allow it to store less food. In addition, because the baby's esophageal muscle tension is relatively low, the cardia is relatively loose and not tightly closed, so it is easy for food to break out of the cardia and cause vomiting.

These physiological vomiting will stop as the baby grows older as the neural regulation of gastric ptosis, intestinal motility, and endocrine secretion of gastric acid and proteolytic enzymes gradually strengthen.

2. Pathological causes

Colds, bacterial infections, constipation, pyloric stenosis, esophageal atresia, intestinal atresia, intestinal malrotation, congenital megacolon, etc. can all cause abnormal spitting up in babies.

3. Improper feeding and care

Improper feeding posture, feeding too quickly, too much milk or too short an interval between meals; turning the baby too much during feeding; adding complementary foods too early; when feeding with a bottle, the hole of the nipple is too large, causing the milk to flow out too quickly and not have time to swallow, etc. These improper feeding methods will cause the baby to spit up milk.

When the baby is 6 months old, he or she will not only master the sucking skills well, but also have a more mature gastrointestinal function, and the number of spitting up will be significantly reduced. If a newborn baby often spits up milk, mothers must distinguish whether it is due to physiological reasons, pathological reasons or improper feeding, so as to decide how to solve the problem of baby spitting up milk. Parents don’t need to worry about spitting up under normal circumstances, as long as the baby’s weight gain is normal and his mental state is good.
