Newborn vomits yellow milk

Some newborns will spit out milk when drinking milk. Some babies will spit out white milk, while others will spit out yellow milk. This may be caused by gastrointestinal problems in the newborn. Parents should first check the baby's body to see if there is any gastrointestinal problem, and then carry out targeted treatment. So why do newborns sometimes spit out yellow 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.
