The baby often vomits after eating milk. Why is this?
In some babies, frequent spray vomiting may be caused by hypertrophic pylorus (HPS), and one of the 500 babies will occur HPS.
What is HPS?
HPS is the narrow of the pyloric door, that is, the muscle valve at the bottom of the stomach. When it becomes hypertrophic, breast milk or formula milk cannot enter the small intestine, which causes excessive jet vomiting, usually 2-6 weeks after birth.

Babies may have signs of HPS
Vomiting: Vomiting after each feeding or after several feeding, manifested as no bile spitting vomiting.This is because breast milk or formula milk is prevented from passing through the stomach with hypertrophic pyloric sphincles. As the pyloric muscles thicken, vomiting may gradually deteriorate.
患 has always been hungry: babies with HPS will feel hungry again after vomiting.They always seem hungry.
Abdominal tightening: After feeding, you may see the baby’s upper abdomen with a left -right gastric movement wave.
门 Constipation: Because the narrow pylorus will prevent the baby from eating the intestines, they may be constipated.
减 Dehydration and weight loss: Babies with narrow pyloric doors cannot obtain sufficient liquid and nutrition from feeding, and may occur with malnutrition and dehydration.
How to diagnose HPS?
右 右 ➤ ➤: Deep pressure on the upper abdomen of the right can be 扪 扪 扪, hard texture, active olive -like lump, 2 to 3cm in size.
腹 Ultrasonic examination: Abdominal B -ultrasound examination of the diameter of the pylorus muscle layer is> 1.4cm, wall thickness> 4mm, and the length of the pylorida is> 1.6cm.
钡 ➤ 查 查 查 ➤ ➤ ➤ ➤ ➤ ➤ ➤ ➤ ➤ ➤ ➤ ➤ ➤ ➤ ➤ ➤ ➤ ➤ ➤ ➤ ➤ ➤ ➤ ➤ ➤ ➤ ➤ ➤ ➤ ➤ ➤ ➤ ➤ ➤ ➤, typical “line sample”.
HPS treatment
先 Early treatment: First correct dehydration and electrolyte disorders of children.
硫 Drug therapy: Antoin is the only drug that can be used to treat the narrow pylorus.However, due to its high failure rate and extended hospitalization time, it is not widely used, and it is recommended to use it only when surgery is too dangerous to infants.
Decisive therapy: The pylorus muscle is cut, and the pyloric muscles are cut to the lower layer of the mucosa and the neighboring inner oblique muscles to retain the complete mucosa.Children on the day of surgery can usually be fed normally.
Which babies are more likely to suffer from HPS?
The cause of HPS is unclear, but researchers have pointed out possible risk factors.
在 Gender: The incidence of HPS in boys is four times that of girls.
Race race: White people are more likely to occur HPS than other races.
The History of the Family: The risk of brothers and sisters with HPS children is 30 times that of ordinary people.
素 Early antibiotics: Give some antibiotics (such as erythromycin used to treat pertussis) in the first few weeks after birth, the risk of HPS will increase.In addition, babies born to mothers who take certain antibiotics in the later stages of pregnancy may increase the risk of this disease.
:Smoking during pregnancy: The risk of mothers smoking babies has almost doubled HPS.
大 H hernia: Although most babies with HPS are healthy in other aspects, HPS is more common in babies with inguinal hernia at birth.
：Base feeding: Some studies have shown that bottle feeding will increase the risk of gangster narrowing.But it is unclear whether the increase in risk is related to the feeding of formula milk or bottle itself.
