Gastrointestinal issues are the main symptoms of pyloric stenosis. Most babies with this condition appear fine at birth.

As the pylorus valve thickens over time, the vomiting becomes more frequent and explosive. It may be projectile vomit, meaning that it travels several feet from the baby’s mouth. 2 Dehydration. The thickened pylorus not only blocks the passage of solid food, but also that of liquids. A baby who is dehydrated may cry without tears, have fewer wet diapers, and become listless. 3 Hunger. A baby with pyloric stenosis may want to constantly feed or be fussy because of hunger. 4 Constipation. Without adequate food and liquid reaching the intestines, the condition can cause constipation. 5 Stomach cramps. Some parents notice “wave-like” contractions that move across their baby’s abdomen after a feeding. This occurs as the stomach muscles strain to try to move the food through the narrowed pylorus lumen and pyloric sphincter.

Function
- The pylorus is a muscular valve located between the stomach and the small intestine. Its the exit point of the stomach and the gateway to the duodenum of the small intestine. It helps the stomach hold food, liquids, acids, and other matter until they are ready to move on to the small intestine and be further digested and then absorbed.

- Pyloric stenosis is most likely to affect young babies. Its found in 2 to 3 out of every 1,000 babies. It most often appears in the first 2 to 8 weeks of life, although it can occur in babies up to 6 months of age. The condition interferes with feedings, so it can affect growth and hydration. Thats why early diagnosis and treatment are important.
Symptoms
- Gastrointestinal issues are the main symptoms of pyloric stenosis. Most babies with this condition appear fine at birth. Symptoms typically begin and become progressively worse during the first few months of life. Symptoms may include: Unlike with a stomach bug, babies with pyloric stenosis generally dont seem as sick in between feedings.

- When pyloric stenosis is suspected, your babys doctor will take a thorough history and perform a physical exam of your childs abdomen. If the doctor can feel a thickened pylorus muscle, which may feel like an olive, no further tests may be needed. If the doctor cannot feel the pylorus, they may order an abdominal ultrasound to examine the abdominal tissue in order to see the pylorus…
Treatment
- Pyloric stenosis needs to be treated. It wont improve on its own. Your child will need surgery called pyloromyotomy. During this surgery, which can be done laparoscopically, a surgeon will cut through part of the thickened muscle in order to restore a pathway for food and liquid to pass through.
