Pyloric Stenosis: Understanding This Rare Condition

  • June 13, 2023
  •  by Alissa McMillan

Having a sick child is one of the scariest things a parent can face. A condition like pyloric stenosis can be especially scary since it makes it difficult for a child to keep their food down. Fortunately, it’s a rare condition. However, knowing the symptoms will help your child get the treatment they need as quickly as possible.

Pyloric stenosis affects the pyloric muscle that separates the stomach from the small intestine. It causes the muscle to thicken and swell, preventing the natural digestion process. This can result in projectile vomiting, dehydration, and constipation. The condition is treated surgically allowing babies to eat again within 24 hours.

What is Pyloric Stenosis?

Pyloric stenosis is a rare gastric outlet obstruction that affects around three out of every 1,000 babies in the United States. While it may not affect many infants, it has a major impact on those who develop the condition. This is because it affects the pyloric muscle, an important valve that allows people to digest food properly.

The pyloric muscle is located between the stomach and the first part of the small intestine. When healthy, it acts as a valve that holds food in the stomach until it’s ready for the next part of the digestive process. Unfortunately, this muscle can thicken and become enlarged. This prevents food from reaching the small intestine, leading to serious symptoms and complications. 

Symptoms

Symptoms of pyloric stenosis usually develop within three to five weeks after birth. Babies with pyloric stenosis develop symptoms such as:

  • Increasingly severe projectile vomiting
  • Constant hunger
  • Stomach contractions
  • Weight loss
  • Constipation
  • Dehydration

Babies can’t tell you that they’re thirsty, but there are signs of dehydration that you can be on the lookout for. Lethargy is a common sign as well as crying without tears. You may also notice fewer wet diapers or diapers that aren’t as wet as they usually are. 

Risk Factors

The root cause of pyloric stenosis isn’t currently known. However, there are certain risk factors that may play a role in developing the condition.

They include: 

  • Being firstborn, especially boys
  • Being white or Hispanic
  • A family history of the condition
  • Premature birth
  • Smoking while pregnant
  • Certain antibiotics

Certain antibiotics can be a risk factor in a couple of different ways. In some cases, it may be due to a baby receiving medication only a few weeks after being born. Pyloric stenosis can also occur if the mother took antibiotics late during the pregnancy.

Learn when pediatric surgery may be necessary for your child.

Diagnosis

Your child’s pediatrician can diagnose pyloric stenosis. This can be done using:

  • Blood tests
  • Abdominal ultrasound
  • X-rays

Blood tests can be used to check your baby for dehydration or an electrolyte imbalance. With an abdominal ultrasound, the pediatrician can see and confirm if pyloric stenosis is present. Sometimes the ultrasound results may not be clear enough to provide a conclusive result. In cases like these, X-rays of the digestive system can be taken to detect the condition.

Treatment

Surgery is the only treatment for pyloric stenosis with procedures often performed on the same day. It may be necessary to stabilize your child first if they are dehydrated or have an electrolyte imbalance. In these instances, your baby will be provided fluids using an IV beforehand. They will go to surgery once tests indicate that they have been adequately rehydrated and stabilized.

Surgery for pyloric stenosis is known as a pyloromyotomy. The surgeon cuts the outer layer of the pylorus muscle. This allows the muscle to bulge out and makes it easier for food from the stomach to the small intestine.

More fluids may be required once surgery has been completed. You should be able to resume feeding your child small amounts of breast milk or breast milk formula within 24 hours of following surgery. They will start gaining weight as they are able to keep food down. Surgery has a 97.8% success rate and there shouldn’t be any long-term effects for your child from the procedure.
