If you have a newborn, it’s common to see them spit up occasionally. However, if your baby experiences consistent and forceful vomiting, it may indicate a more serious issue known as pyloric stenosis. Fortunately, this condition is treatable and can help restore your baby’s digestive health.

What is Pyloric Stenosis?

Pyloric stenosis is a condition characterized by the narrowing of the pylorus, the muscle valve located at the stomach’s exit. This narrowing obstructs the passage of breast milk or formula into the small intestine, resulting in severe or projectile vomiting. Pyloric stenosis affects approximately 3 out of every 1,000 infants in the U.S. and is the most prevalent reason for surgery in the first few months of life.

Symptoms of Pyloric Stenosis

Parents should be vigilant for signs of pyloric stenosis. Symptoms may include:

  • Frequent and forceful vomiting
  • Persistent hunger after feeding
  • Dehydration, which can manifest as dry mouth or decreased urination
  • Weight loss or failure to gain weight

Early diagnosis is crucial as it can lead to dehydration and malnourishment. If you notice these symptoms, seek medical attention promptly.

What Causes Pyloric Stenosis?

The exact cause of pyloric stenosis remains unknown, but it is believed to involve genetic and environmental factors. It tends to occur more frequently in males and is often seen in families with a history of the condition.

Diagnosing Pyloric Stenosis

Diagnosis typically involves a physical examination, where the doctor may feel for an enlarged pylorus. Imaging tests such as an ultrasound can also confirm the diagnosis.

Treatments for Pyloric Stenosis

The primary treatment for pyloric stenosis is surgery, known as pyloromyotomy. This procedure involves widening the pylorus to allow food to pass through. Most infants recover quickly and return to normal feeding and growth.

Prognosis for Pyloric Stenosis

With timely intervention, the prognosis for infants with pyloric stenosis is excellent. Most babies thrive and develop normally after treatment.
