Pyloric stenosis is a narrowing of the pylorus. The pylorus lies between the stomach and the small intestine, and when it thickens, it prevents food from passing out of the baby’s stomach and into the small intestine. It affects small babies, and the symptoms usually develop about three to five weeks or so after the birth. The cause of the thickening of this valve is not apparent. If you suspect this condition, you need to see a doctor because it will not get better on its own. Once the doctor decides pyloric stenosis is the right diagnosis, your child will need surgery. The surgery is minimally invasive, and your baby will typically recover quite quickly.
Vomiting is one of the first symptoms. At first, this may be mild, but as the problem gets worse, it causes projectile vomiting. Breast milk or formula comes forcefully out of the mouth like a fountain. It may smell curdled because it has already mixed with some stomach acid. Most babies have some reflux after feeding which involves spitting up. If their stools are normal and they don’t have projectile vomiting, you should not suspect pyloric stenosis. Ongoing vomiting can cause an electrolyte imbalance in the body. The doctor may order blood tests to check your baby’s electrolyte levels. He will address the issue of there is an imbalance.
