Food passes from the stomach to the small intestine. In pyloric stenosis, food cannot pass freely because the entrance between the stomach and the small intestine narrows. The narrowing is caused by the enlargement of the pylorus (the muscle at the entrance to the stomach). Almost all cases of pyloric stenosis happen in very young babies (usually 3-12 weeks old). This problem happens about 2-4 times out of every 1,000 births. It is much more common in males than in females. The sooner pyloric stenosis is treated, the fewer problems will result and the healthier your baby will be, so if you think your child has this condition, contact your doctor immediately.

Blood-tinged vomit (This happens when repeated vomiting irritates the stomach, causing mild stomach bleeding.)
Your doctor will ask about symptoms your child is experiencing and about his or her medical history. He or she will also perform a physical examination. An olive-shaped knot caused by the presence of pyloric stenosis is often felt by the experienced examiner. If your baby is diagnosed with pyloric stenosis, you and your family will be referred to a pediatric surgeon (a doctor specializing in surgery in children).
Pyloric stenosis is treated with a surgery called a
, with your baby asleep under anesthesia. In a pyloromyotomy, the outside of the pylorus muscle is cut to relieve the blockage. Prior to surgery, fluids and electrolytes will be given intravenously to correct the dehydration and electrolyte imbalances that are common in babies with pyloric stenosis. After the operation, fluids are given by vein until the baby can take all of his or her normal feedings by mouth.
There are no known ways of preventing pyloric stenosis, although it is possible that breastfeeding might reduce the risk.
