Major Symptoms Of Pyloric Stenosis

Pyloric stenosis is a rare condition where the valve between the small intestine and the stomach blocks food from passing from the stomach into the small intestine. This valve is called the pylorus, and it is supposed to be closed as the stomach prepares the food to enter the small intestine. It then opens to allow the food to pass and undergo the next stage of digestion. If an individual has pyloric stenosis, the valve is thick and enlarged and can’t open the way it should. Doctors don’t know what causes pyloric stenosis, but it is more common in boys, especially firstborn boys, in babies who have Northern European ancestry, and in premature infants.
