Your baby can't empty the formula that is in the stomach into the bowel, because pyloric stenosis is the abnormal narrowing of the pyloric sphincter which prevents passage of food to the duodenum of the small intestine.
“your baby can’t empty the formula that is in the stomach into the bowel”-pyloric stenosis is an anomaly of the upper gastrointestinal tract. the condition involves a thickening, or hypertrophy, of the pyloric sphincter located at the distal end of the stomach. this causes a mechanical intestinal obstruction, which leads to vomiting after feeding the infant. the vomiting associated with pyloric stenosis is described as being projectile in nature. this is due to the increasing amounts of formula the infant begins to consume coupled with the increasing thickening of the pyloric sphincter.
