Diseases and Conditions
Pyloric stenosis is an uncommon condition in infants that blocks food from entering the small intestine.
Normally, a muscular valve (pylorus) between the stomach and small intestine holds food in the stomach until it is ready for the next stage in the digestive process. In pyloric stenosis, the pylorus muscles thicken and become abnormally large, blocking food from reaching the small intestine.
Pyloric stenosis can lead to forceful vomiting, dehydration and weight loss. Babies with pyloric stenosis may seem to be hungry all the time.
Surgery cures pyloric stenosis.
