This condition cannot be prevented. If there is a family history of pyloric stenosis, a new baby should be closely watched for any symptoms.
If treatment is prompt, there are usually no long-term side effects from pyloric stenosis. Recovery depends on the general health of the infant and how quickly a diagnosis and treatment were made.
There are no direct risks of pyloric stenosis to others. This is not a contagious condition, but it can run in families.
