What are the Causes of Pediatric Pyloric Stenosis?
The exact cause of pediatric pyloric stenosis is not known.
Though the exact cause of pediatric pyloric stenosis is not known, it is believed to be multifactorial, with both, hereditary and environmental factors contributing to the condition. Pediatric pyloric stenosis is known to run in families, often affecting the first male child.
Babies who develop pyloric stenosis are not born with it, but the thickening of the pylorus occurs progressively after birth.
It is not known exactly what causes the thickening of the muscles of the pylorus.
There are many PS cases that don't fit these "rules": girl babies and later children also get the condition. There are other general characteristics of PS that also have many exceptions: it affects more Caucasians, children with blood groups A and O, children of mothers who were stressed during the last months of pregnancy.
If your baby is not keeping food down, vomits increasingly and powerfully, is losing weight and/or condition, is not passing motions and urine, suspect PS, get your baby tested, don't be put off by an unsuspecting and ill-informed doctor. On the internet there are many stories of children being treated only just before it's too late.
