Pyloric stenosis is narrowing of the opening from the stomach to the duodenum, the first part of the small intestine. Narrowing prevents food from passing freely between the 2 structures. Pyloric stenosis affects your baby's ability to get adequate nutrition and hydration. The sooner your baby is treated, the better the outcomes.
Pyloric stenosis is rarely present at birth. Symptoms generally appear when babies are 3-12 weeks old. The most common symptom is forceful, projectile vomiting. This is because of the build up of formula or milk in the stomach that cannot pass into the small intestine.
Pyloric stenosis may also cause:
Your baby to act hungry most of the time
dehydration, such as less urination, dry mouth, and crying without tears
Fewer bowel movements
Blood-tinged vomit —occurs when repeated vomiting irritates the stomach, causing mild stomach bleeding
If your baby is diagnosed with pyloric stenosis, they will be referred to a pediatric surgeon for treatment.
Pyloric stenosis is treated with pyloroplasty (also called a pyloromyotomy), a procedure to relieve blockage.
Prior to surgery, fluids and electrolytes will be given by IV to correct any dehydration or electrolyte imbalances that are common in babies with pyloric stenosis. After the procedure, IV fluids are given until your baby can take all of their normal feedings by mouth.
