Pyloric stenosis

Pyloric stenosis is a condition in which a baby's pylorus (the muscle between the stomach and the first part of the small intestine) gradually swells and thickens, which interferes with food entering the intestine. This causes the baby to vomit most or all of their feedings.

Vomiting caused by pyloric stenosis usually starts gradually and gets worse over time. As the pylorus becomes tighter, the baby vomits more frequently and more forcefully (projectile vomiting). As vomiting continues, the baby will lose weight and become dehydrated.

Pyloric stenosis can occur any time between birth and 5 months of age, but it most commonly develops about 3 weeks after birth. The start of symptoms may be delayed if the baby was premature.

Pyloric stenosis is corrected with surgery (pyloromyotomy).

Due to the threat of the COVID-19 (Coronavirus), we are taking precautionary measures to protect our staff and patients. We are implementing a temporary NO VISITOR policy at this time. Only patients or patients and their guardians will be allowed into the office. Please note, this is not to inconvenience anyone! The virus is a very real threat and it is essential that we stay healthy in order to provide needed care for our patients. If you are sick, we ask that you CALL the office to speak with a nurse before you come in. The nurse will provide specific instructions for you. Please DO NOT enter the office if you are sick (upper respiratory symptoms, fever, cough, or flu like symptoms). We are closely monitoring the situation and will update you as circumstances change. Thank you for your understanding!!
