Pyloric Sphincter Injury

The pyloric sphincter is a crucial muscle located at the end of the stomach, where it meets the small intestine. This muscle controls the flow of partially digested food (chyme) from the stomach into the small intestine. An injury to this sphincter can cause various problems and discomfort. This article provides a detailed overview of pyloric sphincter injury, including its types, causes, symptoms, diagnostic tests, treatments, and more.

A pyloric sphincter injury occurs when this muscle is damaged or impaired. This can disrupt the normal digestive process, leading to a range of symptoms and health issues.
