The pyloric sphincter is a ring-like muscle located at the end of the stomach where it meets the small intestine. Its primary job is to control the flow of partially digested food from the stomach into the small intestine. Pyloric sphincter atrophy occurs when this muscle weakens or shrinks, impairing its function and potentially leading to various digestive issues.
Types of Pyloric Sphincter Atrophy
- Congenital Atrophy: Present from birth due to genetic factors.
- Acquired Atrophy: Develops over time due to other health conditions or factors.
- Functional Atrophy: Results from the muscle not working properly despite no visible shrinkage.
- Localized Atrophy: Affects only a part of the pyloric sphincter.
- Diffuse Atrophy: Affects the entire pyloric sphincter muscle.
- Secondary Atrophy: Caused by another underlying disease or condition.
- Ischemic Atrophy: Due to reduced blood flow to the muscle.
- Inflammatory Atrophy: Resulting from inflammation affecting the muscle tissue.
- Degenerative Atrophy: Associated with progressive muscle degeneration.
- Post-surgical Atrophy: Resulting from surgical interventions that impact the muscle.
