This article will discuss what sphincter of Oddi dysfunction (SOD) is, along with its symptoms and causes. It also covers diet and treatment.

SOD occurs when the sphincter of Oddi does not open and close properly. This can happen for many reasons, including:
- anatomical abnormalities
SOD creates a buildup of digestive juices in the pancreas and liver, which leads to intense abdominal pain.
