Sphincter of Oddi Dysfunction
Sphincter of Oddi Dysfunction (SOD) is a condition where a round muscle that controls the flow of two digestive juices, bile and pancreatic juice, does not open properly. The backup of digestive juices can result in severe abdominal pain.

What is Sphincter of Oddi Dysfunction?
The liver makes a chemical called bile, and the pancreas produces pancreatic juice. These important chemicals are part of the digestive process. They flow from the liver and pancreas into the small intestine. The sphincter of Oddi controls the flow of these chemicals.
A sphincter is a muscle that can open and close and is usually round. In sphincter of Oddi dysfunction, the sphincter muscle does not open when it should. This causes a backup of digestive juices and can cause severe abdominal pain. Also the sphincter of Oddi prevents the contents of the bowel from backing up into the pancreas and the liver’s bile ducts.
There are two main types of sphincter of Oddi dysfunction:
- If the bile from the liver’s bile ducts backs up, it is called biliary dysfunction.
- If the backup happens in the pancreas, it is called pancreatitis. This is an inflammation of the pancreas.
Sphincter of Oddi dysfunction symptoms include:
- Abdominal pain
- Loss of appetite
- Fever and chills
SOD risk factors are similar to those for gallstones, including:
- Gender: the condition is more common in women than men
- Age: being age 60 or older
- Overweight and obesity
- Eating too many fats and cholesterol and not enough dietary fiber
- High cholesterol
- Losing weight quickly
