The Sphincter of Oddi is a central gate to many liver, gallbladder and pancreas problems. Many scientists believe that the Sphincter of Oddi Dysfunction (SOD) is a culprit of the pancreas diseases and it is the common source of chronic pain after gallbladder removal.
Around the common bile duct, pancreatic duct and the duodenum wall there is a muscle valve called the Sphincter of Oddi. The Sphincter of Oddi, named after Ruggero Oddi, an Italian anatomist who discovered this structure in 1887. The Sphincter of Oddi controls moving of the bile from the liver, and gallbladder and pancreatic juice from the pancreas into the duodenum.
Normally, when semi digestive food moves from the stomach into the duodenum sphincter of Oddi opens. Large amount of the gallbladder bile and alkaline pancreatic juice is released to digest this food. When no food in the duodenum, sphincter of Oddi is closed so the bile from the liver is collected in the gallbladder.
Regulation of this complicated work is under control of nervous system and special blood messengers – digestive hormones. Stress, fasting, “harsh” liver cleansing, gallbladder removal, bad eating habits, alcohol, some medications, and recreation drugs badly influence in proper regulation and work of the sphincter of Oddi.
Spasm or blockage of this muscle valve may cause pancreatic juice goes backward, thereby increasing the pressure inside the pancreatic duct. Digestive enzymes shut inside the pancreas, begin to digest their own pancreas, initiate inflammation, pain, and finally the death of pancreatic tissue. Thus, chronic pancreatitis is developed.
Tumor, gallbladder stone, or scaring can make an anatomical blockage of the sphincter of Oddi. It happens relatively rare. However, more often can be functional, temporal spasms of the sphincter of Oddi without any abnormality in the tests. The common reason for sphincter to be spasmodic is irritation of it by the “aggressive” bile and pancreatic juice.
What could make bile and pancreatic juice “aggressive”, corroded, and irritated? Let’s explain that.
The liver’s most important functions are producing and releasing bile and removing the toxins from our body by dividing them into water-soluble and fat-soluble wastes.
Water-soluble wastes move into the blood and the kidneys eliminate them from the body.
Bile serves to eliminate a variety of the toxic, fat-soluble wastes substances from the body. These substances include cholesterol, bile pigments, toxic chemicals, drugs, heavy metals, etc.
Hepatitis, fatty liver, Candida-yeast overgrowth, parasites, congestion, inflammation, infection of the gallbladder, high body’s acidity, poor eating habits, alcohol can cause the bile to be thick and acidic, therefore make it difficult for it to move through the ducts.
When the bile and pancreatic juice are getting acidic, they also become very “aggressive”, irritated, and corroded for the ducts, sphincter of Oddi, and small intestine causing jerky movement; “wrong way traffic” – bile/pancreatic juice refluxes in the stomach, ulcers and even cancers.
No surprise, it causes loss of appetite, nausea, gas, bloating, heartburn, attacks of pain, especially after “bad” foods or bad food combination. Pain can be last for 30 …
