What are the symptoms of gallstones?
Comment on this Read 28 Comments
The majority of people with gallstones have no signs or symptoms and are unaware of their gallstones. (The gallstones are "silent.") The gallstones often are found as a result of tests (for example, ultrasound or X-ray examination of the abdomen) performed while evaluating medical conditions other than gallstones. Symptoms can appear later in life, however, after many years without symptoms. Thus, over a period of five years, approximately 10% of people with silent gallstones will develop symptoms. Once symptoms develop, they are likely to continue and often will worsen.
Gallstones are blamed for many symptoms they do not cause. Among the symptoms gallstones do not cause are:
When signs and symptoms of gallstones occur, they virtually always occur because the gallstones obstruct the bile ducts.
The most common symptom of gallstones is biliary colic. Biliary colic is a very specific type of pain, occurring as the primary or only symptom in 80% of people with gallstones who develop symptoms. Biliary colic occurs when the extrahepatic ducts-cystic, (hepatic duct or common bile duct) are suddenly blocked by a gallstone. Slowly-progressing obstruction, as from a tumor, does not cause biliary colic. Behind the obstruction, fluid accumulates and distends the ducts and gallbladder. In the case of hepatic duct or common bile duct obstruction, this is due to continued secretion of bile by the liver. In the case of cystic duct obstruction, the wall of the gallbladder secretes fluid into the gallbladder. It is the distention of the ducts or gallbladder that causes biliary colic.
Characteristically, biliary colic comes on suddenly or builds rapidly to a peak over a few minutes.
Biliary colic is a recurring symptom. Once the first episode occurs, there are likely to be other episodes. Also, there is a pattern of recurrence for each individual, that is, in some individuals the episodes tend to remain frequent while in others they are infrequent. The majority of people who develop biliary colic do not go on to develop cholecystitis or other complications.
