In medicine, gallstones (choleliths) are crystalline bodies formed within the body by accretion or concretion of normal or abnormal bile components.
Gallstones can occur anywhere within the biliary tree, including the gallbladder and the common bile duct. Obstruction of the common bile duct is choledocholithiasis; obstruction of the biliary tree can cause jaundice; obstruction of the outlet of the pancreatic exocrine system can cause pancreatitis. Cholelithiasis is the presence of stones in the gallbladder or bile ducts: chole- means "bile", lithia means "stone", and -sis means "process".
Gallstones usually remain asymptomatic initially. They start developing symptoms once the stones reach a certain size (>8 mm).A main symptom of gallstones is commonly referred to as a gallstone "attack", also known as biliary colic, in which a person will experience intense pain in the upper abdominal region that steadily increases for approximately thirty minutes to several hours. A patient may also experience pain in the back, ordinarily between the shoulder blades, or pain under the right shoulder. In some cases, the pain develops in the lower region of the abdomen, nearer to the pelvis, but this is less common. Nausea and vomiting may occur. Patients characteristically exhibit a positive Murphy's sign: the patient is instructed to breathe in while the gall bladder is deeply palpated. If the gallbladder is inflamed, the patient will abruptly stop inhaling due to the pain, a positive Murphy's sign.
These attacks are sharp and intensely painful, similar to that of a kidney stone attack. Often, attacks occur after a particularly fatty meal and almost always happen at night. Other symptoms include abdominal bloating, intolerance of fatty foods, belching, gas, and indigestion. The patient should also make sure to drink an appropriate amount of water relative to the number of calories being taken in. If the above symptoms coincide with chills, low-grade fever, yellowing of the skin or eyes, and/or clay-colored stool, a doctor should be consulted immediately.
Some people who have gallstones are asymptomatic and do not feel any pain or discomfort. These gallstones are called "silent stones" and do not affect the gallbladder or other internal organs. They do not need treatment.
