A gallstone is a stone formed within the gallbladder out of bile components. The term cholelithiasis may refer to the presence of stones in the gallbladder or to the diseases caused by gallstones. Most people with gallstones (about 80%) never have symptoms. In 1–4% of those with gallstones, a crampy pain in the right upper part of the abdomen, known as biliary colic, occurs each year. Complications of gallstones include inflammation of the gallbladder, inflammation of the pancreas, and liver inflammation. Symptoms of these complications may include pain of more than five hours duration, fever, yellowish skin, vomiting, or tea-color urine.
Risk factors for gallstones include birth control pills, pregnancy, a family history of gallstones, obesity, diabetes, liver disease, or rapid weight loss. Gallstones are formed in the gallbladder, typically from either cholesterol or bilirubin. Gallstones may be suspected based on symptoms. Diagnosis is then typically confirmed by ultrasound. Complications may be detected on blood tests.
Prevention is by maintaining a healthy weight and eating a diet high in fiber and low in simple carbohydrates. If there are no symptoms, treatment is usually not needed. In those who are having gallbladder attacks, surgery to remove the gallbladder is typically recommended. This can be either done through several small incisions or through a single larger incision. Surgery is typically done under general anesthesia. In those who are unable to have surgery, medication to try to dissolve the stones or shock wave lithotripsy may be tried.
