K80.1: Calculus of gallbladder with other cholecystitis

Calculus of the gallbladder with other cholecystitis (K80.1) describes a medical condition where the individual has gallstones, which are hardened deposits, in the gallbladder and also suffers from inflammation of the gallbladder, known as cholecystitis. Gallstones form when substances in the bile—primarily cholesterol and bilirubin—crystallize in the gallbladder, while cholecystitis occurs as a result of obstruction of the gallbladder ducts due to these stones, which leads to a buildup of bile. Common symptoms of this condition include pain in the right upper quadrant of the abdomen, nausea, vomiting, and fever. This condition primarily affects the digestive system, mainly the gallbladder, and can progress to chronic cholecystitis if left untreated, causing long-term damage to the gallbladder.
