The symptoms of cholecystitis are divided into chronic cholecystitis and acute cholecystitis, and they present differently clinically. During acute cholecystitis, there is pain in the right upper abdomen in the gallbladder area, accompanied by fever, fatigue, decreased appetite, and even jaundice. Physical examination can reveal obvious tenderness and rebound pain in the right upper abdomen at the gallbladder. In contrast, chronic cholecystitis may not have obvious symptoms. Occasional pain may occur in the gallbladder area, but it is bearable. Typically, there is no obvious tenderness in the area, and the condition usually requires diagnosis through examinations such as an ultrasound.
