Strictly speaking, there is no such thing as 22 symptoms of cholecystitis; there are not that many symptoms of cholecystitis. Cholecystitis can be divided into acute cholecystitis and chronic cholecystitis. In general, the early symptoms of cholecystitis are mainly sudden discomfort or pain in the right upper abdomen, accompanied by radiation to the right shoulder and back, mostly occurring after high fatty foods, full meals or at night, but some people do not show obvious symptoms in the early stages due to physical differences. The symptoms of acute cholecystitis are usually typical, with abdominal pain, fever, etc. The fever usually does not exceed 39°C, but the fever is accompanied by digestive symptoms such as nausea, vomiting and constipation, while a small number of people may also have varying degrees of jaundice, manifested as yellowing of urine, skin mucous membranes and eyes, suggesting the possible development of cholecystocholedochal fistula, common bile duct stones, cholangitis, pancreatitis, etc. Complications. Some patients with more serious conditions may develop gallbladder gangrene or perforation, which may manifest as severe abdominal pain, high fever and chills. The symptoms of chronic cholecystitis, on the other hand, are relatively difficult to distinguish from other gastrointestinal diseases, mainly manifesting as discomfort or pain in the upper abdomen, usually without pain radiating to the back of the shoulder, but accompanied by vomiting, nausea and other discomforts, and rarely with high fever and jaundice. Some patients have biliary dyspepsia due to chronic cholecystitis caused by gallbladder stones, often manifesting as belching and a feeling of bloating after meals. If patients experience pain, nausea, vomiting and other uncomfortable symptoms in the above mentioned areas, it is recommended to visit a hospital promptly for relevant examinations to clarify the cause and then undergo medication and surgical treatment.
