Bad gall may manifest as abdominal pain, abdominal distension, jaundice, nausea, vomiting and other symptoms. According to the different causes of cholecystitis, gallbladder stones and gallbladder cancer, the clinical manifestations are different, which are analyzed as follows: 1. Cholecystitis: cholecystitis is mostly caused by bile stasis due to bile duct obstruction, bacterial infection and other pathogens, and patients may have fever, right upper abdominal pain, radiating right shoulder pain and other manifestations. 2. Gallbladder stones: gallbladder stones are caused by the abnormal composition of bile, and can be formed when there is more cholesterol and bilirubin in the bile. When gallstones are small and few in number, patients usually have no clinical symptoms. If gallstones are large and block the bile ducts, they can cause upper abdominal cramps, jaundice and other symptoms. 3. Gallbladder cancer: gallbladder cancer can cause hidden pain in the upper abdomen, jaundice and clay-like stools when it invades the bile ducts, and with the progress of the disease, there can be clinical manifestations such as poor appetite, anemia and emaciation, etc. Therefore, patients with upper abdominal pain, jaundice and other symptoms are usually not clinically symptomatic. Therefore, when patients have epigastric pain, jaundice and other symptoms, it is recommended to go to regular hospitals in time to clarify the cause of disease as soon as possible and treat it actively. Do not delay, so as not to miss the condition.
