What are the main clinical symptoms of gallstones? As we all know, gallstones are mainly due to the blockage of bile ducts by bile stones, resulting in bile stasis and increased bile duct pressure, which induces inflammation of bile ducts and gallbladder. Patients may present with acute inflammation such as nausea, vomiting, right upper abdominal pain, lower back pain, fever and chills. If the bile duct stones are not removed in time, the biliary tract infection can further aggravate and cause serious damage to liver function. Severe patients may even develop serious complications such as infectious shock, sepsis, and systemic inflammatory stress syndrome. In case of severe infection caused by gallbladder stones, clinical manifestations such as acute purulent cholecystitis, gallbladder perforation, gangrenous cholecystitis, and limited peritonitis can develop. If the stone is located at the end of the common bile duct, it can cause poor bile excretion and develop obstructive jaundice and acute cholangitis. If the stone blocks the pancreatic duct, it will cause poor excretion of pancreatic juice, resulting in the occurrence of biliary pancreatitis. Once biliary pancreatitis occurs, it often indicates that the patient is in a serious condition and may have serious complications such as abdominal fluid, abdominal pus, abdominal bleeding, peripancreatic pus and pancreatic necrosis. Thus, it can be seen that gallstones can cause more serious complications if left untreated. Therefore, for gallbladder stones or bile duct stones that have been found, patients are advised to get rid of the stones in time to avoid inducing serious complications and damage to their health.
