When inducing gallbladder inflammation or obstructing the common bile duct, gallstones will affect the patient’s digestive function to a certain extent. 1. Inflammation of the gallbladder: When stones repeatedly irritate the gallbladder wall and cause acute and chronic inflammation of the gallbladder, i.e. acute and chronic cholecystitis, the first symptoms of the patient are nausea and vomiting, poor appetite, aversion to greasy food and other symptoms related to indigestion. 2. Blockage of the common bile duct: When stones fall and partially or completely block the common bile duct, it will cause a significant decline in digestive function due to insufficient bile discharge, especially for the digestion of greasy food. Patients may experience symptoms such as aversion to greasy food and poor appetite. It is recommended that patients with gallstones should consult a doctor in time and under the guidance of a professional doctor to complete the relevant examinations and decide on the next step of treatment by taking into account the specific signs and symptoms of gallstones.
