Colds usually do not directly cause cholecystitis, but may be caused by dietary factors, biliary ascariasis, gallbladder stones, gallbladder duct torsion and other reasons. 1. Dietary factors: eating greasy food and overeating during cold and flu can trigger cholecystitis, which manifests itself as pain in the right upper abdomen, which can radiate to the right shoulder blade and back pain. 2. Biliary ascariasis: Ascaris lumbricoides enter into the biliary tract leading to biliary tract obstruction and infection, which in turn triggers cholecystitis. 3. Gallbladder stones: obstruction or embedded stones in the gallbladder, leading to obstruction of bile discharge and infection, which may induce cholecystitis. 4. Torsion of the gallbladder duct: when the gallbladder duct is twisted, bile stagnates and forms a high concentration of bile, which can damage the mucous membrane of the gallbladder and induce cholecystitis. Cholecystitis, it is recommended to consult a doctor in time to identify the cause of the disease, and follow the doctor’s instructions for treatment.
