Yogurt can be consumed by cholecystitis patients, but milk is not recommended for cholecystitis patients. Because yogurt is fermented milk, this kind of material in the fat content is low, cause patients with biliary colic chance is low. In addition, if cholecystitis patients are combined with gallbladder stones, they should pay attention to eat less or not eat fried eggs, milk and fatty meat and other foods with high fat content. This is because if the patient eats these foods, it will cause the gallbladder to contract sharply, causing bile excretion. If the stone is embedded in the neck of the gallbladder, it will cause severe biliary colic, and will cause bile stasis in the gallbladder and thickening of the gallbladder wall. This is called an acute attack of chronic cholecystitis with embedded gallbladder stones, and the patient should be given antibiotics and painkillers to relieve the symptoms, and should be considered for open or laparoscopic cholecystectomy, and the gallbladder should be sent to the Department of Pathology for further examination after the operation.
