When patients with cholecystitis and cholelithiasis eat greasy food, it is not only not easy to digest, but also causes spasmodic colic (i.e. biliary colic) in the right upper abdomen because patients with cholecystitis and cholelithiasis have lesions in the mucous membrane of the gallbladder, the contraction function of the gallbladder is poor, and the discharge of bile is somewhat impaired. Especially for patients with obstruction in the bile duct, they certainly have less bile salt, one of the main components of bile. Bile salt has the function of promoting fat digestion and decomposition, and if it is lacking, the digestive ability of greasy food is naturally weakened.
