Chronic cholecystitis should avoid overfeeding, eating greasy food, etc., so as not to induce its acute attack. Chronic cholecystitis is a persistent and recurrent chronic inflammatory disease of the gallbladder, and more than 90% of the patients are accompanied by gallbladder stones. Since eating high-fat food will lead to contraction of the gallbladder, the patients often have abdominal distension and abdominal pain after eating greasy food. If the gallbladder contraction leads to gallbladder stones embedded in the neck of the gallbladder, it will cause acute calculous cholecystitis, and in severe cases, gangrene and perforation of the gallbladder will occur, which will require surgical treatment. In addition, repeated episodes of chronic cholecystitis will eventually lead to gallbladder atrophy and complete loss of function. Therefore, patients diagnosed with chronic cholecystitis should avoid overeating, eat a light diet, try to early cholecystectomy, patients who can not tolerate surgery can use antibiotic treatment.
