Cholecystitis is a relatively common disease with a high incidence. The disease can be divided into two types, acute and chronic, and often coexists with cholelithiasis. It is often accompanied by severe pain or colic in the right upper abdomen, often with sudden onset, very intense, or colic-like, some manifesting as persistent swelling and pain, radiating, with the most common radiating sites being the right shoulder and the subscapular angle of the right scapula. The clinical manifestations of chronic cholecystitis are not specific, but commonly include vague pain in the right upper abdomen, fullness and discomfort after eating, belching, nausea after eating fatty food, and occasionally vomiting. Its diet is very critical in the treatment. In acute attacks of cholecystitis, fasting is the first step to ensure adequate rest of the gallbladder and relieve pain. Intravenous nutrition. Drink more water and have a light liquid diet, such as rice soup, lotus root powder, soy milk and other foods. After the condition improves, a low-fat semi-liquid diet or low-fat soft food with less residue can be given. Chronic cholecystitis: first of all, low-salt and low-fat diet, foods containing more fat can cause gallbladder contraction and induce gallbladder pain. Therefore, animal fats should be strictly limited, and vegetable fats can be used in moderation.

Plant fiber can inhibit the absorption of cholesterol, lower lipids, improve bile and laxity, and prevent the onset of cholecystitis. Choose foods high in dietary fiber, such as green leafy vegetables, radish, beans, fruits, coarse grains and mushrooms, fungus and other foods with cholesterol-lowering effects. Drink more water, which can dilute bile and facilitate the recovery of biliary tract diseases, 1000~1500 ml per day is appropriate.
