It is possible to eat fish after gallbladder removal. After gallbladder removal, the concentration and excretion of bile will be greatly affected, which will obviously affect the digestion of fatty foods. Therefore, at this time, it is not possible to eat high-fat, greasy food, such as animal offal, fat meat, squid, crab roe, butter and so on. Fish is a kind of high protein food, not only will not affect the patient’s digestive function after cholecystectomy, but also conducive to the patient’s postoperative recovery. After cholecystectomy, patients in the early stage should gradually transition from a liquid diet to a semi-liquid diet and a normal diet. Fish is not recommended in the early postoperative period, and rice porridge should be the mainstay of the diet, with a gradual transition. Fish after cholecystectomy should be mainly freshwater fish, such as carp, crucian carp, both fish meat and fish soup, but fish roe should be avoided because it is also a kind of high cholesterol food, which may affect the digestive function of patients after cholecystectomy.
