Patients with cholecystitis should avoid seafood as much as possible because many seafoods are high in cholesterol, such as squid, scallops, crab yolk and fish eggs, which can easily aggravate the symptoms of cholecystitis or induce acute cholecystitis after consumption. In addition, it should be noted that patients with cholecystitis should avoid eating fatty meats, animal offal and fried foods, and a regular diet is also very important. If cholecystitis recurs, surgical treatment should be considered, with laparoscopic cholecystectomy being preferred. The majority of patients after cholecystectomy can resume a normal diet and can consume seafood as appropriate, but care should be taken to avoid eating raw seafood, as this may cause parasitic infections and hyperlipidemia, which can affect health. It is worth noting that patients with gout and pancreatitis should also avoid seafood as much as possible, otherwise it will aggravate the symptoms and a light and easily digestible diet should be the main focus.
