With multiple hepatic cysts, attention should be paid to adjusting the diet structure and it is best to stay away from foods with high cholesterol. Because multiple hepatic cysts may have certain compression symptoms in the adjacent bile duct system or may be accompanied by bile duct dilatation, high fatty food or high cholesterol food may easily induce the occurrence of cholecystitis or bile stasis, which affects the metabolism and balance of bile pigments and bile acids, and may also easily cause secondary infection. In the case of hepatic cysts, if the infection is secondary, the patient may show significant fever and pain in the right upper abdomen, and in severe cases, there may be adverse reactions such as infectious shock. In the case of huge liver cysts with secondary infection, timely surgical removal or incision and drainage is needed to remove the infectious factors, so patients with polycystic liver should also pay strict attention to the diet structure in general.
