Most liver cysts have no effect on patients, and the danger of liver cysts to patients can be divided into the following cases: 1. liver cysts are relatively large and produce pressure on surrounding organs, such as the stomach, causing a feeling of fullness after eating, and not being able to eat or eat much; 2. liver cysts can cause secondary infection, which is relatively rare, and after secondary infection, there are manifestations similar to liver abscesses, abdominal pain, fever and chills, and this situation requires early drainage treatment; 3. Patients with liver cysts can cause secondary intracapsular hemorrhage, which is relatively rare. For most patients, liver cysts that are relatively small are not particularly harmful and do not cause infection, bleeding, or produce compression symptoms, so there is no need to worry excessively.
