Liver cirrhosis can lead to general weakness due to electrolyte disorders or severe liver function impairment, causing the symptoms mentioned above. Once general weakness occurs, it is necessary to go to the hospital for comprehensive auxiliary examinations, such as liver function tests, routine blood tests, and electrolyte tests. Additionally, imaging studies of the abdomen should be performed to determine whether conditions like ascites, anemia, or hyponatremia exist. Different treatments are administered based on different disease diagnoses. For instance, if the weakness is due to severe ascites causing dilutional hyponatremia, sodium supplementation might be necessary, along with appropriate ascites drainage.
