Most of the lower limb swelling in patients with cirrhosis is caused by hypoproteinemia, which needs to be corrected with appropriate albumin supplementation and the use of diuretics. In the process of using diuretics, it is necessary to pay attention to the side effects of electrolyte disorders, so it is generally recommended to use a combination of diuretics, such as furosemide and spironolactone, which can reduce the incidence of electrolyte disorders. In addition, we need to pay attention to exclude the possibility of lower limb swelling caused by cardiac insufficiency, we need to further improve the cardiac ultrasound and other related examinations to clarify. If hypoproteinemia is the cause, the clinical symptoms of most patients will gradually improve after the above treatment. If there is a combination of cardiac insufficiency, it is necessary to consult the cardiology department for related treatment.
