Abdominal edema is clinically known as ascites and usually requires liver protection, enzyme lowering, diuretic or even surgical treatment to obtain symptomatic relief or even cure. The most common diseases in which ascites occurs clinically are post-hepatitis cirrhosis and hypoproteinemia caused by malignant tumors of the gastrointestinal tract. For hypoproteinemia caused by post-hepatitis cirrhosis, treatment usually involves liver protection, enzyme lowering and diuresis, such as furosemide, hydrochlorothiazide and spironolactone, which can provide symptomatic relief, while for hypoproteinemia caused by malignant tumors, it is mainly caused by insufficient food intake, which leads to insufficient synthesis of albumin by the liver, resulting in ascites. If further examination, such as enhanced CT of the abdomen, confirms that radical surgery can be done for intestinal tumors, radical treatment of gastric cancer or radical treatment of intestinal cancer, together with postoperative chemotherapy or even radiotherapy, is usually required to obtain a cure.
