2. The characteristic of nephrogenic edema is eyelid and facial edema when getting up in the morning in the early stage of the disease, which later develops into systemic edema (severe edema in nephrotic syndrome). There are often symptoms of urine changes, hypertension, and renal impairment.

3. Hepatic edema is mainly manifested as ascites, and may first appear in the ankles and gradually spread upward, while the head, face and upper limbs are often free of edema. The clinical signs of cirrhosis mainly include decreased liver function and portal hypertension.

4. The characteristics of malnutrition edema are that there are often symptoms such as emaciation and weight loss before edema occurs.
