Low albumin in the human body, there can be fatigue, generalized edema, and depressed edema, most commonly seen in nephrotic syndrome, liver disease and malignant wasting state of the patient, can be treated by oral high protein food, as well as intravenous injection of human blood albumin and other symptomatic treatment. Aggressive search for the primary cause is instructive for the next step of treatment, if the patient is caused by nephrotic syndrome, consider the immune system disease.
