The dangers of hypoproteinemia include causing the body to experience symptoms such as swelling and wasting, and it is also prone to inducing infections and other diseases. Hypoproteinemia is caused by the total plasma protein, especially plasma albumin falling below the normal value. When plasma albumin falls, the effective osmotic pressure can be reduced, and the body will retain too much water between the tissues, leading to the patient’s symptoms of edema. In addition to this, it may be accompanied by ascites, pericardial effusion, pleural effusion and so on. Patients with prolonged hypoproteinemia may experience wasting, poor wound healing, incision, abdominal, and lung infections, and malnutrition. Patients diagnosed with hypoproteinemia should actively cooperate with their doctors.
