The causes of dialysis induced edema?

(1) Excessive intake of water and salt: peritoneal dialysis on sodium clearance is low, especially when the patient has been more obvious retention of water. Many patients often because of thirst, or difficult to change the past habits, or lack of understanding of the importance of the liquid control and other reasons, can not be well controlled water and salt intake, leading to edema. Once appear the edema, it is often more difficult to cure.

(2) Water and salt removal decrease: with long time peritoneal dialysis , residual renal function in patients decreased or even loss, even peritoneal function in patients without any change, the total water removals will decline due to residual renal function decreased. On the other hand, due to changes in peritoneal transport function, resulting in reduced water clearance. Coupled with increased lymphatic reflux and lymphatic reabsorption, resulting in patients with excess capacity then edema.

(3) Appear new complications: such as cardiac insufficiency or original heart disease, hypoalbuminemia, mechanical or anatomic complications, reduce peritoneal ultrafiltration volume,.

(4) Age: compared to the normal adult body weight accounted for the proportion of liquid (60% male, 55% female), old aged fluid volume accounted for only 45%, the body fluid volume in elderly people is mainly to reduce cell dehydration shrinking, intracellular fluid decrease, extracellular fluid increased relatively easily in the dominant state of edema. Therefore, the elderly peritoneal dialysis patients is more easily in the dominant state of edema, sometimes only rely on the clinical symptoms and signs to determine the capacity of state is not accurate, need to rely on physical and chemical examination.

So, some people will certainly ask, is traditional Chinese medicine good or western medicine? In fact, they each have their own advantages and benefits, western medicine is a temporary solution but can control the condition of rapid development, traditional Chinese medicine can treatment the disease from the root, can be solved from the cause......
