Patients with kidney disease like PKD, IGA, FSGS, kidney cyst can develop into kidney failure finally. At stage 4 or 5 ( end stage) kidney failure, dialysis is always suggested for patients to replace kidney to filter the blood, removing wastes and fluids from body. Then how does dialysis work exactly? Here we will explain how hemodialysis work for you.

There are two leading principles of hemodialysis:

1. diffusion

Diffusion describes that particles go across the membrane with little holes in semi permeable, to make particle concentration on two sides of membrane is the same.

2. ultrafiltration

It means that excessive fluids in blood get pumped into membrane with the help of blood pump. However, peritoneal dialysis is different, which has no property of ultrafiltration. Fluids in blood are eliminated by osmosis, that some chemicals are used to make fluids get across membrane.

Dialysis can be annoying and complicated for patients. You can choose the right one which is fit for you: HD or PD. Side effects can be resulted in by dialysis, such as low blood pressure, skin problems, muscle cramps, nausea and vomiting, restless leg syndrome. Patients on dialysis should get prepared for facing these side effects, and talk with doctors in detail to find a good way to prevent and treat these.
