Hemodialysis is a medical procedure where health kidneys remove the extra fluid and other waste products from the blood to correct electrolyte imbalances. They also make substances that keep your body healthy. There are two distinct kinds of dialysis-hemodialysis and peritoneal dialysis. Hemodialysis is generally used to treat both acute (temporary) and chronic (permanent) kidney failure. To remove the waste products and fluid dialysis takes over a portion of the failing kidneys. When the function of the kidney is approximately lost to 90% then dialysis is typically needed. It may be acute renal failure or acute kidney injury or chronic kidney disease i.e. the kidney function can be lost from over months to years rapidly. In this scenario, treatment for kidney diseases involves replacement therapy. In acute kidney failure short time dialysis is needed until the kidneys get better. But in the case of chronic if kidney failure progresses overtime it requires kidney transplantation.
