They produce urine, thereby removing excess water and toxins, produce hormones, regulate mineral levels and blood pressure, make VitaminD, and maintain the body’s acid-base balance.
Every day these versatile organs cleanse all the body’s blood about three-hundred times.If the kidneys become diseased or fail, it’s serious health problem because excess water and waste products from the body’s metabolism can no longer be filtered out of the blood.
The most widely used form of dialysis therapy is called hemodialysis. At the center of hemodialysis is a dialysis filter, known as a dialyzer. Serving as an artificial kidney, it cleanses the patient’s blood during the treatment.
Inside a plastic tube, 30 centimeters long– about 12 inches – the blood flows through up to twenty-thousand hair-fine fibers.
Microscopic pores in the fibers filter out metabolic waste and excess water, which the dialysis fluid then carries away.A treatment can take from three to six hours, usually three times a week.
Chronic kidney failure afflicts more than three million people worldwide. Fresenius Medical Care is the world leader in dialysis.
About half of all dialyzers and dialysis machines sold worldwide are made in our plants. In our more than thirty-five hundred dialysis clinics, we treat over three-hundred thousand patients. Every 0.7 seconds we start dialysis treatment for a patient somewhere in the world.
