If your kidneys are damaged in
some way, or are affected by disease, they may be unable to maintain their
vital functions that keep you well.
kidneys progressively fail to filter the blood efficiently, they do not do
their job of removing excess water, waste products, and toxins. The levels of
these substances in your body increase, making you feel unwell. The condition
is called uremia. In the first instance, patients who have early stage Chronic
Kidney Disease (CKD) with mild uremia may be treated with drugs and diet
For many patients this is enough
to keep them feeling well indefinitely. For others, despite management with
diet and drugs, more kidney function is lost over time. If uremia becomes
severe, it reaches end stage renal failure (ESRD), and you must begin dialysis
to replace the job of your kidneys.
Hemodialysis is an extremely
effective treatment that uses an artificial kidney to cleanse waste products
and excess water and salt from the blood of patients with kidney failure. Tubes
are connected to a dialysis machine that withdraws and returns blood from
either a surgically created vein in the arm or a catheter placed in a vein in
the neck or chest.
