What is a key function of kidney dialysis?

A key function of kidney dialysis is to remove waste from the blood. In patients with kidney failure, the kidneys cannot adequately filter out toxins, urea, and excess electrolytes from the bloodstream. Dialysis serves as an artificial replacement for the normal blood-filtering function of healthy kidneys. This process helps maintain a balance of fluids and electrolytes, prevents the buildup of harmful substances, and can stabilize the overall health of patients until they can receive a kidney transplant or their kidney function improves. By effectively removing these waste products, dialysis plays a critical role in managing renal disease and supporting patients' health.
