Kidney dialysis is a medical procedure that acts as an artificial substitute for lost kidney function due to renal failure. It is often necessary when the kidneys are damaged, dysfunctional, or absent, resulting in the accumulation of toxic waste products in the body. Kidney dialysis is performed to mechanically filter waste and extra fluids from the blood – a process that would normally be carried out by healthy functioning kidneys. It involves circulating the patient's blood through a machine that filters out waste products and returns the clean blood back to the body. Symptoms indicating the need for dialysis might include abnormal blood test results, fatigue, nausea, loss of appetite, difficulty thinking clearly, swelling in the hands and feet, and shortness of breath. This treatment is not a cure, but it can help manage symptoms and improve the quality of life for individuals with severe kidney disease.
