Dialysis is a machine that purifies the blood, explains Dr. Christian Suarez, Nephrologist with Baptist Health South Florida. After the blood is clean, it gets back to the patient. Filters remove extra fluids and extra electrolytes.
Dialysis is needed for patients who get the stage 5 of kidney disease. Physicians evaluate the functioning of the kidney to determine if dialysis is necessary, he describes.
There are some symptoms such as nausea, vomiting, insomnia, headache, chest pain, swelling on the legs or the patient starts to build up fluid which can help to make diagnosis.
