Kidney failure facts. 1  Kidneys are the organs that filter waste products from the blood. 2  Symptoms of kidney failure are due to the build-up of waste products and excess fluid in the body that may cause weakness, shortness of breath, lethargy, swelling, and confusion. Inability to remove potassium from the bloodstream may lead to abnormal heart rhythms and sudden death.
Chronic kidney disease (CKD) usually gets worse slowly, and symptoms may not appear until your kidneys are badly damaged. In the late stages of CKD, as you are nearing kidney failure (ESRD), you may notice symptoms that are caused by waste and extra fluid building up in your body.
