Patients with end-stage uremia can live about 10-20 years. Once patients with chronic renal failure enter the uremic phase, the ability of kidney detoxification and drainage has been lost, so they can only be treated with hemodialysis. But hemodialysis is not sufficient for the removal of toxins, the ability to remove toxins is only about 1/10 of the normal kidney, that is to say, even with dialysis, about 9/10 of the toxins still accumulate in the body, which has a great impact on the body, especially for the cardiovascular and cerebrovascular impact is more obvious, will cause the strengthening of vascular sclerosis, brain infarction, brain hemorrhage, myocardial infarction and so on. These are more serious and lethal diseases and are a very common cause of death in uremic patients. The appearance and intensification of these diseases limits the survival time of the patient. In addition to this, if patients are not careful with their diet, excessive potassium intake can cause hyperkalemia, which tends to cause sudden death due to malignant cardiac arrhythmias. These are some of the more common and life-threatening complications for patients with uremia. These complications cause patients to survive even on regular hemodialysis for rarely more than 20 years, approximately between 10 and 20 years.
