Nausea and vomiting also related with central nervous system disorder.
2、Cardiovascular system due to the kidney function decreased, acid-base disorder、metabolic disorders give rise to renal hypertension、acidosis、retention of water and sodium、anemia、hyperkalemia and the effect of toxicant, could cause to dizzy、headache、heart failure、arrhythmia、myocardial damage.
Because of the stimulation of urea, also cause to sterile pericarditis, when the condition gets more serious, there are cellulose and hemorrhagic effusion in the pericardial cavity.
3、Nervous system Due to electrolyte acid-base disorders; the accumulation of toxicant lead to the degeneration of nerve cell; renal hypertension give rise to the degeneration of brain cells and encephaledema, in the early phase of uremia, the patients will occur the symptoms of dizzy、headache、weak、hypomnesis, and with the deterioration of the illness also have tic、dysphoria; at last it will develop into apathia、drowsiness、coma.
