With the aggravation of the disease, there may be restlessness, muscle tremor, convulsion, and finally develop to apathy, drowsiness and coma. The occurrence of these symptoms is related to the following factors: ① the accumulation of some toxic substances may cause neurodegeneration; ② electrolyte and acid-base balance disorder; ③ cerebral vasospasm caused by renal hypertension, hypoxia and increased capillary permeability may cause neurodegeneration and brain edema.

Second: the earliest symptom of the digestive system in uremic patients is loss of appetite or indigestion. Many patients will think that this is the symptom of stomach disease; when the condition worsens, anorexia, nausea, vomiting or diarrhea may appear. The occurrence of these symptoms may be related to the decomposition of urea into ammonia by the urease of bacteria in the intestine, and the inflammation and multiple small superficial ulcers caused by the stimulation of gastrointestinal mucosa by ammonia. Patients often complicated with gastrointestinal bleeding. In addition, nausea and vomiting are also related to the dysfunction of the central nervous system.

Third, uremic patients can suffer from heart failure, arrhythmia and myocardial damage due to renal hypertension, acidosis, hyperkalemia, sodium retention, anemia and toxic substances *. Due to the stimulating effect of urea (and possibly uric acid), aseptic pericarditis can also occur.
