According to the course of the different manifestations of chronic renal failure is also inconsistent

Chronic renal failure scorpion under different stages of the course . The clinical manifestations are not consistent , but mainly in the following aspects:
When the performance of a central nervous system when the blood urea nitrogen greater than 60mmo1 / L, to inject more power loss occurs , fatigue , memory loss and other symptoms. With the further deterioration of renal function. Can appear more knowledge barriers, such as cough sleep , sluggish , hallucinations, ataxia, and other symptoms. Uremia uremic encephalopathy may occur , mainly why sleep , Yu jump , flutter -like exhibition with aging and even coma . The main damage to the central nervous system uremia is caused by toxins in urine , while acidosis , the role of hyponatremia, hypomagnesemia and hypertension providers should not be ignored . Especially hyponatremia can cause central nervous system often willing to tip off the lesions.
2 . Cardiovascular system performance 800x-9095, end-stage renal failure patients with hypertension . Uremic patients often can be complicated by acute pulmonary edema. When expressed as difficulty in breathing, manifested as severe orthopnea , hemoptysis , sputum mild seizures. Uremic cardiomyopathy is mainly for the enlargement of the heart , diastolic gallop , hypotension and arrhythmia . Uremic patients with sudden leg pain should note that more uremic pericarditis . Clinically manifested as fever , chest pain , hypotension , pericardial heart shadow health fricative and expand . The disease and urinary toxins and related bleeding tendency . Long-term survival of dialysis patients with uremia atherosclerosis higher incidence . Is one of the main causes of death in long-term dialysis patients .
3 can occur when the lower respiratory acidosis performance uremia. Due to increased hydrostatic pressure in the lungs , plus some of circulating toxins can increase the permeability of the lung capillaries, it is easy to cause pulmonary edema , resulting in " uremic lung" , appears bare -like distribution of diffuse lung Run around the door stoves . Uremic patients often appear on the alveolar septa metastatic calcification , may be associated with hyperparathyroidism , hypercalcemia and alkalosis have a certain relationship . Pulmonary fibrosis and calcification . In addition congestive heart failure and pulmonary infection often causes pleural effusion .
4 . Quiet system performance with chronic renal failure can occur early loss of appetite, taste disturbance . Uremia may occur in severe complications , nausea , vomiting , diarrhea, vomiting, bloody diarrhea , etc. ; another urinary toxins can diffuse into the digestive tract, through the role of bacterial decomposition of urea , resulting in increased levels of ammonia in the gastrointestinal tract , and therefore prone to stomach intestinal inflammation and ulcers speech . Since the film is discharged through the gastrointestinal tract drilling poisons increased urea nitrogen and kidney can not be inactivated gastrin home, home gastrin in the blood rises , so gastritis , duodenitis , ulcers and gastrointestinal bleeding with multiple common speech . Furthermore cat intestine membrane damage , bleeding and fine turning infection. Colon played ulcers, hemorrhage, necrosis , infection and dysfunction as well as vomiting, diarrhea, mouth ammonia odor , intractable symptoms often do the reverse occurs .
