What are the symptoms of kidney failure patients is not the same period?

　　Renal failure is divided into four periods, then suffering from renal failure, renal failure, what the patient's symptoms are not the same period? Can be divided into acute and chronic renal failure, acute renal failure progression fast, usually caused by renal blood supply is not feet (such as trauma or burns), for some reason, kidney function is impaired or blocked causing hurt by poison, causing acute renal failure generation. The main raw chronic renal failure due to prolonged kidney disease, along with the time and the disease gradually reduced kidney function, resulting in the generation of renal failure. ? No matter what the disease has its symptoms, renal failure is not an exception, and what the patient's symptoms of kidney failure that is not the same hospital on kidney specialists for friends to explain:
　　(1): renal decompensation:
　　Decompensated renal glomerular filtration rate (detoxification capacity) changed little as 30-60 ml / min, while the normal glomerular filtration rate (detoxification capacity) to 120 liters per minute. This change in renal tissue of about 20% -25% less. Kidney Despite the loss of reserve capacity, but for the excretion of metabolites, regulation of water, electrolyte and acid-base balance is still good, so no specific clinical manifestations, serum muscle enzymes and occult blood urea nitrogen usually normal or mildly elevated sometimes.
　　(2): azotemia:
　　Azotemia glomerular filtration rate (detoxification capacity) changed little as 25 ml / min, 50% -70% of renal tissue becomes less concentrated kidney dysfunction, showing nocturia or urine, is not the same degree of anemia, often azotemia, serum creatinine, blood urea nitrogen levels. Clinical may have weakness, loss of appetite, mild nausea and general discomfort. This neglect of renal function, such as overhead protection or body, may exhibit severe vomiting, diarrhea, blood volume caused no feet, if infection or vice efficacy of the use of toxic drugs to the kidneys, can cause rapid kidney function decline and recession .
　　(3): impairment of renal function (creatinine uremia high early):
　　Impaired renal function of glomerular filtration rate (detoxification capacity) becomes less to 10-15 ml per minute, kidney tissue becomes about 70% -90% less severely impaired renal function, no way to maintain the body's metabolism and water and electrolyte and acid-base balance. Perhaps not maintain a stable internal environment, resulting in serum creatinine, blood urea nitrogen increased significantly, concentrated urine dilution dysfunction, acidosis, sodium retention, low calcium, high phosphorus, potassium and other balance disorders performance. May have significant anemia and gastrointestinal manifestations, such as nausea, vomiting, loss of appetite. May also have neuropsychiatric manifestations, such as weakness, lack of concentration, lack of energy and so on.
　　(4): uremia high creatinine period
　　Glomerular filtration rate (detoxification capacity) decreased to 10 ml -15 ml per minute or less, kidney tissue becomes less than 90%, this period is the end of chronic renal failure, renal failure symptoms become more evident over, showing how dirty the whole body function decline, such as gastrointestinal, neurological, cardiovascular, hematopoietic system, respiratory system, skin and metabolic system imbalance. Clinically manifested as vomiting, nausea, irritability, increased blood pressure, palpitation, chest tightness, no method supine, breathing difficulties, severe anemia, convulsions, coma patients with severe, often hyperkalemia, hyponatremia, hypocalcemia, high hyperphosphataemia. The need to rely on dialysis to sustain life. Often due to hyperkalemia, cerebral edema, pulmonary edema, cardiac function decline and suddenly died.

　　What are the symptoms of kidney failure patients is not the same period? Above are my kidney specialist hospital for friends to explain the symptoms of kidney failure, hoping to help friends.
