Renal insufficiency is caused by a variety of causes, the glomerular serious damage, disorder group of the body in the excretion of metabolic waste and adjust the water and electrolyte, acid-base balance and other aspects of the clinical syndrome.
Renal insufficiency of the four staging symptoms:
Phase I: Renal function reserve compensatory period. Because the kidney reserve compensation capacity is very large, so the clinical decline in renal function, but its excretion of metabolites and regulation of water, electrolyte balance can still meet the normal needs, clinically does not appear symptoms, renal function tests are normal Range or occasional slightly higher phenomenon.
Phase II: renal insufficiency. Glomerular has more damage, 60% -75%, renal excretion of metabolic waste has a certain obstacle, creatinine urea nitrogen can be high or beyond normal. The patient can appear anemia, fatigue, weakness, weight loss, the spirit is not easy to focus and so on. But often overlooked, if there is water loss, infection, bleeding, etc., then soon obvious symptoms.
Phase III: renal failure period. Kidney function has been very serious damage, 75% -95%, can not maintain the body's internal environment is stable, the patient fatigue, fatigue, attention can not concentrate and other symptoms intensified, anemia significantly increased nocturia, serum creatinine, And often acidosis. This period also known as azotemia period.
Four: uremia or renal insufficiency end. This period of glomerular damage has more than 95%, with severe clinical symptoms, such as severe nausea, vomiting, oliguria, edema, malignant hypertension, severe anemia, skin itching, mouth urine urine smell and so on.
