What are the stages of chronic renal failure? The first stage – renal function reserve compensation period. Because the kidney reserve compensatory capacity is large, so clinically the renal function is reduced, but its ability to excrete metabolites and regulate water and electrolyte balance can still meet normal needs, and clinically there are no symptoms, and renal function tests are in the normal range or occasionally slightly higher. The second stage – renal insufficiency stage. The glomerulus has been more damaged, 60%-75%, the kidneys have some obstacles in excreting metabolic waste, creatinine urea nitrogen can be high or exceed the normal value. Patients can appear anemia, fatigue, weight loss, mental concentration, etc.. However, they are often overlooked, and if there is water loss, infection, bleeding, etc., obvious symptoms will appear soon. Stage 3 – Renal failure stage. The kidney function has been damaged quite severely, 75%-95%, can not maintain the stability of the body’s internal environment, the patient easily fatigue, weakness, concentration and other symptoms increased, anemia is obvious, night urination increased, blood creatinine, urea nitrogen rose significantly, and often acidosis. This stage is also called the azotemia stage. Stage 4 – Uremic phase or end-stage renal insufficiency. At this stage, the glomerular damage has exceeded 95% and there are severe clinical symptoms, such as severe nausea, vomiting, little urine, swelling, pernicious hypertension, severe anemia, itchy skin, and urine smell in the mouth.
