GFR is often used for assessing patient’s kidney condition, and kidney disease is divided into five stages according to patient’s GFR.
What is GFR?
GFR refers to the amount of filtered fluid that is produced in unit time. For healthy people, there are about 660ml blood will flow though patient’s glomeruli in every minute, and about one fifth blood will be filtered by glomeruli and then crude urine will be produced.
For healthy people, the produced crude urine is about 180L every day, but there are about 1~2L terminal urine will be excreted out.
What is the relationship between GFR and patient’s kidney function?
As we have said, kidney disease is divided into five stages according to patient’s kidney function. Kidney disease can damage patient’s kidney structure, which will decrease patient’s kidney function.
For patients who are in the first stage of kidney disease, their GFR is about 90~125ml/min, and for patients in stage two patient, their GFR is between 60~89ml/min, and patient’s GFR is 30~59ml/min when he is in stage three, and GFR is 15~29ml/min for patient who is in stage four, and it is below 15ml/min when patient is in the end stage.
Can patient’s GFR be elevated?
The severer patient’s kidney damage is, the lower patient’s GFR will be. If patient wants to elevate is GFR, the only way is to improve patient’s kidney function.
In fact, the decrease of patient’s kidney function is due to the damage in patient’s nephrons. To increase GFR, patient needs to repair his damaged nephrons. In fact, if only the nephrons have not been necrotic, they are able to be repaired.
