GFR stands for glomerular filtration rate, it is a number level that is obtained from the amount of creatinine in your blood calculated by your age and sex to determine what stage of kidney disease a person is at.
Specifically, it estimates how much blood passes through the glomeruli each minute. Glomeruli are the filters in your kidneys that filter waste and toxins from your blood.
Diabetes over time damages your nerves and vessels which then starves these filters of rich oxygenated blood to keep them in a healthy state and functioning properly. Diabetes is the main cause of kidney disease and over 40% of diabetics will get some stage of kidney disease.
A normal GFR rate for an adult is 90 or higher
If your GFR rate is between 60 and 89 this may be normal for people over the age of 60, because as we age our GFR levels become lower even for people without diabetes.
A GFR level below 59 is classed as abnormal, if it stays the same for 3 months, this is classed as having chronic kidney disease.
Kidney Disease often progresses slowly over a period of years. This is good news because if CKD is caught early, lifestyle and medicine changes may help slow its progress.
Once you are classified as having kidney disease you then fall into 1 of the 5 stages of kidney disease depending on your GFR level…. Read more about the 5 stages of kidney disease here
