Chronic Kidney Disease

What is Chronic Kidney Disease (CKD)?

CKD means that your kidneys are damaged in some way, and unlikely to get better. Chronic means long lasting. What causes chronic kidney disease? Common causes include Diabetes, high Blood Pressure and various forms of inflammation. For some people the cause is never found. CKD is more common in older people.

What are the tests to check how well my kidneys are working?

To know how well your kidneys are working a blood test and urine test are done, as well as a check of your blood pressure. The blood test is the Creatinine level and provides an eGFR Creatinine is the most common test used to measure kidney function.

Creatinine is a normal waste product from the breakdown of protein in muscles and is removed from the body by the kidneys. If the kidneys are damaged then the creatinine level will rise.

eGFR stands for estimated glomerular filtration rate. It measures how much blood your kidneys filter each minute. If your kidneys are not working properly the eGFR will go down.


Stages of Kidney Disease


What is Acute Kidney Injury (AKI)?

Kidneys can either be injured over a long time, we call this chronic, or a short time we call this acute. A short time normally refers to days or weeks. Acute kidney injury is a common complication of other illnesses such as excessive diarrhoea and vomiting, particularly when people have other health conditions. When acute kidney injury is identified early it is often fully reversible.
