Great question! CKD 3b refers to Stage 3b of Chronic Kidney Disease. CKD is a general term for a gradual loss of kidney function, and it's broken into stages based on how well the kidneys are filtering blood — measured by a score called GFR (glomerular filtration rate).
Here's a quick breakdown of the stages:

Great question! CKD 3b refers to Stage 3b of Chronic Kidney Disease. CKD is a general term for a gradual loss of kidney function, and it's broken into stages based on how well the kidneys are filtering blood — measured by a score called GFR (glomerular filtration rate).
Here's a quick breakdown of the stages:
- Stage 1 – Kidney damage with normal filtering (GFR 90+)
- Stage 2 – Mild loss of function (GFR 60–89)
- Stage 3a – Mild to moderate loss (GFR 45–59)
- Stage 3b – Moderate to severe loss (GFR 30–44)
- Stage 4 – Severe loss (GFR 15–29)
- Stage 5 – Kidney failure (GFR below 15)
At Stage 3b, the kidneys are working at 30–44% of normal capacity. This is an important stage where managing things like blood pressure, diet, and fluid intake becomes especially critical to slow further decline.
It's always a good idea to work closely with a nephrologist (kidney specialist) to create a plan tailored to where things stand.
