Yes, you should be concerned if your GFR (glomerular filtration rate) is 56, as it falls below the normal range. A GFR of 56 indicates that your kidneys may not be functioning optimally and warrants further investigation.
Here's a more detailed breakdown:
-
Normal GFR: Generally, a normal GFR is considered to be 60 or higher.
-
GFR of 56: A GFR of 56 suggests that your kidneys are functioning below the normal level. According to the National Kidney Foundation, a GFR between 30 and 59 indicates Stage 3 kidney disease.
-
What to do:
- Consult your doctor immediately: It is crucial to consult your doctor for a proper diagnosis and to determine the underlying cause of the reduced GFR.
- Further testing: Your doctor may order additional tests, such as urine tests, blood pressure measurements, and imaging studies, to assess your kidney health.
- Monitor GFR: Regular monitoring of your GFR is important to track any changes in kidney function. The National Kidney Foundation recommends getting your eGFR checked regularly if you are at risk for kidney disease.
- Underlying conditions: Reduced GFR can be caused by various factors, including diabetes, high blood pressure, heart disease, and certain medications.
-
Why it matters: A consistently low GFR can indicate chronic kidney disease (CKD), which, if left untreated, can progress and lead to kidney failure.
-
Important Note: While a single GFR reading of 56 warrants concern, your doctor will consider other factors, such as your age, sex, race, and overall health, to make an accurate assessment. If your eGFR is less than 60 for three months or more, it is a strong indicator that your kidneys may not be working well.
In summary, a GFR of 56 is below the normal range and suggests possible kidney dysfunction. It's crucial to consult your doctor for further evaluation and management to protect your kidney health.
