What does the presence of decreased glomerular filtration rate indicate?

The presence of a decreased glomerular filtration rate (GFR) primarily indicates kidney function impairment. GFR is a measure of how effectively the kidneys are filtering blood and removing waste products. When the GFR decreases, it suggests that the kidneys are not functioning properly, which can arise from conditions such as acute kidney injury or chronic kidney disease. Monitoring GFR is crucial in assessing the health of the kidneys and determining the appropriate interventions needed to manage the underlying condition.

While liver dysfunction, heart failure, and fluid overload can impact kidney function, they do not directly relate to decreased GFR in the way that impaired kidney function does. Understanding the implications of GFR is essential for clinicians in diagnosing and treating renal-related issues effectively.
