Falling kidney function
Function is usually lost silently, so the trend on a blood test matters more than any single reading.
What it may mean
Kidney function is usually lost gradually and silently. By the time symptoms appear, a great deal of function has already gone, which is why the trend on a blood test matters more than any single reading.
A declining eGFR is worth assessing properly rather than repeating in six months. The purpose of the assessment is to find and treat any reversible cause, slow the rate of decline where that is possible, and understand what is driving it.
What happens next
- Review of the creatinine and eGFR trend over time
- Urine protein quantification and kidney ultrasound
- Blood pressure and medication review
- Assessment for any reversible or obstructive cause
Kidney failure & transplant assessment
When kidney function falls far enough to need dialysis or a transplant, the decision is about timing as much as technique.
If this is happening now
Complete inability to pass urine, visible blood in the urine, or severe one-sided flank pain with fever need same-day assessment. Attend your nearest emergency department.
