eGFR fluctuations are actually pretty common and don't always mean your kidney function is dramatically changing. Several everyday factors can cause those numbers to shift up or down.
Here are some things that can affect your eGFR reading:
- Hydration levels — being well-hydrated or dehydrated at the time of the test can change results
- Recent diet — eating a lot of protein before a test can temporarily raise creatinine levels
- Physical activity — intense exercise can affect creatinine in your blood
- Illness or stress — both physical and emotional stress can impact how your kidneys function temporarily
- Time of day and lab differences — small variations can occur between tests Your readings (55, 62, 53, 68) are placing you around Stage 3a kidney disease, which means mild to moderate kidney damage. The fluctuation within that range is worth tracking but not necessarily alarming on its own.
The most important thing is to share this pattern with your nephrologist. They can look at the trend over time and determine whether the changes are just normal variation or something that needs attention. Consistent monitoring is key! 🙂
