Hello and welcome to JA. Dr Saleem here. Will be answering you shortly
So your GP advised you to increase your fluid intake?
I seriously doubt the logic in that as its based on common misconceptions like increasing the plasma volume would benefit the kidneys or help recover from damage already done.
Increased water intake only benefits where there is sudden onset short duration kidney damage due to insufficient kidneys perfusion such as in dehydration ( severe diarrhea, heat exhaustion, burns etc).
The underlying cause of renal derangement should be identified rather then just focusing on water intake.
Do you have any other medical conditions such as diabetes, high blood pressure , ? What was the cause ,if you had been told about it or not?
While RA in itself can lead to kidney disease ,your exact diagnosis would probably require a biopsy- taking sample out of your kidney with a needle.
Another common causes esp amongst women is recurrent uti leading to pyelonephritis which can cause chronic kidney disease.
So nothing much would change as far as these numbers are concerned just over 5 days.
It will need further evaluation with more specific tests as i mentioned that will guide us towards appropriate treatment.
I hooe your query is adequately addressed.
If there is no cause on blood and urine work or no history of diabetes, high blood pressure or recurrent uti then i am afraid biopsy would be needed.
eGFR definitely tells us about the kidney functions and a low eGFR as you have is quite significant for further work up.
Biopsy gives you definitive diagnosis. Dont need to be scared as its a short procedure, they numb the area before doing it so you wont feel anything. I would do it if you came to me.
