dehydration can cause your creatinine levels to temporarily go up
when you creatinine levels go up, this causes your estimated or eGFR levels to go down since your eGFR is estimated with your age, sex, race and creatinine levels.
eGFR is not the same as a true GFR which is only obtained by a 24 hour urine collection.
once your nausea and dehydration is better and you are drinking more water and fluids, your creatinine levels will go back down and your eGFR will go back up.
you don't have to worry.
I bet your creatinine levels are normal now and your eGFR levels are normal now.
and you don't have kidney disease.
you don't have to worry about CKD
just keep drinking water and fluids and your kidneys will be fine
