Done physical test. How much is GFR likely to change with more hydration?
Patient: I recently had a physical and all of my labs came back at acceptable levels accept my creatine 1.1 and GFR 55. My doctor wants to retest my kidney function and told me to hydrate well before the test. How much is my GFR likely to change with more hydration? Also, I have severe urge incontinence . When I drink too much water, I have to urinate in large quantities every 20-30 mins. Won t this effect my hydration levels? Doctor: Hi Welcome to HCM. Hydration is a prerequisite for proper kidney function and it is hard to quantify the change. Incontinence is a bladder issue and has go nothing to do with the kidney. Th basic fact is that kidneys need water to keep functioning, irrespective of how often you pass urine. Best regards DR GS
