If volume depletion is severe, GFR falls, but it has been thought to be completely reversible with hydration, unless ischemia results in acute kidney injury (AKI). Nevertheless, AKI is thought be largely reversible. Hence, dehydration has not been classically considered a risk factor for chronic kidney disease (CKD).
How much water should you drink to improve kidney function?

Healthcare providers may tell you not to eat or drink anything, except water, after midnight. You may also be asked not to eat any cooked meat the night before the test. It can increase the level of creatinine in your blood and affect your GFR results.
Is a GFR of 52 bad?
A GFR of 60 or higher is in the normal range. A GFR below 60 may mean kidney disease. A GFR of 15 or lower may mean kidney failure.
Does fasting affect GFR results?
Conclusions: In fasting adults, high hydration lowered GFR and increased natriuresis. After a meat meal, GFR increased only in the high hydration regimen and natriuresis only in the low hydration regimen. Hydration affects GFR and natriuresis under fasting conditions and after a meat meal.
Is coffee bad for kidneys?
In summary, coffee is an acceptable beverage for kidney disease. If consumed in moderation it poses little risk for those with kidney disease. Additives to coffee such as milk and many creamers increase the potassium and phosphorus content of coffee.
What is a normal GFR for a 70 year old?
Following the classical way, we can assert that normal GFR values are largely over 60 mL/min/1.73 m2 in healthy subjects, at least before the age of 70 years. However, we know that GFR physiologically decreases with age, and in adults older than 70 years, values below 60 mL/min/1.73 m2 could be considered normal.
What can I drink to improve my kidney function?

Why would my GFR drop suddenly?
A decrease or decline in the GFR implies progression of underlying kidney disease or the occurrence of a superimposed insult to the kidneys. This is most commonly due to problems such as dehydration and volume loss.
Can low GFR make you tired?
A severe decrease in kidney function can lead to a buildup of toxins and impurities in the blood. This can cause people to feel tired, weak and can make it hard to concentrate.
What does GFR of 50 mean?
eGFR is an estimate of kidney filtration
As normal eGFR is round about 100, the eGFR gives you an approximate ‘percentage function’. So if your eGFR is 50, your kidneys are probably filtering at about 50% of normal.
