more recently, patients have been asking about â and nephrologists have been recommending â increased water intake to keep kidney disease away. for years, a growing number of nephrologists and primary care physicians have been recommending drinking more water to either dilute unrecognized nephrotoxins or just bathe the kidneys in a friendly environment. about 4 years ago, researchers from canada performed the decently sized but underpowered ckd wit randomized clinical trial to determine whether increased water intake would slow the rate of kidney decline. although a major limitation was a possible lack of adherence to increased water intake (most patients had an increased urine output by only 600 ml/d), ckd wit was my first scientific exposure to the notion that water wasn’t as kidney-protective as once thought. nonetheless, organizations remain focused on the renal benefits of increasing water intake. to help resolve this issue, investigators of the ckd-rein study undertook a 3-year prospective trial of 1265 patients with stage 3 or worse chronic kidney disease to determine which, if any, amount of water intake would reduce decline in kidney function.
individuals who drank the least or most amount of water daily (< 0.5 or > 2.0 l/d, respectively) had the greatest likelihood of experiencing kidney decline (hazard ratio, 1.92 and 2.43, respectively) compared with those who had moderate water intake (1.0-1.5 l/d). all of this means that we should no longer be focused on the amount of water one drinks. ckd wit and ckd-rein have called into question the belief that we can simply bathe the kidneys with water and all will be well. moderate water consumption is all we can recommend on the basis of the available science. he is the founder of nod analytics, a free social media analytics group that serves the medical education community. staff nephrologist, department of veterans affairs, charlotte, north carolina; associate professor, virginia college of osteopathic medicine, blacksburg, virginiadisclosure: tejas p. desai, md, has disclosed the following relevant financial relationships:serve(d) as a director, officer, partner, employee, advisor, consultant, or trustee for: american association of kidney patientsreceived research grant from: national comprehensive cancer networkcreator of: nephrology on-demand
the .gov means it’s official. the site is secure. background: optimal daily water intake to prevent chronic kidney disease (ckd) progression is unknown. taking the kidney’s urine-concentrating ability into account, we studied the relation of kidney outcomes in patients with ckd to total and plain water intake and urine volume.
results: patients’ median daily intake was 2.0 l [interquartile range (iqr) 1.6-2.6] for total water and 1.5 l (1-1.7) for plain water, median urine volume was 1.9 l/24 h (iqr 1.6-2.4) and mean euosm was 374 ± 104 mosm/l. neither total water intake nor urine volume was associated with either kidney outcome. high plain water intake was also significantly associated with faster egfr decline. conclusions: in patients with ckd, the relation between plain water intake and progression to kidney failure appears to be u-shaped.
ckd wit and ckd-rein have called into question the belief that we can simply bathe the kidneys with water and all will be well. just as an apple in patients with ckd, the relation between plain water intake and progression to kidney failure appears to be u-shaped. the national kidney foundation recommends people with stages i and ii chronic kidney disease (ckd) to consume 8 glasses of water per day and, .
whilst all fluid counts towards your fluid intake, water is one of the healthiest choices when it comes to maintaining kidney health. sip water little and often. women should aim to drink eight 200ml glasses of fluid a day. men should aim to drink ten 200ml glasses of fluid a day. drinking enough water also helps produce more urine, which helps to flush out infection-causing bacteria. beware of pills and procedures. drinking extra water with certain medications or before and after procedures with contrast dye may help prevent kidney damage. as the effective therapy for preventing kidney stones, increased water intake clears sodium, urea, and osmoles. guidelines recommend increasing water intake to patients with ckd should not “push fluids.” normal thirst-guided intake should determine water intake, unless there is a specific reason to increase fluid “while many claims about the benefits of increased water intake remain untested, a growing body of evidence suggests that increased water intake, .
