According to a new research, consuming water does not help in slowing down the effects of kidney disease for a chronic kidney disease (CKD) patient.
For the study, the team recruited 630 people with Stage 3 CKD, causes of which were different including diabetes and blood pressure. They arranged randomized clinical trials with patients at various hospitals and determined whether coaching patients to drink more water slowed their decline in kidney function over a year as compared to those in the control group, who were coached to maintain usual fluid intake.
“Despite widespread beliefs, little scientific data exists on the optimal amount of water to drink,” explained Dr William Clark. “While many claims about the benefits of increased water intake remain untested, a growing body of evidence suggests that increased water intake improves kidney function through the suppression of the antidiuretic hormone.”
Researcher Kerri Gallo said, “Kidney disease can range from mild to severe and, in some cases, leads to kidney failure. Kidney disease often starts slowly and develops without symptoms over a number of years, so it may not be detected until it has progressed to the point where kidney function is quite low.”
The researchers found that after a year, the increase of water did not show any decrease in the loss of kidney function. They found that an increase of water did significantly suppress their antidiuretic hormone release, particularly when the patients’ intake was low.
The study was published in the Journal of the American Medical Association.
