Researchers at Western University and the Lawson Health Research Institute have found that increased water drinking does not slow the decline of kidney function in patients with chronic kidney disease, reports MedicalXpress.
Based on these findings, some of the researchers are suggesting that although increased water drinking does not help most patients with chronic kidney disease, it may be beneficial for those who drink lower than the recommended amount of water.
Chronic kidney disease (CKD) is the gradual decline of kidney function. Kidneys usually filter waste products from the blood and discard them in the urine, but the kidneys of patients with CKD lose the ability to do this, which can cause the build-up of fluids and waste products, and, in some cases, kidney failure. CKD often does not show any symptoms, and so is frequently diagnosed at a late stage when kidney function has already significantly declined. Patients with stage three CKD are likely to experience mild symptoms, or even none at all, but by this point, kidney function has already declined between 40 to 70%. The treatment options for CKD are limited, and care is focused on slowing the progression of the disease rather than curing it. Patients may be offered medications, salt and water guidelines, and, for those with kidney failure, dialysis and/or a kidney transplant.
