Every day, the kidneys filter around 120 – 150 quarts (4800 – 6000 ounces) of fluid, said Medical News Today.
The health site added: “Of these, approximately one to two quarts (40 – 80 ounces) are removed from the body in the form of urine, and the rest is recovered by the bloodstream.
“Water is essential for the kidneys to function and if the kidneys do not function properly, waste products and excess fluid can build up inside the body.
“Untreated, chronic kidney disease can lead to kidney failure with the organs not working, and either dialysis or kidney transplantation is required.
“Urinary tract infections are the second most common type of infection in the body.
“If infections spread to the upper urinary tract, including the kidneys, permanent damage can result. Sudden, or acute, kidney infections can be life-threatening, particularly if septicaemia occurs.
Drinking plenty of water is a simple way to reduce the risk of developing a serious infection.”
