Patients with urinary incontinence generally need a daily water intake of about 1000 to 2000 milliliters. Although those suffering from urinary incontinence may involuntarily excrete urine from the urethra, their water intake needs to be the same as that of normal individuals. Drinking more water is beneficial for the body, as it increases urine production, which can dilute the concentration of stone-forming substances in the urine, thus reducing the likelihood of developing urinary stones. Increased urine production due to higher water intake can promptly flush the urinary tract, especially washing away bacteria on the urethra, thereby reducing the chances of urinary tract infections. Furthermore, drinking more water increases urine production and promptly excretes metabolic waste products produced in the body through the urine, thus preventing the accumulation of metabolic products.
