The benefits of drinking more water and urinating more when you have a urinary tract infection are as follows: 1. Increase the volume of urine, dilute the urine and reduce the concentration of metabolic wastes in the urine. This is because the growth of bacteria within the urine is mainly dependent on these metabolic wastes. The lower the concentration of these substances, the less conducive to the growth and reproduction of bacteria. 2, more urination, can be faster to excrete the metabolic waste in the human body, to promote the body’s metabolism, so that the body’s resistance to disease increased. 3, increased urine volume, resulting in the reduction of the time between urination of patients, bacteria are not easy to grow and reproduce in the urinary tract. Of course, the prerequisites for drinking more water and urinating more must clearly exclude some diseases that require limiting the amount of water drunk, such as certain kidney diseases and certain heart diseases, as well as some diseases with unexplained generalized edema.
