For patients who have urinary tract infections, it is useful to drink more water. The more water a person takes in the more urine is discharged, so the flushing ability of the urinary tract will be greatly enhanced, and the growth of bacteria can be inhibited to some extent. However, urinary infections can’t be treated or cured by drinking water alone, but need to be treated systematically, and drinking more water is only an auxiliary measure. If you are convinced of a urinary infection, you need to go to the hospital to do a routine urine test for the nature of the white blood cells. If the patient has serious symptoms of urinary infection, has urinary frequency, urinary urgency, urinary dripping as well as urinary pain, and has two or three plus white blood cells when doing routine urine examination in the hospital, it is necessary to use quinolones or cephalosporin antibiotics for treatment under the guidance of the doctor.
