Postmenopause women can have increased chance of getting UTI because of the change in vaginal pH favour the residence of common UTI pathogen, usually E. coli. Sexually active women also have higher chance of getting this disease as pathogenice bacteria can contaminate the urethra during sexual activities.

Cloudy, bloody and foul smelling urine are also symptoms that urge a proper treatment.
