Urinary tract infections are caused by unwelcome bacteria colonizing the urethra, bladder, ureter, or kidneys. In general, it's easier for "bad" bacteria like E. coli to access female anatomy because the urethra is so close to the anus. If cystitis (an infection of the lower urinary tract) isn't treated, the bacteria can continue their climb to the kidneys, where an infection can become far more dangerous.
To lower your risk of getting another UTI, you can do the following:
• Urinate before and after having sex
• Wipe yourself front to back after using the bathroom
• Drink lots of water
• Don't "hold it" for too long when you need to urinate
Some research has also shown the natural benefits of cranberry in keeping e. Coli from bonding to the urinary tract.
