Urinary Tract Infection (UTI), Adult

Understanding UTI

A urinary tract infection (UTI) is an infection of any part of the urinary tract. The urinary tract includes:

  • The kidneys.
  • The ureters.
  • The bladder.
  • The urethra.

These organs make, store, and get rid of pee (urine) in the body.


What Are The Causes?

This is caused by germs (bacteria) in your genital area. These germs grow and cause swelling (inflammation) of your urinary tract.

What Increases The Risk?

You are more likely to develop this condition if:

  • You have a small, thin tube (catheter) to drain pee.
  • You cannot control when you pee or poop (incontinence).
  • You are female, and:

You use methods to prevent pregnancy:
-A medicine that kills sperm (spermicide).
-A device that blocks sperm (diaphragm).
-You have low levels of a female hormone (estrogen).
-You are pregnant.

  • You have genes that add to your risk.
  • You are sexually active.
  • You take antibiotic medicines.
  • You have trouble peeing because of:

-A prostate that is bigger than normal, if you are male.
-A blockage in the part of your body that drains pee from the bladder (urethra).

-A nerve condition that affects your bladder (neurogenic bladder).
-Not getting enough to drink.
-Not peeing often enough.

  • You have other conditions, such as:

-Diabetes
