Also called: UTI

The urinary system consists of the kidneys, ureters, bladder and urethra. Infections of the urinary tract (UTIs) are the second most common type of infection in the body. You may have a UTI if you notice

  • Pain or burning when you use the bathroom
  • Fever, tiredness or shakiness
  • An urge to use the bathroom often
  • Pressure in your lower belly
  • Urine that smells bad or looks cloudy or reddish
  • Less frequently, nausea or back pain

If you think you have a UTI, it is important to see your doctor. Your doctor can tell if you have a UTI by testing a sample of your urine. Treatment with medicines to kill the infection will make it better, often in one or two days.
