What are urinary tract infection symptoms and signs?

Lower urinary tract infection

Upper urinary tract infection (pyelonephritis)

Symptoms develop rapidly and may or may not include the symptoms for a lower urinary tract infection.

  • Fairly high fever (higher than 101 F)
  • Shaking chills
  • Nausea
  • Vomiting
  • Flank pain: pain in the back or side, usually on only one side at about waist level

In newborns, infants, children, and elderly people, the classic symptoms of a urinary tract infection may not be present. Other symptoms may indicate a urinary tract infection.

  • Newborns: fever or hypothermia (low temperature), poor feeding, jaundice
  • Infants: vomiting, diarrhea, fever, poor feeding, not thriving
  • Children: irritability, eating poorly, unexplained fever that doesn't go away, loss of bowel control, loose bowels, change in urination pattern
  • Elderly people: fever or hypothermia, poor appetite, lethargy, change in mental status

Pregnant women are at increased risk for an UTI. Typically, pregnant women do not have unusual or unique symptoms. If a woman is pregnant, her urine should be checked during prenatal visits because an unrecognized infection can cause pregnancy complications.

Although most people have symptoms with a urinary tract infection, some do not.

The symptoms of urinary tract infection can resemble those of sexually transmitted diseases.
