What are urinary tract infection symptoms and signs?
Lower urinary tract infection
- Bladder (cystitis): The lining of the urethra and bladder becomes inflamed and irritated.
- Dysuria: pain or burning during urination
- Frequency: more frequent urination (or waking up at night to urinate, sometimes referred to as nocturia); often with only a small amount of urine
- Urinary urgency: the sensation of having to urinate urgently
- Cloudy, bad-smelling, or bloody urine
- Lower abdominal pain or pelvic pressure
- Mild fever (less than 101 F), chills, and "just not feeling well" (malaise)
- Urethra (urethritis): Burning with urination
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
- 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.
