Symptoms of Urinary Tract Infection (UTI)
Most people with a UTI will have symptoms such as:
- Passing urine more often
- Passing only small amounts of urine at a time
- Feeling like they need to pass urine right away
- Problems waiting to pass urine during the day or at night
- Burning or pain when passing urine
- Genital itching
- Pain in the lower belly, lower back, or along the sides under the ribs
- Blood in the urine—women may have blood on toilet paper after passing urine and wiping
- Cloudy urine—may also have pus
- Urine with a strange smell
An infection that has gone into the kidneys may also cause:
- Fever or chills
- Severe pain in the lower back
Children and babies may have less common problems, such as:
- Feeding problems
- Not being able to wait to pass urine
- Nausea or vomiting
- Slow weight loss and growth—failure to thrive
Older people may have problems like tiredness, confusion, loss of appetite, or trouble walking.
