Acute cystitis is most often caused by bacteria. Bacteria enter the urethra and travel into the bladder. The urethra is a tube that allows urine to pass from the bladder to the outside. Bacteria may come from the lower intestines, the rectal area, or skin.
Factors that increase your risk of uncomplicated cystitis include:
- History of acute cystitis
- Sexual activity
Birth control—Use of diaphragm or
coated with spermicide
Factors that increase your risk of complicated cystitis include:
- Having a urinary catheter
- History of childhood urinary tract infection
- Compromised immune system
Abnormalities of urinary system, such as
- Enlarged prostate
- Catheter use
- Birth control devices—Use of diaphragm or with spermicide
Symptoms may include:
- Frequent and urgent need to urinate
- Passing only small amounts of urine
- Pain in your abdomen, pelvic area, or lower back
- Burning sensation during urination
- Leaking urine
- Increased need to get up at night to urinate
- Cloudy, bad-smelling urine
- Blood in your urine
- Low-grade fever
The doctor will ask about your symptoms and medical history. A physical exam will be done. Urine will be tested for the presence of bacteria.
Acute cystitis is common in women. Children and men who develop acute cystitis may require additional examination of the bladder.
Acute cystitis is treated with antibiotics. It is important to take all antibiotics as recommended. Finish all your antibiotics even if you are feeling better.
Your doctor may also prescribe medication to reduce pain and bladder spasms.
Here are some steps you can take to keep bacteria out of your urinary tract:
- Drink plenty of liquids.
- Include cranberry juice in your diet. Some studies support the use of cranberry juice to prevent urinary tract infections.
- Urinate when you have the urge. Do not resist it.
- After sexual intercourse, empty your bladder.
- Wash genitals daily.
- If you're a woman, always wipe from the front to the back after having a bowel movement.
- Avoid using douches and feminine hygiene sprays.
- Avoid wearing tight underwear or clothing.
