Bladder infection

Bladder infection (urocystitis) is a very common infectious disease.


Bladder infection (urocystitis) is a very common infectious disease. Pathogens, mostly intestinal bacteria, spread to the bladder, which is usually filled with germ-free (sterile) urine, and cause an infection. Typical symptoms include an increased urge to urinate and difficulty in passing urine, and sometimes burning and pain during urination. Preventive measures include, for example, warmth, intimate hygiene and an increased intake of fluid.


  • Difficulty in passing urine, sometimes burning and pain during urination
  • Frequent need to urinate (also during the night)
  • Dribbling, small amounts of urine
  • Urine may be cloudy, reddish brown (if it contains blood) and foul-smelling
  • Uncontrolled urine leakage
  • Dull, cramping pains in the bladder area


  • Increasingly severe pain in the lower abdomen, back and sides
  • Fever or chills
  • Growing discomfort and nausea
  • Chronification, i.e. recurrent bladder infections (at least 2 to 3 times a year)
  • Pyelitis
  • Sepsis (urosepsis)

Risk factors:

Further treatment by your doctor / in hospital

Possible tests:
  • Chemical and microscopic urine test
  • Urine culture (search for bacteria)
  • Blood test, if necessary
  • In particular for complex cases: ultrasound, bladder endoscopy

  • Antibiotics
  • Surgery for mechanical obstructions such as constrictions, urinary stones, tumours

What can I do myself?

Preventive measures:
  • Avoid hypothermia
  • Intimate hygiene: wipe from front to back, don’t use vaginal douches and vaginal deodorants
  • Urinate immediately after intercourse
  • Make sure to completely empty the bladder
  • Drink more fluids
    • Drink > 2 litres of unsweetened fluid per day
    • If a heart or kidney disease has been diagnosed, only after consultation with a doctor
When symptoms start, also:
  • Cranberry extract or juice: supports the bladder mucosa and has an anti-inflammatory effect
  • Heating pad or hot water bottle (to relax the bladder and pelvis)
  • Common painkillers such as ibuprofen and paracetamol (read the package insert)

When to see a doctor?

  • No noticeable improvement with household remedies within two days
  • Fever, back or flank pain in the area of the kidneys
