Bladder Infection Causes

Your urinary system is designed to keep out microscopic invaders. The bladder secretes a protective coating that prevents bacteria from attaching to its wall and even your urine has antibacterial properties that inhibit the growth of bacteria. But even with these defenses, certain factors increase the chances that bacteria will enter the urinary tract through the urethra, adhere to the bladder wall, and begin to multiply.

The causes for this may include:

  • Sexual intercourse
  • Escherichia coli (E.coli)
  • Prostate enlargement
  • Stones in the bladder
  • Changes in the immune system
  • Urinary catheters
  • Tuberculosis
  • Yeast infection
  • Radiation treatment to the bladder area
  • Tumors in the bladder
  • Interstitial cystitis
  • Certain medications
