What Increases Your Risk

Risk factors in women

Urinary tract infections (UTIs) are most common in young to middle-aged sexually active women. Things that increase a woman's risk of getting UTIs include:

  • Sexual activity, which pushes bacteria into the urethra. Sexual activity with the use of a diaphragm and spermicide raises the risk.
  • Pregnancy.
  • Previous UTIs.
  • Lack of estrogen, which allows bacteria that can cause UTIs to grow more easily in the vagina or urethra. Women who have gone through menopause are at increased risk for UTIs.

Risk factors in men

Things that increase a man's risk of UTIs include:

Risk factors in both women and men

Certain risk factors apply to both women and men. These include:

  • Having a catheter in place. Bacteria can enter the catheter and start an infection. Most at risk are older adults who are in hospitals or who live in long-term care facilities.
  • Kidney stones and other obstructions in the urinary tract. These may block the flow of urine, raising the risk of bacterial infection.
  • Diabetes. People with diabetes are at greater risk for UTIs because their immune systems are weakened. Also, long-term high blood sugar can damage the kidneys' filtering system (diabetic nephropathy).
  • Structural problems of the urinary tract. These may be present at birth or develop later in life.
