Urinary Tract Infections in Teens and Adults
What Increases Your Risk
Risk factors in women
Urinary tract infections (UTIs) are most common in young to middle-aged sexually
women. Things that increase a woman's risk of getting
- Sexual activity, which pushes bacteria into
the urethra. Sexual activity with the use of a diaphragm and spermicide raises
- Lack of
estrogen, which allows bacteria that can cause UTIs to
grow more easily in the
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:
- Problems with the
prostate gland . Men become increasingly prone to UTIs
as they get older because of prostate problems, such as enlarged prostate
(benign prostatic hyperplasia) and
- An uncircumcised
- Anal intercourse.
- Unprotected sex with a woman
who has a vaginal infection.
- HIV infection.
Risk factors in both women and men
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
- 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
