Bladder Infection Risk Factors

Risk factors for bladder infection include:

Elderly men have increased risk of bladder infection because they commonly have benign prostatic hypertrophy. The enlarged prostate places pressure on the urethra, which reduces urine flow and increases the risk of infection.

Elderly women have an increased risk of bladder infection because the muscles in the lower abdomen weaken. This increases the risk that bacteria enter the urethra and spread to the bladder.
