Both men and women are at risk for getting a UTI, underlying risk factors can include:
- Blockages in the urinary tract. Kidney stones or an enlarged prostate in men, can trap urine in the bladder and create an ideal environment for bacteria to grow.
- Having a compromised immune system. Diabetes, autoimmune diseases or chronic illnesses that suppress the immune system can affect the body's ability to defend against bacteria. Taking medication that may impair the immune system can also increase your risk of infection.
Women are also more likely than men to develop a UTI, mainly due to differences between the male and female anatomy. In general, women get UTIs up to 30 times more often than men do.1
Here are a few factors contributing to women's higher susceptibility to UTIs:
- The female urethra is nearly 4x shorter than of the male urethra. The female urethra is much shorter and located close to the anus and vagina, making it easier for bacteria to travel from the urethra to the bladder.
- Exposure to bacteria during intercourse. During sexual activity the female urethra will be introduced to bacteria. It is important to always empty your bladder after sex to help flush out the bacteria.
- Different methods of birth control.Certain methods of birth control like a diaphragm can increase bacteria growth or using unlubricated or spermicidal jelly could irritate the urethra. Try using a water-soluble lubricant.
- After menopause, there is a decrease in estrogen production which can make the urinary tract more vulnerable to infection.
