Urinary tract infections (UTIs) occur when bacteria enter the urinary tract, usually through the urethra, and multiply in the bladder or other parts of the urinary system. The most common bacteria causing UTIs is Escherichia coli (E. coli), which normally lives in the gut and around the anus
. You can get a UTI in several ways:
- Bacteria from the gut or anus can enter the urethra during wiping after using the toilet, especially if wiping is done from back to front
- Sexual activity can introduce bacteria from a partner’s genitals, anus, fingers, or sex toys into the urethra
- Poor hygiene or touching the genital area with unwashed hands can transfer bacteria to the urethra
- Using certain types of birth control, like diaphragms or spermicides, can increase risk by irritating the urinary tract or affecting urine flow
- Other risk factors include having a shorter urethra (more common in women), pregnancy, menopause, urinary tract abnormalities or blockages (e.g., kidney stones, enlarged prostate), diabetes, or a weakened immune system
In summary, a UTI happens when bacteria enter the urinary tract and multiply, often facilitated by factors like sexual activity, anatomy, hygiene practices, and certain medical conditions
