- Use of feminine hygiene products that contain
- Lack of
estrogen, which allows bacteria that can cause UTIs to
grow more easily in the
urethra. Women who have gone through

Risk factors in both women and men
factors apply to both women and men. These include:

- 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
