Susceptibility to UTI may be increased by any of the following factors:
- Frequent use of antibiotics, causing the normal "good" bacteria in the bladder to be negatively affected by disease-causing (pathogenic) bacteria
- Abnormality in the anomaly of the urinary tract, mainly at the level where the ureters (the tubes that connect the kidneys to the bladder) enter into the bladder
- Bowel and bladder dysfunction: this is a neurologic disturbance where the child has poor control over his bladder and bowel function
- Constipation: chronic constipation causes the bowels to become loaded with fecal matter. As a result, the bowel pushes against the bladder and causes the urine to become stagnant in it, which is a favorable place for bacteria to grow and cause infection.
