Frequently asked questions
Why do my urine infections keep coming back?
Sometimes because the original infection was never fully cleared, sometimes because the organism was resistant to the antibiotic used, and often because something is making recurrence more likely: menopausal changes, incomplete bladder emptying, or prolapse. Culture and examination separate these.
I keep being given antibiotics. Is that a problem?
Repeated empirical courses select for resistant organisms and disturb the vaginal flora, which can itself cause symptoms. That does not mean antibiotics are wrong, but it does mean the diagnosis should be confirmed rather than assumed each time.
Could it be the menopause rather than infection?
Frequently, yes. Falling oestrogen thins the tissue around the urethra and bladder, producing urgency, frequency and burning that are indistinguishable from cystitis. Local vaginal oestrogen reduces recurrent urinary symptoms substantially in postmenopausal women.
Does cranberry or D-mannose work?
The evidence for cranberry is weak and inconsistent, and it is not a treatment for an active infection. D-mannose has some supportive data but is not established. Neither is a substitute for finding out why the infections recur.
When do I need to see a urologist?
Visible blood in the urine, loin pain with fever, repeated culture-proven infections, or symptoms that do not respond to appropriate treatment. Those warrant urological assessment, and it is arranged rather than left with you.
What should I bring?
A list of the antibiotics you have taken, including anything bought or prescribed abroad, and any previous urine results if you have them. Ideally do not start a new antibiotic in the days before the appointment, so a sample can be cultured.
