Bladder Infections that Keep Coming Back
A urinary tract infection (UTI) is one of the most common infections in women. Most of the time, a short course of antibiotics clears it up. But for some women, UTIs keep returning three or more times in a year. This is called recurrent UTI, and it needs a different approach than treating each infection separately.
Recurrent UTIs are not just uncomfortable they affect sleep, work, relationships, and overall quality of life. And repeated antibiotic use over time raises concerns about antibiotic resistance.
Why do some women get recurrent UTIs?
- Anatomy — women have a shorter urethra, making it easier for bacteria to reach the bladder
- Menopause — falling oestrogen levels cause the vaginal and urethral tissues to thin (vaginal atrophy), making infections more likely
- Incomplete bladder emptying — urine that stays in the bladder for too long allows bacteria to grow
- Sexual activity — bacteria can be introduced into the urethra during intercourse
- Use of certain contraceptive methods
- Cystocele — a prolapsed bladder that does not drain fully
How does Dr. Saradha approach recurrent UTIs?
Rather than treating each infection in isolation, Dr. N.S. Saradha investigates the underlying cause. A full assessment includes urine culture, a bladder scan to check for residual urine, and a detailed clinical evaluation.
Treatment is then personalised:
- Vaginal oestrogen — for post-menopausal women, local oestrogen restores the protective tissue environment and significantly reduces recurrences
- Preventive low-dose antibiotics — a small daily dose taken for several months breaks the cycle of recurrent infection
- Post-coital antibiotics — a single dose taken after intercourse, if that is the trigger
- D-Mannose and cranberry supplements — evidence-based supplements that reduce bacterial sticking to the bladder wall
- Behavioural advice — guidance on hydration, hygiene, bladder habits, and safe sexual practices
- Treating underlying conditions — addressing prolapse or incomplete bladder emptying if that is contributing
Recurrent UTI can be stopped. It needs proper investigation and a consistent plan not just repeated antibiotics.
