What causes painful urination in women?
Experiencing pain during urination—medically termed dysuria—is a common symptom in women and can arise from several underlying causes. The most frequent cause is a urinary tract infection (UTI), particularly cystitis, which involves bacterial inflammation of the bladder lining. Escherichia coli accounts for the majority of these infections, and symptoms often include burning or stinging during urination, increased urinary frequency, urgency, and sometimes suprapubic discomfort or cloudy/foul-smelling urine.
Other infectious causes include urethritis (inflammation of the urethra), often associated with sexually transmitted infections such as chlamydia or gonorrhea, especially in younger, sexually active women. Vaginal infections—like candidiasis (yeast infection), bacterial vaginosis, or trichomoniasis—can also irritate the periurethral tissues and mimic or contribute to dysuria. In postmenopausal women, genitourinary syndrome of menopause (GSM), formerly known as atrophic vaginitis, may lead to urethral and vaginal mucosal thinning, dryness, and inflammation, resulting in painful urination.
Non-infectious contributors include chemical irritants (e.g., scented soaps, douches, spermicides), foreign bodies (such as retained tampons), urolithiasis (urinary stones), interstitial cystitis/bladder pain syndrome, and, less commonly, pelvic floor muscle dysfunction or neoplastic conditions. A thorough evaluation—including detailed history, physical examination, and targeted testing (e.g., urinalysis, urine culture, STI screening, or vaginal pH/wet mount)—is essential to identify the precise etiology and guide appropriate management.
