Painful urination during menstruation, called dysuria, occurs when period blood irritates the urethra or pelvic muscles cramp. This common issue affects about 20% of menstruating people.
The urethra runs parallel to the vagina, sharing nerve pathways. When the vaginal walls swell during periods, they press on the urethra, causing discomfort when urine passes through. Hormonal fluctuations may also increase bladder sensitivity.
| Cause | Description |
|---|---|
| Urethral irritation | Menstrual blood contains compounds that irritate the urethral lining |
| Pelvic congestion | Increased blood flow to pelvic organs during menstruation |
| Muscle tension | Cramping uterine muscles press on the bladder and urethra |
| Hormonal changes | Fluctuating estrogen levels affect urinary tract tissue sensitivity |
