EpistemisProgressive secondary dysmenorrhea
Specialty: Gynecology and breast.
Why it occurs
- Pelvic endometriosis (peritoneal or ovarian)
- Adenomyosis (presence of ectopic endometrial tissue in the myometrium)
- Uterine fibroids (especially large submucosal or intramural fibroids)
- Acquired cervical stenosis (post-conization or uterine procedures)
- Copper intrauterine device (IUD)
- Chronic pelvic inflammatory disease
Initial workup
Detailed gynecological transvaginal ultrasound with color Doppler (first-line tool to diagnose adenomyosis, fibroids and endometriomas). Pelvic MRI for precise mapping of diffuse adenomyosis or deep endometriosis. Hysterosalpingography or hysteroscopy if cervical stenosis or endocavity pathology is suspected. Diagnostic/therapeutic laparoscopy (reference standard for peritoneal endometriosis).
red flags
Pain completely refractory to optimal doses of NSAIDs and combined hormonal contraceptives, persistent pelvic pain that becomes chronic outside the menstrual period (non-cyclical pelvic pain), severe deep dyspareunia, associated infertility, fever or foul-smelling vaginal discharge.
Standard management
- Naproxen 500 mg orally every 12 hours or Mefenamic acid 500 mg every 8 hours, scheduled 24-48 hours before menstrual flow
- Combined contraceptives (oral, patches or vaginal ring) in a continuous regimen
- Levonorgestrel intrauterine release system (IUD-Mirena 52 mg) of choice for adenomyosis and associated menorrhagia
- Dienogest 2 mg/day orally continuously (note: hormonal treatments seek atrophy of ectopic endometrial tissue and induction of amenorrhea to control pain).
