Rotterdam PCOS Consensus Criteria Check
2 of 3 Criteria Met
Clinical consensus requires at least 2 out of 3 features after excluding thyroid dysfunction, hyperprolactinemia, or non-classical CAH:
1. Ovulatory Dysfunction / Oligomenorrhea:
Present (2-3 periods in 5 months off pill).
2. Hyperandrogenism (Clinical or Biochemical):
Present (Jawline breakouts, chin/facial hair darkening, thigh hair changes).
3. Polycystic Ovarian Morphology (Ultrasound / AMH):
Unverified (Requires pelvic ultrasound: ≥20 follicles/ovary or increased ovarian volume >10ml).
Differential Red Flags Detected:
Substantial unexplained weight loss (-2 stone) and daily chronic abdominal pain are NOT standard post-pill withdrawal or typical PCOS features. They warrant prioritized gastroenterological / comprehensive medical evaluation to exclude IBD, celiac disease, or chronic pelvic pain etiology.
Recommended Evidence-Based Action Items
- Track basal body temperature or ovulation strips if trying to verify cycle resumption
- Log duration and exact characteristics of facial and body hair changes
- Discuss persistent weight loss and abdominal pain separately with a physician
- Schedule hormone panel (total/free testosterone, DHEAS, LH/FSH) after month 6 if cycles remain irregular
Primary diagnostic benchmark: 2023 International Evidence-based Guideline for PCOS & Rotterdam Consensus Criteria. Hormonal birth control suppresses LH/FSH and masks pre-existing oligomenorrhea for the duration of therapy.
