PCOS vs PCOD:
Clinical Terminology & Rotterdam Criteria
The terms "PCOD" (Polycystic Ovarian Disease) and "PCOS" (Polycystic Ovary Syndrome) are frequently confused. In international clinical guidelines, PCOS is the standard diagnostic term covering reproductive, metabolic, and hormonal manifestations. Here is an evidence-based breakdown.
International Terminology & Clinical Standards
In several regional healthcare systems (particularly in South Asia), the term PCOD is widely used to describe milder ovarian follicle changes managed primarily through lifestyle. However, major international medical bodies—including the World Health Organization (WHO), ACOG, ESHRE, and ASRM—do not define PCOD as a distinct international diagnostic code. Instead, Polycystic Ovary Syndrome (PCOS) is the single, internationally recognized medical classification.
The Rotterdam Diagnostic Criteria for PCOS
Under the International Evidence-Based PCOS Guideline, a formal diagnosis of PCOS requires meeting at least 2 out of the 3 Rotterdam criteria (after excluding adrenal disorders or thyroid-related cycle irregularity):
Ovulatory Dysfunction
Irregular, infrequent (oligo-ovulation), or completely absent menstrual periods (anovulation).
Hyperandrogenism
Clinical signs (hirsutism, severe hormonal acne, androgenic hair loss) or laboratory elevated free testosterone/androgens.
Polycystic Ovaries
Ultrasound showing 20+ small antral follicles (2–9 mm) or enlarged ovarian volume (>10 mL).
Menstrual & Reproductive Signs
- Cycles longer than 35 days or fewer than 9 cycles per year.
- Unpredictable light spotting alternating with heavy flow.
- Anovulatory subfertility requiring ovulation tracking or clinical support.
Metabolic & Androgenic Signs
- Hirsutism (excess facial, chest, or abdominal hair growth).
- Insulin resistance and compensatory hyperinsulinemia.
- Acanthosis Nigricans (velvety hyperpigmentation in skin folds).
Lifestyle & Metabolic Management for PCOS
1. Low GI Nutrition
Focus on whole grains, legumes, vegetables, and lean proteins to reduce blood glucose spikes and lower insulin levels.
2. Regular Physical Activity
Aim for 150+ minutes per week of moderate aerobic activity and progressive resistance training to enhance muscle insulin sensitivity.
3. Sleep & Stress Reduction
Prioritize 7–9 hours of sleep to regulate cortisol and support hypothalamic-pituitary-ovarian axis balance.
