The PCOS guides

• What Is HOMA-IR? The Insulin Resistance Number, Explained - HOMA-IR = fasting insulin (uIU/mL) x fasting glucose (mg/dL) / 405. Below 1.9 is usually insulin sensitive; 2.5 and above commonly flags resistance.
• PCOS Blood Tests: The Labs Worth Asking About - PCOS labs usually include total and free testosterone, SHBG, DHEA-S, fasting insulin and glucose, HbA1c, lipids, AMH, TSH and prolactin. Ranges explained.
• PCOS Diet: What the Evidence Actually Supports - No single diet is proven best for PCOS. Evidence supports lower-glycemic carbs, protein at each meal, 25 to 30 g fiber daily and regular meals aimed at insulin.
• PCOS Symptoms: The Full List and Why Tracking Changes Care - PCOS affects 8 to 13 percent of women of reproductive age. The full symptom list by group, the Rotterdam criteria behind diagnosis, and what to track.
• Irregular Periods and PCOS: What Counts, What to Track - In adults, cycles under 21 or over 35 days, or fewer than 8 periods a year, count as irregular. How PCOS causes it, what else to rule out, what to track.
• AMH and PCOS: Why the Number Runs High - AMH is typically two to three times higher in PCOS due to the raised small-follicle count. What the assay measures, ranges by age, and its limits.
• The 4 Types of PCOS: Useful Lens or Internet Myth? - The 4 types of PCOS are not a medical classification. Medicine uses four Rotterdam phenotypes, A to D. What each popular label points at, and what to test.
• Insulin Resistance and PCOS: Signs, Testing, and What Helps - Insulin resistance affects most people with PCOS, lean or not. The signs, the tests that catch it early including HOMA-IR, and the levers with real evidence.
• How to Prepare for a PCOS Appointment (So It Actually Helps) - Bring 6 to 12 months of cycle dates, a symptom summary, every prior lab, your full medication list and three written questions. The full prep checklist.
