Insulin resistance in PCOS: a simple guide
Insulin can influence energy, periods, weight, and long-term health in PCOS. Here’s what people mean by “insulin resistance” and small steps that help.
Why insulin matters
- Insulin helps move glucose from blood into cells. When cells respond less, the body compensates by making more insulin.
- Higher insulin can nudge androgen production and affect ovulation rhythm for some people with PCOS.
Common labs you might see
- Fasting insulin and fasting glucose — often taken together.
- HbA1c — a 2–3 month view of average blood sugar.
- Some providers calculate indices (e.g., HOMA-IR) using fasting values.
Note: Ranges depend on the lab and your clinical picture. Discuss your numbers with your clinician.
One small step to start
This week
Add a 10–15 minute post-meal walk after the meal you usually feel most sluggish. Gentle movement can improve how your body uses glucose.
Stack it gradually
- Pick one meal as your “walk meal.”
- Set a phone reminder for 10 minutes after you finish eating.
- Keep it easy: flats, casual pace, around the block.
