Insulin resistance in PCOS, explained
Insulin helps move glucose into cells. When cells respond less (insulin resistance), insulin rises — often tied to energy dips, cravings, and several PCOS symptoms. Context (glucose/A1c, symptoms) matters.
How insulin works
Insulin is like a key that unlocks the cell door so glucose can move inside and be used for energy.
In insulin resistance
The lock is stubborn. More insulin shows up, but the door barely opens and glucose struggles to get in.
Why insulin matters
- Higher fasting insulin can show your body is working harder to keep glucose steady.
- It can relate to acne, hair changes, weight changes, and energy dips.
- Small consistent habits move the needle more than big, irregular efforts.
How to think about numbers
Fasting insulin is reported in µIU/mL (or pmol/L). Pair with glucose/A1c and symptoms — don’t rely on a single number.
Small step that helps
Add a relaxed 10-minute walk after your largest meal. It’s simple, low-effort, and improves insulin sensitivity over time.
