Insulin resistance, explained without the jargon
It's the quiet engine behind so much of PMOS (PCOS) — and once you understand it, "just eat less" stops being the answer.
Insulin resistance gets thrown around in PMOS (PCOS) circles like everyone already knows what it means. Most people don't, because it's usually explained in textbook language. Here's the version that actually helps.
Start with what insulin does
When you eat, carbohydrates become glucose — sugar — in your blood. Insulin is the hormone that knocks on your cells' doors and says, "open up, take this glucose in for energy." In a body that's running smoothly, a little insulin gets a lot done.
With insulin resistance, the cells stop answering the door as easily. So your pancreas does the only thing it can: it sends more insulin. Blood sugar may still look normal on a basic test, because all that extra insulin is keeping it in line behind the scenes. That's why insulin resistance can go unnoticed for years — the standard glucose check looks fine while insulin itself is quietly running high.
Your labs can look "normal" while insulin runs high behind the scenes. That's why so many women are told nothing's wrong.
Why that makes weight feel "stuck"
High insulin is, among other things, a fat-storage signal. When it's chronically elevated, your body is biased toward holding on to fat and away from releasing it — no matter how disciplined you are. This is the part that's so maddening for women with PMOS (PCOS): the effort is real, the willpower is real, and the scale still won't move, because the hormonal setting underneath is working against you.
It's also why so many women are handed "eat less, move more" and walk away feeling like a failure. The advice isn't wrong, exactly — it's just aimed at the wrong floor of the building.
The PMOS (PCOS) feedback loop
In PMOS (PCOS), high insulin doesn't stop at fat storage. It also pushes the ovaries to make more androgens — the hormones linked to irregular or missing periods, acne, and excess hair growth. Those symptoms, the weight, and the insulin all feed one another. Lower the insulin pressure and you often ease the whole loop, not just one symptom. That's the logic behind treatments — including GLP-1 medications — that improve how the body responds to insulin.
What this means when you compare providers
If insulin resistance is the engine, then a provider who never looks under the hood is missing the point. This is why our Care Standard rewards providers who treat PMOS (PCOS) as a metabolic condition and titrate care to how you respond — and why we're skeptical of flat, one-dose-fits-all models that treat every patient identically.
Plain questions to bring to an appointment
- Will you check my insulin or HbA1c, not just my glucose?
- If I'm insulin resistant, how does that change my plan?
- How will my dose adjust over time based on my response?
- What lifestyle changes give the most return for insulin resistance specifically?
You don't need to become a clinician. You just need enough of the picture to recognize when someone is treating the symptom and ignoring the cause — and to choose a provider who isn't.
