Research suggests that up to 70% of women with PCOS may have insulin resistance. Many of them are unaware, partly because a standard fasting glucose test may not capture the full picture, and results can appear within normal range even when insulin levels are elevated.
This article is for educational purposes only and is not a substitute for medical advice. If you recognize any of these signs in yourself, we encourage you to speak with a qualified healthcare provider who can run appropriate testing and give you personalized guidance.
Here are seven commonly reported experiences among women with PCOS that may be worth discussing with your doctor.
What Is Insulin Resistance?
Insulin is the hormone your pancreas releases to move sugar from your bloodstream into your cells for energy. When your cells stop responding to insulin properly — a condition called insulin resistance — your pancreas compensates by producing more and more insulin.
Chronically high insulin is the root driver behind many of the most frustrating PCOS symptoms: stubborn weight gain, high androgens, irregular cycles, and inflammation. Addressing insulin resistance is often the most important lever in PCOS management.
7 Signs You May Have Insulin Resistance with PCOS
Sign 01
Stubborn Weight Gain, Especially Around the Belly
Elevated insulin is associated with fat storage, particularly in the abdominal area. Some women with PCOS notice that weight tends to concentrate around the midsection, or that it is difficult to lose despite consistent effort. This is a common experience worth discussing with a healthcare provider, as it can have hormonal roots.
Sign 02
Energy Crashes After Meals
Feeling tired, foggy, or sluggish after eating, particularly after carbohydrate-heavy meals, is something many women with PCOS report. This may be related to how the body is processing blood sugar, though only proper testing can determine what is happening for you individually. If this sounds familiar, it is worth raising with your doctor.
Sign 03
Intense Carb and Sugar Cravings
Strong cravings for sugar and refined carbohydrates are commonly reported among women with PCOS. Some research connects this to how the body signals energy needs when blood sugar regulation is disrupted. This is not a character flaw and may have a physiological basis worth exploring.
Sign 04
Difficulty Losing Weight Despite Eating Well
Many women with PCOS describe eating carefully and still struggling to lose weight. Hormonal factors, including elevated insulin, may play a role in how the body responds to dietary changes. This is a real and frustrating experience, and it is not simply a matter of willpower. A healthcare provider can help identify what may be contributing.
Sign 05
Skin Tags or Darkened Skin Patches
A skin condition called acanthosis nigricans, which involves darkening of the skin in areas like the neck, armpits, or groin, is sometimes associated with metabolic changes including elevated insulin. Skin tags in similar areas are also sometimes noted. These are worth mentioning to your doctor as part of a broader conversation about metabolic health.
Sign 06
Irregular or Missing Periods
Elevated insulin is associated with higher androgen production, including testosterone and DHEA, which can in turn affect ovulation. Irregular cycles, missed periods, and anovulation are common in PCOS and may have multiple contributing factors. A healthcare provider can help identify what is driving cycle irregularity for you specifically.
Sign 07
Facial Hair, Acne, and Hair Thinning
Chin and jaw hair, acne along the jawline, and thinning hair on the scalp are often associated with elevated androgen levels in women with PCOS. Research suggests that insulin may play a role in androgen production for some women. These symptoms can have multiple causes and a proper evaluation can help clarify what is driving them in your situation.
Why Standard Testing May Not Tell the Full Story
Standard blood work typically includes fasting glucose and HbA1c to assess blood sugar health. These markers can be valuable, but some practitioners who specialize in functional medicine also look at fasting insulin alongside glucose, which may provide additional context about how the body is responding.
Lab interpretation is nuanced and should always be done by a qualified healthcare provider who can evaluate your full picture, not just individual numbers in isolation.
"Asking the right questions and getting comprehensive testing is often the first step to understanding what is actually going on."
What to Do If You Recognize These Signs
If several of these experiences resonate with you, the most important step is to speak with a qualified healthcare provider. Bring up your concerns, ask about comprehensive metabolic testing, and seek out a practitioner who is familiar with PCOS if your current provider is dismissing your symptoms.
A functional approach to PCOS often includes working on blood sugar stability through nutrition and movement, and may involve targeted supplementation based on individual lab findings. Any supplement use should be discussed with and supervised by a healthcare provider, as individual needs vary significantly.
The goal is to understand what is actually driving your specific situation before making decisions, rather than guessing and hoping something sticks.
