PCOS, Performance, and Your Body: What You Really Need to Know
Polycystic Ovarian Syndrome (PCOS) is one of the most common hormonal diagnoses in women of reproductive age! You might hear about it in a doctor’s office, on social media, or from a friend who’s struggling with cycles, skin, or fertility.
PCOS is seen as a kind of “umbrella” label. That means many people with very different signs, symptoms, and lab profiles all get grouped under the same name. Some may struggle with irregular periods and acne, others with blood sugar issues and weight changes, others with fertility—and some with all of the above!
Latest estimates suggest that PCOS affects around 11–13% of women, with some sources extending that up to 15–20% of women of reproductive age. Around 70% of women with PCOS are thought to be undiagnosed! So if you feel like “everyone” you know either has PCOS or wonders if they do, you’re not imagining it!
What PCOS Actually Is (and Isn’t)
PCOS is described as a diagnosed hormonal disorder that often involves a mix of:
Irregular or absent menstrual cycles
Higher androgens (often called “male hormones”) that can show up as acne or hair changes
Metabolic issues like insulin resistance, cholesterol changes, or shifts in body weight
Ovaries that may or may not look “polycystic” on ultrasound
Fertility struggles or early pregnancy loss in some cases
The key idea: PCOS isn’t just an “ovary problem!” It’s a systems problem- reflects how your metabolism, stress hormones, gut, and brain–ovary connection are all interacting over time!
In conventional medicine, diagnosis often uses what are called the Rotterdam criteria. To get the PCOS “label”, you usually need 2 out of 3:
Ovulatory dysfunction (irregular, long, or missing cycles)
Hyperandrogenism (signs like acne or excess hair, or high androgens on lab work)
Polycystic-appearing ovaries on ultrasound
Doctors may also look at things like insulin resistance, blood sugar, LH:FSH ratio, and testosterone levels.
This checklist is useful, but a functional health approach goes further and asks: what’s actually driving those changes?
How is your body handling insulin and blood sugar?
Is stress high, especially later in the day, and what does cortisol look like?
Are gut issues or inflammation showing up?
What’s the balance between estrogen, progesterone, and androgens?
From this angle, PCOS often comes with patterns like insulin resistance, low progesterone relative to estrogen, higher-than-ideal androgens, stress hormone changes, and gut imbalances!
The message is not “this is your fate.” It’s: “this is a pattern your body is running right now—and there are meaningful ways to support the systems involved.”
PCOS, Gut Health, and Immune Health
PCOS often overlaps with gut and immune issues. A common pattern looks like this:
Changes in gut bacteria (dysbiosis)
A more “leaky” gut barrier
Inflammatory molecules slipping into the bloodstream
A chronic, low-grade inflammatory state
That ongoing inflammation can worsen insulin resistance and androgen issues, feeding back into the PCOS picture. It also helps explain why PCOS is often seen alongside autoimmune and immune-related conditions, including thyroid autoimmunity!
The core theme here: when gut, metabolic, and hormone systems are under stress for a long time, the immune system can be affected too.
PCOS, Stress, and Sleep
Stress and sleep are not “side issues” with PCOS—they’re central!
Many people with PCOS show some degree of HPA axis dysregulation. (This was me!) Translation: the stress response system can get stuck in a higher or more chaotic gear. Cortisol may be elevated or poorly timed, often higher in the evening.
You might feel:
“Tired but wired” at night
More cravings and late-night hunger
Slower recovery from daily life or exercise
Brain fog and mood changes
On top of that, PCOS is associated with a much higher risk of sleep apnea in women. That can lead to fragmented sleep, daytime fatigue, and a harder time managing insulin and appetite.
Stress and sleep are not luxuries you get when everything else is perfect!! They’re major levers that influence how PCOS shows up in your body.
Movement, Food, and Daily Habits: Why They Really Matter!
Two big variables keep coming up: energy and stress!
PCOS physiology often sits at the center of:
Altered energy handling (blood sugar, insulin resistance, metabolic adaptations)
Elevated or dysregulated stress responses (HPA axis, cortisol, sleep loss)
The good news: your daily habits can positively influence both!!
Supportive movement (including strength work, walking, and other forms you enjoy) can improve how your body uses glucose and supports healthier insulin sensitivity over time. More muscle mass can translate to better metabolic flexibility and more efficient use of fuel. Muscle is a glucose sink! The more muscle you have, the more insulin sensitive you will be.
Food patterns that support blood sugar—like centering meals around protein, pairing carbs with protein and fats, and avoiding long stretches of under-eating followed by chaotic overeating—can help stabilize energy, cravings, and mood. (This was a big needle mover for me).
Simple but consistent stress and sleep practices—wind-down routines, morning light, boundaries with your phone or work at night, and treating sleep like a true priority—feed directly into hormones, blood sugar, and appetite regulation.
None of this is about perfection or following a rigid protocol. It’s about steadily creating an environment where your body feels safer and more supported, so those PCOS‑type patterns have a chance to shift!
Supplementation
On top of nutrition, movement, sleep, and stress work, starting with the Core 4 supplement foundation is a must (regardless of PCOS, everyone can benefit from taking these!) A high‑quality multivitamin to cover broad micronutrient gaps, vitamin D combined with K1 and K2 to support hormone balance, bone health, and insulin sensitivity, a concentrated omega‑3 fish oil for systemic inflammation and metabolic health, and magnesium in the evening to support insulin sensitivity, stress resilience, and sleep quality. For PCOS specifically, then layering in a few targeted supports depending on the root drivers. When insulin resistance is present, berberine‑based formulas and myo‑inositol are often used to improve glucose handling and ovarian function. Curcumin or other anti‑inflammatory support may be added when inflammation and oxidative stress are key features. Across all of this, using supplements to backfill micronutrient and metabolic needs—not as a replacement for medical care or as a stand‑alone “cure” for PCOS!!
When “Regulating My Period” Was Just a Band‑Aid: My Story
When I was first told I had PCOS, the experience didn’t feel deep or individualized. There was no ultrasound, no real digging into why my cycle was off, no honest conversation about my stress, my food, or how I was living.
I was quickly handed a prescription for birth control to “regulate my period.”
But I knew that wasn’t the real answer! Regular bleeds felt like proof that everything was fixed. But what I later learned is that birth control doesn’t actually solve the underlying reason a cycle is irregular. It’s more like putting a band‑aid over a warning light on your car’s dashboard. The bleed you see on most hormonal birth control is a withdrawal bleed, not a true, healthy ovulatory period!
There’s such a strong emphasis on how the brain and ovaries normally communicate. In a healthy cycle, the brain sends carefully timed signals so an egg matures and ovulation happens. Many forms of birth control work by dialing down or shutting off that signal, so ovulation doesn’t occur.
On paper, that can make your cycles look “regular.” In reality, it’s a medically controlled pattern—not your body running its own rhythm!
For me, the long‑term cost wasn’t just about hormones; it was about lost information and lost time. Without real ovulation and true cycles, I lost one of my body’s most powerful feedback systems. I couldn’t actually see how my hormones, stress, or metabolism were doing—because the data was being covered up.
Underneath the surface, my real issues were still there. I was under‑fueling compared to how hard I was pushing myself. I was overtraining my system with stress (in and out of the gym) and under‑recovering. From the outside, it was easy for irregular cycles and other symptoms to be labeled as “PCOS” and left at that.
Being told I might need medical help to conceive one day hit me hard. It planted this quiet belief that my body was fundamentally broken, that I was somehow defective. That belief followed me for years.
Everything began to shift when I finally zoomed out and looked at my whole system:
I started eating more consistently and intentionally, instead of trying to “earn” my food.
I approached movement with respect for recovery instead of just pushing harder.
I cut back on stress where I could and set real boundaries around work and my time, I started enjoying my life! Giving my body nurture to feel safe.
I treated sleep like a core part of my health, not an afterthought.
It didn’t change overnight, but slowly my body responded. My cycle began to normalize!! I had more stable energy, fewer crashes, and felt more at home in my own body. And the thing I was once told might require intervention?
I am writing this while my 6 month old baby naps next to me.
That doesn’t mean this will be everyone’s path, or that there’s a guaranteed outcome if you just “do everything right.” What it does show is the theme in real life: your physiology is adaptable! When you support your body with enough energy, appropriate movement, quality sleep, and better stress management, your systems can shift in powerful ways!
PCOS, RED‑S, and Why Labels Can Be Confusing
Another important point: not everyone with irregular cycles and fatigue truly has PCOS physiology! Some people are primarily dealing with relative energy deficiency (often called RED‑S), which is an evolved understanding of the female athlete triad.
RED‑S can look like:
Undereating relative to how much you’re doing (in workouts, work, and life)
Irregular or missing cycles
Hormonal changes that can resemble PCOS on the surface
So you can have two people with similar symptoms—low energy, disrupted cycles, maybe some hormonal changes—and one might have true PCOS physiology (like insulin resistance and higher androgens), while the other is mainly under‑fueled, over‑stressed, and under‑recovered.
Why does this matter? Because the most helpful next steps can be very different!
For one person, supporting blood sugar and insulin, sleep, and stress may be the primary focus. For another, the big shift might be eating more, training less intensely (at least for a season), and giving the body enough resources to feel safe again!
This is where a more nuanced approach becomes so important. The goal is to ask better questions:
Am I getting enough energy for what I’m asking my body to do?
Am I sleeping enough and well enough?
How is stress showing up in my life and in my body?
Are there patterns with blood sugar, gut health, or hormones that deserve a closer look?
Your Body Is Not Broken!
Wherever you are—newly diagnosed, questioning if you might have PCOS, coming off birth control, or trying to untangle years of confusing symptoms— my message to you is this-:
Your body is not broken- it is adapting!
PCOS is not a character flaw or a personal failure. It’s a reflection of how your systems have been responding to your internal and external environment over time.
Your job is not to “perfect” yourself. Your job is to slowly build an environment, through daily choices, that makes it easier for your body to do what it’s designed to do: heal, adapt, and move toward balance when it’s given the chance!
If you’re navigating PCOS, struggling with your cycle (or your cycle after coming off birth control), or just feeling confused about your hormones, you don’t have to figure it out alone. I offer 1:1 support grounded in the FNMS framework to help you understand what’s going on in your body and create a clear, realistic plan forward.
