What PCOS Is
Polycystic ovary syndrome is one of the most common hormone conditions in women of reproductive age. Despite the name, you don’t need cysts on your ovaries to have it.
Under the current international guideline, a diagnosis in adults generally requires two of three features, after other causes have been ruled out:
- Irregular or absent ovulation, often showing up as irregular periods
- Signs of higher androgens, such as excess facial or body hair, acne, or elevated testosterone on labs
- Polycystic ovaries on ultrasound, or a high AMH level
Diagnosis belongs with your medical provider. What happens after the diagnosis is where many women feel they’re left without a plan.
Where Insulin Fits In
Insulin resistance is common in PCOS, and it isn’t limited to women with higher body weight. When cells respond less efficiently to insulin, the body tends to make more of it.
Higher insulin can signal the ovaries to produce more androgens. That can feed the symptoms many women notice most: irregular cycles, acne, and unwanted hair growth. It also helps explain why PCOS carries a higher long-term risk of type 2 diabetes, and why regular screening matters.
Lifestyle Is First-Line Care
The 2023 international PCOS guideline recommends healthy lifestyle habits for everyone with PCOS. That isn’t a consolation prize. These habits work on the same pathways that drive many symptoms.
In practice, the focus usually includes:
- Meals built around protein, fiber, and minimally processed carbohydrates
- Regular movement, including some strength training
- Consistent sleep and realistic stress management
The guideline does not single out one “PCOS diet.” The best plan is one you can actually keep doing.
What About Supplements?
Inositol gets a lot of attention online. A review that informed the 2023 guideline found some possible metabolic benefits, but the evidence was limited, and it isn’t recommended as a replacement for other care. Supplements should be chosen carefully, with your medications and goals in view.
Where Functional Medicine Can Help
Many women with PCOS have had a few labs drawn and been handed a prescription or told to lose weight. Those may be part of the answer, but they rarely feel like a full plan.
In a virtual functional medicine consultation, we look at your cycle history, symptoms, nutrition, sleep, stress, and previous testing together. When it adds useful information, we discuss labs that reflect blood sugar regulation and hormones, and we build practical next steps you can track over time. This works alongside the care you receive from your medical provider.
The goal is a plan that makes sense for your body, not a generic handout.
