Understanding PCOS: a functional approach to hormone balance

Polycystic Ovary Syndrome (PCOS) is often spoken about as a hormone condition, but in reality, it runs much deeper than that. It’s a complex condition that affects both hormones and metabolism, and it’s thought to impact up to 1 in 8 women in the UK.

It can show up in many different ways. For some, it’s irregular or missing periods. For others, it’s weight gain that feels difficult to shift, persistent acne, excess hair growth, or struggles with fertility. Many women also experience low mood, anxiety, or a sense that their body feels out of sync.

If you’re living with PCOS, you may feel like your body is working against you. This is something I see often in clinic, and it can feel incredibly frustrating and confusing.

While the name focuses on the ovaries, the root drivers of PCOS are often much broader, involving a combination of blood sugar imbalance, hormone disruption, inflammation, and lifestyle factors.

What’s really going on in PCOS?

Although PCOS presents differently for everyone, there are a few common underlying patterns.

One of the most significant is insulin resistance. This is where the body becomes less responsive to insulin, the hormone that helps regulate blood sugar. To compensate, the body produces more insulin.

Over time, higher insulin levels can disrupt ovulation and stimulate the ovaries to produce more testosterone. This can contribute to symptoms such as acne, excess hair growth, and irregular cycles.

Another common feature is higher levels of androgens (often referred to as male hormones). While women naturally produce these hormones, elevated levels can impact skin, hair, and ovulation.

Many women with PCOS also experience low-grade inflammation, which can further disrupt hormone balance and metabolic health.

This is why PCOS is not just a fertility condition. If left unsupported, it can increase the risk of longer-term health concerns such as type 2 diabetes and cardiovascular disease.

Why symptoms can look so different

One of the reasons PCOS can feel so confusing is that no two people experience it in exactly the same way.

Some women may have insulin resistance as the main driver, while others may be more impacted by stress, inflammation, or coming off hormonal contraception. Weight is not always a defining factor – many women with PCOS are in a healthy weight range but still experience symptoms.

This is where a more personalised approach becomes important. Rather than focusing on the label alone, it’s about understanding what’s driving your symptoms and supporting your body accordingly.

The role of nutrition and lifestyle

The good news is that nutrition and lifestyle changes can have a powerful impact on PCOS. Rather than focusing on restriction or extreme approaches, the aim is to support the body in a way that feels sustainable and nourishing. Small, consistent shifts can help to rebalance blood sugar, support hormone production, and reduce inflammation over time.

Five supportive strategies for PCOS

1. Balance blood sugar at every meal

Building meals that include protein, fibre, and healthy fats can help slow the release of glucose into the bloodstream. This supports more stable energy and reduces the demand for insulin. Choosing whole, minimally processed carbohydrates such as quinoa, oats, sweet potato, and fruit can also make a noticeable difference.

2. Increase fibre intake

Fibre plays an important role in both blood sugar balance and hormone health. It helps to slow digestion and can support the body in clearing excess hormones. Vegetables, legumes, flaxseeds, chia seeds, and whole fruits are all great sources to include regularly.

3. Focus on anti-inflammatory foods

Including a wide variety of colourful plant foods, along with healthy fats such as olive oil, nuts, seeds, and oily fish, can help to reduce inflammation in the body. This doesn’t need to be complicated – often it’s about adding more of the foods that support you, rather than focusing on what to remove.

4. Support healthy fats

Fats are essential for hormone production. Omega-3 fats, found in foods like salmon, walnuts, and flaxseed, may be particularly supportive for regulating cycles and supporting overall hormone balance.

 5. Create consistency with meals

Regular, balanced meals can help stabilise blood sugar and support hormone rhythms. Skipping meals or grazing throughout the day can sometimes make symptoms feel worse. For many women, starting the day with a nourishing breakfast can be a helpful place to begin.

A more holistic way to approach PCOS

PCOS is a complex condition, but it is not something you are powerless over. By looking beyond symptoms and focusing on the underlying drivers, such as blood sugar balance, inflammation, and lifestyle, it’s possible to support your body in a more sustainable and empowering way.

There is no one-size-fits-all approach, which is why personalised support can be so valuable. Understanding your own patterns and working with your body, rather than against it, is often where the most meaningful changes happen.

If you’ve been feeling frustrated or stuck with your symptoms, you’re not alone. PCOS can feel overwhelming, but with the right support and a clear, realistic approach, things can begin to shift.

Small changes, done consistently, can have a powerful impact over time, not just on symptoms, but on how you feel in your body as a whole.
