PCOS: What New Research Says About Supporting Hormones and Metabolism

PCOS Is A Whole-Body Condition

PCOS is traditionally associated with the ovaries, but scientists now understand that several biological systems interact in the condition.

Three core processes are involved:

• Elevated androgens (often called “male-type” hormones)
• Insulin resistance and metabolic disruption
• Irregular ovulation and ovarian dysfunction

These systems influence one another.

For example, elevated insulin levels can stimulate the ovaries to produce more androgens, which can then interfere with ovulation.

This hormonal and metabolic interaction helps explain many common symptoms of PCOS, including:

• Irregular menstrual cycles
• Acne
• Excess facial or body hair
• Hair thinning on the scalp
• Difficulty ovulating
• Weight gain or difficulty losing weight

Because several systems are involved, PCOS is now considered a lifelong metabolic and endocrine condition, not simply an ovarian disorder.

Inflammation And Metabolism Play A Key Role

One of the most important areas of research in PCOS today is the role of chronic low-grade inflammation.

Fat tissue can release inflammatory signalling molecules that influence hormone regulation and insulin sensitivity.

These inflammatory signals may:

• Worsen insulin resistance
• Increase androgen production in the ovaries
• Disrupt normal follicle development

Researchers are also exploring the role of the gut microbiome, as changes in gut bacteria may influence inflammation and metabolic health.

This growing body of research highlights why strategies that support metabolic health and reduce inflammation are often central to PCOS management.

Lifestyle Support Remains The Foundation Of PCOS Care

Across international medical guidelines, lifestyle support is consistently recommended as the first-line approach for PCOS management.

This includes:

• Balanced nutrition
• Regular physical activity
• Healthy body composition
• Long-term metabolic support

Importantly, the research does not support one single “perfect” diet for PCOS.

Instead, sustainable nutrition strategies tailored to the individual are encouraged.

The guidelines recommend aiming for:

• 150–300 minutes of moderate activity per week
or
• 75–150 minutes of vigorous activity

along with resistance training.

Even modest improvements in metabolic health can positively influence insulin signalling, hormone balance, and ovulation.

Nutritional And Nutraceutical Support May Play A Role

Because insulin resistance, inflammation, and metabolic disruption are central to PCOS, many supportive strategies focus on these systems.

The medical review highlights inositol as a commonly used nutritional compound in PCOS.

Inositol acts as an intracellular signalling molecule involved in:

• Insulin signalling
• Glucose metabolism
• Ovarian follicle development

Some studies suggest it may improve metabolic markers in women with PCOS, although clinical improvements in symptoms such as hirsutism or weight appear more modest.

Researchers also note that because PCOS involves inflammation, oxidative stress, and metabolic dysregulation, broader nutritional and dietary approaches that support these systems may be beneficial.

This may include strategies that support:

• Stable blood sugar regulation
• Anti-inflammatory dietary patterns
• Gut health and microbiome balance

These areas remain active fields of research as scientists continue to explore how nutritional interventions may support the underlying biology of PCOS.

Environmental Factors May Also Influence PCOS

Scientists increasingly believe that environmental exposures may influence how PCOS develops.

Research suggests that certain environmental factors may affect gene expression through processes known as epigenetic changes.

Some of the factors currently being studied include:

• Dietary patterns
• Sedentary lifestyle
• Exposure to endocrine-disrupting chemicals
• Environmental pollutants

These influences may affect hormone signalling, metabolism, and ovarian function.

While this research is still developing, it reinforces the idea that PCOS is influenced by both genetic predisposition and environmental factors.

Pharmaceutical Treatments

While lifestyle support forms the foundation of care, medications may be used when additional support is needed.

For example:

Hormonal contraceptives
These are commonly used to regulate menstrual cycles and reduce androgen-related symptoms such as acne or excess hair growth.

Anti-androgen medications
Medications such as spironolactone may be used when symptoms related to androgen excess remain significant.

Metabolic medications
Metformin has historically been used to improve insulin resistance, although newer evidence suggests its effects may be more limited than previously believed.

Newer metabolic therapies
Medications known as GLP-1 receptor agonists are increasingly being studied for PCOS and may help improve metabolic health and insulin resistance in some women.

These medications typically target specific symptoms, but they are usually used alongside lifestyle and metabolic support strategies rather than replacing them.

PCOS Affects Health Beyond The Reproductive Years

Another important insight from modern research is that PCOS affects health throughout life.

Women with PCOS have increased risk of several metabolic and health conditions, including:

• Insulin resistance
• Type 2 diabetes
• Metabolic syndrome
• Sleep apnea
• Anxiety and depression

Importantly, these risks can occur even in women with PCOS who are not overweight.

For this reason, ongoing monitoring of metabolic health is recommended regardless of body size.

Why A Whole-Body Approach Matters

Because PCOS affects multiple systems in the body, long-term care often works best when it addresses several areas at once.

This may include support for:

• Hormonal balance
• Metabolic health
• Inflammation
• Nutritional status
• Mental wellbeing

5 Core Strategies you should know to support your PCOS

Research now recognises that PCOS involves a complex interaction between hormones, metabolism, inflammation, and insulin signalling. Because of this, management strategies often work best when they support several biological systems at the same time.

While medications may be used in some cases, international guidelines consistently emphasise that lifestyle and metabolic support remain the foundation of PCOS management.

Based on the current research, five practical strategies are often highlighted.

1. Prioritise Blood Sugar Stability

Insulin resistance plays a central role in many cases of PCOS. Elevated insulin levels can stimulate the ovaries to produce more androgens, which may contribute to symptoms such as acne, excess hair growth, and disrupted ovulation.

Dietary patterns that support stable blood sugar levels may help reduce this signalling. This often includes:

• Eating balanced meals that include protein, fibre, and healthy fats
• Reducing large spikes in refined carbohydrates and sugars
• Supporting steady energy levels across the day

Even modest improvements in insulin sensitivity can positively influence hormonal regulation.

2. Support Metabolic Health Through Movement

Physical activity improves insulin sensitivity and metabolic health, which can indirectly support hormone balance in PCOS.

International guidelines recommend aiming for:

• 150–300 minutes of moderate activity per week
or
• 75–150 minutes of vigorous activity

Including resistance training can also support muscle mass and glucose regulation.

Importantly, movement does not need to be extreme to be beneficial. Consistent, sustainable activity appears to be the most important factor.

3. Focus On Anti-Inflammatory Nutrition

Many women with PCOS show signs of chronic low-grade inflammation.

Dietary patterns rich in whole foods may help support inflammatory balance and metabolic health.

This often includes emphasising:

• Vegetables and fibre-rich foods
• Healthy fats such as olive oil, nuts, and seeds
• Minimally processed foods

These dietary patterns are associated with improved metabolic markers and may support long-term health in PCOS.

4. Consider Targeted Nutraceutical Support

Some nutritional compounds are being studied for their potential role in supporting metabolic and hormonal pathways involved in PCOS.

One of the most commonly researched is inositol, a compound that supports insulin signalling and ovarian function (pssst - you can find this in our Cycle Regulate + Ovulate & CycleBloom 40:1)

Research suggests inositol may support:

• Insulin sensitivity
• Ovulation in some women
• Metabolic markers related to glucose regulation

While results vary between studies, nutraceuticals that support metabolic and inflammatory pathways remain an active area of PCOS research.

5. Take A Long-Term Whole-Body Approach

Because PCOS affects several biological systems, effective management often involves supporting the body as a whole rather than focusing on one symptom alone.

This may include strategies that support:

• Hormonal balance
• Metabolic health
• Gut health
• Sleep and stress regulation

Long-term care is particularly important because PCOS is associated with increased risk of metabolic conditions such as insulin resistance and type 2 diabetes later in life.
