PCOS to PMOS: Why the Name Is Changing And How Nutrition & Lifestyle Changes Can Help

Written By Jo Douglas

Polycstic ovary syndrome (PCOS) has been renamed to polyendocrine metabolic ovarian syndrome (PMOS). This move by the Global Name Change Consortium has taken place to correct the misconception that the condition is solely a gynaecological disease that creates ovarian cysts, and instead is an endocrine and metabolic condition, affecting 1 in 8 women.

For years, many women have struggled with the term Polycystic Ovary Syndrome, as the name can feel confusing and misleading.

Despite the name, not everyone with PCOS has ovarian cysts, and the condition affects far more than just the ovaries. Other symptoms can include:

  • Irregular or absent periods

  • Weight gain

  • Hirsutism (thick, dark hair on the face, neck, chest, tummy, lower back, buttocks or thighs)

  • Thinning hair or hair loss

  • Oily skin and acne

  • Insulin resistance

  • Fertility challenges

  • Fatigue

  • Mood changes

Nutrition and lifestyle changes can play a powerful role in supporting hormone balance, blood sugar regulation and overall wellbeing.

1. Focus on Blood Sugar Balance

Blood sugar swings can worsen symptoms by increasing insulin levels, which may affect hormone production.

Helpful strategies can include:

  • Opt for foods lower on the Glycaemic Index (GI). These include whole grains, green leafy vegetables, apples, pears, berries, fish, meat, nuts, seeds and legumes.

  • Eat protein and fibre with every meal.

  • Avoiding skipping meals.

  • Limit snacking.

  • Reduce reliance on sugary snacks and refined carbohydrates.

  • Try to do some light exercise after meals. Think a gentle walk or cycle.

Balanced meals help support steadier energy, mood and hormone function.

2. Prioritise Protein

Good quality protein supports blood sugar balance, satiety, muscle health and hormone production:

  • Eggs

  • Fish

  • Dairy

  • Tofu and tempeh

  • Beans and lentils

  • Meat

  • Nuts and seeds

  • Quinoa.

Aim to include protein with every meal. Aim for 1g protein per kg of body weight daily.

3. Increase Fibre Intake

Fibre supports gut health, blood sugar regulation, hormone detoxification, fullness and appetite balance.

Fibre-rich foods include:

  • Vegetables

  • Fruits

  • Oats

  • Beans

  • Lentils

  • Chia seeds

  • Flaxseeds.

Many women are simply not eating enough fibre consistently. Aim for +30g fibre per day.

4. Support Inflammation

PCOS/PMOS is often linked with low-grade inflammation.

Anti-inflammatory foods may include:

  • Oily fish

  • Extra virgin olive oil

  • Colourful vegetables

  • Berries

  • Nuts and seeds

  • Herbs and spices such as turmeric and ginger

Highly processed and sugary foods, and excess alcohol may worsen inflammation for some people.

5. Consider Gut Health

The gut microbiome can influence hormones, inflammation, blood sugar balance and mood.

To support gut health aim to:

  • Eat a variety of plant foods

  • Eat +30g fibre daily

  • Include prebiotic and probiotic foods daily.

6. Supportive Nutrients

Certain nutrients have been founds to support insulin sensitivity for women with PCOS and therefore consider increasing foods rich in these and/or supplementation:

  • Chromium. Food sources include broccoli, green beans, potatoes, whole grains, meat, black pepper, basil and garlic.

  • Vitamin D. Sunlight exposure is the best source. Some food sources are mushrooms, eggs and oily fish.

  • Magnesium. Found in leafy green veggies, pumpkin seeds, flaxseeds, legumes, cacao, dark chocolate, bananas and whole grains.

  • Omega 3 fatty acids. Food sources include oily fish, walnuts, flaxseeds and chia seeds.

7. Lifestyle Factors

Stress hormones and poor sleep can significantly impact cravings, energy, insulin sensitivity and hormones.

Think about supportive practices that you can implement daily:

  • Gentle movement and exercise daily - think walking, cycling, yoga, swimming.

  • Have a set sleep routine - a daily bedtime and rise time, aiming for 7-9 hours. Your bedroom should be cool and dark with no distractions.

  • Manage caffeine intake - try not to drink after lunchtime to allow caffeine to clear from your body before you go to bed. There are several herbal teas which have been shown to support PCOS / PMOS symptoms, such as liquorice, spearmint, chamomile and nettle.

Do you need further support?

Whether the name remains PCOS or shifts to PMOS, one thing is becoming increasingly clear: this condition is about far more than ovaries alone.

With the right support, many women notice significant improvements in energy, symptoms and overall quality of life through sustainable nutrition and lifestyle changes.
