Research-informed care for the whole experience of PMOS.

PMOS is more than one symptom

PMOS can look different from one person to another. Some people seek care for irregular or absent cycles; others are most concerned about acne, unwanted hair growth, hair loss, fertility, insulin resistance, fatigue, mood or longer-term health.

Assessment should consider the pattern as a whole. Medical diagnosis and exclusion of other causes remain important, particularly when periods are very infrequent, symptoms change quickly or pregnancy is being planned.

What we may work on

• Understanding cycle patterns, symptoms, pathology results and previous treatment
• Nutrition and movement that support metabolic and reproductive health without using body weight as a proxy for health
• Sleep, stress, energy and the practical demands of everyday life
• Evidence, limitations and safety of supplements or herbal medicines
• Fertility and preconception priorities, where relevant
• A plan that is realistic, reviewable and suited to your preferences

Why my research matters in the consultation

My PhD examined the effectiveness and safety of natural supplements and other complementary medicines for PMOS, then called PCOS. That work informs how I interpret evidence, discuss uncertainty and consider whether an intervention is likely to be useful for the individual in front of me.

Research informs the options; it does not make the decision for you. Your priorities, previous experiences, medical care and capacity to implement a plan remain central.

Research findings: herbal medicine and lifestyle care

My randomised controlled trial involved 122 participants with PCOS, now called PMOS, and compared a specific herbal formulation plus lifestyle care with lifestyle care alone. Combined care produced greater improvements in menstrual regularity over three months. Participants and clinicians knew which treatment was received, and longer-term research is needed. The findings do not apply to every herbal product or individual.

How might herbal medicines work?

My 2014 review brought together laboratory studies and clinical findings on selected herbal extracts. It identified potential effects on hormones involved in ovulation, including luteinising hormone (LH) and follicle-stimulating hormone (FSH), as well as testosterone and insulin. Effects differed between herbs, and the clinical evidence varied in quality. Understanding a possible mechanism helps explain a treatment choice, but does not establish that it will work for a particular person.

Nutritional supplements and inositol

My 2017 systematic review assessed 24 trials involving 1,406 participants. It found promising results for some supplements, alongside important gaps in study quality and safety reporting.

Inositol is involved in insulin signalling — how cells respond to the hormone that helps regulate blood glucose. The review found improvements in fasting glucose, insulin and some reproductive outcomes compared with controls. However, study limitations and differences between trials mean benefits are uncertain and may vary between individuals. These findings inform a discussion about suitability, rather than a recommendation for everyone.
