Exploring PMOS through Western medicine, Ayurveda and Yoga Therapy to better understand your diagnosis, the underlying processes and your options for making informed decisions about your health.

Receiving a PCOS/PMOS diagnosis can leave you with more questions than answers. You may be aware of the hormonal imbalances, irregular menstrual cycles or metabolic changes associated with the condition, but not fully understand why they occur, how they influence your overall health or what treatment options are available to support you.

Polycystic Ovary Syndrome (PCOS), now also referred to as Polyendocrine Metabolic Ovarian Syndrome (PMOS), is commonly associated with irregular menstruation, ovarian follicles and hormonal imbalances, it is a complex condition that can also affect metabolism, insulin sensitivity, reproductive function and psychological wellbeing.

Learning about these processes can help you ask better questions, recognise patterns in your own health and participate more confidently in decisions about your health care.

In this article, we'll explore PMOS through contemporary Western medicine and the traditional principles of Ayurveda. We'll also examine how Yoga Therapy may support women living with the condition, and what current medical research tells us about different treatment approaches.

This article is intended for education and understanding, not medical diagnosis or individual treatment advice. Its purpose is to help you become more informed about your health and the treatment possibilities you may wish to explore with appropriately qualified healthcare professionals.

From PCOS to PMOS: Why the Name Has Changed

In May 2026, an international initiative announced the renaming of Polycystic Ovary Syndrome (PCOS) to Polyendocrine Metabolic Ovarian Syndrome (PMOS). The change reflects a broader understanding of the condition and the limitations of its original name.

For decades, the term polycystic directed attention towards the ovaries and the presence of what were commonly described as cysts. However, these structures are generally small ovarian follicles rather than true cysts, and not every woman with the condition has this ovarian appearance. More importantly, the original name failed to capture the wider hormonal and metabolic disturbances that characterise the condition.

The proposed terminology describes three important aspects:

• Polyendocrine: Involving multiple hormones and the systems that regulate them.

• Metabolic: Affecting how the body processes, stores and uses energy, including blood glucose and insulin regulation.

• Ovarian: Recognising that ovarian and reproductive function may also be affected.

This change is significant because PMOS is not simply a condition affecting menstruation or fertility. Its effects can extend throughout a woman's life, influencing metabolic function, cardiovascular risk and psychological wellbeing. The name change does not itself alter the condition or establish new diagnostic criteria. PCOS remains widely used in clinical guidelines, research and healthcare settings. For clarity, this article uses PMOS while recognising that most existing research refers to PCOS.

PMOS from a Western Medical Perspective

PMOS is a complex endocrine and metabolic condition affecting approximately 10–13% of women of reproductive age. It involves disturbances in ovarian function, androgen regulation and, frequently, insulin metabolism. These processes can influence one another, contributing to irregular ovulation, menstrual changes and metabolic difficulties.

Understanding Androgen Hormones

Androgens are a group of hormones that include testosterone. Although often described as male hormones, androgens are naturally present in both men and women. In women, they are produced primarily by the ovaries and adrenal glands, which sit above the kidneys. Androgens contribute to sexual function, hair growth and other important physiological processes.

In PMOS, the body may produce more androgens than usual, or their activity may be increased. This is known as hyperandrogenism. Elevated androgen activity can contribute to acne, increased facial or body hair, thinning hair on the scalp and disturbances in ovulation. Insulin also plays a role. When insulin levels become elevated, they can stimulate the ovaries to produce more androgens, potentially contributing to further hormonal imbalance.

This is one reason PMOS is understood as a condition involving both reproductive hormones and metabolic health.

Common Hormonal Changes

The following hormones may be involved in PMOS, although their levels and activity can vary considerably between individuals.

Hormone	What it does and what may happen in PMOS
Testosterone	May be higher than normal, contributing to acne, facial hair growth and thinning scalp hair.
Insulin	Helps move sugar from the blood into cells for energy. The body may need to produce more insulin when cells become less responsive to it.
Luteinising hormone (LH)	Helps trigger ovulation. Its signalling may become altered, contributing to increased androgen production.
Follicle-stimulating hormone (FSH)	Helps eggs develop within the ovaries. Egg development may become disrupted, even when FSH levels are normal.
Progesterone	Rises after ovulation and helps regulate the menstrual cycle. Levels may remain low when ovulation does not occur.
Oestrogen	Supports the menstrual cycle and reproductive health. Levels may fluctuate differently when ovulation is irregular.
Sex hormone-binding globulin (SHBG)	A protein that binds to hormones such as testosterone. When SHBG is low, more testosterone remains available to act on the body.
Anti-Müllerian hormone (AMH)	Reflects the number of small developing follicles in the ovaries. Levels are often higher in women with PMOS.

Not every woman with PMOS will experience the same hormonal changes. Hormone levels may also vary depending on age, menstrual cycle, medication use and individual physiology.

Common Signs and Symptoms

PMOS can manifest differently from one woman to another. Some experience significant menstrual irregularity and fertility difficulties, while others have relatively regular cycles but experience androgen-related or metabolic symptoms.

Common presentations include:

• Menstrual and reproductive: Irregular or absent periods, unpredictable bleeding, infrequent ovulation and difficulty conceiving.

• Skin and hair: Acne, oily skin, increased facial or body hair and thinning hair on the scalp.

• Metabolic: Insulin resistance, increased abdominal fat, difficulty managing weight, altered cholesterol levels and increased risk of type 2 diabetes.

• Psychological: Increased prevalence of anxiety, depressive symptoms, body-image concerns and reduced quality of life.

• Other associated concerns: Sleep disturbances, obstructive sleep apnoea in some individuals and increased risk of endometrial thickening when ovulation is persistently absent.

PMOS also occurs in women who are lean and physically active. Excess body weight is not required for diagnosis, and the absence of weight-related symptoms does not exclude metabolic concerns.

How Is PMOS Diagnosed?

The 2023 International Evidence-based Guideline for PCOS recommends that, in adults, diagnosis may be made when at least two of the following three features are present, after excluding other possible causes:

1. Clinical or biochemical signs of elevated androgen activity.

2. Irregular ovulation or menstrual cycles.

3. Polycystic ovarian morphology on ultrasound, or appropriately assessed AMH as an alternative in adults.

When irregular menstrual cycles and hyperandrogenism are both present, ultrasound is not necessary for diagnosis. Different criteria apply to adolescents, for whom ultrasound and AMH are not recommended as diagnostic criteria.

Other Conditions That May Produce Similar Symptoms

Because PMOS shares symptoms with several other hormonal conditions, medical assessment may include investigating other possible causes.

Thyroid dysfunction: The thyroid gland helps regulate metabolism, energy and many other physiological functions. An underactive or overactive thyroid can affect menstrual regularity, weight, energy levels and reproductive function, producing symptoms that may overlap with PMOS.

Hyperprolactinaemia: This occurs when the body produces too much prolactin, a hormone primarily involved in breast milk production. Elevated prolactin can interfere with ovulation and cause irregular or absent menstruation. In some cases, it may also cause unexpected breast milk production.

Non-classic congenital adrenal hyperplasia (NCCAH): This is an inherited condition affecting hormone production in the adrenal glands. It can cause increased androgen production, leading to symptoms such as acne, unwanted facial hair, irregular menstruation and fertility difficulties.

These conditions are not forms of PMOS, but they can produce similar symptoms. Identifying the underlying cause is important because the most appropriate treatment may differ.

Etiology: What Causes PMOS?

The exact cause of PMOS is not yet fully understood. Current research suggests that it develops through interactions between genetic susceptibility, hormonal signalling, insulin resistance and environmental influences.

One of the key factors contributing to PMOS is insulin resistance. When cells become less responsive to insulin, the pancreas compensates by producing more of it. Elevated insulin can stimulate ovarian androgen production and reduce the amount of SHBG produced by the liver, increasing the availability of circulating testosterone. This may interfere with normal follicular development and ovulation, contributing to irregular menstrual cycles.

Excess body fat can intensify insulin resistance and hormonal disturbances, but it is neither necessary nor sufficient to cause PMOS. Genetic and developmental factors may influence susceptibility, while sleep, physical activity, nutrition and other environmental factors can influence how the condition manifests.

Chronic stress can also influence the hormonal and metabolic processes involved in PMOS. Chronic psychological stress may affect sleep, eating behaviours, autonomic regulation and metabolic health. However, stress has not been established as a primary cause of PMOS.

Understanding these contributing factors is useful because it demonstrates why treatment may need to address more than reproductive symptoms alone.

The Ayurvedic Perspective on PMOS

Classical Ayurvedic texts do not describe PMOS as a distinct disease corresponding exactly to the modern medical diagnosis. However, several classical conditions and pathological processes share characteristics with PMOS, particularly those involving menstruation, reproductive function, metabolic disturbance and tissue accumulation.

Rather than trying to identify PMOS with one Ayurvedic disorder, a more useful approach is to assess the individual's Dosha, Agni, Dhatu, Srotas and Samprapti.

Understanding PMOS Through Dosha

PMOS is frequently interpreted in contemporary Ayurveda as a Kapha–Vata disorder, although Pitta may also play a role.

Kapha is associated with structure, stability, nourishment and accumulation. In a presentation characterised by increased adiposity, metabolic sluggishness and tissue accumulation, Kapha may be considered predominant.

Vata, particularly Apana Vata, governs downward-moving physiological functions, including menstruation and reproductive processes within the traditional Ayurvedic framework. Irregular menstruation, delayed cycles and disturbances in reproductive function may therefore be interpreted as Apana Vata dysfunction.

Pitta may be implicated where inflammatory skin conditions, acne, increased heat or other Pitta-associated qualities are prominent. However, these symptoms should be considered within the individual's complete presentation rather than automatically assigned to one Dosha.

These associations are general Ayurvedic interpretations, not direct equivalents of specific hormonal changes.

Agni, Ama and Metabolic Function

In Ayurveda, Agni governs how we digest food, absorb nutrients and transform them into energy and nourishment for the body's tissues. When Agni becomes disturbed, the appropriate digestion and transformation of nutrients and tissues may also become compromised.

In a Kapha-dominant PMOS presentation, an Ayurvedic practitioner might identify Mandagni, or diminished digestive capacity, accompanied by signs interpreted as Ama accumulation. This may be considered alongside disturbances in Medo Dhatu, the tissue associated with adipose and lipid functions, and Rasa Dhatu, which is concerned with the primary nourishment and distribution of nutrients throughout the body.

When Agni becomes impaired, food and nutrients may not be properly digested and transformed. This can lead to the formation of Ama, which is understood as incompletely processed material that can accumulate within the body, obstruct the Srotas (channels) and interfere with healthy tissue nourishment and function.

Dhatu and Srotas Involvement

Several Ayurvedic structures may be considered during assessment:

Ayurvedic principle	Relevance to a PMOS presentation
Rasa Dhatu	Nourishment, tissue formation and the relationship between nutrition and reproductive health.
Rakta Dhatu	Blood-related and Pitta-associated manifestations.
Medo Dhatu	Adipose tissue, accumulation and metabolic patterns.
Artava	Menstrual and reproductive function.
Medovaha Srotas	Channels associated with fat metabolism and nourishment.
Artavavaha Srotas	Channels associated with female reproductive function.
Apana Vata	Traditional regulation of menstruation and reproductive processes.

These principles provide a framework for understanding how disturbances in nourishment, metabolism and reproductive function may be connected within Ayurvedic theory.

Samprapti: Understanding the Development of Disease

Samprapti describes the development and progression of disease according to Ayurvedic pathology. Rather than focusing exclusively on symptoms, it considers how disturbances arise, circulate, localise and eventually manifest. The classical six stages of disease development, known as Shat Kriya Kala, provide a useful framework for understanding this progression.

The following is an illustrative Ayurvedic interpretation of a Kapha–Vata PMOS presentation. Please note It is not a classical PMOS-specific Samprapti or a scientifically established explanation of how the condition develops.

Stage 1: Sanchaya (Accumulation)

Kapha begins to accumulate in response to factors traditionally considered Kapha-promoting, such as inactivity, excessive heavy foods or disturbed digestive function. Subtle changes in appetite, energy or tissue nourishment may be noticed.

Stage 2: Prakopa (Aggravation)

The accumulated Dosha becomes aggravated. An Ayurvedic assessment might identify increasingly disturbed Agni, heaviness, lethargy or signs of altered tissue metabolism.

Stage 3: Prasara (Spreading)

The aggravated Dosha is understood to spread beyond its primary site, affecting other tissues and channels. Kapha and Ama may be considered to interfere with normal tissue nourishment, while Vata regulation becomes disturbed.

Stage 4: Sthana Samshraya (Localisation)

In Ayurveda, this is the stage where an imbalance begins to affect a particular part of the body. In the case of PMOS, this may involve the Artavavaha Srotas (the channels associated with menstruation and reproductive function). The accumulation of Kapha and Ama is believed to obstruct the normal functioning of these channels, known as Srotorodha. This can disturb Apana Vata, the aspect of Vata responsible for downward-moving functions, including menstruation, potentially contributing to irregular or absent menstrual cycles.

Stage 5: Vyakti (Manifestation)

Recognisable symptoms become apparent, such as irregular menstruation, reduced or absent ovulation, acne, unwanted hair growth or metabolic changes. The particular presentation depends on the individual's constitution and pathological pattern.

Stage 6: Bheda (Differentiation or Complications)

The condition becomes more established or develops additional complications. From a contemporary clinical perspective, these may include persistent anovulation, infertility, impaired glucose tolerance or endometrial complications.

Classical Ayurvedic Conditions Worth Exploring

Several classical concepts provide useful references for further study:

Artava Kshaya: Generally associated with diminished menstrual function, including scanty or delayed menstruation. It may offer a useful for women experiencing infrequent periods.

Nashtartava: Used in Ayurvedic discussions of absent menstruation and reproductive disturbance.

Pushpaghni Jataharini: Described in relation to anovulation and unwanted hair growth.

Granthi and Granthibhuta Artava Dushti: Sometimes used to interpret structural or reproductive disturbances associated with PMOS.

Sthaulya and Prameha: Relevant when increased adiposity or metabolic dysfunction forms part of the presentation, but not applicable to every woman with PMOS.

What Would an Ayurvedic Treatment Protocol Include?

An Ayurvedic protocol would ideally be developed from a detailed assessment of the individual's constitution, current imbalance, digestive function, menstrual history, metabolic characteristics and overall health. The aim would not simply be to stimulate menstruation, but to address the broader pattern of disturbance identified through Ayurvedic assessment.

Ahara: Dietary Management

Dietary recommendations would be guided by the individual's Agni, Dosha presentation and nutritional requirements.

For a Kapha-dominant presentation, an Ayurvedic practitioner may recommend regular meals, appropriately portioned foods, warm freshly prepared meals and a reduction in excessive heavy or highly processed foods.

Where Vata is also aggravated, overly restrictive diets, fasting or excessive consumption of dry and light foods may be inappropriate. The goal is to support adequate nourishment without contributing to further imbalance.

From a medical perspective, dietary interventions that support metabolic health are beneficial in PMOS. However, the international guidelines do not identify one particular dietary approach as superior for all women with the condition.

A practical approach may include sufficient protein, fibre-rich vegetables, legumes, whole grains, appropriate dietary fats and attention to meal regularity. These recommendations can be integrated with Ayurvedic food qualities without assuming that every woman requires the same diet.

Vihara: Lifestyle and Daily Routine

Dinacharya, or daily routine, offers a structured approach to sleep, movement, nourishment and self-care. An individualised programme might include consistent sleep and waking times, regular physical activity, time outdoors, appropriate rest and a sustainable daily rhythm. These practices are particularly relevant where fatigue, irregular sleep, emotional distress or difficulty maintaining healthy behaviours are present.

Shamana and Shodhana

Traditional Ayurvedic treatment may involve Shamana (pacifying therapies) or, in selected cases, Shodhana (purificatory therapies).

A scoping review identified 57 studies of Ayurvedic interventions for PCOS, including 13 randomised controlled trials. However, many studies were case reports or involved complex combinations of therapies, making it difficult to establish which interventions were responsible for reported improvements.

Research into Ayurvedic treatment for PMOS is still developing. Although some studies have reported improvements in menstrual regularity and metabolic markers, the quality of evidence varies considerably. Larger clinical trials are needed to establish which interventions are effective, for whom, and under what circumstances. Ayurvedic treatment should therefore be individualised and considered alongside appropriate medical assessment and care.

Yoga Therapy for PMOS: An Individualised Approach

Yoga Therapy offers a complementary approach to PMOS management by addressing physical activity, psychological wellbeing, stress regulation, sleep and the development of sustainable health behaviours.

The therapeutic rationale is particularly interesting because PMOS involves interactions between reproductive, metabolic and psychological health. A Yoga Therapy programme can work across several of these domains simultaneously.

However, Yoga Therapy should not be presented as a treatment that directly corrects ovarian pathology or reliably normalises hormone levels. The research is promising, but the strength of evidence remains limited.

What Would a Yoga Therapy Protocol Include?

A typical programme might run for 12 weeks, combining regular home practice with weekly therapeutic sessions and ongoing assessment.

Component	Therapeutic intention
Hatha Yoga and asana	Improve physical capacity, mobility, strength and consistency with movement.
Strength-focused practice	Support muscle function and metabolic health, particularly where insulin resistance is present.
Pranayama	Encourage comfortable respiratory regulation, relaxation and awareness.
Meditation	Support emotional regulation, psychological wellbeing and stress management.
Yoga Nidra and relaxation	Support rest, perceived stress reduction and sleep routines.
Lifestyle education	Encourage consistent daily routines, appropriate activity and self-management.

The actual practice would depend on the client's presentation. A woman with metabolic concerns and low physical activity may benefit from a more active programme, whereas someone experiencing significant fatigue, anxiety or poor sleep may initially require a gentler approach.

 The Ayurvedic framework can also inform how a Yoga Therapy programme is delivered.

A Kapha-dominant presentation may benefit from an energising, progressive Hatha practice that encourages strength, movement and motivation. The emphasis would be on building consistency without creating excessive fatigue.

A Vata-dominant presentation may benefit from a predictable sequence, steady movement, gentle strengthening, breath awareness and longer relaxation. The intention would be to support stability and reduce excessive stimulation.

A Pitta-dominant presentation may benefit from moderate intensity, non-competitive practice, comfortable breathing and opportunities for rest. This may be especially relevant where frustration, perfectionism or an excessively demanding exercise routine is contributing to distress.

What Does Medical Research Say About Effective Treatments?

 

The 2023 International Evidence-based Guideline for PCOS provides a strong foundation for understanding current treatment options.

Treatment	Evidence and clinical application
Lifestyle intervention	Recommended for all women with PMOS to support metabolic health and quality of life.
Combined oral contraceptive pill	Common first-line pharmacological option for menstrual irregularity and androgen-related symptoms when appropriate.
Metformin	Particularly useful for metabolic outcomes, including glucose regulation and insulin resistance.
Letrozole	First-line medication for inducing ovulation in women with anovulatory infertility when no other infertility factors are present.
Progestogen therapy	May be used to protect the uterine lining when menstruation is persistently absent.
Inositol	May be considered, but evidence for clinically meaningful benefits remains limited.

The most appropriate treatment depends on whether the primary concern is menstrual regulation, metabolic health, androgen-related symptoms, fertility or psychological wellbeing.

What About Yoga Therapy Research?

A 2023 systematic review and meta-analysis published in the International Journal of Yoga examined 11 experimental studies involving 515 participants with PCOS.

The review reported improvements in menstrual irregularity, clinical hyperandrogenism, fasting blood glucose, fasting insulin and measures of insulin resistance. However, only two randomised trials were included in the quantitative meta-analysis, and the overall certainty of evidence was rated low.

A further systematic review published in 2026 identified nine randomised controlled trials examining yoga interventions for PCOS. It reported potentially favourable metabolic, hormonal, menstrual and psychological outcomes, while highlighting small sample sizes, differences between interventions and limited generalisability.

These findings suggest that yoga may be a useful complementary intervention.

What About Ayurvedic Treatment Research?

Research into Ayurvedic treatment for PMOS is developing, but the evidence base is considerably less established. A 2023 scoping review found that many published studies investigated combinations of herbal preparations, Panchakarma and lifestyle interventions. Although individual studies reported improvements in menstrual or reproductive outcomes, the review did not establish a single effective protocol.

Integrating the Two Perspectives Responsibly

Perhaps the most valuable contribution of an integrative approach is the ability to examine PMOS from different perspectives without forcing the two medical systems to describe the same processes.

Western medicine provides diagnostic criteria, hormonal and metabolic assessment, risk screening and treatments with established clinical indications.

Ayurveda provides a traditional framework for considering constitution, digestive function, tissue nourishment, lifestyle patterns and the individual's experience of imbalance.

Yoga Therapy offers practical interventions that may support physical activity, psychological wellbeing, sleep, body awareness and self-management.

Together, these approaches can inform a comprehensive programme, provided their respective limitations are recognised.

For example, a woman presenting with irregular menstruation, insulin resistance, poor sleep and fatigue may require medical assessment and appropriate treatment for her metabolic and reproductive health. Alongside this, an Ayurvedic practitioner may assess her dietary habits, Agni and daily routine, while a Yoga Therapist develops a progressive movement programme suited to her capacity.

The aim is not to replace medical care, but to support the person more comprehensively.

It is also essential to monitor outcomes. Improvements in sleep, energy, strength, menstrual regularity and psychological wellbeing are meaningful, but they do not necessarily indicate that insulin resistance or other medical risks have resolved.

For women with PMOS, clinical follow-up may include blood pressure, cholesterol, blood glucose assessment and evaluation of menstrual frequency. Prolonged absence of menstruation also warrants medical review because of the risk of endometrial thickening.

Conclusion

PMOS illustrates the importance of understanding health beyond isolated symptoms. Although it is often recognised through menstrual irregularity or androgen-related changes, it can involve metabolic, reproductive and psychological health throughout a woman's life.

Ayurveda encourages us to examine the broader pattern of disturbance, including Agni, Dosha, Dhatu and the development of disease through Samprapti. Yoga Therapy provides practical tools for supporting movement, rest, self-awareness and sustainable lifestyle change.

The emerging research is encouraging, particularly for yoga as a complementary intervention. Nevertheless, it is important to distinguish traditional therapeutic reasoning from outcomes established through clinical research.

Understanding your diagnosis is an important part of becoming an informed participant in your own healthcare. By learning how a condition develops, what influences its symptoms and which treatment options are supported by evidence, you are better equipped to ask questions, seek appropriate support and make decisions that reflect your individual needs.
