Functional Medicine Approach to PCOS

Functional Medicine for PCOS in India should look beyond irregular periods, ovarian cysts or weight alone. Polycystic ovary syndrome — PCOS — is a common hormonal and metabolic condition that can affect menstrual cycles, ovulation, androgen levels, fertility, body composition and long-term metabolic health.

PCOS affects an estimated 10–13% of women of reproductive age, and many women remain undiagnosed. It is also associated with a higher risk of insulin resistance, Type 2 Diabetes, obesity and other metabolic concerns. World Health Organization

At RH+, I do not look at PCOS simply as a problem of irregular periods or ovarian appearance on ultrasound.

With Prashantt J Wadhaawan, Functional Medicine Practitioner and Founder of RH+, the assessment considers the individual’s age, weight and body composition, menstrual and PMS history, acne and other androgen-related symptoms, food habits, insulin regulation, exercise, gut health, sleep, stress and broader metabolic health together.

The aim is to understand the patterns that may be contributing to symptoms and metabolic dysfunction, and then build a personalised strategy around nutrition, movement, sleep, stress management and other relevant factors alongside appropriate medical care.

Online functional medicine consultations are available across India.

PCOS Is More Than a Period Problem

Women with PCOS can present very differently.

One person may primarily struggle with:

• irregular or absent periods
• difficulty losing weight
• cravings
• insulin resistance
• acne
• increased facial or body hair
• hair thinning
• infertility
• PMS symptoms
• poor sleep
• digestive problems
• fatigue

while another may have only a few of these features.

This is one reason I do not think every woman with PCOS should receive the same diet, supplement stack or exercise programme.

“PCOS is not just a period problem. I look at the metabolic, lifestyle, gut, sleep and stress patterns around it.” — Prashantt J Wadhaawan

How PCOS Is Diagnosed

PCOS should be appropriately diagnosed rather than assumed from symptoms alone.

Current international guidance uses criteria based on the presence of at least two of the following, once other causes have been excluded:

• clinical or biochemical evidence of excess androgens
• ovulatory dysfunction or irregular menstrual cycles
• polycystic ovarian morphology on ultrasound, or in some adult situations AMH as an alternative according to current guidance

Importantly, not everyone with PCOS has polycystic ovaries on ultrasound, and ovarian cysts are not required for diagnosis. World Health Organization

In adolescents, diagnostic criteria are more restrictive because irregular cycles and ovarian morphology can overlap with normal pubertal development. ASRM

How I Assess PCOS

I begin with the person rather than immediately deciding that every problem is caused by hormones.

Age & Life Stage

Age matters because PCOS can present differently in adolescence, reproductive years and later stages of life.

Menstrual & PMS History

I want to understand:

• cycle length
• irregularity
• missed periods
• heavy bleeding
• PMS symptoms
• changes over time
• previous contraception
• fertility history where relevant

Weight & Body Composition

I look beyond the weighing scale to consider:

• body-fat distribution
• visceral fat
• muscle mass
• weight history
• previous weight-loss attempts

Skin & Androgen-Related Symptoms

These may include:

• acne
• oily skin
• facial or body hair
• scalp hair thinning

Nutrition & Eating Patterns

I review:

• food quality
• meal frequency
• portion size
• cravings
• carbohydrate quality
• fibre intake
• overeating
• restrictive dieting
• meal timing

Exercise & Physical Activity

I look at daily movement, resistance training, cardio and the person’s overall fitness level.

Sleep & Stress

Both are routinely assessed because poor sleep and chronic stress can make metabolic and behavioural management more difficult.

Gut Health

I also look at digestive symptoms, bowel habits, food-related symptoms and dietary tolerance where relevant.

Blood Markers & Investigations To Review In PCOS

Depending on the individual and what has already been investigated medically, I may review:

Metabolic Markers

• fasting glucose
• HbA1c
• fasting insulin where appropriate
• C-peptide where useful
• triglycerides
• HDL and broader lipid profile
• liver enzymes

Hormonal Markers

Where appropriate:

• total testosterone
• free testosterone or calculated free androgen measures
• SHBG
• DHEA-S
• LH
• FSH
• prolactin
• other reproductive hormones according to the clinical question

Thyroid & Nutritional Health

Depending on symptoms:

• TSH and relevant thyroid markers
• ferritin and iron status
• vitamin D
• vitamin B12
• other nutritional markers

Imaging

Pelvic ultrasound may be relevant depending on diagnostic context.

But ultrasound is not the whole diagnosis, and the absence or presence of polycystic ovarian morphology does not tell us everything about the person’s metabolic health. ASRM

PCOS & Insulin Resistance

This is one of the most important areas I consider.

Many women with PCOS have some degree of insulin resistance, although not every woman with PCOS is insulin resistant or overweight.

Where insulin resistance is present, it may contribute to:

• increased hunger
• cravings
• weight gain
• visceral fat
• difficulty losing weight
• metabolic abnormalities

The international PCOS guideline recommends assessing glycaemic status because women with PCOS have an increased risk of impaired glucose tolerance and Type 2 Diabetes. ASRM

Weight & PCOS

Weight management can be important in PCOS when excess body fat is present.

But I do not want every woman with PCOS to believe that:

PCOS = overweight

or:

weight loss = the only goal

Some women with PCOS are lean.

Others have significant visceral obesity and insulin resistance.

The strategy therefore depends on the individual’s:

• body composition
• metabolic health
• eating pattern
• activity
• sleep
• stress
• hormonal profile

Where weight loss is appropriate, my goal is to reduce excess fat while preserving or improving muscle.

One of the Commonest Problems I See in PCOS: Too Much Eating

One practical pattern I commonly see in women with PCOS is excessive or poorly structured eating.

This may involve:

• frequent eating
• constant snacking
• large portions
• cravings
• highly processed foods
• irregular meals
• emotional or stress-related eating

The answer is not necessarily extreme calorie restriction.

The goal is to establish a more controlled nutritional environment in which the person feels sufficiently nourished and satisfied without constantly needing to eat.

Sleep & PCOS

Sleep is one of the areas I frequently find neglected.

Women with PCOS have a higher prevalence of sleep problems, including obstructive sleep apnoea, particularly when other risk factors are present. Current PCOS guidance recommends attention to symptoms such as snoring, waking unrefreshed and daytime sleepiness. ASRM

In practice, I review:

• sleep duration
• sleep quality
• sleep and wake timing
• night waking
• snoring
• daytime fatigue
• stimulant use

Trying to improve metabolism while consistently sleeping poorly leaves an important piece of the picture unresolved.

Stress & PCOS

Stress does not mean that PCOS is “caused by stress.”

But chronic stress can affect:

• eating behaviour
• sleep
• cravings
• recovery
• exercise adherence
• overall wellbeing

For some women, the sequence becomes:

stress → poor sleep → more cravings → overeating → less exercise → weight gain → greater metabolic burden

Breaking that cycle can be more useful than simply adding another supplement.

Gut Health & PCOS

Gut health is another area I assess, but I do not assume that everyone with PCOS has a microbiome disorder.

Some women also report:

• bloating
• constipation
• reflux
• altered bowel habits
• food-related symptoms
• restrictive eating
• nutritional deficiencies

When these are present, I want to know whether digestive health is interfering with:

• dietary quality
• nutrient intake
• appetite
• energy
• adherence to a sustainable nutrition plan

The gut microbiome is being studied in relation to PCOS, but current evidence does not justify claiming that correcting the microbiome will cure PCOS.

PCOS, Acne & Androgen Symptoms

Higher androgen activity can contribute to:

• acne
• excess facial or body hair
• scalp hair thinning

These symptoms can significantly affect quality of life and should not be dismissed as cosmetic.

Medical treatment may be appropriate.

At RH+, I also consider whether broader metabolic, nutritional, lifestyle or sleep factors are relevant to the individual’s overall health.

The aim is not to promise that diet or supplements will eliminate androgen-related symptoms.

PMS & Menstrual Symptoms

Although PMS is not the defining feature of PCOS, many women report significant cycle-related symptoms.

I assess:

• timing of symptoms
• mood changes
• appetite and cravings
• bloating
• breast symptoms
• sleep changes
• cycle regularity

The objective is to understand the complete menstrual pattern rather than simply asking whether periods are present or absent.

One of the outcomes I often look for is less disruptive PMS and more predictable cycles, where that is realistically achievable.

Exercise & PCOS

Exercise should match the person’s starting point.

For someone who is:

• significantly overweight
• sedentary
• inexperienced with exercise

I may begin with progressively increasing walking and daily movement.

As fitness improves, structured resistance training can be introduced.

For women already familiar with exercise, resistance training and cardiovascular exercise can be used more strategically from the beginning.

Current PCOS guidance recommends healthy lifestyle behaviours—including physical activity—for all women with PCOS, regardless of whether weight loss occurs. ASRM

Why Muscle Matters in PCOS

Muscle is highly relevant to metabolic health.

Where appropriate, I want to improve the person’s muscle-to-fat ratio, not simply make them lighter.

Resistance training can form part of a strategy to support:

• body composition
• physical strength
• insulin sensitivity
• long-term metabolic health

This becomes especially relevant when insulin resistance and excess body fat are present.

Do Women With PCOS Need a Low-Carbohydrate Diet?

Not automatically.

There is no single diet that current international guidelines identify as superior for every woman with PCOS. Dietary patterns should be individualised and sustainable. ASRM

I may adjust carbohydrate intake according to:

• insulin resistance
• body composition
• activity level
• food preferences
• triglycerides
• glucose regulation
• overall dietary pattern

But I do not automatically prescribe permanent keto or extremely low-carbohydrate diets to every woman with PCOS.

PCOS & Fatty Liver

PCOS can overlap with metabolic conditions such as:

• insulin resistance
• obesity
• abnormal lipids
• Type 2 Diabetes
• fatty liver

Where liver markers or metabolic history suggest concern, I look at liver health as part of the wider assessment.

PCOS & Thyroid Health

Symptoms such as:

• weight change
• menstrual irregularity
• fatigue
• hair changes

can also occur in thyroid disorders.

This is one reason thyroid disease may need to be excluded or appropriately assessed rather than assuming every symptom is caused by PCOS.

Explore Thyroid Health →

What About Supplements For PCOS?

Supplements may have a role when there is a clear reason for using them.

Depending on the individual, this may involve correcting nutritional deficiencies or using selected evidence-informed interventions.

But I do not want PCOS management to become:

inositol + vitamin D + omega-3 + supplement stack = treatment

without addressing:

• food quality
• overeating
• sleep
• stress
• activity
• body composition
• insulin resistance

Supplements should support the strategy rather than become the strategy.

PCOS & Fertility

PCOS is one of the most common causes of ovulatory infertility. World Health Organization

If fertility is the priority, the approach may need to involve:

• appropriate gynaecological assessment
• ovulation assessment
• metabolic health
• weight management where relevant
• appropriate fertility treatment

Functional medicine should complement appropriate reproductive care rather than delay it.

What Are We Actually Trying to Improve In PCOS?

My goal is not simply:

“Make the ultrasound look normal.”

Depending on the individual, I want to see improvement in:

• menstrual regularity
• PMS symptoms
• insulin sensitivity
• cravings
• body weight where appropriate
• visceral fat
• body composition
• sleep
• energy
• glucose regulation
• triglycerides and metabolic markers
• liver health
• androgen-related symptoms
• fertility-related health where relevant

Follow-up ultrasound may provide useful information in selected cases, but ovarian morphology is only one component of PCOS and should not become the sole outcome.

“My goal is not simply to make periods regular. It is to improve the metabolic and hormonal environment that supports healthier cycles.” — Prashantt J Wadhaawan

10. Reassess

Track:

cycles + symptoms + body composition + metabolic markers + sleep + cravings + overall health

over time.

When Medical or Gynaecological Evaluation Is Important In PCOS

PCOS requires appropriate medical evaluation, particularly when there is:

• very irregular or absent menstruation
• prolonged absence of periods
• heavy or abnormal bleeding
• infertility
• rapidly increasing facial/body hair
• severe acne
• rapidly worsening androgen symptoms
• significant pelvic pain
• pregnancy
• suspected diabetes
• major metabolic abnormalities
• symptoms suggesting another endocrine disorder

Irregular or infrequent menstruation in PCOS can increase the risk of endometrial hyperplasia, so this should not simply be ignored. World Health Organization

PCOS FAQs

Can PCOS be cured?

PCOS is generally considered a chronic condition rather than something that can universally be cured. Symptoms and metabolic abnormalities can often be substantially improved with appropriate lifestyle and medical management. World Health Organization

Does PCOS always cause weight gain?

No. Women with PCOS can have a wide range of body weights and body compositions.

Does everyone with PCOS have insulin resistance?

No. Insulin resistance is common in PCOS but is not present to the same degree in every individual.

Do I need an ultrasound to diagnose PCOS?

Not always. Under current international guidance, when irregular cycles and hyperandrogenism are already present, ultrasound or AMH may not be required for diagnosis in adults. ASRM

Can I have PCOS without ovarian cysts?

Yes. Despite the name, polycystic ovaries are not required in every person diagnosed with PCOS. World Health Organization

Is weight loss useful for PCOS?

For women carrying excess body fat, sustainable weight reduction can improve metabolic health and may improve some PCOS symptoms. Lifestyle management is recommended for all women with PCOS, including those who do not need to lose weight. ASRM

Do I need to stop carbohydrates?

No. There is no single mandatory PCOS diet, and current international guidelines do not support one specific macronutrient composition as superior for everyone. ASRM

Can poor sleep affect PCOS management?

Yes. Poor sleep can influence wellbeing, appetite, activity and metabolic health. Women with PCOS also have an increased risk of obstructive sleep apnoea, especially when other risk factors are present. ASRM

Is gut health important in PCOS?

Gut health may be relevant when gastrointestinal symptoms or dietary problems are present, but PCOS should not automatically be attributed to a gut disorder.

Can PCOS affect fertility?

Yes. PCOS is a common cause of ovulatory infertility, but many women with PCOS can become pregnant naturally or with appropriate fertility support. World Health Organization

Can I stop metformin if my cycles improve?

Do not stop or change prescribed medication without discussing it with the prescribing healthcare professional.

Can I consult online for PCOS?

Yes. RH+ provides online functional medicine consultations across India where remote support is appropriate.
