A 2024 landmark study published in JAMA Network Open examined 9,824 Indian women and found that between 7.2% and 19.6% of women of reproductive age in India have Polycystic Ovarian Syndrome (PCOS) – with the majority carrying at least one additional metabolic condition such as dyslipidemia, obesity, or insulin resistance. Yet for millions of women, the treatment options offered remain the same: hormonal birth control, Metformin, or lifestyle advice.
What if there were a complementary, non-hormonal approach that targets the cellular root causes of PCOS – the oxidative stress, the chronic low-grade inflammation, and the insulin resistance that drive the condition forward? Hyperbaric Oxygen Therapy (HBOT) is emerging as exactly that.
At Vayu Prana, Eastern India’s first dedicated HBOT centre, we work with women whose PCOS symptoms have plateaued on conventional treatment. This guide explains what PCOS is, how HBOT addresses its biological mechanisms, what the emerging clinical evidence shows, and who is most likely to benefit.
What Is PCOS? A Quick Overview
Polycystic Ovarian Syndrome is a hormonal and metabolic disorder in which the ovaries produce an excess of androgens (male hormones), disrupting the normal cycle of ovulation. The word ‘polycystic’ refers to the many small, fluid-filled follicles that can develop in the ovaries when ovulation does not occur regularly.
PCOS is not a single condition — it is a syndrome with a wide spectrum of presentations. Some women experience it primarily as a fertility issue; others feel its impact most through its metabolic effects.
Hormones Disrupted in PCOS
- Androgens (testosterone and androstenedione) – elevated, suppressing ovulation
- Luteinising Hormone (LH) – often disproportionately raised
- Follicle-Stimulating Hormone (FSH) – relatively low, impairing follicle development
- Insulin – elevated due to resistance, further stimulating androgen production
- Oestrogen and progesterone – imbalanced due to absent or irregular ovulation
Common Symptoms
- Irregular, missed, or heavy periods
- Excess facial or body hair (hirsutism)
- Acne and oily skin
- Hair thinning or scalp hair loss
- Weight gain, particularly around the abdomen
- Darkening of the skin at the neck, armpits, or groin
- Mood changes, anxiety, and depression
- Difficulty conceiving
- Sleep apnoea
What Causes PCOS?
While the precise origin of PCOS is not fully understood, three interconnected mechanisms are consistently identified in research:
- Androgen excess: Elevated testosterone disrupts ovulation, triggers irregular periods, and causes acne and unwanted hair growth.
- Insulin resistance: When cells become resistant to insulin, the pancreas produces more of it. High insulin stimulates the ovaries to produce even more androgens, creating a self-reinforcing cycle.
- Low-grade chronic inflammation: Women with PCOS show persistently elevated inflammatory markers such as C-reactive protein (CRP). This inflammation worsens insulin resistance and amplifies androgen production.
Diagnosing PCOS
A diagnosis of PCOS is typically confirmed when at least two of the following three criteria are met (the Rotterdam criteria):
- Irregular or absent periods
- Clinical or biochemical signs of elevated androgens (excess hair, acne, or elevated testosterone on a blood test)
- Polycystic ovaries on ultrasound
Diagnosis also involves blood tests for glucose, insulin, and hormone levels, along with a pelvic ultrasound to assess ovarian and uterine health.
Conventional Treatments for PCOS
Standard management of PCOS typically involves:
For Women Not Planning Pregnancy
- Hormonal contraceptives (pills, patches, injections, IUDs) to regulate periods, reduce androgens, and manage acne
- Metformin to improve insulin sensitivity
- Anti-androgen medications to address hirsutism and acne
- Dietary changes and weight management
For Women Seeking Pregnancy
- Ovulation-inducing medications such as clomiphene or letrozole
- Injectable gonadotropins
- Laparoscopic ovarian drilling (now less common)
- In vitro fertilisation (IVF) when other approaches fail
These treatments address symptoms effectively, but they do not resolve the underlying cellular dysfunction – the oxidative stress and chronic inflammation that continue to drive PCOS even when hormones are medically suppressed. This is where HBOT offers a meaningful adjunctive role.
What Is HBOT and How Does It Work?
Hyperbaric Oxygen Therapy (HBOT) involves breathing 100% pure medical-grade oxygen in a specially pressurised chamber, typically at 2 to 3 times normal atmospheric pressure. At this elevated pressure, oxygen dissolves far more readily into the blood plasma – far beyond the limits of haemoglobin-bound transport.
The result is a dramatic increase in tissue oxygenation throughout the body. Organs, glands, and tissues that are chronically under-oxygenated due to poor circulation or inflammation receive a sustained flood of oxygen with each session.
According to the Undersea and Hyperbaric Medical Society (UHMS), HBOT is defined as treatment in which a patient intermittently breathes 100% oxygen at pressures greater than 1.4 atmospheres absolute (ATA). At Vayu Prana, sessions operate at 2 to 2.4 ATA for most therapeutic protocols.
How Does HBOT Address the Root Causes of PCOS?
PCOS is fundamentally a condition of oxidative stress, inflammation, and insulin resistance at the cellular level. HBOT targets all three:
1. Reducing Oxidative Stress
Women with PCOS have significantly elevated levels of reactive oxygen species (ROS) – unstable molecules that damage cells, disrupt hormonal signalling, and impair ovarian function. HBOT stimulates the body’s endogenous antioxidant systems, particularly superoxide dismutase (SOD), an enzyme that neutralises ROS.
A controlled study using an insulin-resistant PCOS rat model found that HBOT at 2.4 ATA significantly increased SOD serum levels while simultaneously reducing androgen receptor (AR) expression – a key driver of hyperandrogenism. The researchers concluded that HBOT may be a viable option for insulin-resistant PCOS patients.
2. Improving Insulin Sensitivity
A 2025 review published in Antioxidants examining evidence from 2012–2025 confirmed that HBOT enhances insulin sensitivity, reduces adipose tissue inflammation, and modulates lipid metabolism in preclinical models. By reducing the inflammatory environment that sustains insulin resistance, HBOT may help break the insulin-androgen cycle that maintains PCOS.
3. Reducing Chronic Inflammation
HBOT has well-established anti-inflammatory effects. It downregulates pro-inflammatory cytokines, reduces tissue oedema, and supports the resolution of chronic low-grade inflammation. For PCOS patients, this translates to a potentially improved hormonal environment – less inflammatory signalling driving androgen excess.
4. Supporting Ovarian Function and Follicle Development
High tissue oxygenation stimulates angiogenesis – the growth of new blood vessels. Improved vascularity around the ovaries can enhance oxygen and nutrient delivery, supporting healthier follicle maturation. A pilot study published in Fertility and Sterility found that HBOT may increase follicular fluid VEGF (vascular endothelial growth factor) levels, which is critical to follicular development, oocyte quality, and early embryo development. Two women in the study conceived following HBOT combined with IVF.
5. Post-Surgical Ovarian Reserve Recovery
For women who have undergone laparoscopic ovarian cystectomy, HBOT has demonstrated a meaningful role in protecting ovarian reserve post-operatively. In a 60-patient controlled study, the group receiving adjuvant HBOT after surgery showed significantly better postoperative levels of anti-Müllerian hormone (AMH), FSH, LH, and estradiol compared to the control group – markers that reflect the ovarian reserve and egg-producing capacity of the ovaries.
What Does HBOT Treatment Look Like?
Understanding what to expect can remove the barrier of the unknown. Here is what a typical HBOT experience at Vayu Prana involves:
1. Pre-treatment assessment: A certified hyperbaric specialist reviews your full medical history, current medications, PCOS severity, and metabolic markers. All patients are clinically cleared before beginning.
2. Entering the chamber: You recline comfortably in a monoplace (single-person) or multiplace chamber. You may read, listen to audio content, or rest quietly.
3. Pressurisation: The chamber pressure gradually increases over approximately 10–15 minutes. You may feel mild ear pressure similar to descending in an aeroplane – easily relieved by swallowing or yawning.
4. Oxygen delivery: At the target pressure (typically 2–2.4 ATA), you breathe 100% oxygen continuously for the therapeutic period, usually 60–110 minutes.
5. Depressurisation: Pressure is slowly released over 15–20 minutes. The session concludes comfortably and without discomfort.
For PCOS management, most protocols involve multiple sessions administered over several weeks, with frequency and duration tailored to your individual clinical profile.
Who Is Most Likely to Benefit From HBOT for PCOS?
HBOT as a complementary therapy for PCOS is particularly relevant for women who:
- Have insulin-resistant PCOS that has not responded fully to Metformin alone
- Experience significant oxidative stress symptoms (fatigue, brain fog, chronic skin issues)
- Are preparing for or have recently undergone ovarian surgery
- Are planning IVF and wish to optimise ovarian response
- Have PCOS alongside chronic inflammation or metabolic syndrome
- Prefer to minimise long-term hormonal medication use
It is important to note that HBOT is adjunctive – it works best alongside, not instead of, conventional treatment and lifestyle management. Your team at Vayu Prana will coordinate with your gynaecologist or endocrinologist to design an integrated plan.
A Note on Current Research
The evidence base for HBOT in PCOS is growing but still considered emerging. Most studies to date have been conducted in animal models or small clinical cohorts. The rat model research on AR expression and SOD levels is promising, and the post-surgical ovarian reserve study shows meaningful human clinical data. However, large-scale randomised controlled trials specifically targeting PCOS are yet to be conducted.
This is why Vayu Prana positions HBOT as a complementary and adjunctive treatment — not a replacement for proven PCOS therapies. Our role is to add a powerful biological tool to your existing treatment plan, with full transparency about what the current evidence supports.

Frequently Asked Questions (FAQs)
1. Is HBOT a cure for PCOS?
No. HBOT is not a cure for PCOS. It is a complementary, adjunctive therapy that targets the cellular and metabolic drivers of PCOS – oxidative stress, insulin resistance, and chronic inflammation. It works best as part of a comprehensive treatment plan that includes hormonal management, dietary changes, and regular medical supervision.
2. How many HBOT sessions are needed for PCOS?
The number of sessions varies depending on your individual presentation, metabolic markers, and treatment goals. Most protocols range from 10 to 30 sessions. Your specialist at Vayu Prana will recommend a personalised plan following your initial clinical assessment.
3. Is HBOT safe for women with PCOS?
HBOT is generally well-tolerated and safe for most women when administered under clinical supervision. Before beginning any protocol, every patient at Vayu Prana undergoes a thorough medical evaluation to confirm suitability and identify any contraindications. Conditions such as untreated pneumothorax, certain respiratory conditions, or claustrophobia may affect candidacy.
4. Can HBOT help with PCOS-related infertility?
Emerging evidence suggests HBOT may improve ovarian function, support follicle development, and enhance post-surgical ovarian reserve – all of which are relevant to fertility in women with PCOS. A pilot study in Fertility and Sterility found that HBOT may improve IVF outcomes in women with poor prognosis. However, it should be considered a supportive adjunct to reproductive medicine, not a standalone fertility treatment.
5. Will HBOT help with my irregular periods?
By reducing the underlying oxidative stress and insulin resistance that disrupt hormonal balance in PCOS, HBOT may contribute to improved hormonal regulation over time. Clinical studies have shown improvements in FSH, LH, and estradiol levels following HBOT in ovarian cyst patients. However, direct evidence specifically linking HBOT to menstrual cycle normalisation in PCOS remains limited, and conventional hormonal management remains the primary approach.
6. Can I continue my current PCOS medication while undergoing HBOT?
In most cases, yes. HBOT is designed to work alongside conventional treatment, not replace it. Your Vayu Prana specialist will review all current medications and coordinate with your prescribing physician before designing your HBOT protocol.
7. Is HBOT available in Kolkata for PCOS?
Yes. Vayu Prana is Eastern India’s first dedicated Hyperbaric Oxygen Therapy centre in Kolkata. We offer clinically supervised HBOT for a range of conditions including PCOS and hormonal health. Contact us to book an initial consultation.
Conclusion: A New Angle on an Old Struggle
PCOS affects millions of Indian women – and the burden is not just hormonal. It is metabolic, inflammatory, and deeply personal. For women who have been managing PCOS for years through hormones and Metformin alone, HBOT represents a scientifically grounded, non-invasive option to address what those treatments leave untouched: the oxidative environment, the inflammatory signalling, and the insulin-androgen cycle at the cellular level.
The research is still maturing, but the mechanisms are sound and the early clinical evidence is encouraging. At Vayu Prana, our approach is always transparent and integrative – we work with your existing care team to add HBOT where it can make the most meaningful difference.
If you have PCOS and want to explore whether HBOT is right for you, book a consultation with our specialist team today. Your first session begins with an honest, thorough assessment – because every woman’s PCOS journey is different.
