PCOS Overview Medically reviewed

What is PCOS? A clear overview

One of the most common hormonal conditions in women of reproductive age — and one of the most misunderstood. This medically reviewed overview explains what PCOS is, its main features, and how it affects the body, in plain language.

In short

PCOS (polycystic ovary syndrome) is a common hormonal and metabolic condition affecting women of reproductive age. It can cause irregular periods, signs of higher androgen levels, and changes on an ovary scan. It can't usually be cured, but it's highly manageable — and many women with PCOS who want to conceive eventually can.

Understanding PCOS

What is PCOS?

A closer look at what polycystic ovary syndrome actually is — the hormonal and metabolic changes behind it, and how common it really is.

PCOS is a common hormonal and metabolic condition in which the ovaries, the hormones that control them, and the way the body handles insulin fall out of their usual balance. This can disrupt ovulation, raise androgen ("male" hormone) levels, and show up as multiple small follicles on an ovary scan.

Despite the name, PCOS is not really about "cysts." The small follicles seen on a scan are immature eggs that haven't been released, not harmful growths. PCOS sits across three body systems at once — endocrine, reproductive, and metabolic — which is why its effects can range from irregular periods and skin changes to longer-term effects on weight and blood sugar. It tends to run in families, and while it can't usually be cured, its features can be managed well over time.

Key takeaways
  • PCOS is a hormonal and metabolic condition, not just an ovary problem.
  • The "cysts" are actually small immature follicles — not dangerous growths.
  • It commonly affects periods, androgen levels, and insulin — to different degrees in different people.
  • PCOS can't usually be cured, but it is highly manageable with the right care.

How common is PCOS?

PCOS is one of the most common hormonal conditions in women of reproductive age — but exactly how common depends heavily on which diagnostic criteria are used, which is why published figures vary so widely.

Worldwide ~6–13% of women of reproductive age, depending on the criteria used WHO (opens in a new tab)
India ~11–22% across community and clinic-based estimates by criteria ICMR-linked review, 2023 (opens in a new tab)

What this means for youThe wide range doesn't mean the data is unreliable — it reflects that PCOS is defined differently by different guidelines, and that broader (Rotterdam) criteria identify more people than stricter ones. If you recognise the features of PCOS in yourself, the prevalence figures matter less than getting assessed: a healthcare professional can confirm whether what you're experiencing fits PCOS and what, if anything, to do next.

How PCOS works

How PCOS affects the body

PCOS isn't caused by one single thing going wrong. It comes from three drivers that feed into each other — which is why it shows up so differently from person to person.

In PCOS, three systems drift out of balance and reinforce one another: the ovaries make more androgens than usual, the body becomes less responsive to insulin, and ovulation becomes irregular. Each one can nudge the others along, which is what makes PCOS a cycle rather than a single fault. The mix differs from person to person — and that's why no two experiences of PCOS look quite the same.

  • Higher androgen levels

    Slightly raised "male" hormones can affect periods, skin and hair. It's one of the most recognised features of PCOS, though not everyone has visible signs.

  • Insulin resistance

    Many people with PCOS need more insulin to keep blood sugar steady. Higher insulin can, in turn, push androgen levels up — linking PCOS to weight and long-term blood-sugar health.

  • Disrupted ovulation

    When the hormonal signals that release an egg are interrupted, periods become irregular or absent — the change most likely to affect fertility.

PCOS phenotypes

Are there different types of PCOS?

You'll often see PCOS split into "types" online. Here's what the medical evidence actually says — and the recognised classification doctors really use.

PCOS is not officially divided into separate "types." Instead, doctors describe it using four recognised phenotypes (A–D), based on which of three core features a person has. They're all the same condition — the phenotype simply captures how it shows up.

PCOS is diagnosed using the Rotterdam criteria — any two of these three features:
High androgens Raised "male" hormones — by blood test or signs like acne or excess hair
Ovulation problems Irregular, infrequent or absent periods from disrupted ovulation
Polycystic ovaries Many small follicles visible on an ovary ultrasound
Phenotype A Classic PCOS
HA OD PCOM

All three features present. The most studied form, and the one most often linked with insulin and metabolic effects.

Phenotype B Hyperandrogenic anovulation
HA OD PCOM

High androgens with irregular ovulation, but ovaries appear typical on a scan.

Phenotype C Ovulatory PCOS
HA OD PCOM

High androgens and polycystic ovaries, but periods stay regular. Common in Indian clinic data.

Phenotype D Non-hyperandrogenic
HA OD PCOM

Irregular ovulation and polycystic ovaries, without raised androgens. Often the mildest metabolic profile.

A note on "insulin-resistant, inflammatory, adrenal and post-pill PCOS"

You may have seen PCOS sorted into these four labels. They come from wellness writing, not from medical guidelines, and aren't a recognised diagnostic classification. Insulin resistance and inflammation are real and important features many people with PCOS share — but they don't define separate diseases. For diagnosis and treatment, clinicians use the Rotterdam phenotypes above. If a label helps you make sense of your own pattern, that's fine — just don't expect a doctor to diagnose by it.

Signs & symptoms

Common signs and symptoms of PCOS

PCOS shows up differently in different people. Some notice changes to their periods or skin early on; others mainly notice effects on weight or fertility. Most people have only some of these — not all.

The most common signs of PCOS are irregular or missed periods, signs of higher androgens (such as acne or extra facial and body hair), and changes in weight. Less obvious signs can include hair thinning on the scalp, darkened skin patches, mood changes, and difficulty conceiving. Symptoms often start around the teens or early twenties and can shift over time.

Most common signs

  • Irregular or missed periods Cycles that are long, unpredictable, or stop for months — the most common sign.
  • Acne & oily skin Persistent breakouts, often along the jaw and chin, linked to higher androgens.
  • Excess facial & body hair Coarser hair on the face, chest or back (hirsutism), a recognised sign of PCOS.
  • Weight changes Weight gain or difficulty losing weight, often linked to how the body handles insulin. Weight & PCOS

Less obvious or longer-term signs

  • Scalp hair thinning Gradual thinning at the crown or hairline (female-pattern hair loss).
  • Dark skin patches Velvety darkening in folds like the neck or underarms (acanthosis nigricans), a possible sign of insulin resistance.
  • Mood changes Low mood or anxiety are more common with PCOS, and are treatable — they're not something to simply put up with.
  • Difficulty conceiving Irregular ovulation can make conceiving harder — but many women with PCOS do conceive. PCOS & fertility

Worth knowing Signs like acne, irregular periods or extra facial hair are often brushed off as cosmetic or "just hormonal," so PCOS can go unrecognised for years. If several of these appear together, it's worth raising with a doctor rather than treating each one separately.

When to see a doctor

It's a good idea to get checked if your periods are regularly irregular or absent, if acne or excess hair is bothering you, or if you've been trying to conceive for a while without success. None of these is an emergency — but getting assessed early means PCOS can be managed sooner. A doctor can confirm what's going on and suggest next steps.

Key takeaways
  • Irregular periods, androgen signs (acne/hair) and weight changes are the most common symptoms.
  • Most people have only some of these signs — the mix varies a lot.
  • Symptoms are manageable, and getting assessed early helps.

Causes & risk factors

What causes PCOS, and who's more at risk?

There's no single cause of PCOS. It develops from a mix of factors — some you're born with, others shaped by metabolic health and lifestyle. Understanding them helps explain why PCOS runs in families and why it often overlaps with blood-sugar issues.

The exact cause of PCOS isn't fully known. Most research points to a combination of genetic and metabolic factors rather than one trigger. A family history of PCOS, the way the body handles insulin, and hormonal balance all play a part — and they interact, which is why PCOS looks different from one person to the next. Having a risk factor doesn't mean you'll definitely develop PCOS.

Factors you can't change

Non-modifiable
  • Family history & genetics PCOS often runs in families. If your mother or sister has it, your likelihood is higher — it's thought to involve several genes, not just one.
  • Early hormonal influences Hormone exposure early in development is thought to shape how PCOS emerges later — an area researchers are still studying.
  • Ethnic background Some features, like insulin resistance, are more common in South Asian women, which can affect how PCOS presents.

Factors that can be influenced

Modifiable
  • Insulin & metabolic health How the body responds to insulin strongly influences PCOS. Improving insulin sensitivity can ease several features over time.
  • Body weight Carrying extra weight can intensify PCOS features for some people — though PCOS also affects those at a healthy weight, and weight isn't the cause.
  • Daily habits Activity levels, eating patterns and sleep all interact with insulin and hormones, so they can shift how PCOS feels day to day.
Risk factors aren't blame

PCOS isn't caused by anything you did wrong. Modifiable factors are simply the parts of the picture that respond to care — not a verdict on lifestyle. Many people with a healthy lifestyle still develop PCOS because of factors set long before symptoms appear.

India context Insulin resistance tends to be more common in South Asian women, often at a lower body weight than in some other populations. That's one reason PCOS in India can appear in people who don't fit the "expected" picture — and why blood-sugar health is worth checking even when weight seems typical.

PCOS is described as a condition of unknown cause involving genetic and environmental factors by the NIH / StatPearls clinical review (opens in a new tab).

Diagnosis

How is PCOS diagnosed?

There's no single test for PCOS. Doctors diagnose it using a recognised set of criteria — and by first ruling out other conditions that can look similar.

PCOS is diagnosed using the Rotterdam criteria: a doctor confirms it when two of three features are present — higher androgens, irregular ovulation, or polycystic ovaries on a scan — after ruling out other conditions that can cause the same signs. Because of this, diagnosis always needs a doctor; it can't be confirmed from symptoms or a scan alone.

2 of 3 Any two of these three features are needed for a diagnosis
  1. Higher androgens Shown by a blood test, or by signs like persistent acne or excess facial and body hair.
  2. Irregular ovulation Irregular, infrequent or absent periods — often cycles longer than 35 days, or fewer than 8 a year.
  3. Polycystic ovaries Many small follicles seen on an ultrasound. On its own, this finding is common and doesn't confirm PCOS.
To assess these features, a doctor usually combines:
History & examination Your cycle pattern, symptoms and a physical check.
Blood tests Androgen levels, plus tests to rule out look-alike conditions.
Ultrasound A pelvic scan to look at the ovaries, where needed.
Why other tests are done first

PCOS is a "diagnosis of exclusion." Conditions like thyroid problems or raised prolactin can cause irregular periods or androgen signs too, so a doctor checks for these before confirming PCOS. It's not extra caution — ruling them out is part of the diagnosis. This is also why self-diagnosing from a symptom list isn't reliable.

Tests & tools

Tests often linked to PCOS

No single test diagnoses PCOS, but a doctor may use several to assess its features and rule out other causes. Here's what each one looks at — explore any test for its normal ranges and what results mean.

The tests most often used around a PCOS assessment fall into three groups: hormone tests (to check androgens and ovulation signals), metabolic tests (because PCOS frequently affects blood sugar and cholesterol), and exclusion tests (to rule out thyroid or other conditions that mimic PCOS). Which ones a doctor orders depends on your symptoms — not everyone needs all of them.

Hormone tests

Which tests you need, and how to read them, is a decision for you and your doctor — results are interpreted together, not in isolation. To explore your numbers, try our BMI calculator as a starting point, then discuss any tests with a healthcare professional.

Treatment

How is PCOS treated?

PCOS can't usually be cured, but it responds well to treatment. Care is tailored to your symptoms and goals — whether that's steadier periods, calmer skin, better metabolic health, or planning a pregnancy.

There's no single treatment for PCOS, and no cure — but its features are very manageable. Care usually starts with supported lifestyle changes and adds medication where helpful: hormonal options for irregular periods and skin signs, insulin-focused options for metabolic health, and specific treatments when you're trying to conceive. The right mix depends on what's affecting you most.

  • First step for everyone

    Lifestyle & metabolic care

    Supported changes to activity, eating and sleep are the foundation of PCOS care, helping insulin and hormones across all symptoms.

    PCOS diet & lifestyle
  • For periods & skin

    Hormonal treatment

    Hormonal options are commonly used to regulate periods and ease androgen-related signs like acne or excess hair. A doctor will discuss what suits you.

    Treatment options
  • For metabolic health

    Insulin-focused options

    Where insulin resistance is a factor, medication may be added alongside lifestyle to support blood-sugar health and other features.

    How this works
  • When planning a pregnancy

    Fertility support

    If you're trying to conceive, specific treatments can help encourage ovulation. Many people with PCOS go on to have healthy pregnancies.

    PCOS & fertility

Most people with PCOS find a combination that works for them, often adjusting it over time. Treatment choices — including any medication — should always be made with a doctor, who can weigh the benefits and side effects for your situation. See the full treatment guide.

Treatment framing follows the 2023 International Evidence-Based PCOS Guideline (opens in a new tab).

Diet & nutrition

Eating well with PCOS

There's no single "PCOS diet," and no food is off-limits forever. What helps most is a steady, balanced way of eating that supports blood sugar — built around foods you actually enjoy and can keep up.

For PCOS, the most useful eating pattern is one that keeps blood sugar steady: balanced meals that combine fibre, protein and healthy fats with carbohydrates, rather than carbohydrates alone. No single diet has been shown to beat others — so the best plan is a balanced one you can sustain. Indian meals can absolutely fit this; it's about balance and portion, not giving up rice or roti.

Helpful to build meals around

  • Fibre-rich whole foodsWhole grains, dals, beans, vegetables and fruit with the skin — they slow how fast sugar enters the blood.
  • Protein with each mealDairy, eggs, paneer, fish, chicken, soya or legumes — protein helps meals feel filling and steady.
  • Healthy fatsNuts, seeds, and oils used sensibly add satisfaction and help balance a meal.

Worth keeping in check

  • Sugary drinks & sweetsThese raise blood sugar quickly. Enjoyed occasionally is fine — it's the everyday habit that matters.
  • Refined carbs aloneWhite bread, maida and large portions of plain rice hit harder on their own — pairing them with protein and veg helps.
  • Heavily processed snacksPackaged fried and ultra-processed foods add little and are easy to over-eat.

India context A typical Indian plate can work well for PCOS with small tweaks: more dal and vegetables, a little more protein, and being mindful of portion size with rice or roti rather than cutting them out. Balance beats restriction — overly strict diets are hard to sustain and can backfire.

Everyone's needs differ — for a plan suited to you, especially if you have other conditions, it's worth speaking with a doctor or a registered dietitian.

Movement & activity

Exercise and movement for PCOS

Movement is one of the most effective ways to support PCOS — not because of how it changes the scale, but because of how it helps insulin, mood and energy. The best routine is the one you'll actually keep doing.

Regular activity helps PCOS mainly by improving how the body uses insulin, which can ease several features over time. A mix of movement you enjoy and some strength work tends to help most — but consistency matters far more than intensity. Even small, regular activity counts, and benefits show up well before any change in weight.

  • Everyday movement Walking, cycling or being on your feet more. The easiest to sustain — a short walk after meals is a gentle place to start.
  • Strength work Building muscle improves insulin sensitivity. Bodyweight exercises at home count — no gym needed to begin.
  • Yoga & mind-body Yoga and similar practices can support stress and wellbeing, which matter for PCOS alongside the physical benefits.
  • Rest & recovery Sleep and rest are part of the picture too — pushing too hard too soon is the main reason routines don't last.

A 15-minute walk after dinner is often easier to keep up than a sudden hour at the gym — and small, repeatable habits tend to stick. Progress in PCOS is rarely about doing the most; it's about doing something regularly. Movement also helps mood and sleep, which matters as much as any physical change.

Full guide PCOS, weight and movement — a practical, sustainable approach

If you have other health conditions or haven't exercised in a while, it's worth checking with a doctor before starting something new. You can also check your BMI as one starting point to discuss.

Fertility & pregnancy

PCOS and fertility

A PCOS diagnosis can feel worrying if you hope to have children. But for most people it doesn't mean you can't conceive — it often just means ovulation needs a little support.

Yes — most women with PCOS can get pregnant. PCOS can make conceiving take longer because ovulation is irregular, but it's one of the most treatable causes of difficulty conceiving. Many people conceive naturally; others do so with treatments that encourage ovulation, and assisted options exist if those aren't enough. It can take time, and outcomes vary — but for most, the outlook is hopeful.

  • The ovulation link

    PCOS can disrupt the release of an egg, so cycles are irregular. This — not the ovaries themselves — is usually what affects conceiving.

  • Lifestyle first

    For some, steadier routines and supported lifestyle changes are enough to make ovulation more regular and improve the chance of conceiving.

  • Treatments to help ovulation

    If needed, doctors can use medications that encourage ovulation — often a very effective next step. A specialist will guide what suits you.

  • Further support

    Where more help is needed, assisted options such as IUI or IVF are available. Many paths to parenthood remain open with PCOS.

It's completely normal to feel anxious about fertility with PCOS. The reassuring reality is that PCOS is among the more treatable reasons for difficulty conceiving — and most people who want to have children eventually can. If you've been trying for a while, seeing a doctor early opens up the most options.

Fertility care is highly individual. The right path depends on your age, how long you've been trying, and your overall health — a doctor or fertility specialist can guide you. You may also find our AMH test guide useful background.

Long-term health

PCOS and your long-term health

PCOS can raise the risk of a few longer-term health conditions — but "raised risk" is not "certainty." These risks are among the most manageable in medicine, and there's a lot you and your doctor can do to lower them.

Because PCOS affects how the body handles insulin, it can raise the long-term risk of conditions like type 2 diabetes, high blood pressure and heart health issues, and sleep apnea. The reassuring part: these risks are largely reducible. Regular check-ups catch changes early, and the same steps that help PCOS day to day — supported lifestyle changes, monitoring and treatment where needed — also protect long-term health.

  • Type 2 diabetes

    Insulin resistance raises the risk of higher blood sugar over time.

    What helpsRegular blood-sugar checks, supported lifestyle changes, and treatment where needed substantially lower this risk.

  • Heart & blood pressure

    PCOS can be linked with higher blood pressure and cholesterol over the years.

    What helpsRoutine checks of blood pressure and cholesterol, plus activity and a balanced diet, keep heart health on track.

  • Sleep apnea

    Disturbed breathing in sleep is more common with PCOS, and can worsen tiredness.

    What helpsIt's very treatable — telling your doctor about poor sleep or daytime tiredness means it can be assessed and managed.

  • Mood & wellbeing

    Low mood and anxiety are more common with PCOS — and are health matters, not weakness.

    What helpsThey're treatable. Talking to a doctor opens up support, and managing PCOS often helps mood too.

The bigger picture is hopeful

None of these is a foregone conclusion. The single most useful thing is staying connected to a doctor for regular check-ups, so any changes are spotted and managed early. People who manage their PCOS well often keep these risks low and live full, healthy lives.

Full guide PCOS complications in detail — the risks, the evidence, and how each is managed

PCOS shares risks with conditions like type 2 diabetes — so the prevention steps overlap, and looking after one often helps the other.

Living well

Can PCOS be managed?

It's one of the most common questions after a diagnosis — and the honest answer is reassuring.

In short

Yes — PCOS is highly manageable. It's usually lifelong and can't be cured, but the great majority of people with PCOS live healthy, active lives by managing it.

Managing PCOS isn't about a perfect routine or dramatic change. It's about a handful of steady habits, regular check-ins with a doctor, and treating the parts that affect you most. The condition often becomes easier to live with once you understand your own pattern — and small, repeatable steps tend to do more than big ones you can't sustain.

  • Steady routines

    Regular meals, movement and sleep help insulin and hormones stay steadier than any one "perfect" plan.

  • Know your pattern

    Tracking your cycle and symptoms helps you and your doctor see what's working and adjust over time.

  • Mind your wellbeing

    PCOS can affect mood and self-image. Looking after mental health is part of managing the condition, not separate from it.

  • Stay in touch with care

    Regular check-ups keep treatment matched to your needs and catch any changes early — the single most useful habit.

A common mistake is easing off once things improve — but PCOS responds best to steady, ongoing care rather than short bursts. Many people find that a few habits they can genuinely keep up make far more difference over the years than any strict plan they abandon after a month. You don't have to do everything at once.

Common questions

PCOS — frequently asked questions

Quick, plain-language answers to the questions people most often ask about PCOS.

What causes PCOS?

The exact cause of PCOS isn't fully known. It's understood as a mix of genetic and metabolic factors — a family history, the way the body handles insulin, and hormone balance all play a part, and they interact differently in each person. More on causes.

Can PCOS be cured?

PCOS can't usually be cured, but it is highly manageable. It's typically a lifelong condition, yet most people control its features well through supported lifestyle changes, medication where helpful, and regular check-ups — and live healthy, active lives.

Can PCOS cause infertility?

PCOS can make conceiving take longer because ovulation is irregular, but it's one of the most treatable causes of difficulty conceiving. Most women with PCOS can get pregnant — many naturally, others with treatments that encourage ovulation. PCOS & fertility.

Does losing weight help PCOS?

For some people, supported lifestyle changes can ease PCOS features and help cycles become more regular. But PCOS also affects people at a healthy weight, and weight isn't the cause. The focus is sustainable habits, not a number on the scale.

Which foods should I avoid with PCOS?

No food is strictly off-limits with PCOS. It helps to keep sugary drinks, sweets and large portions of refined carbs in check, and to build balanced meals with fibre, protein and healthy fats. Balance matters more than restriction. PCOS diet guide.

Is PCOS genetic?

PCOS often runs in families, so genetics play a part — if your mother or sister has it, your likelihood is higher. It's thought to involve several genes rather than one, alongside metabolic and environmental factors.

Can PCOS increase diabetes risk?

Yes — because PCOS often involves insulin resistance, it can raise the long-term risk of type 2 diabetes. The reassuring part is that this risk is largely reducible through regular blood-sugar checks, lifestyle changes, and treatment where needed. About type 2 diabetes.

Can women with PCOS get pregnant?

Yes, most women with PCOS can get pregnant. The main hurdle is irregular ovulation, which is often very treatable. Many conceive naturally; others with medications that encourage ovulation, and assisted options exist if needed.

Which doctor treats PCOS?

PCOS is usually managed by a gynaecologist or an endocrinologist (a hormone specialist), often alongside your general doctor. If fertility is the focus, a fertility specialist may be involved. Your GP is a good first point of contact.

What tests diagnose PCOS?

There's no single test. PCOS is diagnosed using the Rotterdam criteria — two of three features — after ruling out other conditions. A doctor combines your history, blood tests for hormones, and sometimes an ultrasound. How PCOS is diagnosed.

Related conditions

Conditions linked to PCOS

Because PCOS affects hormones and metabolism, it shares ground with a few other conditions. Knowing the links helps you and your doctor keep an eye on the right things — and the steps that help one often help the others.

Being linked to these conditions doesn't mean you'll develop them. It's a reason to stay in regular contact with your doctor, who can check for them early — and the everyday habits that help PCOS protect against these too.
