It was renamed PMOS in May 2026, and the new name finally says the important part out loud: this is a hormonal and metabolic condition, not a problem with cysts. Diagnosis done properly, treatment matched to what you actually want, and follow-up that continues long after your family is complete.
A condition in which the ovaries do not release an egg reliably, androgen levels run higher than they should, and the body handles insulin less well than it should. Those three things drive everything else — the irregular periods, the acne and hair, and the long-term risks.
It is not a cyst problem, it is not caused by anything you did, and it is not only a fertility problem. It is also not curable — but it is one of the most controllable conditions in gynaecology, which is a very different sentence.
Confirm the diagnosis properly rather than accepting it from a scan report. Check sugar, cholesterol and blood pressure. Then treat what is actually bothering you, and keep the lining of the uterus protected while you do.
Three names are in circulation in India and nobody explains how they relate. Here is the whole of it.
“Polycystic ovarian disease”. Universally used in India, and not a recognised medical term anywhere. There is no such thing as a milder PCOD and a more serious PCOS — that distinction was invented in clinics and it has no basis. If your report says PCOD, it means PCOS.
“Polycystic ovary syndrome”. The name in use since the 1930s and the one on every prescription, lab form and insurance record you will see for years to come. It is the name this page is written under, because it is the name you searched for.
Polyendocrine Metabolic Ovarian Syndrome — the new name, agreed in May 2026. Polyendocrine for the several hormone systems involved, Metabolic for the effects on weight and blood sugar, Ovarian for where it shows itself.
The change came out of a 14-year international consensus led from Monash University, with more than 22,000 survey responses from women with the condition and over 50 patient and professional organisations involved. The final panel vote was 88 of 90 in favour. The two names that lost were “endocrine metabolic ovulatory syndrome” and “ovulatory metabolic endocrine syndrome”.
Nobody needs to be re-diagnosed and no treatment changes because of the new name. If you were told you have PCOS, you have PMOS, and it is the same condition with the same plan.
There is a three-year transition, with full adoption expected in the 2028 international guideline. Expect to keep seeing “PCOS” on lab forms, prescriptions, hospital records and insurance paperwork for a long time yet. That is normal, not an error.
Two of the ninety panel members voted against, both of them patient-advocacy leaders, on the grounds that it is an enormous rebranding exercise to change one letter. It is a fair objection and worth knowing that it was made.
What the new name does change is the conversation. A woman told she has “cysts on her ovaries” hears a gynaecological problem that ends when she has had her children. A woman told she has a polyendocrine metabolic syndrome hears something she will be managing at forty-five. The second one is accurate, and it is the reason the rest of this page reads the way it does.
This is the single most frightening sentence a woman with PCOS reads on her scan report, and it describes something entirely harmless.
Every month a group of small follicles begins to grow in the ovary, one becomes dominant, releases an egg, and the rest fade away. In PCOS the hormonal environment never lets one pull ahead. The result is an ovary holding a ring of small, immature follicles that were meant to disappear and did not. That is what the radiologist is counting, and the diagnostic threshold is 20 or more follicles in at least one ovary.
They are not tumours, they do not need removing, they do not turn into anything, and they are not the ovarian cysts described on our ovarian cyst page, which are a completely different problem. The international group that renamed the condition put it flatly: the research confirms there is no increase in abnormal cysts on the ovary in this condition at all. The name was wrong for ninety years.
In an adult, PCOS is diagnosed when any two of these three are present — and, importantly, when the conditions that imitate it have been excluded.
Cycles that are long, irregular, infrequent or absent. In practice, cycles consistently longer than 35 days, or fewer than eight periods in a year, or a gap of more than three months.
Either clinical — unwanted hair on the face, chin, chest or abdomen, persistent acne past the teens, hair thinning at the crown — or measured on a blood test. Either counts; you do not need both.
Twenty or more follicles in at least one ovary on a scan or a raised AMH level on a blood test. The 2023 international guideline accepts AMH as a genuine alternative to the scan in adults, which is new and not yet widely known.
Two cautions that change who gets diagnosed. First, in anyone within eight years of her first period, neither the scan nor AMH should be used at all — multi-follicular ovaries are simply normal at that age, and a great many teenagers are labelled on the strength of a scan that means nothing. In adolescents, both irregular cycles and androgen excess must be present. Second, thyroid disease, a raised prolactin, and rarer adrenal conditions can produce the same picture and are ruled out with blood tests before the label is accepted. Our companion article on the seven signs a doctor actually looks for goes through each of them one at a time.
PCOS is usually presented as a periods-and-fertility problem. The evidence describes something considerably wider, and most of it plays out in decades rather than months.
Insulin resistance sits underneath this condition whether you are overweight or not, and the risk of impaired glucose tolerance and type 2 diabetes is raised well before any of it becomes obvious. This is the single strongest reason to keep being followed up.
Pooled across 22 studies and 5,507 women with PCOS, 24% developed gestational diabetes. It is one of the reasons a pregnancy here is followed a little more closely, and why sugars are checked before conception rather than at 24 weeks.
The guideline asks for a lipid profile at diagnosis regardless of age and BMI, and blood pressure annually. Not because something is wrong today, but because this is the group in which it drifts quietly.
Without ovulation there is no progesterone, so the lining keeps thickening and is never properly shed. Pooled odds of endometrial cancer are 2.79 overall and 4.05 in women under 54. Read that alongside the next paragraph before it frightens you.
Significantly commoner in PCOS, and independent of body weight. Snoring, waking unrefreshed and daytime sleepiness are worth mentioning rather than dismissing, because treating it improves the metabolic side as well.
Moderate to severe depressive and anxiety symptoms are common enough that the international guideline asks doctors to screen for them routinely. This is not a side issue and it is not you being dramatic about acne.
Put the cancer number in proportion. A relative risk of four sounds terrifying and the absolute risk stays small — endometrial cancer peaks at roughly 90 cases per 100,000 women a year, around 0.09%, and that peak is at seventy. The authors of that analysis said so themselves. What it justifies is not fear; it is making sure the lining gets shed regularly, which is straightforward. If you have had a scan report mentioning a thick lining, our page on what thickened endometrium means covers that, and endometrial hyperplasia covers what happens if a biopsy has already been done.
Taken from the 2023 international evidence-based guideline. If nobody has done these, that is the gap worth closing first.
Blood glucose status, a full lipid profile and blood pressure. The guideline is explicit that the lipid profile is done regardless of age and BMI — being slim does not exempt you, and lean PCOS is a real thing that gets under-investigated precisely because the woman does not look the part.
A 75 g oral glucose tolerance test is the most accurate way to assess this, more so than HbA1c alone. It is done at the clinic. Which test is appropriate for you depends on your risk factors, and it is worth asking rather than assuming a fasting sugar has settled the question.
Repeat glucose testing on that interval, judged by your own risk factors — family history, weight change, previous gestational diabetes. Blood pressure yearly. This is the part that stops happening once the periods are sorted out, and it is the part that matters longest.
Blood pressure and glucose are checked again when you are planning a pregnancy or starting fertility treatment. Given the 24% figure above, sugars in this group are looked at early rather than left to the routine schedule.
There is no single PCOS treatment, because there is no single PCOS problem. The plan is built around what you want fixed and what you want next.
Unglamorous, and genuinely the most powerful single lever where weight is a factor. A modest reduction restores spontaneous ovulation in a meaningful proportion of women and improves how well everything else works. It is offered as a treatment here, not as a rebuke.
First-line for irregular cycles and for the hair and acne, per the international guideline, with a preference for lower-dose preparations. No specific brand is recommended over another. It regulates bleeding and protects the lining at the same time.
If the pill does not suit you, cyclical progestogen or a hormonal IUD does the same job. The coil is fitted here at the clinic as an outpatient procedure, lasts years, and is the option most women are never offered.
Recommended primarily for the metabolic side rather than as a fertility drug, and the guideline notes it has greater efficacy than inositol. Useful where insulin resistance is present. Not routinely continued in pregnancy.
Anti-androgens have a limited role and are for when other treatments have not worked or cannot be used — always with reliable contraception alongside. Laser reduces hair effectively in some women. Expect months, not weeks; hair responds slowly whatever is used.
Letrozole is first-line, ahead of clomiphene, and the difference in live births is not small. Our full page on ovulation induction sets out the evidence, the monitoring and when the plan should change.
The most heavily marketed PCOS supplement in India. The international guideline's assessment is that it offers limited clinical benefits, and that metformin is more effective. It is not dangerous and it is not the answer it is sold as.
Nothing detoxifies an ovary. Where a product has been tested against a placebo it has generally not outperformed one. Money spent here is money not spent on the things that do work, which is the real cost.
It will not. Cycles often do improve after a pregnancy and the underlying condition is unchanged. Advice of this kind is the reason so many women arrive at forty having never had their blood sugar checked.
Cycle pattern, hair and skin, weight history, family history of diabetes, and what you actually want dealt with. Blood tests — hormones, thyroid, prolactin, glucose and lipids — are taken at the clinic.
All scans are arranged by referral — we do not run imaging at the clinic — and the images and report are then gone through with you here. In an adult with clearly irregular cycles and obvious androgen excess, the diagnosis is often already made without one.
Treatment matched to your priority, whether that is regular bleeding, skin and hair, a pregnancy, or protecting the lining while you decide. Mirena insertion, if that is the route chosen, is done at the clinic. Hysteroscopy, laparoscopy and ovarian drilling are hospital procedures.
If you were diagnosed years ago, put on the pill, and never seen again — that is the commonest story in this condition, and a review is worth booking even if nothing feels wrong. The point of the follow-up is to catch things while they are still numbers on a page.

Real stories from women whose lives we've had the privilege to be part of
"I had been struggling with PCOS for years: irregular periods, weight gain, constant fatigue. Dr. Anam took the time to truly understand my case. Within a few months my cycles became regular and I finally felt healthy again."
"The most compassionate doctor I have ever met. She never makes you feel rushed, always listens completely, and explains everything clearly. My whole family now comes to Dr. Anam."
"After two miscarriages I was terrified to try again. Dr. Anam identified the issue, treated it, and supported me through my entire third pregnancy. I now have a beautiful daughter, something I wasn't sure would ever happen."
"Dr. Anam handled my high-risk pregnancy with such care and expertise. Every visit felt reassuring. She explained everything clearly and was always available when I had concerns. My baby and I are both healthy and happy!"
"I visited Dr. Anam for recurrent UTIs I had suffered with for years. She finally found the root cause and gave me a long-term solution. Eight months with no recurrence."
"I was very nervous but Dr. Anam made the entire journey so comfortable. She is patient, thorough, and incredibly warm. I wouldn't trust anyone else with something so precious."

Polyendocrine Metabolic Ovarian Syndrome, shortened to PMOS. The change was announced on 12 May 2026 after a 14-year international consensus process. Polyendocrine refers to the several hormone systems involved, metabolic to the effects on weight and blood sugar, and ovarian to where the condition shows itself.
Because the old name described the one thing about the condition that is not true. It reduced a complex, lifelong hormonal and metabolic disorder to a misunderstanding about cysts, and the research confirms there is no increase in abnormal cysts on the ovary at all. The name led to missed diagnoses and to treatment that stopped at the ovaries.
No. Your diagnosis has not changed, your treatment does not change, and no new test is needed. If you were told you have PCOS, you have PMOS. It is the same condition under a more accurate name.
An international consensus process led from Monash University, involving more than 50 patient and professional organisations including the Endocrine Society and the AE-PCOS Society, and drawing on over 22,000 survey responses from women with the condition collected in 2017, 2023 and 2025. The final panel vote was 88 of 90 in favour.
No, and it is worth knowing that. Two of the ninety panel members voted against, both patient-advocacy leaders, arguing that it is a very large rebranding effort to change a single letter and that the new name still leaves some questions open. The objection is a reasonable one.
Slowly. There is a three-year transition, with full adoption expected in the 2028 international guideline update. You should expect to keep seeing PCOS on lab forms, prescriptions, hospital records and insurance paperwork for years yet. Both names refer to the same condition.
Not as part of the renaming. Diagnosis still rests on two of three features in an adult. Whether the criteria themselves should change is a separate question that remains under review internationally.
There is none. PCOD is not a recognised medical term anywhere in the world; it is Indian usage that stuck. The idea that PCOD is a milder version and PCOS the serious one was invented in clinics and has no basis in any guideline. If your report says PCOD, it means PCOS.
Not on its own. Polycystic-appearing ovaries on a scan are one of three possible features, and at least two are needed for the diagnosis. Plenty of women have that appearance with entirely normal cycles and normal hormones and do not have the condition.
They are not cysts. They are small follicles that started to grow and never matured, which is exactly what happens when no egg is released. They are not tumours, they do not need removing, they do not turn into anything, and they are unrelated to the ovarian cysts that sometimes need surgery.
Twenty or more in at least one ovary, on modern equipment. Counting fewer than that does not support the diagnosis, and the count alone never makes it.
The appearance often improves once cycles become regular, because follicles are being used rather than accumulating. But the aim of treatment is not to clear the scan picture, and a scan is not the way to judge whether treatment is working.
In an adult, by any two of three: irregular or absent ovulation; excess androgen, either visible as unwanted hair, persistent acne or scalp hair thinning, or measured on a blood test; and polycystic ovaries on a scan or a raised AMH level. Conditions that imitate it, particularly thyroid disease and raised prolactin, are excluded first.
In adults, yes. The 2023 international guideline accepts a raised AMH as an alternative to the ultrasound for the third criterion. This is a genuine change and is not yet widely known. It does not apply to adolescents.
It deserves questioning. Within eight years of a girl's first period, neither the ultrasound nor AMH should be used for diagnosis, because multi-follicular ovaries are simply normal at that age. In adolescents both irregular cycles and androgen excess must be present, and irregular cycles alone in the first year or two after menarche are usually just an immature system settling.
An underactive thyroid, a raised prolactin level, and less commonly adrenal conditions such as non-classical congenital adrenal hyperplasia. All are checked with blood tests. Some are corrected by treating the cause rather than by treating PCOS at all.
Between 10 and 13% of women worldwide using the current criteria. Indian estimates vary widely by region, and a study of over a thousand college students in Delhi NCR found 17.4% - with around three in ten of those cases picked up during the study rather than already known. Under-diagnosis is the norm, not the exception.
Yes, and it is regularly missed for exactly that reason. Insulin resistance is present in lean women with PCOS too. The guideline asks for a lipid profile at diagnosis regardless of age and BMI, which exists precisely so that slim women are not skipped.
Both directions are real, which is why it is so hard to escape. Insulin resistance makes weight easier to gain and harder to lose; extra weight worsens insulin resistance and androgen levels. That is a loop, not a character failing, and it is the reason a modest weight reduction has an effect out of proportion to its size.
Less than people expect. A modest reduction restores spontaneous ovulation in a meaningful proportion of women with PCOS and improves the response to treatment in those who still need it. The target is not a dress size.
Yes. Impaired fasting glucose, impaired glucose tolerance and type 2 diabetes are all commoner, independent of weight. This is why the guideline asks for glucose testing at diagnosis in everyone with the condition, and again every one to three years depending on your other risk factors.
The 75 g oral glucose tolerance test is the most accurate assessment in PCOS - more so than HbA1c alone. It is done at the clinic. A single normal fasting sugar is not a complete answer to this question.
The risk is meaningfully higher. Pooled across 22 studies and 5,507 women with PCOS, 24% developed gestational diabetes. It is a reason to check sugars before conception rather than waiting for the routine test.
There is an increased risk of cardiovascular disease. Nothing about that is inevitable, and it is the reason blood pressure is checked annually and a lipid profile is done at diagnosis rather than when symptoms appear.
It raises the risk of cancer of the uterine lining, because a lining that is never shed keeps thickening. Pooled odds are 2.79 overall and 4.05 in women under 54. Set against an absolute incidence that peaks at roughly 90 cases per 100,000 women a year, that is a reason for regular bleeds rather than for fear - and regular bleeds are easy to arrange.
The principle is that the lining should not be left unshed for long stretches. Cycles that come only every few months, or not at all, are the pattern that needs a plan - usually the pill, cyclical progestogen or a hormonal coil. What is right for you is decided at the consultation, not by a general rule.
Mention it if you snore, wake unrefreshed or are sleepy through the day. Sleep apnoea is significantly commoner in PCOS and, notably, independently of body weight. Treating it improves the metabolic picture as well as the sleep.
It is common enough that the international guideline asks doctors to screen for depression and anxiety in everyone with the condition. Moderate to severe symptoms are frequent. Raising it is not a distraction from the medical conversation; it is part of it.
No, and anyone promising a cure is selling something. It can be controlled very effectively, which is a different and more useful statement. Symptoms return when treatment stops because the underlying condition is still there.
For irregular cycles and for the hair and acne, the combined oral contraceptive pill, with a preference for lower-dose preparations. No particular brand is recommended over another. Where weight is a factor, lifestyle change runs alongside it rather than instead of it.
Cyclical progestogen tablets, or a hormonal IUD, which does the same job for years without a daily tablet and usually makes periods much lighter. The coil is fitted at the clinic as an outpatient procedure. It is the option most women with PCOS are never offered.
It is recommended primarily for the metabolic features rather than as a fertility drug, and it is most useful where insulin resistance is present. The guideline notes it has greater efficacy than inositol. It is not routinely continued into pregnancy.
The international guideline's conclusion is that inositol offers limited clinical benefits in PCOS, and that metformin is more effective. It is heavily marketed in India. It is not harmful; it is simply not the answer it is sold as.
Anti-androgen medication has a limited role and is used where other treatments have not worked or cannot be used, always with reliable contraception alongside because of the risk to a pregnancy. Laser reduces hair effectively in some women. Either way, expect months rather than weeks - hair responds slowly to everything.
Usually, with time. Both respond to lowering androgen levels, and the pill is the usual route. Skin tends to improve before hair, and scalp hair is the slowest of all to recover.
No. It is the commonest cause of ovulatory infertility and it is also among the most treatable. The problem is that eggs are not being released, not that they are absent - in fact the ovary usually holds plenty.
Letrozole is first-line, ahead of clomiphene, and the difference in live births is not small. If tablets do not work the options are metformin alongside them, gonadotropin injections, laparoscopic ovarian drilling, or IVF. Our ovulation induction page sets out the evidence and the monitoring.
Getting glucose, weight where relevant, thyroid and folic acid in order before conception is worth doing and makes the pregnancy safer. It is not a reason to postpone indefinitely, and age still matters more than anything else.
Cycles often become more regular for a while, which is why the myth persists. The condition itself does not go anywhere, and the metabolic side continues to need attention long after your family is complete.
No. All scans are arranged by referral - we do not run imaging at the clinic - and the report and images are then gone through with you here. Consultation, blood tests including the glucose tolerance test, prescribing and follow-up all happen at the clinic.
Consultation, the full blood work-up, prescribing and monitoring of all the medical treatments including ovulation induction, and Mirena insertion and removal as an outpatient procedure. Hysteroscopy, laparoscopy and ovarian drilling are hospital procedures.
Any previous scan reports and blood tests, a rough record of your last several cycle dates, and a list of anything you are already taking, supplements included. If you have a family history of diabetes or thyroid disease, that is worth knowing too.
Yes, and it is the commonest version of this story. Being put on the pill and discharged leaves the metabolic side unexamined for years. A review that checks glucose, lipids and blood pressure is worth booking even when nothing feels wrong.
Consultation, blood tests and follow-up at either location. Open 7 days a week, including Sundays.
