PCOS Myths: Do You Need Cysts to Have It, and Does It Always Affect Fertility?

Two friends compare notes over coffee. One has just been told her ovaries “look polycystic” on an ultrasound, but her doctor says she probably does not have PCOS. The other has never had a scan at all, yet her clinician is confident she does. Both leave confused, and both go home to search engines full of contradictory advice.

That confusion is not their fault. Polycystic ovary syndrome has a misleading name, three different ways of being diagnosed, and a reputation shaped more by forums than by endocrinology. Of all the pcos myths in circulation, two do the most damage: that you must have cysts to have it, and that it means you cannot have children.

Neither is true. What follows is a careful walk through what the condition is, how it is actually identified, and where the evidence lands on fertility, weight, diagnosis and treatment, with the decisions left where they belong, with you and your care team.

What PCOS actually is, and why the name misleads

Polycystic ovary syndrome is a hormonal condition, not an ovarian one. The ovary is where its most visible sign shows up, but the underlying problem sits in the conversation between the brain, the pancreas and the ovaries.

In a typical cycle, the pituitary gland at the base of the brain releases signals that coax one follicle (a fluid-filled sac holding an immature egg) to mature and release its egg. In PCOS, that process stalls. The ovaries produce more androgens than usual (androgens are a group of hormones, including testosterone, that everyone makes in small amounts), and many people also have insulin resistance, meaning their cells respond sluggishly to insulin, so the pancreas makes more of it. Higher insulin nudges the ovaries to make still more androgen. The result is a loop: follicles start developing, then pause part-way, and ovulation becomes irregular or stops.

Those paused follicles are what an ultrasound picks up. According to the NHS, they are harmless, immature follicles up to about 8 millimeters across, not true cysts in the sense most people imagine. A more accurate name would describe excess androgen and irregular ovulation, which is why some researchers have argued for renaming the condition altogether.

How common is it? The World Health Organization estimates that PCOS affects roughly 8 to 13 percent of women of reproductive age, and that up to 70 percent of those affected remain undiagnosed. The NHS puts the figure at about 1 in 10 women in the UK, adding that more than half have no symptoms at all. Hold on to that last detail. A condition that is silent in half the people who have it is a condition that will always be surrounded by myths.

PCOS myths, part one: do you need cysts to have PCOS?

You do not. This is the most persistent of the pcos myths, and it flows directly from the name.

Diagnosis in most of the world uses what are known as the Rotterdam criteria, described by the NHS, Mayo Clinic and others: a person needs any two of three features. The first is irregular or infrequent periods, a sign that ovulation is not happening regularly. The second is evidence of high androgens, either on a blood test or through physical signs such as excess facial and body hair or persistent acne. The third is the polycystic appearance of the ovaries on ultrasound.

Because only two of three are required, someone with irregular cycles and clearly raised androgens meets the criteria without a scan ever being performed. The NHS notes that an ultrasound is not needed for diagnosis when the other two features are present. This is the situation of the second friend in the opening scene, and it is entirely legitimate medicine.

The reverse is also true, and it matters just as much. A polycystic-looking ovary on its own is not PCOS. Mayo Clinic points out that ovaries can appear polycystic in people who ovulate normally and have normal hormone levels, particularly in younger women. In that case the finding is simply an ultrasound observation, not a diagnosis, and it should not by itself trigger treatment.

So the honest phrasing is this: the polycystic appearance is one possible clue among three. It is neither necessary nor sufficient. When someone searches for “pcos without cysts,” the answer is that this is not an unusual variant. It is one of the recognized ways the condition presents.

How is PCOS diagnosed? The three criteria and what each one means

Diagnosis is a process of assembling evidence and, crucially, ruling other things out. Thyroid disorders, raised prolactin (a pituitary hormone) and certain adrenal conditions can all mimic PCOS, so clinicians check for these before settling on the label. The table below summarizes the three Rotterdam features as described by the NHS, Mayo Clinic and Johns Hopkins Medicine.

Feature	What it reflects	How it is usually assessed	Common misunderstanding
Irregular or absent ovulation	Follicles are not maturing and releasing eggs on schedule	Menstrual history; sometimes blood tests timed to the cycle	“My cycles are only slightly off, so it can’t be PCOS” (timing varies widely)
Excess androgens	Ovaries and sometimes adrenal glands producing more testosterone-type hormones	Blood test for androgens, or physical signs such as excess hair growth or acne	“My testosterone is normal, so I don’t have it” (physical signs can count even when the blood test is borderline)
Polycystic ovary appearance	Many small, stalled follicles visible on ultrasound	Pelvic ultrasound, often transvaginal	“Cysts were seen, so I have PCOS” (appearance alone is not diagnostic)

Two of the three, with other causes excluded, is the standard. Notice how much of this rests on history and examination rather than technology. A careful conversation about cycle length, skin and hair changes, and family history often carries more diagnostic weight than the scan.

One further nuance: because the criteria can be met in different combinations, clinicians sometimes describe PCOS “phenotypes,” meaning subgroups defined by which features are present. Someone with all three tends to have more pronounced metabolic features than someone with a polycystic appearance and irregular cycles but normal androgens. This is part of why two people with the same diagnosis can have very different experiences, and why a diagnosis should come with a discussion about which features apply to you.

Does PCOS always affect fertility?

No, and this deserves to be said plainly, because the assumption causes real distress. PCOS is, according to the WHO, a leading cause of infertility related to ovulation. That is a population-level statement. It does not translate into a verdict for any one person.

The mechanism is straightforward. Pregnancy requires an egg to be released, and PCOS makes ovulation irregular. Someone who ovulates eight times a year has fewer opportunities to conceive than someone who ovulates twelve. Someone who rarely ovulates has fewer still. But irregular is not the same as never. Mayo Clinic and the NHS both describe people with PCOS conceiving naturally, sometimes after unpredictably long stretches, and note that the condition’s impact on fertility ranges from negligible to significant.

Where ovulation is the barrier, it is also one of the more addressable barriers in reproductive medicine. The NHS describes a stepwise approach: lifestyle measures where relevant, then medicines that prompt the ovary to release an egg. Two generic medicines are widely used for this. Letrozole belongs to a class called aromatase inhibitors and works by briefly lowering estrogen so the brain sends a stronger signal to the ovary. Clomiphene works on estrogen receptors in the brain to a similar end. Metformin, a diabetes medicine, is sometimes used to improve the body’s response to insulin, which can indirectly support ovulation. If these do not help, options include a keyhole procedure on the ovaries or assisted reproduction such as IVF.

None of this is a promise. Response varies, other fertility factors can coexist, and the right sequence is a decision for a fertility specialist who knows your history. What the evidence does support is the opposite of the myth: a PCOS diagnosis is a reason to plan, not a reason to assume.

Is PCOS overdiagnosed, underdiagnosed, or both? Why PCOS is controversial

Ask a room of endocrinologists whether PCOS is overdiagnosed and you will get an argument. Ask whether it is underdiagnosed and you will get the same argument from the other side. Both positions have evidence behind them, which is exactly why the condition attracts controversy.

The case for underdiagnosis rests on numbers from the WHO: up to 70 percent of affected women worldwide have never been told. Symptoms get dismissed as cosmetic, irregular periods are masked by hormonal contraception, and many people spend years cycling through dermatologists and dietitians before anyone connects the dots.

The case for overdiagnosis centers on adolescents and on the ultrasound criterion. Teenagers commonly have irregular cycles and ovaries with many follicles in the first years after their first period, simply because the reproductive system is still maturing. Mayo Clinic and the NHS both caution that a polycystic appearance is common in young women who do not have the syndrome. Labeling a sixteen-year-old with a lifelong condition on the basis of a scan risks unnecessary worry and unnecessary treatment. Current international practice, reflected in NHS guidance, therefore leans toward not relying on ultrasound in adolescents and toward waiting to confirm the diagnosis as cycles settle.

The deeper controversy is definitional. Because two of three features suffice, the diagnosis captures a wide spectrum, from someone with severe insulin resistance and no ovulation to someone with a slightly irregular cycle and mild acne. Some researchers argue that lumping these together under one label obscures meaningful differences in long-term risk. Others argue the umbrella term still serves patients well by prompting metabolic screening they would otherwise never receive.

The honest summary: the diagnosis is real and useful, its borders are fuzzy, and a good clinician will tell you which part of the spectrum you sit on.

What are uncommon signs of PCOS that get overlooked?

Most people can name the headline features: irregular periods, acne, unwanted hair. The less familiar ones are worth knowing about, not so you can diagnose yourself, but so you can raise them in an appointment where they might otherwise never come up.

Hair can thin as well as thicken. Androgen excess that drives coarse hair on the face or chest can also cause hair loss at the crown and temples in a pattern more usually associated with men. Mayo Clinic lists this among the recognized features, and it is frequently attributed to stress or genetics without anyone checking hormones.

Skin changes beyond acne are another clue. Acanthosis nigricans is the medical term for velvety, darkened patches of skin, typically in the neck folds, armpits or groin, and it is a marker of insulin resistance. Small skin tags in the same areas can accompany it. Cleveland Clinic and Mayo Clinic both describe these as features clinicians look for.

Sleep is affected more often than people expect. Obstructive sleep apnea, where breathing repeatedly pauses during sleep, is more common in people with PCOS, particularly when weight is higher, according to Mayo Clinic. Loud snoring and daytime exhaustion are easy to attribute to a busy life.

Mood matters too. The NHS and Mayo Clinic note higher rates of depression and anxiety among people with PCOS. Whether this stems from hormones, from living with visible symptoms, or from both is not fully settled, but it is real, and it belongs in the conversation with your care team.

Finally, the quietest sign of all: none. As the NHS notes, more than half of people with polycystic ovaries have no symptoms. Some learn of the condition only when trying to conceive, or when a routine blood test shows raised blood sugar. That silence is a strong argument against assuming you would know if you had it.

PCOS myths about weight: is it a condition of larger bodies, and does losing weight fix it?

Two myths sit on either side of this topic, and both hurt people. The first says PCOS only happens to people in larger bodies. The second says weight loss is the fix.

On the first: PCOS occurs across the full range of body sizes. Mayo Clinic and Johns Hopkins Medicine describe people at lower weights presenting with the same irregular cycles and androgen excess, sometimes referred to informally as “lean PCOS.” These individuals are often diagnosed later precisely because their appearance does not fit the stereotype. Insulin resistance can still be present, and the long-term metabolic considerations still apply, though they may be less pronounced.

On the second: weight and PCOS interact in a loop, not a straight line. Insulin resistance makes weight gain easier and weight loss harder; higher weight, in turn, worsens insulin resistance and androgen production. The NHS reports that in people who carry excess weight, losing a modest proportion of body weight can improve cycle regularity and symptoms. That is genuinely useful information, and it is why lifestyle measures sit at the foundation of most guidelines.

But “can improve” is not “resolves.” Weight loss does not switch off the underlying hormonal pattern, does not help everyone, and is not relevant advice for someone already at a lower weight. Telling a patient to simply lose weight, without acknowledging that the condition itself makes that harder, is both unkind and incomplete medicine. Respectful care starts from the body the person actually has.

The evidence-first position: weight is one modifiable factor among several, it matters more for some phenotypes than others, and it is never the whole story. Anyone who has been told otherwise deserved a fuller explanation.

What causes PCOS? Sugar, stress, birth control and the insulin question

The short answer is that no one knows precisely, and that uncertainty has created a vacuum that myths rush to fill.

What the evidence does support, according to the NIH’s Eunice Kennedy Shriver National Institute of Child Health and Human Development and Mayo Clinic, is a combination of inherited tendency and hormonal environment. PCOS clusters in families; having a mother or sister with the condition raises the likelihood. Genes appear to influence how the ovaries respond to insulin and how much androgen they produce. Some research points to hormone exposure before birth as a possible contributor, though this remains under investigation.

Insulin resistance is central for many, though not all, people with PCOS. When cells respond weakly to insulin, the pancreas compensates by producing more. Elevated insulin acts on the ovaries to increase androgen output and reduces a liver protein that normally binds testosterone, leaving more of it free and active. This is the mechanism linking PCOS to type 2 diabetes risk, and it explains why medicines that improve insulin sensitivity are sometimes part of treatment.

Now the myths. Eating sugar does not cause PCOS, although a diet high in refined carbohydrates can worsen insulin resistance in someone who already has it. Stress does not cause PCOS, though it can disrupt cycles on its own. Hormonal contraception does not cause PCOS; it can mask irregular cycles, so symptoms sometimes surface after stopping it, which people mistake for a new condition. Nothing you did as a teenager brought this on.

Why does this matter? Because cause-myths carry blame. A condition rooted in genetics and hormone signaling is not a personal failing, and understanding the actual mechanism is the first step toward asking the right questions about management.

How do Japanese treat PCOS? What differs around the world, and what does not

This question surfaces often in searches, usually alongside claims about a national diet or a traditional remedy that supposedly explains lower rates or better outcomes. The evidence does not support any such secret.

What does differ is the diagnostic framework. Japan’s obstetrics and gynecology society uses its own national criteria, which are stricter than Rotterdam in requiring menstrual irregularity together with polycystic ovaries and laboratory evidence of hormonal disturbance, rather than any two of three features. The practical effect is that Japanese criteria identify a narrower group, which can make prevalence figures and treatment statistics look different from those in Europe or North America. It is a difference in who gets counted, not in the biology.

Treatment principles, by contrast, converge across international guidelines. The WHO describes the same broad framework everywhere: lifestyle measures as a foundation, hormonal treatments to regulate cycles and manage androgen-related symptoms when pregnancy is not the goal, ovulation induction when it is, and attention to long-term metabolic health. Japanese clinicians work within this same framework, with variations in which specific medicines are approved and commonly used, as is true in every country.

Traditional herbal medicine is part of mainstream practice in Japan, and some formulations are studied for menstrual disorders. The evidence for these in PCOS specifically is limited and of variable quality, and no international guideline recommends them as a substitute for established treatment. That is not a dismissal; it is what the research currently shows.

The broader lesson is worth stating. When a search result promises that one culture has quietly solved a condition the rest of the world struggles with, the more likely explanation is a difference in definitions, in reporting, or in marketing. Good management looks recognizably similar in Tokyo, Toronto and Cape Town.

Who is usually treated for PCOS, and who is usually asked to wait

Not everyone who meets the criteria needs active treatment, and not everyone with a suggestive picture is diagnosed straight away. Understanding who falls into each group clears up a lot of frustration.

Treatment is usually offered when symptoms interfere with life or when a specific goal is on the table. Someone with very infrequent periods, for instance, may be advised to have a regular withdrawal bleed, because the NHS and Mayo Clinic note that going many months without shedding the uterine lining is associated with thickening of that lining and, over years, a higher risk of endometrial cancer. Someone distressed by hair growth or acne may be offered combined hormonal contraception, which lowers androgen production and increases the protein that binds testosterone, or an anti-androgen medicine that blocks androgen action at the hair follicle. Someone trying to conceive will be steered toward ovulation induction. Someone with raised blood sugar will be counseled on metabolic risk.

Who is asked to wait? Adolescents, most often. Because irregular cycles and follicle-rich ovaries are normal in the years after menarche, clinicians frequently defer a formal diagnosis and instead monitor cycles, treat troubling symptoms individually, and reassess as the reproductive system matures. This is not dismissal. It is an effort to avoid attaching a lifelong label to a developmental phase.

People with the polycystic appearance but no other features are also usually observed rather than treated, since they do not meet the criteria. And people with mild features and no symptoms may reasonably choose surveillance over medication, with periodic checks of blood pressure, blood sugar and cholesterol.

Every one of these paths is a shared decision. The role of this article is to describe the map; the route is chosen with the clinician who knows your history.

What the weeks and months after a PCOS diagnosis usually look like

A PCOS diagnosis rarely comes with a dramatic first week. What follows is closer to a slow recalibration, and knowing the typical rhythm helps people judge whether things are on track.

The first weeks are usually about assessment rather than intervention. Blood tests for glucose or HbA1c (a measure of average blood sugar over roughly three months), cholesterol and blood pressure establish a baseline, because the CDC reports that more than half of people with PCOS develop type 2 diabetes by age 40. If the scan has not already been done and is needed, it happens now. Someone hoping to conceive may be referred to a fertility clinic; someone not planning pregnancy may discuss cycle regulation.

If hormonal treatment for cycles or androgen symptoms begins, expectations should be measured in months. Cycles often become predictable within the first few cycles of combined hormonal contraception, since the bleed is driven by the medicine rather than by ovulation. Skin and hair respond far more slowly. Hair grows in cycles lasting months, so the NHS advises that treatments aimed at excess hair growth generally need to be used for several months before any visible change, and that they slow new growth rather than remove existing hair.

Ovulation induction runs on a different clock, organized around individual cycles. Medicines are taken early in a cycle, ovulation is checked by scan or blood test in the middle, and each cycle is reviewed before the next. The NHS describes this as a course of several monitored cycles under specialist supervision, with a plan for what happens next if ovulation does not occur.

Lifestyle changes, where relevant, tend to show up first in energy and blood sugar readings and only later in cycles. Patience is not a platitude here; it is a description of the biology.

What people often get wrong about PCOS: the long-term health picture

Beyond the two headline myths, a cluster of smaller misunderstandings shapes how people live with this condition. Correcting them matters because several concern health decades away.

Myth: PCOS ends at menopause. The ovarian features do fade as ovulation stops for everyone, but the metabolic pattern does not switch off. The CDC and Mayo Clinic describe raised lifetime risks of type 2 diabetes, high blood pressure, unfavorable cholesterol and cardiovascular disease. The CDC’s figure that more than half of people with PCOS develop type 2 diabetes by age 40 is exactly why guidelines recommend periodic metabolic screening regardless of whether periods are still a concern.

Myth: irregular periods are harmless if you are not trying to conceive. Very infrequent periods allow the uterine lining to build without being shed. Over years this is associated with a higher risk of endometrial cancer, which is why clinicians often recommend ensuring a bleed at least every few months, either naturally or with medication.

Myth: the condition is purely gynecological. It touches sleep, mood, skin, weight regulation and cardiovascular health. The best care is coordinated across those areas rather than confined to one specialty.

Myth: supplements can replace treatment. Inositol, a naturally occurring compound related to B vitamins, is heavily marketed for PCOS. Some small studies suggest it may influence insulin signaling, but the evidence remains limited and inconsistent, and it is not recommended by mainstream guidelines as a substitute for established care. Vitamin D deficiency is common in PCOS and worth checking, but correcting it treats the deficiency, not the syndrome.

Myth: a normal ultrasound later means the PCOS is gone. Ovarian appearance fluctuates with age, weight and medication. The diagnosis reflects an ongoing hormonal pattern, not a snapshot.

None of these is cause for alarm. Each is a reason to stay connected to routine care.

Questions to ask your care team about PCOS

Appointments are short and the condition is wide. A handful of well-aimed questions helps the conversation cover what matters rather than what happens to come up. These are framed for discussion, not as demands, and the answers will differ from person to person.

• Which of the three diagnostic features do I have, and which other conditions were ruled out before you settled on PCOS?
• Do my results suggest insulin resistance, and what baseline metabolic tests should I have now?
• How often should my blood sugar, blood pressure and cholesterol be rechecked over the coming years?
• I am (or am not) planning a pregnancy in the next year or two. How does that change which options make sense for me right now?
• If we start a medicine, what is it doing in the body, how long before I should expect to notice anything, and what would make you change course?
• How infrequent can my periods safely be, and how will we protect the lining of my uterus if cycles remain irregular?
• Are my hair, skin or mood symptoms something you can help with directly, or should I see another specialist alongside you?
• Should I be screened for sleep apnea or for depression and anxiety?
• If I have a daughter or sister, is there anything they should know or watch for?
• What lifestyle changes are actually supported by evidence for someone with my phenotype, rather than generic advice?

Bring a note of your cycle dates for the past several months; it is the single most useful piece of information you can hand a clinician. And if an answer relies on a percentage or a promise, it is fair to ask where the number comes from. Good clinicians welcome that question. Evidence-first care is a two-way habit.

When to call your doctor: red-flag signs with PCOS

Most of PCOS unfolds slowly, and most appointments can be scheduled at a normal pace. A few situations warrant prompt contact, and a smaller number need urgent care. Knowing the difference is part of managing the condition confidently rather than anxiously.

Contact your care team soon if you have gone longer than about three months without a period and are not pregnant or on a medicine that intentionally stops bleeding, since prolonged gaps affect the uterine lining. Also call if you experience unusually heavy or prolonged bleeding, bleeding between periods that is new for you, or any bleeding after menopause. Rapid new hair growth, a deepening voice, or enlargement of the clitoris over weeks rather than years are not typical of PCOS and need evaluation for other androgen-producing causes. New symptoms of high blood sugar, such as excessive thirst, frequent urination or unexplained weight loss, should be checked without delay.

Seek urgent or emergency care for sudden, severe pelvic or lower abdominal pain, particularly with fever, vomiting or fainting, which can signal a twisted or ruptured ovarian structure or an ectopic pregnancy. Chest pain, shortness of breath, or weakness or numbness on one side of the body are emergencies for anyone and should never be attributed to PCOS. If you are pregnant and have severe headache, visual changes or sudden swelling, contact your maternity team immediately.

Mental health is a red flag too. Persistent low mood, loss of interest in things you normally enjoy, or thoughts of harming yourself deserve the same urgency as any physical symptom. Tell someone on your care team, or use a crisis line if you cannot wait for an appointment.

Everything else, from a frustrating cycle to a new acne flare, belongs in a routine visit. The point of this list is not to add worry. It is to make clear which few things should jump the queue, and to leave every decision about what happens next with the clinicians who know you.

Frequently asked questions

Can you have PCOS without cysts on your ovaries?

Yes. PCOS is diagnosed when two of three features are present, and irregular ovulation plus signs of excess androgens meet that threshold without any ultrasound finding. The NHS notes a scan is not needed when the other two features are clear. The so-called cysts are small stalled follicles, and their absence does not exclude the condition.

Is PCOS overdiagnosed?

In some groups, possibly; in others, the reverse. Adolescents can be over-labeled because irregular cycles and follicle-rich ovaries are normal soon after the first period, so clinicians often defer diagnosis. At the same time, the WHO estimates up to 70 percent of affected women worldwide are never diagnosed. The honest answer is that both problems exist side by side.

Why is PCOS controversial among doctors?

Because the definition is broad. Requiring only two of three features means the label covers people with severe insulin resistance and no ovulation as well as people with mild cycle irregularity and acne. Researchers debate whether these belong under one name, whether the name itself misleads, and how much weight ultrasound should carry, especially in younger people.

What are the PCOS and fertility myths that cause the most harm?

The belief that PCOS means you cannot have children, and the belief that it never matters. Neither is accurate. The WHO identifies PCOS as a leading cause of ovulation-related infertility, but many people conceive naturally or with ovulation induction. The effect varies widely, so a diagnosis is a reason to plan with a specialist, not to assume an outcome.

What are uncommon signs of PCOS?

Less familiar features include thinning hair at the crown, velvety darkened skin patches in the neck or armpits (acanthosis nigricans), skin tags, loud snoring or daytime exhaustion linked to sleep apnea, and low mood or anxiety, according to Mayo Clinic and Cleveland Clinic. Some people have no symptoms at all. These are points to raise with a clinician, not a self-diagnosis tool.

How do Japanese treat PCOS differently?

The main difference is diagnostic. Japan uses national criteria that are stricter than the Rotterdam approach, so a narrower group is identified. Treatment principles match international guidelines: lifestyle measures, hormonal cycle regulation, ovulation induction when pregnancy is wanted, and attention to metabolic health. Claims of a distinct national diet or remedy that resolves PCOS are not supported by evidence.

Does PCOS go away after menopause?

The ovarian and menstrual features fade as ovulation stops for everyone, but the metabolic pattern persists. The CDC and Mayo Clinic describe lifelong raised risks of type 2 diabetes, high blood pressure and cardiovascular disease. Periodic screening of blood sugar, blood pressure and cholesterol remains relevant well beyond the reproductive years.

Can thin women have PCOS?

Yes. PCOS occurs across all body sizes, and people at lower weights may show the same irregular cycles and androgen excess. They are often diagnosed later because their appearance does not fit the stereotype. Insulin resistance can still be present, so metabolic screening is still recommended, though weight-focused advice is not relevant for them.

Do I need to treat PCOS if I am not trying to get pregnant?

Often something is still worth addressing, but what depends on your features. Very infrequent periods let the uterine lining build up, which over years raises endometrial cancer risk, so clinicians often recommend ensuring regular bleeds. Metabolic screening matters regardless of symptoms. Whether to treat hair, skin or mood symptoms is a personal choice made with your care team.

Does eating sugar cause PCOS?

No. PCOS arises from a mix of inherited tendency and hormone signaling, particularly involving insulin and androgens, according to the NIH and Mayo Clinic. A diet heavy in refined carbohydrates can worsen insulin resistance in someone who already has the condition, which is why dietary patterns are part of management, but it does not cause the syndrome.
