Understanding PCOS and Its Impact on Health

Polycystic ovarian syndrome (PCOS) has recently been in a lot of talks due to its name change. On May 12, 2026, a global coalition of 56 patient and professional organisations, including the Endocrine Society, officially renamed the condition. It is no longer called polycystic ovary syndrome. The new name is PMOS: polyendocrine metabolic ovarian syndrome. The reason was how the condition is always very confusing for most women and is way less understood. Some women find out they have it in their teens. Others spend years managing symptoms they never connect to a single cause. A few only discover it when they are trying to conceive and cannot. So read on to understand what PCOS actually is, what it does to the body beyond periods, and what managing it looks like in practice.

What Is PCOS?

PCOS (now PMOS) is a hormonal condition in which the ovaries produce too much androgen (a group of hormones that all women have, but in small amounts). That excess disrupts the normal process of egg development. Eggs might start to develop, but they never fully mature or get released. And over time, those undeveloped follicles can accumulate in the ovaries. 

The name polycystic ovarian syndrome is a little misleading for two main reasons: 

• The "cysts" are not actually cysts in the usual sense. They are follicles that did not complete their cycle. Not every woman with PCOS even has them visible on an ultrasound.
• The name kept the focus entirely on the ovaries, when the real drivers of the condition are hormonal and metabolic. 

The new name, PMOS, gives equal weight to the endocrine and metabolic features that are responsible for most of the long-term health consequences. 

What Causes PCOS?

No single cause explains every case. PCOS is better understood as a combination of factors that compound each other. Here is what drives it:

• Insulin Resistance: The body's reduced ability to use insulin effectively. When insulin builds up, it signals the ovaries to produce more androgens. This is the key mechanism in most PCOS cases and why diet plays such a significant role.
• Genetics: PCOS runs in families. If your mother or sister has it, your own risk is higher.
• Chronic Low-Grade Inflammation: Women with PCOS consistently show elevated inflammatory markers, which independently push androgen production up.
• Lifestyle: A diet heavy in refined carbohydrates, physical inactivity, and excess weight around the abdomen all worsen insulin resistance and amplify symptoms over time.

What Are the Common Symptoms of PCOS?

Symptoms vary enough between women that PCOS is frequently missed at a first consultation. Some women have most of these. Others have only one or two:

• Irregular or absent periods. Without regular ovulation, cycles become unpredictable or stop entirely.
• Excess facial or body hair on the chin, upper lip, or abdomen, driven by elevated androgens.
• Persistent acne, particularly on the jaw and lower face, is often more resistant than typical acne to standard treatments.
• Scalp hair thinning at the crown or temples.
• Weight gain mainly around the abdomen and does not change despite effort.
• Difficulty conceiving, as PCOS is one of the most common causes of ovulatory infertility.
• Low mood, anxiety, and difficulty with emotional regulation, which are more common in women with PCOS than in the general population.

What Does PCOS Impact Your Health Beyond Periods?

This is the part most women never hear at diagnosis. PCOS is not just a reproductive condition. It is a metabolic one, and it carries risks that extend well beyond the years when fertility is a concern.

Women with PCOS have a type 2 diabetes prevalence of 35%, compared to 10% in women without it, according to the World Journal of Diabetes. That is more than three times the rate, driven almost entirely by chronic insulin resistance.

Beyond diabetes, PCOS is associated with:

• High blood pressure, which appears earlier in women with PCOS than in the general female population.
• Fatty liver disease, even in women who do not drink alcohol, is linked to the same insulin resistance that drives the hormonal imbalance.
• Higher risk of endometrial cancer, as infrequent periods mean the uterine lining is not shed regularly. Over the years, this can lead to abnormal thickening that raises cancer risk.
• The cardiovascular risk factors associated with PCOS tend to show up earlier than expected, sometimes in a woman's 30s.
• Depression and anxiety rates in PCOS are also very high, but they rarely get addressed alongside the physical symptoms.

Unmanaged PCOS does not just affect your menstrual cycle. It shapes your health in ways that a blood test can already show well before symptoms become obvious.

How Is PCOS Treated?

PCOS treatment is not something that is created for one and applied to all. It varies person to person. And there is no single medication that resolves all of it. Treatment is more focused on management. So here is what actually works:

Lifestyle Changes

For most women with PCOS, lifestyle changes are the most consistently effective starting point, and that is not a polite way of saying "just lose weight." 

• A weight reduction of 5 to 10% of body weight improves hormonal balance, period regularity, and insulin sensitivity. So does reducing refined carbohydrates specifically, because it directly lowers the insulin spike that drives androgen production.
• Regular exercise, even 30 minutes of walking most days, improves insulin sensitivity independently of any weight change.

Medication When Needed

• Metformin improves insulin sensitivity and, in many women, can result in regular ovulation. It also addresses the metabolic risks PCOS carries.
• Combined oral contraceptive pills regulate periods and reduce androgen-driven symptoms like acne and facial hair, though they do not address the underlying insulin resistance.
• Letrozole is the current guideline-preferred option for women with PCOS who are trying to conceive and need ovulation support.

PCOS is a condition most women manage for decades. The earlier it is identified and addressed, the better the long-term outcome, both for reproductive health and for the metabolic risks that accumulate silently over time.

If you have irregular periods, symptoms that have not been explained, or a family history of PCOS, visitApollo Clinic to get a proper assessment as part of your preventive healthcare routine.

FAQs

1. Can PCOS affect the liver even if I do not drink alcohol?

Yes. About one in three Indian women with PCOS develops non-alcoholic fatty liver disease, caused by insulin resistance rather than alcohol. It rarely causes symptoms until liver function is already affected.

2. Does PCOS affect my chances of conceiving?

It can, but most women with PMOS do conceive with the right treatment. PCOS is one of the most common causes of ovulatory infertility, and letrozole restores ovulation in most cases.

3. Can PCOS cause depression or anxiety?

Yes. Depression and anxiety are very common in women with PCOS. They mainly occur due to hormonal imbalance, visible symptoms like acne and hair changes, and the emotional weight of the diagnosis.

4. Can PMOS lead to type 2 diabetes? 

Yes. Women with PMOS develop type 2 diabetes at three times the rate of women without it. The risk builds from chronic insulin resistance and can emerge as early as your 30s.
