Clinical Editorial
If you've just been told you have PCOS, or PCOD, or both, depending on which doctor you saw. You probably left the appointment with more questions than answers. What does this actually mean for my body? Is it forever? Can I still have children? Why does every online source describe it differently? This article answers the questions patients actually ask, in one place.
What exactly is PCOS?
PCOS, Polycystic Ovary Syndrome, is a hormonal and metabolic condition, not just an ovarian one. At its core, three things tend to go off balance together: ovulation becomes irregular or stops happening reliably, the ovaries produce higher levels of androgens (male hormones like testosterone) than typical, and, in the majority of cases, the body's cells become less responsive to insulin, a state called insulin resistance.
These three pieces feed each other. Higher insulin pushes the ovaries to make more androgens; higher androgens disrupt the signalling that triggers ovulation; irregular ovulation changes the hormonal environment further. That's why PCOS shows up as a cluster, irregular periods, acne, hair thinning or excess facial/body hair, weight that's hard to shift, and fatigue, rather than a single symptom.
Why is it also called PCOD?
In India, you'll hear both PCOS and PCOD used, often interchangeably, and that's part of the confusion. Strictly speaking, they aren't identical terms.
| PCOS (Polycystic Ovary Syndrome) | PCOD (Polycystic Ovarian Disease) | |
|---|---|---|
| What it describes | A broader endocrine and metabolic syndrome affecting ovulation, hormones, and often insulin sensitivity | A more localized description of ovaries releasing multiple immature or partially mature eggs, some of which develop into small cysts |
| Clinical standing | A formally defined diagnosis with internationally used criteria (see below) | Not a distinct internationally recognised diagnosis, used more colloquially, especially in India |
| Severity | Can involve significant metabolic and fertility implications | Often used to describe milder presentations, though usage varies widely by clinic |
How is PCOS diagnosed?
There's no single test that confirms PCOS. Doctors internationally use the Rotterdam criteria, which requires at least two of the following three findings, after other conditions with similar symptoms have been ruled out:
- Irregular or absent ovulation, reflected in irregular, infrequent, or missed periods
- Clinical or biochemical signs of excess androgens, acne, hirsutism (excess facial/body hair), hair thinning, or elevated testosterone/DHEAS on a blood test
- Polycystic-appearing ovaries on ultrasound, a higher number of small follicles or increased ovarian volume
A common misunderstanding
You do not need visible cysts on your ovaries to have PCOS, and having follicles that look 'cystic' on a scan doesn't automatically mean you have PCOS. The ultrasound is only one of three criteria, and it's assessed alongside your symptoms and blood work, not in isolation.
A typical diagnostic work-up includes a menstrual history, a physical exam, a pelvic/transvaginal ultrasound, and blood tests, commonly LH and FSH, testosterone and DHEAS, fasting insulin and glucose (or HbA1c), a lipid profile, and thyroid and prolactin levels to rule out other causes of irregular cycles.
Is PCOS curable?
Not in the sense of a one-time treatment that permanently removes the underlying tendency. PCOS is generally understood as a chronic hormonal and metabolic condition, similar in that sense to how conditions like hypertension or type 2 diabetes are managed rather than 'cured'.
That said, 'not curable' doesn't mean 'nothing changes.' With sustained management of weight, insulin resistance, and hormone levels, many women reach a state where cycles are regular, skin clears up, and labs normalise for years at a time. Symptoms can go into what's effectively long-term remission. It's the underlying predisposition that tends to remain, ready to resurface if the drivers (weight gain, poor sleep, high insulin) come back.
Is PCOS lifelong?
The underlying hormonal and metabolic tendency usually is, yes, but how it shows up changes across life stages. In the reproductive years, irregular cycles and fertility concerns tend to dominate. Around perimenopause, cycle patterns naturally shift again, which can make PCOS harder to distinguish from normal perimenopausal change. After menopause, the ovulation-related symptoms fade, but the insulin resistance and cardiometabolic risk that came with PCOS often persist and matter more for long-term heart and metabolic health.
This is worth internalising early: PCOS isn't just a fertility-years condition. Managing the insulin resistance piece well in your 20s and 30s has payoffs that extend well past your reproductive years.
What about having kids with PCOS?
PCOS is one of the most common causes of anovulatory infertility, but the large majority of women with PCOS who want to conceive are able to, often without needing advanced fertility treatment.
- Weight and insulin management first, for many women with PCOS, even a modest weight loss (around 5–10% of body weight) is enough to restore regular ovulation
- Ovulation induction medication, letrozole is generally used as first-line, with clomiphene as an alternative, to directly trigger ovulation for planned conception cycles
- Metformin, sometimes used alongside ovulation induction, particularly where insulin resistance is prominent
- IVF or other assisted reproduction, considered when the above hasn't worked, or alongside other fertility factors
GLP-1 medication and pregnancy
Semaglutide and tirzepatide are not used during pregnancy or while actively trying to conceive, and are not fertility treatments. If having children is a near-term goal, this needs to be planned with your doctor, including how far in advance to stop GLP-1 therapy before you start trying.
How does GLP-1 medication help with PCOS?
GLP-1 medications like semaglutide and tirzepatide don't treat PCOS directly, they're used off-label because of what they do physiologically: they improve insulin sensitivity and reduce appetite. Since insulin resistance sits upstream of much of PCOS, addressing it can have knock-on effects on weight, and for some women, cycle regularity and androgen-driven symptoms like acne or hair changes.
It's worth being precise about what this does and doesn't mean: results vary significantly between individuals, symptom improvement beyond weight is a possible downstream effect rather than a guaranteed outcome, and GLP-1 therapy is not a substitute for fertility-specific treatment if conceiving is the goal. For the full mechanism and what to expect, see our companion articles on why PCOS makes weight loss harder and what improving insulin resistance can mean for symptoms beyond weight.
What are the other treatment options for PCOS?
There's no single 'PCOS treatment', the right combination depends on what you're solving for: cycle regularity, skin and hair, weight, fertility, or long-term metabolic risk.
| Option | What it does | Typically used for |
|---|---|---|
| Lifestyle (diet, movement, sleep) | Foundational for insulin sensitivity and weight regardless of what else is used | Every PCOS patient, alongside any other treatment |
| Combined oral contraceptives | Regulate cycles and reduce androgen-driven symptoms | Cycle control and acne/hirsutism, when pregnancy isn't the near-term goal |
| Metformin | Improves insulin sensitivity; long-established in PCOS care | Insulin resistance, sometimes alongside fertility treatment |
| Anti-androgens (e.g. spironolactone) | Blocks androgen effects on skin and hair follicles | Hirsutism and acne, usually alongside contraceptives |
| Myo-inositol / D-chiro-inositol | Supplement shown in some studies to support insulin signalling and ovulation | Often used as an adjunct alongside other treatment |
| Letrozole / clomiphene | Ovulation induction | Fertility, when trying to conceive |
| Semaglutide / tirzepatide (GLP-1) | Improves insulin sensitivity and reduces appetite, off-label | Weight and metabolic management, not fertility or pregnancy |
How ALTRcare can help with expert guidance on PCOS
PCOS care goes wrong most often when it's treated as a single symptom to manage rather than a connected condition. At ALTRcare, every patient starts with a proper clinical review: your cycle history, symptoms, relevant labs (or a plan to get the right ones done), and a direct conversation about what you're actually trying to solve for. A doctor then decides what combination of approaches fits your case, including whether a GLP-1 program is appropriate, and follows up over time so the plan adjusts as your picture changes.
Get a real PCOS assessment
Take the 2-minute assessment. A doctor will review your symptoms and goals, cycles, skin, weight, or fertility, before recommending anything.
Key takeaways
- PCOS is a hormonal and metabolic syndrome, irregular ovulation, excess androgens, and (usually) insulin resistance, not just an ovary problem.
- PCOD is often used interchangeably with PCOS in India, but PCOS is the formally defined diagnosis with internationally used criteria.
- Diagnosis needs at least two of three: irregular ovulation, signs of excess androgens, or polycystic-appearing ovaries on ultrasound, plus ruling out other conditions.
- PCOS isn't 'curable' in a permanent sense, but symptoms can be managed into long stretches of remission, and the underlying tendency is generally lifelong.
- Most women with PCOS can conceive, often with weight/insulin management and ovulation induction medication rather than IVF.
- GLP-1 medication is not a PCOS or fertility treatment. It's used off-label for weight and insulin resistance, with other symptom benefits as a possible side effect.

Frequently asked questions
What is the difference between PCOS and PCOD?
PCOS (Polycystic Ovary Syndrome) is the formally defined diagnosis, based on internationally used criteria involving ovulation, androgen levels, and ovarian appearance on ultrasound. PCOD (Polycystic Ovarian Disease) is a less formal term, used mostly in India, often to describe milder or more localized ovarian findings. In everyday clinical use in India, the two terms are frequently used interchangeably.
How is PCOS diagnosed?
Doctors use the Rotterdam criteria, requiring at least two of three findings, irregular or absent ovulation, clinical or biochemical signs of excess androgens, or polycystic-appearing ovaries on ultrasound, after ruling out other conditions like thyroid disorders. Blood tests typically include LH/FSH, testosterone, DHEAS, fasting insulin/glucose, and thyroid levels.
Is PCOS curable?
There's no permanent cure, but it's very manageable. With sustained management of weight, insulin resistance, and hormones, many women reach long periods of regular cycles and clear skin. The underlying predisposition tends to remain, which is why ongoing management matters more than a one-time fix.
Is PCOS a lifelong condition?
The underlying hormonal and metabolic tendency usually is, though how it shows up changes across life stages, fertility concerns in the reproductive years, shifting patterns around perimenopause, and persistent metabolic risk afterward.
Can I get pregnant if I have PCOS?
Yes, most women with PCOS can conceive, often with weight/insulin management and ovulation induction medication such as letrozole, rather than needing IVF. It's one of the most treatable causes of infertility when addressed with the right plan.
Does GLP-1 medication treat PCOS?
Not directly. GLP-1 medications like semaglutide and tirzepatide are used off-label for weight and insulin resistance, which is a root driver of many PCOS symptoms. Any improvement in cycles, skin, or hair is a possible downstream effect, not a guaranteed or primary outcome, and these medications are not used during pregnancy or active conception attempts.
It was never about willpower.
