PCOS is one of the most common hormonal conditions in women of reproductive age, and one of the most commonly missed. Many women live with irregular cycles for years before anyone connects the dots. If that sounds familiar, it's worth getting checked — PCOS is very manageable once you know what you're dealing with.
What PCOS actually is
Polycystic ovary syndrome is a hormonal condition, not a disease of the ovaries alone. In PCOS the balance of reproductive hormones is shifted, which can stop ovulation from happening regularly. The name is misleading: the "cysts" seen on an ultrasound are simply small follicles that never matured and released an egg.
It's common — estimates vary between populations, but it affects a meaningful share of women of reproductive age. It's also highly individual: two women with the same diagnosis can have quite different symptoms.
Signs worth checking
PCOS shows up differently in different people. The signs most often worth a consultation are:
- Periods that are irregular, very infrequent, or absent
- Acne that persists past the teenage years, or oily skin
- Coarse hair growth on the face, chest or abdomen
- Thinning hair on the scalp
- Weight that changes easily, or is hard to shift
- Difficulty getting pregnant
You don't need all of these. If irregular cycles are your only symptom, that alone is reason enough to have it looked at.
How it's diagnosed
There's no single test for PCOS. A diagnosis is usually made when at least two of three findings are present, after other causes have been ruled out:
| What's assessed | How |
|---|---|
| Irregular or absent ovulation | your cycle history |
| Raised androgen levels | a blood test, plus signs like acne or hair growth |
| Polycystic ovarian appearance | a pelvic ultrasound |
Because other conditions — thyroid problems among them — can look similar, your doctor will usually check those too. The whole assessment is typically done across one or two visits.
Managing PCOS
There's no cure, but PCOS responds well to treatment — and the right approach depends entirely on what matters to you right now:
- If you want regular cycles — hormonal treatment such as the combined pill is often used to regulate bleeding and protect the uterine lining.
- If acne or hair growth bothers you — treatments that lower androgen effects can help, though they take months to show.
- If insulin resistance is present — medication that improves insulin sensitivity is sometimes prescribed alongside lifestyle changes.
- If you're trying to conceive — treatment shifts toward supporting ovulation, which is a different plan from cycle regulation.
Sustainable lifestyle changes genuinely help, particularly with insulin resistance. A doctor should tailor these to you rather than hand you a generic list.
The long view
PCOS is worth managing beyond the symptoms you can see. Over time it's associated with a higher risk of insulin resistance and type 2 diabetes, and — where periods are very infrequent — with changes to the uterine lining that are worth monitoring.
None of that is a reason to be alarmed. It's a reason to stay in contact with a doctor, have the occasional check, and not disappear for ten years because the symptoms felt manageable. Most women with PCOS who get sensible care do well, including having children.
In Korea this is routine gynecological care — ultrasound and blood work are quick and widely available. What matters most is being able to describe your symptoms accurately, which is far easier in a language you're comfortable in.
Common questions
Can PCOS be cured?
No, but it's very manageable. Treatment targets the symptoms that matter to you and the long-term risks, and many women improve a lot with the right plan.
Does PCOS mean I can't get pregnant?
No. PCOS can make conceiving harder because ovulation is irregular, but many women with PCOS conceive — often with treatment that supports ovulation.
Do I need to stop the pill to be diagnosed?
Sometimes, because hormonal contraception can mask the signs. Your doctor will advise based on your situation — don't stop anything without asking first.
How long does diagnosis take in Korea?
Often one or two visits. An ultrasound can be done at the visit, and blood results usually come back within days.
Can I be seen in English?
Yes. At Ium your symptoms, ultrasound findings, blood results and options are explained in English by a female OB-GYN specialist.
