PCOS in Singapore: Prevalence, Diagnosis Gaps, and Why It's Often Missed

PCOS being common does not make it simple. Its variability is exactly why so many cases slip through the cracks.

A Common but Underrecognised Condition

PCOS is widely recognised as one of the more common endocrine conditions affecting women of reproductive age globally, and Singapore is no exception. Despite this, a meaningful proportion of women remain undiagnosed. The reason is not that PCOS is rare — it is that it can be easy to miss.

This matters because awareness is the first step toward assessment. Many women simply do not realise that symptoms they have lived with for years could be connected.

Why PCOS Is Often Missed

Several factors contribute to the diagnosis gap:

• Varied presentation. PCOS looks different from one woman to the next. Some have prominent skin or hair symptoms; others mainly have irregular cycles; others are slim and don't fit the stereotype.
• The "lean PCOS" blind spot. Women in a normal weight range may be told their symptoms can't be PCOS, when in fact they can.
• Normalised symptoms. Irregular periods or persistent acne are sometimes dismissed as "just how I am," rather than investigated.
• No single test. Because diagnosis relies on combining several features rather than one definitive test, it requires a thorough assessment.

Together, these mean that women can go a long time without a clear explanation for their symptoms.

Why Getting Assessed Matters

PCOS is more than periods or appearance. Because it can be linked to insulin resistance, it may have longer-term metabolic relevance, which is why doctors take it seriously. Studies suggest that earlier awareness and individualised management may help women take a proactive approach to their health.

Getting assessed also means other conditions that mimic PCOS — such as thyroid problems or raised prolactin — can be ruled out. A diagnosis, or its exclusion, brings clarity either way.

What an Assessment Looks Like

A doctor typically reviews your menstrual and symptom history, considers skin and hair changes, arranges relevant blood tests, and sometimes an ultrasound, interpreting these against recognised criteria. The aim is to understand your individual picture, not just apply a label, so that any plan fits you. Telehealth makes starting this process convenient and discreet, from home.

Advocating for Yourself

If your symptoms have been dismissed in the past, it can be discouraging — but it is worth persisting. PCOS is varied, and its less "typical" presentations, including in slim women, are exactly the ones most often overlooked. Knowing this can help you advocate for a thorough assessment rather than accepting a quick brush-off.

Coming to a consultation with a clear account of your symptoms — what you experience, when it started, and how it affects you — helps a doctor build an accurate picture. So does sharing relevant family history and any previous tests. The goal of a good assessment is not just to apply or rule out a label, but to understand your individual situation and what, if anything, may help. Whether the answer is PCOS or something else, getting clarity is worthwhile, and you deserve to have your concerns taken seriously.

When to Speak to a Doctor

Consider speaking to a doctor if you have irregular periods, persistent acne or excess hair growth, unexplained difficulty with weight, trouble conceiving, or simply a long-standing sense that something hormonal is going on. You do not need to have "classic" PCOS to deserve an assessment.

Seek prompt medical attention for very heavy bleeding, severe pelvic pain, or any symptom that worries you.

If your symptoms have been dismissed before, a fresh, thorough assessment can give you the answers you have been missing.
