10 Symptoms of Polycystic Ovary Syndrome (PCOS) You Should Know
Polycystic Ovary Syndrome (PCOS) is a common hormonal and metabolic condition that can affect menstrual cycles, ovulation, skin, hair growth, fertility and metabolic health. However, PCOS does not look the same in every woman. Some women may experience several symptoms, while others may notice only one or two.
Recognising the early symptoms of PCOS can encourage timely medical evaluation and appropriate management.
The most commonly recognised signs include irregular periods, excess facial or body hair, acne, scalp hair thinning, difficulty with ovulation, weight changes and other metabolic or reproductive concerns.
According to the National Institute of Child Health and Human Development (NICHD), PCOS is associated with features such as irregular or absent ovulation, elevated androgen activity and polycystic ovarian morphology. Symptoms can include menstrual irregularities, hirsutism, acne, weight gain, insulin resistance and changes in skin pigmentation.
What Is PCOS?
Polycystic Ovary Syndrome is a hormonal condition involving reproductive and metabolic processes. Despite its name, having "cysts" on the ovaries is not necessary for a diagnosis.
The 2023 International Evidence-based Guideline for PCOS uses three major features when assessing adults:
- Ovulatory dysfunction, often reflected by irregular menstrual cycles
- Clinical or biochemical hyperandrogenism
- Polycystic ovarian morphology or, in appropriate adults, anti-Müllerian hormone (AMH) as an alternative marker
Importantly, other causes of similar symptoms need to be excluded. In adults with both irregular cycles and hyperandrogenism, the 2023 guideline states that an ultrasound or AMH measurement is not necessarily required to establish the diagnosis.
Therefore, experiencing one symptom does not automatically mean you have PCOS. A healthcare professional should evaluate the complete clinical picture.

10 common PCOS symptoms in women
1. Irregular or Missed Periods
One of the most noticeable symptoms of PCOS is an irregular menstrual cycle.
Women with PCOS may experience:
- Periods that occur less frequently
- Missed periods
- Unpredictable menstrual cycles
- Very heavy bleeding in some cases
- Longer gaps between periods
This can happen when ovulation does not occur regularly.
The 2023 international guideline defines irregular menstrual cycles differently depending on age and time since menarche. For adults, cycles shorter than 21 days, longer than 35 days, or fewer than eight cycles per year can indicate irregular cycles.
However, irregular periods can have many causes, including thyroid disorders, significant weight changes, stress, pregnancy and other reproductive conditions.
If your periods have suddenly become irregular or you frequently miss periods, speak with a qualified healthcare professional rather than assuming that PCOS is the cause.

2. Excess Facial or Body Hair
Another common sign associated with PCOS is hirsutism, or excessive coarse hair growth in areas where women typically have less terminal hair.
It may appear on:
- Chin
- Upper lip
- Jawline
- Chest
- Abdomen
- Back
Hirsutism can be associated with increased androgen activity.
The 2023 PCOS guideline considers hirsutism alone to be predictive of biochemical hyperandrogenism and PCOS in adults, although the clinical assessment should consider individual circumstances and ethnicity.
It is important to distinguish unwanted hair growth from normal individual variation. A sudden increase in facial or body hair should be discussed with a healthcare professional.
3. Persistent or Hormonal Acne
Acne is another possible PCOS symptom, particularly when it is persistent, severe or develops later than expected.
Women with PCOS may experience:
- Persistent facial acne
- Jawline acne
- Oily skin
- Breakouts that repeatedly return
- Acne associated with other signs of androgen excess
However, acne by itself does not indicate PCOS.
The 2023 international guideline specifically notes that acne alone, without hirsutism, is a relatively weak predictor of biochemical hyperandrogenism.
Therefore, acne becomes more relevant to PCOS assessment when it occurs alongside irregular periods, hirsutism or other clinical features.
4. Weight Gain or Difficulty Managing Weight
Some women with PCOS experience weight gain or find weight management more difficult.
PCOS is associated with metabolic factors including insulin resistance, and excess weight can also worsen some metabolic and reproductive features.
The NICHD identifies obesity, weight gain and difficulty losing weight particularly around the waist as possible features associated with PCOS.
However, PCOS can occur in women of every body size.
Being overweight is not required to have PCOS, and weight alone cannot diagnose the condition.
A healthy approach focuses on overall metabolic health, balanced nutrition, regular physical activity, adequate sleep and sustainable lifestyle habits rather than rapid weight loss.

5. Thinning Hair or Female-Pattern Hair Loss
PCOS-related androgen activity may also affect scalp hair.
Some women may notice:
- Gradual thinning at the crown
- A widening hair part
- Reduced hair density
- Increased hair shedding
The 2023 guideline recognises female-pattern hair loss as a possible sign of clinical hyperandrogenism, although hair loss alone is not as strongly predictive of biochemical hyperandrogenism as hirsutism.
Hair loss has many possible causes, including nutritional deficiencies, thyroid disorders, stress and other hormonal conditions. A proper evaluation is therefore important.
6. Difficulty With Ovulation or Getting Pregnant
PCOS can affect ovulation, which may make conception more difficult for some women.
When ovulation occurs infrequently, there may be fewer opportunities for conception during a menstrual cycle.
NICHD identifies PCOS as a leading cause of anovulatory infertility. At the same time, having PCOS does not mean that pregnancy is impossible. Many women with PCOS can become pregnant.
If you have been trying to conceive or have concerns about ovulation, consult a qualified healthcare professional for appropriate fertility assessment.

7. Oily Skin
Excess androgen activity can influence the skin's oil production.
Some women with PCOS may notice:
- Increased facial oiliness
- Frequent breakouts
- Enlarged or more visible pores
- Persistent acne
Oily skin by itself is not enough to diagnose PCOS. It becomes more relevant when it appears together with other symptoms such as irregular periods, hirsutism or other signs of androgen excess.
8. Dark, Thickened Patches of Skin
Some women with PCOS may develop acanthosis nigricans, which appears as darker, thicker and sometimes velvety skin.
It may commonly appear around:
- The neck
- Underarms
- Groin
- Other skin folds
Acanthosis nigricans can be associated with insulin resistance.
If you notice new dark or thickened skin, particularly around the neck or underarms, discuss it with a healthcare professional.
9. Fatigue and Reduced Energy
Some women with PCOS report fatigue or low energy.
However, fatigue is not specific to PCOS. It can also occur because of poor sleep, stress, anaemia, thyroid disorders, nutritional deficiencies and many other conditions.
PCOS can coexist with metabolic and psychological health concerns, which is why persistent fatigue should not simply be attributed to hormonal imbalance.
If fatigue is persistent, a healthcare professional can help identify the underlying cause.
Unicare's existing content on PCOS and exercise also discusses lifestyle factors such as physical activity, sleep and stress management.

10. Mood Changes, Anxiety or Emotional Distress
PCOS can affect more than reproductive health. Women living with PCOS may experience emotional and psychological challenges, including anxiety, depression, stress or reduced quality of life.
This does not mean that every mood change is caused by PCOS. Emotional wellbeing can be influenced by many factors, including chronic stress, sleep, relationships, work and other health conditions.
If you are experiencing persistent anxiety, depression or emotional distress, seeking professional support is important.
Can You Have PCOS Without Having All 10 Symptoms?
Yes. PCOS is a highly variable condition. You do not need to experience all of these symptoms. For example, one woman may mainly experience irregular periods and acne, while another may have irregular ovulation, excess facial hair and metabolic concerns.
The diagnosis should be based on appropriate clinical assessment rather than an online symptom checklist.
According to the 2023 international guideline, PCOS assessment considers ovulatory dysfunction, hyperandrogenism and polycystic ovarian morphology/AMH in appropriate adults, while excluding other conditions that can produce similar symptoms.
When Should You See a Doctor for Possible PCOS?
Consider speaking with a healthcare professional if you experience:
- Frequently missed or irregular periods
- New or excessive facial/body hair
- Persistent or severe acne
- Unexplained hair thinning
- Difficulty conceiving
- Significant unexplained weight changes
- Darkened, thickened skin patches
- Persistent fatigue or other concerning symptoms
You should not self-diagnose PCOS based only on symptoms.
A healthcare professional may consider your menstrual history, physical signs, laboratory tests and, when appropriate, ultrasound or other investigations.
