PCOS: Symptoms, Causes & When to See a Doctor
Learn about PCOS symptoms, possible causes, diagnosis and treatment options, and when to consult a healthcare professional for irregular periods or other concerns.
What Is PCOS?
Polycystic ovary syndrome (PCOS) is a common hormonal condition that can affect the menstrual cycle, skin, hair growth and the way the ovaries function. It may also be associated with insulin resistance and an increased risk of certain long-term health problems.
PCOS affects different people in different ways. Some experience irregular periods or acne, while others notice unwanted hair growth, hair thinning or difficulty becoming pregnant.
Having one of these symptoms does not automatically mean you have PCOS. A qualified healthcare professional can assess your symptoms, medical history and test results to determine the possible cause.
What Are the Common Symptoms of PCOS?
PCOS symptoms can vary from person to person. They may begin during adolescence or become noticeable later.
1. Irregular Periods
Irregular menstrual cycles are one of the common features of PCOS. Periods may occur less frequently than expected, become unpredictable or stop for several months.
These changes can happen when ovulation does not occur regularly.
If your periods are persistently irregular or you miss periods repeatedly, consult a healthcare professional rather than assuming PCOS is the cause.
2. Acne and Oily Skin
Some people with PCOS experience persistent acne or oily skin. These symptoms may be associated with higher levels of androgens, which are hormones present in people of all sexes.
Acne can have many other causes, so a skin problem alone cannot confirm PCOS.
3. Excess Facial or Body Hair
Increased hair growth on areas such as the face, chin, chest or abdomen may occur in people with PCOS.
This can be associated with higher androgen levels. If excess hair growth develops suddenly or progresses rapidly, seek medical assessment because other conditions may need to be considered.
4. Hair Thinning
Some people experience thinning hair on the scalp, particularly around the crown or parting.
Hair thinning can also result from thyroid problems, nutritional deficiencies, genetics and other conditions. A doctor can help assess the likely cause before recommending treatment.
5. Weight Changes
Some people with PCOS experience weight gain or find weight management difficult. Others do not have excess weight.
PCOS can occur across a range of body sizes. Weight alone cannot diagnose or rule out the condition, and treatment should be tailored to individual needs without stigma.
6. Difficulty Becoming Pregnant
PCOS can affect ovulation, which may make it more difficult for some people to become pregnant.
However, PCOS does not automatically mean infertility. Many people with PCOS can conceive, sometimes with medical support.
If you are trying to become pregnant and have irregular periods, speak with a qualified healthcare professional about your options.
What Causes PCOS?
The exact cause of PCOS is not fully understood. It is thought to involve a combination of hormonal, genetic and metabolic factors.
Hormonal Imbalances
Some people with PCOS have higher levels of androgens. These hormones can contribute to symptoms such as acne, increased facial hair and scalp hair thinning.
Hormonal changes can also affect regular ovulation and menstrual cycles.
Insulin Resistance
Insulin helps the body use glucose for energy. In some people with PCOS, the body does not respond to insulin as effectively as it should.
This is known as insulin resistance. The body may produce more insulin to compensate, and higher insulin levels can contribute to hormonal changes.
Insulin resistance is not present in every person with PCOS, but it is an important factor for doctors to consider.
Family History
PCOS can run in families. Having a close relative with PCOS may increase your likelihood of developing the condition, although family history alone does not determine whether you will have it.
Can Lifestyle Cause PCOS?
PCOS is not simply caused by lifestyle choices. Its development involves several factors, including genetics and hormonal processes.
Healthy eating, regular physical activity, adequate sleep and appropriate medical care can help support overall health and manage some associated risks. They should not be presented as a guaranteed cure.
How Is PCOS Diagnosed?
There is no single test that confirms every case of PCOS. A healthcare professional usually considers your symptoms, medical history, examination findings and relevant investigations.
Depending on your age and circumstances, assessment may include:
- Reviewing menstrual cycle patterns.
- Asking about acne, hair growth and scalp hair thinning.
- Assessing relevant medical and family history.
- Blood tests to evaluate hormone levels.
- Tests for blood sugar or other metabolic risk factors.
- Additional tests to rule out other conditions.
- An ultrasound when clinically appropriate.
In adults, PCOS is generally diagnosed using established clinical criteria after other possible causes have been considered. An ultrasound is not always necessary.
Adolescents require particular care during assessment because irregular periods and acne can be common during puberty. Diagnostic criteria differ from those used for adults.
Do not try to diagnose PCOS using symptoms or an ultrasound report alone. Discuss your results with a qualified healthcare professional.
When Should You See a Doctor for PCOS?
Consider booking an appointment if:
- Your periods are persistently irregular or repeatedly absent.
- You experience unwanted facial or body hair growth.
- You have persistent acne along with menstrual changes.
- You notice unexplained scalp hair thinning.
- You have concerns about fertility or ovulation.
- You have been diagnosed with PCOS and need ongoing care.
- You want advice about blood sugar or other metabolic risks.
A Gynaecologist is a suitable specialist for many menstrual and reproductive health concerns. A General Physician can also be a useful starting point and may coordinate further assessment.
If you have missed a period and pregnancy is possible, consider taking an appropriate pregnancy test and seek medical advice as needed.
Seek prompt medical attention for severe pelvic pain, particularly if it occurs with fainting, heavy bleeding, fever or possible pregnancy. Do not assume sudden severe pain is caused by PCOS.
What Treatment Options Are Available for PCOS?
There is no single treatment that suits everyone with PCOS. Management depends on your symptoms, health risks and whether you are planning a pregnancy.
1. Lifestyle and General Health Support
A balanced approach to health may help support metabolic well-being and symptom management.
Depending on your needs, this may include:
- Eating a varied, balanced diet.
- Being physically active regularly.
- Maintaining a consistent sleep routine.
- Seeking support for stress and emotional well-being.
- Discussing weight-related concerns without stigma.
- Attending recommended follow-up appointments.
These measures can be useful even when weight loss is not needed. They do not replace medical treatment when it is appropriate.
2. Treatment for Irregular Periods
A doctor may recommend hormonal medication to help regulate bleeding or protect the lining of the uterus when periods are very infrequent.
The appropriate option depends on your medical history, risk factors and pregnancy plans. Do not start hormonal medication without professional advice.
3. Treatment for Acne and Excess Hair Growth
Depending on the symptoms, a healthcare professional may recommend skin treatments, hormonal medication or other options.
Some medicines are unsuitable during pregnancy or when trying to conceive. Discuss potential benefits, side effects and pregnancy considerations before starting treatment.
4. Support for Fertility
If PCOS is affecting ovulation and you want to become pregnant, a healthcare professional can discuss appropriate fertility assessment and treatment options.
Treatment depends on your individual circumstances and whether other fertility factors are present. A specialist can help you understand the available options.
5. Monitoring Long-Term Health
Depending on your medical history and risk factors, your doctor may recommend monitoring blood pressure, blood sugar, cholesterol or other aspects of your health.
The appropriate tests and frequency vary from person to person.
Avoid unverified supplements or products that promise to cure PCOS. Discuss any supplement you are considering with your healthcare professional.
Can PCOS Be Managed Long Term?
Yes. Many people manage PCOS with an individualised combination of medical care, lifestyle support and follow-up.
Symptoms may change over time, so your treatment plan may also need adjustment. Regular consultations can help review menstrual health, skin or hair symptoms, fertility goals and metabolic risk factors.
PCOS can affect emotional well-being and body image as well. If symptoms are causing distress, discuss this with a healthcare professional and seek appropriate support.
Which Doctor Should You See for PCOS?
A Gynaecologist can assess irregular periods, hormonal concerns and reproductive health. Depending on your symptoms, you may also benefit from a General Physician, Dermatologist, Endocrinologist or fertility specialist.
You do not need to choose every specialist yourself. Your first doctor can help determine which assessments or referrals are appropriate.
