PCOS Treatment: Complete Management Guide

Polycystic ovary syndrome (PCOS) is a common hormonal and metabolic condition that can affect menstrual cycles, ovulation, skin, hair growth, fertility and long-term health. Symptoms and their severity vary widely, so treatment is based on your individual concerns, health risks and whether you are planning a pregnancy.

There is no single treatment that works for everyone with PCOS. This guide explains the main treatment options, including medicines, lifestyle measures, fertility treatment and long-term monitoring, as well as when you should seek medical advice.

PCOS is a hormonal condition associated with irregular ovulation, increased androgen activity and metabolic changes such as insulin resistance. The name refers to the appearance of the ovaries in some people with PCOS. Despite the name, not everyone with PCOS has polycystic ovaries on an ultrasound, and ovarian cysts alone do not mean that you have PCOS.

In adults, PCOS is generally diagnosed when at least two of the following are present, after other possible causes have been excluded:

• Irregular or absent menstrual periods due to infrequent ovulation
• Clinical or blood-test evidence of increased androgen activity, which may cause acne, excess facial or body hair, or scalp hair thinning
• Polycystic ovarian morphology on ultrasound or, in some cases, an appropriate blood test assessment of ovarian hormone markers

PCOS can increase the risk of several health problems, including:

• Insulin resistance and type 2 diabetes
• High blood pressure and abnormal cholesterol levels
• Cardiovascular risk factors
• Thickening of the lining of the uterus and, over time, an increased risk of endometrial cancer in women with prolonged untreated irregular periods
• Difficulty conceiving because of irregular ovulation
• Pregnancy complications, including gestational diabetes and high blood pressure disorders
• Anxiety and depression

PCOS is a long-term condition, but its symptoms and associated health risks can often be managed effectively. Treatment aims to regulate menstrual cycles, manage androgen-related symptoms, improve metabolic health and support fertility when pregnancy is desired.

The choice of medicine depends on your symptoms, metabolic health, pregnancy plans and other medical conditions. More than one treatment may be used when different symptoms need to be addressed.

Combined Hormonal Contraceptives

Combined oral contraceptive pills may be recommended for women with PCOS who are not trying to conceive. They can help regulate menstrual bleeding and reduce androgen-related symptoms such as acne and excess facial or body hair.

The choice of formulation depends on your medical history and individual risk factors. Combined hormonal contraception may not be suitable for everyone, particularly those with certain cardiovascular or clotting risks.

Metformin for PCOS

Metformin is primarily used to improve blood glucose control in type 2 diabetes. It may also be used in PCOS, particularly when insulin resistance, impaired glucose regulation or other metabolic concerns are present.

Metformin can improve insulin sensitivity and may help some women achieve more regular menstrual cycles and ovulation. It is not suitable for everyone, and the dose may need to be adjusted according to kidney function and other health factors.

Gastrointestinal effects such as nausea, diarrhoea and abdominal discomfort can occur, particularly when treatment is started. These effects often improve over time.

Anti-Androgen Medicines

Anti-androgen medicines may be considered when excess facial or body hair, acne or scalp hair loss remains troublesome despite other treatment.

Spironolactone is one medicine that may be used for androgen-related symptoms. It requires medical supervision and should not be used during pregnancy because of potential effects on fetal development. Reliable contraception is generally required when it is prescribed to someone who could become pregnant.

Progestogen Treatment for Irregular Periods

A progestogen may be prescribed periodically for women who have infrequent periods and cannot use combined hormonal contraception.

It can trigger a withdrawal bleed and help protect the endometrium when periods are very infrequent. Your doctor will determine how often it should be used based on your menstrual pattern and individual risk factors.

Your doctor can help you choose the most suitable PCOS treatment for your symptoms, health needs and pregnancy plans. Regular follow-up can help keep your treatment on track and address any changes over time.

Lifestyle measures are an important part of PCOS management, whether or not you also need medication. They can support metabolic health, menstrual regularity and overall wellbeing.

Weight Management

If you are overweight, even a modest and sustainable reduction in weight may improve insulin sensitivity, menstrual regularity and ovulation. However, weight loss is not the only measure of successful PCOS management, and people with PCOS can have metabolic problems at any body weight.

The focus should be on sustainable eating habits, regular physical activity and other healthy behaviours rather than rapid weight loss.

What Should You Eat?

There is no single PCOS diet that is suitable for everyone. A balanced eating pattern that supports blood glucose control and overall health is generally recommended.

Useful choices include:

• Whole grains such as oats, millets and brown rice
• Vegetables, particularly fibre-rich and non-starchy vegetables
• Pulses, beans and other sources of plant protein
• Eggs, fish, dairy products or other suitable protein sources
• Nuts and seeds in appropriate portions
• Whole fruits rather than fruit juices
• Limiting sugary drinks, highly refined carbohydrates and highly processed foods

Regular meals and balanced portions can also make it easier to maintain stable energy levels and avoid excessive hunger.

Exercise

Regular physical activity can improve insulin sensitivity, cardiovascular health and overall fitness. A practical target for many adults is at least 150 minutes of moderate-intensity physical activity each week, together with muscle-strengthening activities on two or more days.

Brisk walking, cycling, swimming, dancing and resistance exercises can all contribute to your weekly activity. The type and intensity can be adapted to your fitness level and preferences.

PCOS is a common cause of ovulatory infertility, but many women with PCOS can conceive with appropriate treatment.

When irregular or absent ovulation is the main cause of difficulty conceiving, letrozole is generally recommended as the first-line medicine for ovulation induction in women with PCOS who are trying to become pregnant. Other medicines may be considered when necessary.

If oral ovulation-induction treatment is unsuccessful, injectable gonadotrophins or other fertility treatments may be considered under specialist supervision. In vitro fertilisation (IVF) may be an option when other approaches have not been successful or when additional fertility factors are present.

Women with PCOS who become pregnant may have a higher risk of certain pregnancy complications, so appropriate antenatal care and monitoring are important.

PCOS management also involves monitoring health risks that may not cause noticeable symptoms.

Your doctor may recommend assessment of:

• Blood glucose or an appropriate test for glucose regulation
• Blood pressure
• Cholesterol and other lipid levels
• Weight and other measures of metabolic health
• Menstrual pattern and prolonged gaps between periods
• Symptoms of anxiety, depression or other mental health concerns

The frequency of testing depends on your individual risk factors. Women who have very infrequent periods may also need treatment to protect the lining of the uterus.

Not every PCOS treatment is suitable for every woman. Your doctor will consider your medical history, medicines and pregnancy plans before recommending treatment.

• Combined hormonal contraceptives may not be suitable if you have certain clotting disorders, migraine with aura, uncontrolled high blood pressure or specific liver conditions.
• Metformin may require caution or may not be suitable in significant kidney impairment and certain other medical conditions.
• Spironolactone and other anti-androgen medicines should not be used during pregnancy.
• Fertility medicines require appropriate supervision because some treatments can increase the risk of ovarian hyperstimulation and multiple pregnancy.
• Tell your doctor about all medicines, supplements and herbal products you take before starting treatment.
• Do not start, stop or change a PCOS medicine without medical advice.

Speak with a gynaecologist or endocrinologist if you have persistently irregular or absent periods, increased facial or body hair, significant acne, scalp hair thinning, difficulty conceiving or concerns about blood glucose.

You should also seek medical assessment if your menstrual pattern changes significantly, symptoms become difficult to manage or treatment is not providing adequate relief. PCOS treatment needs to be reviewed periodically because your symptoms, health risks and pregnancy plans may change over time.

PCOS is a long-term condition, but appropriate treatment can help manage menstrual irregularities, androgen-related symptoms, metabolic health and fertility. A combination of lifestyle measures, medicines and regular health monitoring may be needed depending on your individual needs.

If you have symptoms of PCOS or have already been diagnosed, work with your doctor to develop a treatment plan based on your symptoms, health risks and reproductive goals. With appropriate management and follow-up, many women with PCOS can maintain good long-term health.
