PCOS symptoms complications awareness

Overview

Polycystic ovary syndrome (PCOS) is a hormonal condition that affects people with ovaries. In PCOS, the ovaries often produce higher levels of androgens (male-type hormones), which can interfere with the regular release of eggs. This often causes irregular periods, small fluid-filled sacs (follicles) in the ovaries, and symptoms like acne and excess hair growth.

Yes. PCOS is one of the most common endocrine (hormone) disorders. The World Health Organization estimates that about 8–13% of people of reproductive age with ovaries have PCOS. Many people are unaware they have it until they seek help for irregular periods or difficulty conceiving.

PCOS can affect anyone with ovaries, regardless of background. It often first shows up in the teenage years after the first period, but may be diagnosed later in life. It is most often recognised during the reproductive years, especially when a person tries to get pregnant or sees a doctor for missed periods, acne, or excess hair growth.

Symptoms

Common symptoms

• Irregular, missed, or very heavy periods
• Excess facial or body hair (hirsutism) or thinning hair on the scalp
• Acne on the face, chest, or upper back
• Weight gain, especially around the abdomen
• Darkened, velvety patches of skin on the neck, armpits, or groin (a sign of insulin resistance)
• Difficulty getting pregnant because ovulation is irregular
• Mood changes, anxiety, or low mood

Causes

Main causes

• The exact cause of PCOS is not fully known, but it tends to run in families, so genetics plays a strong role.
• Insulin resistance is very common in PCOS. When the body does not use insulin well, the pancreas makes extra insulin. High insulin can cause the ovaries to produce more androgens, which prevents ovulation.
• There is also an imbalance in reproductive hormones — higher levels of luteinising hormone and lower levels of follicle-stimulating hormone — which disrupts normal egg development.

Risk factors

• A family history of PCOS in your mother or sister
• A personal or family history of type 2 diabetes
• Being overweight or having obesity
• High blood pressure or abnormal cholesterol (metabolic syndrome)
• Having another hormonal condition, such as an overactive adrenal gland (rare)

When to see a doctor

See a doctor urgently if:

• Sudden, severe pain in your belly or pelvis that does not ease
• Very heavy bleeding that soaks through a pad or tampon every hour for more than 2 hours
• Fever with pelvic pain
• Signs of a stroke — face drooping, arm weakness, or difficulty speaking (call emergency immediately)
• Pain, swelling, or redness in one leg that is new (possible blood clot)

Book a routine appointment if:

• Your periods are irregular, missing, or extremely painful
• You have acne, excess hair growth, or hair loss that is bothering you
• You have been trying to conceive for over a year (or 6 months if you are over 35) without success
• You have a family history of PCOS or type 2 diabetes and want a check-up

Diagnosis

There is no single test for PCOS. Doctors use the Rotterdam criteria, which require at least two of the following: (1) irregular or absent periods, (2) signs of excess androgens (symptoms like acne or hair growth, or a blood test showing high androgen levels), and (3) an ultrasound showing many small follicles in the ovaries. Before diagnosing PCOS, doctors will rule out other conditions such as thyroid disease or high prolactin.

Tests that may be done

• A detailed conversation about your cycle, symptoms, and family history
• Blood tests for hormone levels (androgens, FSH, LH, prolactin, thyroid function)
• Blood tests for blood sugar (fasting glucose or HbA1c) to screen for insulin resistance or diabetes
• A fasting lipid panel to check cholesterol and triglycerides
• A pelvic ultrasound to look at the ovaries and the thickness of the uterine lining
• A pregnancy test if periods are missed

What to expect at your appointment

Your first appointment may feel a little intense — the doctor will ask about your periods, weight changes, skin, hair, and any plans around pregnancy. They may also perform a physical and possibly a pelvic exam if you are comfortable. The tests are simple: mostly blood draws and an ultrasound. You may be referred to a gynaecologist or an endocrinologist (a hormone specialist) for further management.

Treatment

Treatment for PCOS is highly personalised. It focuses on managing symptoms, supporting fertility if desired, and lowering long-term health risks. There is no cure, but a combination of lifestyle changes and medical treatments can help regulate periods, improve skin and hair, support ovulation, and protect against diabetes and heart disease. Even a modest weight loss of 5–10% can make a meaningful difference for many people.

Self-care at home

• Eat regular meals with plenty of vegetables, whole grains, lean protein, and healthy fats
• Move your body most days — aim for at least 150 minutes of brisk activity each week
• Include strength training (like lifting weights or bodyweight exercises) twice a week
• Prioritise sleep and aim for 7–9 hours each night
• Manage stress with breathing exercises, journaling, or gentle yoga
• Track your periods in a calendar or app to notice any changes

Medical treatments

Your healthcare provider may discuss hormonal birth control (the pill, patch, or vaginal ring) to regulate periods and reduce acne and hair growth. Other medicines that block androgens or help the body respond better to insulin can also be considered. If you are trying to conceive, a doctor may offer a tablet or injection that helps stimulate ovulation. These are general approaches — your doctor will choose a plan tailored to your needs and preferences. Always ask your pharmacist or doctor about how a medicine works, its benefits, and possible side effects.

When is surgery considered?

Surgery is not a routine treatment for PCOS. A procedure called laparoscopic ovarian drilling — making tiny punctures in the ovary — is sometimes tried when ovulation medicines do not work and fertility is a goal. It is not a first-line treatment and is only offered after careful discussion with a specialist about risks and benefits.

Living with this condition

Living with PCOS can feel like a juggling act, but it is manageable. Focus on building small, sustainable routines around meals, movement, sleep, and stress. Some days will be harder than others, and that is completely normal. Be kind to yourself and lean on the people you trust.

Lifestyle tips

• Find activities you enjoy — whether that is walking, swimming, dancing, or team sports
• Cook more meals at home using simple, whole ingredients
• Eat slowly and mindfully — notice your hunger and fullness cues
• Set a regular bedtime and put screens away 30 minutes before sleep
• Drink plenty of water throughout the day
• Schedule time to unwind each day, even if it is only 10 minutes

Diet and exercise

You do not need a special or highly restrictive 'PCOS diet'. A balanced Mediterranean-style pattern — rich in vegetables, fruit, whole grains, beans, nuts, fish, and olive oil, with limited ultra-processed foods and sugary drinks — works well for most people. For exercise, combine aerobic activity like brisk walking or cycling with two days of strength training. Start slowly and be consistent; progress matters more than perfection.

Mental health and emotional wellbeing

PCOS can affect how you feel about yourself and your body. Acne, hair growth, weight changes, and worries about fertility can be distressing. Research shows that people with PCOS are more likely to experience anxiety and depression. These feelings are completely valid. Please talk to your healthcare provider about them. If you have thoughts of harming yourself, call a crisis line or go to your local emergency department right away — reaching out is a sign of strength.

Prevention

PCOS cannot be fully prevented because it is strongly linked to genes. However, you can prevent or delay many of its complications. Maintaining a healthy weight, staying physically active, and eating a balanced diet from an early age can reduce insulin resistance and may lower the chance of diabetes and heart disease linked to PCOS.

Screening programmes

Because PCOS raises your risk of insulin resistance, diabetes, and cardiovascular disease, regular monitoring is important. Your doctor may recommend checking blood pressure yearly, and measuring fasting blood sugar (or HbA1c) and cholesterol every one to two years. Like everyone, you should also follow national guidelines for cervical screening and other routine health checks.

Complications

If left untreated

• Type 2 diabetes — from long-standing insulin resistance
• High blood pressure and abnormal blood lipids
• Cardiovascular disease, including heart attack and stroke
• Endometrial hyperplasia (thickening of the womb lining) and, in rare cases, endometrial cancer, because the uterine lining is not shed regularly
• Sleep apnoea, where breathing repeatedly stops during sleep
• Infertility or subfertility due to irregular ovulation
• Pregnancy complications such as gestational diabetes, pre-eclampsia, and premature birth
• Non-alcoholic fatty liver disease

Long-term outlook

The outlook for PCOS is very positive, especially when it is identified early. With a combination of lifestyle changes, medical support, and regular monitoring, most people with PCOS lead healthy, full lives — and many go on to have children if that is what they want. PCOS is a lifelong condition, but it is very treatable. Small, consistent steps can dramatically reduce long-term risks and improve how you feel day to day.
