PCOS Explained | Causes, Symptoms & Treatment | Dr. Farwa Hameed

PCOS is one of the most common hormonal concerns among women, but it is also one of the most misunderstood. Many patients hear the word “cysts” and immediately think the main problem is inside the ovaries. Others are told they have PCOS after one ultrasound, without anyone explaining what it means, why it happens, or how treatment should be planned.

This page is written alongside Dr. Farwa Hameed’s patient education video on PCOS. The goal is to help you understand the condition in simple terms before or after watching the video, so you know what questions to ask and when to seek proper evaluation from the best gynecologist in Islamabad.

PCOS can affect periods, skin, hair growth, weight, ovulation, fertility, and long-term metabolic health. But it does not look the same in every woman. Some patients have missed periods and facial hair. Others only struggle with acne, weight gain, or difficulty conceiving. This is why diagnosis and treatment should be based on your symptoms, tests, and personal goals.

Quick answer: what is PCOS?

PCOS is a hormonal disorder where the ovaries produce more androgens than normal. Androgens are male-type hormones that women also have in smaller amounts. When androgen levels are higher than they should be, ovulation can become irregular. This may lead to missed periods, acne, excess facial or body hair, scalp hair thinning, weight changes, and fertility problems.

PCOS is usually diagnosed when two out of three Rotterdam criteria are present: irregular ovulation, elevated androgens, or polycystic-appearing ovaries on ultrasound. Treatment depends on the patient’s goal. Some women want to control symptoms and regulate periods, while others are trying to conceive and need ovulation support.

What PCOS actually is and what the name gets wrong

The name “polycystic ovary syndrome” can be confusing. Many women assume PCOS means there are dangerous cysts in the ovaries. That is not accurate. The small fluid-filled follicles seen on ultrasound are not the same as harmful cysts that need surgery. In fact, some women with PCOS do not have polycystic ovaries on ultrasound at all.

PCOS is mainly a hormonal and metabolic condition. The core issue is often irregular ovulation and higher androgen levels. When ovulation does not happen regularly, periods may become delayed, skipped, or unpredictable. Higher androgens can affect the skin and hair, causing acne, oily skin, facial hair, or scalp hair thinning.

This is why PCOS symptoms vary so much between women. One patient may have regular weight but severe acne and facial hair. Another may have no skin symptoms but has not had a period for three months. A third patient may only discover PCOS when she starts trying to conceive.

What causes PCOS?

There is no single cause of PCOS. It is usually linked to a mix of hormonal imbalance, insulin resistance, genetics, and ovarian response. This matters because blaming PCOS on one habit or one lifestyle choice is not helpful and often makes patients feel guilty without reason.

Insulin resistance

Insulin is the hormone that helps move sugar from the blood into the body’s cells. In insulin resistance, the body has to produce more insulin to do the same job. Higher insulin levels can stimulate the ovaries to produce more androgens. This can disturb ovulation and worsen symptoms like irregular periods, acne, facial hair, and weight gain around the abdomen.

This is why weight, blood sugar, and diet are important parts of PCOS management. Not every woman with PCOS is overweight, but insulin resistance can still be present. Lifestyle changes are not about blame. They are used because they can improve insulin sensitivity and help hormones work better.

Genetics

Family history also plays a role. If your mother, sister, or close female relatives have irregular periods, fertility issues, facial hair, diabetes, or PCOS, your risk may be higher. PCOS can also look different across generations. One woman may have mostly fertility issues, while another may have acne, weight gain, or irregular cycles.

What is still not fully known

The exact cause of PCOS is still not fully established. Doctors understand many of the hormonal and metabolic patterns, but there is no single trigger that explains every case. This is important for patients to understand because PCOS is not caused by one food, one mistake, or one lifestyle factor.

A proper plan should focus on what is happening in your body now: your cycle pattern, androgen levels, insulin resistance, fertility goals, and long-term health risks.

Recognising the symptoms of PCOS

PCOS symptoms can be mild, severe, or confusing. Some women only notice period changes. Others have skin, hair, weight, and fertility concerns together. The table below explains common symptoms and what they may mean.

A woman does not need every symptom to have PCOS. Two or three symptoms together are enough to warrant a proper evaluation, especially if periods are irregular or fertility is becoming a concern.

If irregular cycles are your main concern, this guide on irregular periods and when to seek help may help you understand when cycle changes should be checked.

How PCOS is diagnosed

PCOS should not be diagnosed from one symptom or one ultrasound alone. A proper diagnosis uses history, symptoms, blood tests, and ultrasound when needed. The widely used Rotterdam criteria require two out of three findings: irregular ovulation, elevated androgens, or polycystic-appearing ovaries on ultrasound.

Irregular ovulation usually shows up as delayed periods, missed periods, or very unpredictable cycles. Elevated androgens may be seen through symptoms like facial hair, acne, oily skin, or scalp hair thinning. They may also be confirmed through blood tests such as total or free testosterone.

Blood tests may include testosterone, LH, FSH, prolactin, thyroid function, fasting glucose, and insulin-related markers depending on the patient. These tests help understand the hormonal pattern and also rule out other conditions that can look like PCOS.

A pelvic ultrasound can show ovarian appearance and follicle pattern, but it cannot confirm PCOS on its own. Some women have polycystic-appearing ovaries without PCOS. Others have PCOS even when the ultrasound does not look typical. This is why symptoms and blood tests matter.

Before confirming PCOS, doctors may need to rule out thyroid disorders and hyperprolactinemia because both can cause irregular periods and hormonal symptoms. Treating the wrong condition as PCOS can delay proper care.

Treatment matched to your goal

PCOS treatment is not the same for every patient. The right plan depends on whether you want to manage symptoms, regulate periods, improve skin and hair concerns, reduce insulin resistance, or conceive. This is why treatment should always start with a clear goal.

If you are managing symptoms and not planning pregnancy

When pregnancy is not planned, treatment often focuses on cycle regulation, androgen control, insulin resistance, and long-term health protection. Lifestyle changes are usually the starting point, especially when weight gain, abdominal fat, sugar cravings, or insulin resistance are present.

A lower glycemic diet, regular walking or exercise, better sleep, and weight management can improve insulin sensitivity. Even small improvements can help periods become more regular in some women.

Hormonal contraceptives may be used to regulate bleeding and reduce androgen-related symptoms such as acne or excess hair growth. They do not cure PCOS, but they can help control symptoms while the patient is using them.

Metformin may be considered when insulin resistance is a major part of the picture. Anti-androgen medicines may be used for persistent hair or skin symptoms when other treatments are not enough. These medicines should only be taken after medical advice, especially because some are not safe during pregnancy.

If you are trying to conceive

If pregnancy is the goal, the treatment approach changes. Hormonal contraceptives are usually stopped because the focus becomes ovulation. Many women with PCOS do not ovulate regularly, so pregnancy may not happen even if everything else is normal.

Ovulation induction medicines may be used to help the ovary release an egg. Letrozole is commonly used as a first-choice medication for ovulation induction in women with PCOS-related anovulatory infertility, when there are no other major infertility factors. The dose and monitoring plan should be decided by a doctor.

If medication alone does not work, the doctor may review ovulation tracking, partner semen analysis, fallopian tube testing, and other factors. The next steps may include different medication plans, further fertility evaluation, IUI, or IVF depending on the couple’s situation.

Not every PCOS patient needs IVF. Many women conceive after ovulation is restored and timing is guided properly. If you have been trying for several months, this page on when couples should get checked for fertility can help you understand when to seek evaluation.

Long-term health considerations

PCOS management should not stop as soon as acne improves or periods become temporarily regular. PCOS can be linked with insulin resistance, type 2 diabetes risk, abnormal cholesterol, high blood pressure, and cardiovascular risk over time.

Irregular periods also need monitoring because long gaps without bleeding can affect the uterine lining. This is why missed periods should not be ignored for months. Your doctor may suggest cycle regulation or periodic bleeding depending on your case.

Long-term care may include blood sugar monitoring, weight and waist tracking, blood pressure checks, lipid profile, and review of menstrual pattern. The aim is not only to treat today’s symptoms but also to protect future health.

Dr. Farwa’s clinical perspective

In my practice, I often meet patients who are confused about what PCOS actually is. Some are frightened because they think “cysts” mean surgery. Others have been given medicines without understanding whether the goal is period control, skin improvement, weight management, or pregnancy.

That is one reason I made this video. When patients understand the basics before consultation, the appointment becomes more useful. They can explain their symptoms clearly, ask better questions, and understand why certain tests or medicines are recommended.

My approach to PCOS is goal-based and stepwise. I do not treat every patient the same way. A 19-year-old with acne and missed periods needs a different plan from a 32-year-old trying to conceive. A patient with insulin resistance needs attention to metabolic health, not only a period-regulating tablet.

With FCPS training, MRCOG (UK), over 14 years of experience, and clinic access in G-11 and G-13 Islamabad, my goal is to help women understand their diagnosis clearly and choose treatment that matches their stage of life and health goals.

When should you book a PCOS evaluation?

You should consider a PCOS evaluation if your periods are often delayed, you miss periods for months, acne is not improving, facial hair is increasing, weight is difficult to manage, or pregnancy is not happening after trying. You should also get checked if another doctor has mentioned PCOS but did not explain the diagnosis properly.

A good evaluation can help confirm whether you truly have PCOS, whether another hormonal issue is involved, and what treatment is suitable for your goal.
