Polycystic Ovary Syndrome (PCOS): Causes, Symptoms and Treatment

Polycystic Ovary Syndrome (PCOS) is a complex medical condition that affects a significant number of women worldwide. Despite its prevalence, many people still do not fully understand this condition and its health implications. In this article, we will thoroughly explore the causes, symptoms, diagnosis, and treatment options available for PCOS, providing a comprehensive view to help women understand and address this condition effectively.

Causes of Polycystic Ovary Syndrome

Although the precise causes of PCOS are still not completely clear, a combination of genetic, hormonal, and environmental factors are thought to contribute to its development. Here’s a more detailed breakdown of these causes:

Genetic Factors

Genetic predisposition plays a fundamental role in the development of PCOS. If a woman has a family history of PCOS, she is more likely to develop it herself. Studies have identified that certain genes may be involved in hormone regulation and insulin response, key factors in the development of PCOS.

Insulin Resistance

Insulin resistance is a common feature in many women with PCOS. This condition occurs when the body’s cells do not respond properly to insulin, the hormone responsible for regulating blood sugar. In response, the pancreas produces more insulin, which can stimulate the production of androgens (male hormones) in the ovaries. These excess androgens contribute to the characteristic symptoms of PCOS, such as hirsutism and acne.

Hormonal Imbalance

PCOS involves a hormonal imbalance that affects the production and regulation of hormones such as estrogen, progesterone, and androgens. These imbalances can negatively affect regular ovulation and the normal functioning of the ovaries.

Inflammation and Oxidative Stress

Chronic inflammation and oxidative stress may also contribute to the development of PCOS. These factors can increase insulin resistance and affect the overall health of the ovaries and reproductive system.

Symptoms of Polycystic Ovary Syndrome

PCOS presents with a wide range of symptoms, and their severity can vary significantly from woman to woman. Below are some of the most common symptoms associated with PCOS:

Menstrual irregularities

Irregularities in menstrual cycles are a hallmark of PCOS. This can manifest as irregular periods, prolonged menstrual cycles, or no menstruation (amenorrhea). Lack of regular ovulation is responsible for these irregularities.


Hirsutism refers to excessive hair growth in areas where women typically do not have it in large amounts, such as the face, chest, back, and abdomen. High levels of androgens contribute to the development of this symptom.

Acne and Skin Problems:

Hormonal fluctuations in PCOS can cause persistent acne breakouts, especially in the jaw, chin, and back area. Oily skin is also common in women with PCOS.

Changes in Weight and Insulin Resistance

Many women with PCOS experience difficulty controlling their weight. Insulin resistance can increase fat accumulation, especially in the abdominal area. Weight gain can in turn worsen insulin resistance, creating a cycle that can be difficult to break.

Fertility Problems:

PCOS is one of the leading causes of infertility in women. Lack of regular ovulation makes conception difficult, which can be especially distressing for those who want to have children.

Emotional Changes and Mental Health:

Some women with PCOS also experience emotional changes, such as anxiety, depression, and mood swings. The physical and emotional challenges of PCOS can have a negative impact on mental health.

Treatment of Polycystic Ovary Syndrome

PCOS treatment is tailored to each patient’s individual needs and focuses on addressing specific symptoms and improving overall health. Here are several treatment options that may be considered:

Lifestyle Changes

Adopting a healthy lifestyle is essential for PCOS management. This includes a balanced diet and low in refined carbohydrates to control insulin levels. Regular exercise can also help improve insulin sensitivity and reduce symptoms.

Hormonal Medications

Oral contraceptives are commonly prescribed to regulate menstrual cycles and reduce androgen levels. These medications help prevent overgrowth of the uterine lining and decrease symptoms of hirsutism and acne.


Antiandrogen medications block the effects of androgens and can help reduce hirsutism and acne. These medications are often used in combination with oral contraceptives.

Diabetes Medications

In cases of insulin resistance, medications used to treat type 2 diabetes, such as metformin, may be beneficial. These medicines improve insulin sensitivity and help control blood sugar levels.

Fertility Treatments

If conception is an issue, medications to stimulate ovulation, such as clomiphene citrate  or gonadotropin injections, may be prescribed. In more complex cases, assisted reproductive techniques, such as in vitro fertilization (IVF), may be considered.


Ovarian surgery may be an option in rare cases when other treatments have not been successful. This surgery, known as ovarian wedge resection, involves removing a small portion of the ovary to improve ovulation.

Weight Management and Metabolic Health

Since weight gain and insulin resistance are common in PCOS, working with a medical team to manage weight and improve metabolic health is essential. A multidisciplinary approach that includes guidance from a dietitian and fitness trainer may be beneficial.

Diagnosis of Polycystic Ovary Syndrome

Diagnosing PCOS can be a complex process, as it is based on a combination of symptoms, medical history, and tests. There is no single test that confirms the diagnosis of PCOS. Some of the steps doctors can take to diagnose PCOS include:

  • Medical History and Symptoms: The doctor will collect detailed information about symptoms, menstrual history, family history, and other health problems.
  • Physical Exam: A physical exam will be performed to evaluate for external signs of PCOS, such as hirsutism and acne.
  • Blood Tests: Blood tests may be done to measure hormone levels, including hormones such as estrogen, progesterone, androgens, and insulin.
  • Ultrasound: A transvaginal ultrasound may reveal the presence of ovarian cysts. However, not all women with PCOS will have visible cysts on their ovaries.
  • Exclusion of Other Conditions: It is important to rule out other medical conditions that could be causing similar symptoms.

Since PCOS is a heterogeneous condition and symptoms can vary, it is critical to work with a trained healthcare professional to obtain an accurate diagnosis and appropriate treatment plan.

Holistic Approach to the Management of Polycystic Ovary Syndrome

Since PCOS is a complex and multifaceted condition, effective management often requires a holistic approach that addresses both the physical and emotional aspects. Some additional strategies for managing PCOS include:

  • Stress Management: Regular practice of stress management techniques, such as meditation, yoga, and cognitive behavioral therapy, can help reduce stress levels and improve hormonal response.
  • Supplementation: Some supplements, such as inositol and zinc, have shown potential benefits in PCOS management by improving insulin sensitivity and regulating hormone levels.
  • Emotional Support: Diagnosing and managing PCOS can be emotionally challenging. Seeking support from support groups, friends, family, or therapists can be a big help in coping with emotional difficulties.
  • Continuing Education: Education about PCOS and its implications is essential. Women who understand their condition are better equipped to make informed decisions about their health and treatment.


Polycystic Ovary Syndrome is a complex condition that can have a significant impact on women’s health and quality of life. Although there is no definitive cure, early diagnosis and proper management can help manage symptoms and improve long-term health. If you suspect you might have PCOS due to symptoms such as menstrual irregularities, hirsutism, or fertility issues, it’s critical to seek medical advice. Working collaboratively with health professionals and taking a comprehensive approach can give women the tools they need to cope with PCOS and lead full and healthy lives.
