How is Polycystic Ovary Syndrome diagnosed?

Polycystic Ovary Syndrome (PCOS) is a common hormonal disorder that affects women of reproductive age. It is characterized by a combination of symptoms such as irregular menstrual cycles, excess androgen levels, and the presence of multiple cysts on the ovaries. Diagnosing PCOS involves a comprehensive evaluation of a woman's medical history, physical examination, and specific diagnostic tests.

Medical History

A crucial step in diagnosing PCOS is obtaining a detailed medical history from the patient. The healthcare provider will ask about the patient's menstrual cycles, including the regularity, duration, and any associated symptoms such as pain or heavy bleeding. They will also inquire about other symptoms commonly associated with PCOS, such as acne, excessive hair growth (hirsutism), weight gain, and mood changes. Additionally, the healthcare provider will ask about the patient's family history of PCOS or other hormonal disorders.

Physical Examination

During the physical examination, the healthcare provider will assess various aspects of the patient's health. They will measure the patient's blood pressure, body mass index (BMI), and waist circumference. These measurements help determine if the patient is overweight or obese, as excess weight is often associated with PCOS. The healthcare provider will also examine the patient's skin for signs of acne, excess hair growth, or darkened patches (acanthosis nigricans), which can be indicative of insulin resistance.

Diagnostic Tests

While medical history and physical examination provide valuable information, specific diagnostic tests are necessary to confirm a PCOS diagnosis. These tests may include:

1. Blood Tests: Blood samples are taken to measure hormone levels, including follicle-stimulating hormone (FSH), luteinizing hormone (LH), testosterone, and sex hormone-binding globulin (SHBG). Elevated levels of LH and testosterone, along with low levels of FSH and SHBG, are commonly observed in women with PCOS.



2. Pelvic Ultrasound: A pelvic ultrasound is performed to visualize the ovaries and assess their size and appearance. In PCOS, the ovaries often appear enlarged and contain multiple small cysts. However, the presence of cysts alone is not sufficient for a PCOS diagnosis, as other conditions can also cause ovarian cysts.



3. Other Tests: In some cases, additional tests may be conducted to rule out other potential causes of the symptoms. These tests may include thyroid function tests, glucose tolerance tests, and lipid profile assessments.

Diagnostic Criteria

Diagnosing PCOS involves considering various factors, including the patient's symptoms, medical history, physical examination findings, and the results of diagnostic tests. The diagnostic criteria for PCOS vary slightly between different medical organizations, but the most commonly used criteria are those established by the Rotterdam Consensus in 2003. According to these criteria, a woman may be diagnosed with PCOS if she meets at least two of the following three criteria:

1. Irregular or Absent Menstrual Cycles: The patient experiences infrequent or absent menstrual periods, indicating ovulation problems.



2. Hyperandrogenism: Clinical signs of excess androgen levels, such as acne, hirsutism, or elevated testosterone levels, are present.



3. Polycystic Ovaries: The ultrasound examination reveals the presence of multiple small cysts on the ovaries.

It is important to note that PCOS is a complex condition, and the diagnosis should be made by a qualified healthcare professional. The symptoms and diagnostic criteria may vary from person to person, and a thorough evaluation is necessary to ensure an accurate diagnosis.
