Polycystic ovary syndrome or PCOS is a common hormonal disorder that affects women of reproductive age. According to recent estimates, PCOS impacts 1 in 10 women worldwide. While PCOS symptoms can be confusing, getting an accurate diagnosis is crucial for addressing underlying health issues and managing the condition effectively. This article aims to provide a comprehensive overview of PCOS diagnostic criteria and processes.
Diagnostic Criteria for PCOS
The diagnosis of PCOS is based on guidelines established by the Rotterdam consensus in 2003. According to these criteria, a woman can be diagnosed with PCOS if she exhibits two of the following three features:
Irregular periods: Women with PCOS often experience irregular, infrequent or prolonged menstrual cycles. This is known as oligomenorrhea or amenorrhea and is usually caused by hormonal imbalances.
Clinical and/or biochemical signs of hyperandrogenism: Signs include excess body and facial hair (hirsutism), acne, skin pigmentation (darkening), virilization or high androgen levels in the blood.
Polycystic ovaries: While cysts on the ovaries are not unusual, those with PCOS have a string of pearls appearance with 12 or more follicles measuring 2-9 mm in diameter clustered around the outer edge of each ovary. These ovarian cysts can be detected via pelvic ultrasound.
Having any two of the above symptoms is sufficient for a diagnosis. However, not all women experience the same combination of issues. PCOS presentation can vary significantly from person to person.
Initial Diagnostic Tests
Once PCOS is suspected based on symptoms and medical history, diagnostic testing helps confirm the condition or rule out other causes. Common initial tests may include:
Blood Tests: Tests to measure levels of reproductive hormones like testosterone, DHEAS, prolactin, luteinizing hormone (LH) and follicle-stimulating hormone (FSH) help identify abnormal hormone patterns associated with PCOS. High androgen levels support a diagnosis.
Pelvic Ultrasound: An ultrasound of the ovaries is done to look for polycystic ovaries and detect any ovarian cysts present. Cysts may be clustered around the outer edge of the ovaries in women with PCOS.
Additional Tests
Sometimes additional testing may be required to completely rule out other possible conditions with similar symptoms. These include:
– Thyroid Tests: To check thyroid function since thyroid issues can also cause irregular periods and hormonal imbalances.
– Pregnancy Test: To rule out pregnancy as a cause of missed periods.
– Adrenal Testing: To check for conditions affecting the adrenal glands like congenital adrenal hyperplasia (CAH) which mimic PCOS.
– Liver and Kidney Function Tests: To rule out other medical issues impacting these organs that could resemble PCOS signs.
– Hemoglobin A1C and Glucose Tests: To screen for insulin resistance and risk of diabetes often associated with PCOS.
Getting a Clinical Examination and Detailed History
Diagnosis involves a thorough clinical examination by an ob-gyn or endocrinologist. Doctors evaluate extent of hair growth, acne and skin pigmentation as well as external genitalia for signs of virilization. They also collect a detailed menstrual, medical, family and pregnancy history. This information guides diagnosis and helps rule out other possibilities.
Making a Confirmed Diagnosis
Only after evaluating all clinical features, conduct diagnostic testing and rule out alternative conditions, can a doctor confirm a diagnosis of PCOS. The goal is to determine if a woman meets the Rotterdam criteria and establish the source is not a temporary issue or other medical disorder. A formal diagnosis enables proper management of this complex condition.
Managing PCOS Post Diagnosis
Once diagnosed, PCOS treatment focuses on managing symptoms and reducing health risks. Lifestyle modifications like diet, exercise and stress management form the first line approach. Medications may be prescribed to regulate periods, reduce hair growth or lower high insulin levels and risk of diabetes and heart disease associated with PCOS. Fertility treatments also help women trying to conceive. Regular monitoring by healthcare providers is important to track treatment progress. Overall, an accurate diagnosis helps optimize PCOS management and improve quality of life.
