Polycystic ovary syndrome how to diagnose
Polycystic ovary syndrome how to diagnose Polycystic ovary syndrome (PCOS) is a common hormonal disorder affecting women of reproductive age. It is characterized by a combination of symptoms and signs that can vary widely among individuals, making diagnosis a nuanced process. Early and accurate diagnosis is essential for managing the condition effectively and preventing long-term complications such as infertility, diabetes, and cardiovascular issues.
The first step in diagnosing PCOS begins with a detailed medical history. A healthcare provider will inquire about menstrual patterns, noting irregularities such as infrequent, prolonged, or absent periods. They will also ask about symptoms like excessive hair growth (hirsutism), acne, weight gain, and thinning hair on the scalp. Additionally, questions about family history and lifestyle factors help provide context and identify potential genetic predispositions.
A thorough physical examination follows, focusing on signs of hormonal imbalance. The clinician may check for excessive hair growth in areas like the face, chest, and abdomen, as well as skin issues such as acne and darkened patches (acanthosis nigricans). The doctor also measures body mass index (BMI) to assess obesity, which is commonly associated with PCOS. Sometimes, physical signs like enlarged ovaries or other reproductive anomalies can be noted through ultrasound. Polycystic ovary syndrome how to diagnose
Laboratory tests are crucial for a definitive diagnosis. The primary blood tests include hormone panels measuring levels of luteinizing hormone (LH), follicle-stimulating hormone (FSH), testosterone, and androgens. Elevated LH relative to FSH, along with increased androgen levels, often suggests PCOS. Additionally, insulin resistance, a common feature of PCOS, can be assessed through fasting glucose and insulin levels. Lipid profiles may also be checked to evaluate cardiovascular risk.

Imaging studies, specifically transvaginal ultrasound, play a significant role in diagnosis. This imaging technique allows visualization of the ovaries to identify characteristic features of PCOS, such as multiple small cysts—often described as a “string of pearls” appearance—and increased ovarian volume. It is important to note that the presence of polycystic ovaries alone does not confirm PCOS, as some women may have cystic ovaries without the syndrome. Therefore, ultrasound findings are combined with clinical and biochemical data. Polycystic ovary syndrome how to diagnose
Polycystic ovary syndrome how to diagnose The diagnostic criteria for PCOS have evolved over time. The Rotterdam criteria, widely accepted by experts, require the presence of at least two of the following three features: irregular or absent ovulation, clinical or biochemical signs of hyperandrogenism, and polycystic ovaries on ultrasound. Importantly, other conditions that mimic PCOS—such as thyroid disorders, hyperprolactinemia, and congenital adrenal hyperplasia—must be ruled out through appropriate testing.

Since symptoms can overlap with other conditions, a multidisciplinary assessment ensures accurate diagnosis and tailored treatment strategies. Recognizing the signs early can improve outcomes, helping women manage symptoms and reduce risks associated with the disorder.
