PCOS in Young Women: Clinical Presentation and Management Approaches

Polycystic Ovary Syndrome (PCOS) is a common, heterogeneous endocrine disorder affecting approximately 6–20% of women of reproductive age, with onset frequently occurring during adolescence and early adulthood. It is characterized by a constellation of clinical, biochemical, and metabolic abnormalities including hyperandrogenism, ovulatory dysfunction, and polycystic ovarian morphology. In young women, PCOS presents unique diagnostic and therapeutic challenges due to physiological overlap with normal pubertal changes. Beyond reproductive implications, PCOS is strongly associated with insulin resistance, metabolic syndrome, type 2 diabetes mellitus, and psychological disturbances. This article provides a comprehensive overview of PCOS with emphasis on clinical presentation in young women and evidence-based management strategies, integrating lifestyle, pharmacological, and long-term preventive approaches.

It is a heterogeneous, multisystem condition characterized by varying degrees of hyperandrogenism, ovulatory dysfunction, and polycystic ovarian morphology, often accompanied by metabolic and psychological disturbances. The syndrome not only affects reproductive health but also has far-reaching implications for metabolic, cardiovascular, and mental well-being. First described by Stein and Leventhal in 1935, PCOS has since evolved from being considered a purely gynecological disorder to a complex endocrine–metabolic syndrome. Its etiology is multifactorial, involving genetic predisposition, environmental influences, and lifestyle factors, with insulin resistance playing a central pathogenic role. Hyperinsulinemia contributes to increased ovarian androgen production and decreased sex hormone-binding globulin (SHBG), thereby exacerbating clinical manifestations. The diagnosis of PCOS remains challenging, especially in young women, due to the overlap between normal pubertal physiological changes and pathological features of the syndrome. The widely accepted Rotterdam criteria (2003) require the presence of at least two of the following: oligo/anovulation, clinical or biochemical hyperandrogenism, and polycystic ovarian morphology on ultrasound, after excluding other etiologies. However, in adolescents, diagnostic caution is necessary to avoid overdiagnosis, as irregular menstrual cycles and multifollicular ovaries may be part of normal maturation. Clinically, PCOS in young women often presents with menstrual irregularities, acne, hirsutism, and weight gain, which can significantly affect quality of life and psychological health. Additionally, early manifestations of insulin resistance, dyslipidemia, and obesity may predispose these individuals to long-term complications such as type 2 diabetes mellitus and cardiovascular disease. Given its chronic nature and wide spectrum of clinical manifestations, PCOS requires a comprehensive, individualized, and multidisciplinary management approach. Early identification and timely intervention are crucial in mitigating both immediate symptoms and long-term health risks. This article aims to provide a detailed overview of PCOS in young women, focusing on its clinical presentation and evidence-based management strategi es.
