What is polycystic ovary syndrome (PCOS)?
Polycystic ovary syndrome (PCOS) is a common hormonal condition in women of reproductive age, typically beginning in adolescence and affecting the ovaries and other body systems. It manifests as a set of symptoms and affects 8-13% of women of reproductive age, with up to 70% undiagnosed globally (World Health Organization, 2023).
The causes of PCOS aren't clearly established, but patients usually show insulin resistance and hormonal imbalance. Genetics and potentially fetal androgen exposure are also hypothesized as other causes (Rasquin & Mayrin, 2022).
Signs and diagnosis
PCOS diagnosis relies on meeting at least two out of three diagnostic criteria: irregular or missed periods, signs of androgen excess or hyperandrogenism (such as excess facial or body hair, acne, or male-pattern baldness), and the presence of polycystic ovaries on ultrasound. Several signs of PCOS to look out for include (John Hopkins Medicine, 2019; National Institute of Child Health and Human Development, 2022; NHS, 2019):
- Menstrual irregularities which can be in the form of amenorrhea (no menstrual periods) or oligomenorrhea (frequently missed periods)
- Infertility
- Excess hair growth (hirsutism) on the face, chest, belly, or upper thighs
- Severe acne that is difficult to treat
- Obesity, weight gain, especially around the waist
- Oily skin
- Patches of dark, thickened skin (acanthosis nigricans)
- Ovarian abnormalities: enlarged ovaries with cysts
Early detection of this can aid in creating appropriate and effective management treatment plans for patients.
