Polycystic ovary syndrome (PCOS) is a hormonal condition that affects how the ovaries function. It is commonly associated with irregular menstrual periods, higher levels of certain hormones called androgens, and changes in the appearance of the ovaries.
PCOS can affect women differently. Some experience irregular or absent periods, while others may notice acne, increased facial or body hair, thinning scalp hair or difficulty getting pregnant. Not everyone with PCOS experiences the same symptoms.
What causes PCOS?
The exact cause is not fully understood. However, genetics, hormonal changes and insulin resistance may contribute to its development. Insulin resistance occurs when the body’s cells do not respond effectively to insulin, which can lead to higher insulin levels.
PCOS is not simply a condition of the ovaries, and it can affect other aspects of health, including blood sugar regulation and cholesterol levels.
How is PCOS diagnosed?
There is no single test that confirms PCOS. A healthcare professional may review menstrual history, symptoms and medical history, conduct blood tests and, where appropriate, request an ultrasound. Other conditions that cause similar symptoms may also need to be ruled out.
Can PCOS be managed?
Although there is no permanent cure, symptoms can often be managed. Treatment depends on individual needs and may include lifestyle changes, medication to regulate periods, treatment for acne or excess hair growth, or fertility support.
A diagnosis of PCOS does not mean that pregnancy is impossible or that every woman will develop complications. Regular medical reviews can help monitor associated health risks.
Understanding PCOS makes it easier to recognize symptoms and seek appropriate medical advice rather than relying on assumptions or unverified treatments.
