Understanding PCOS: Causes, Symptoms, and Why Early Treatment Matters

Updated: Aug 26, 2025

Polycystic Ovarian Syndrome (PCOS) is a common condition affecting 5–10% of women, where the ovaries don't function normally, often leading to fertility issues and other health complications linked to elevated male hormone levels.


What Causes PCOS?

The exact cause of PCOS isn’t fully understood, but it likely results from a combination of genetic and environmental factors. Elevated androgen levels can disrupt ovulation and the menstrual cycle, while insulin resistance, common among women with PCOS, may boost androgen production further. Inflammation and fetal exposure to excess male hormones may also contribute to developing the condition.


Common Signs and Symptoms of PCOS

Women with PCOS often experience missed periods, excess facial and body hair, hair thinning, acne, and difficulty conceiving. PCOS is also linked to serious health risks, including type 2 diabetes, hypertension, high cholesterol, heart disease, obesity, and obstructive sleep apnea (OSA).


PCOS and Obesity: A Complicated Relationship

The relationship between PCOS and obesity is complex: PCOS can contribute to weight gain, and obesity can worsen PCOS symptoms. Between 38–88% of women with PCOS are overweight or obese, with insulin resistance playing a major role. Even modest weight loss—around 5%—can significantly improve symptoms and overall health.


How PCOS Increases the Risk of Sleep Apnea

Women with PCOS have over twice the risk of developing OSA compared to those without PCOS, regardless of their weight. Hormonal imbalances, along with excess weight, can contribute to breathing disruptions during sleep. Managing weight and addressing hormonal issues can improve both PCOS and sleep apnea symptoms.


How is PCOS Diagnosed?

PCOS is diagnosed through a combination of medical history, symptom review, physical examination, hormone testing, and sometimes pelvic ultrasound. Early diagnosis and management are critical to improve symptoms, protect fertility, and lower the risk of complications like heart disease, diabetes, uterine cancer, and pregnancy problems.


PCOS Treatments: Improving Symptoms and Long-Term Health

Although there’s no cure for PCOS, treatments focus on managing symptoms and reducing long-term risks. Lifestyle changes such as healthy eating, regular exercise, weight management, and quitting tobacco use are key. Hormonal therapies, insulin-sensitizing medications like Metformin, and treatments for skin and hair symptoms can also help.


Even small, sustainable changes can have a major impact on managing PCOS and improving quality of life.
