Learn · About PCOS/PMOS

PCOS is common, complex and real.

Polycystic ovary syndrome (PCOS), now also called polyendocrine metabolic ovarian syndrome (PMOS), is a lifelong hormonal and metabolic condition that can affect people with ovaries. It's one of the most common endocrine disorders worldwide, and one of the most misunderstood.

The basics

What is PCOS?

PCOS is a condition rooted in hormonal dysregulation and metabolic imbalance. While the name suggests ovarian cysts, many people with PCOS never develop cysts at all, and many people without PCOS do.

PCOS exists on a spectrum. Symptoms may range from mild to severe and can shift over time with age, stress, pregnancy or menopause.

At its core, PCOS involves:

  • Disrupted communication between the brain, ovaries and adrenal glands
  • An imbalance of reproductive and metabolic hormones
  • Altered ovulation patterns
  • Systemic inflammation and insulin dysfunction in many cases
Hormones and metabolism

Hormonal and metabolic imbalance in PCOS.

One of the defining features of PCOS is elevated androgen levels, often called "male-type hormones," though all bodies naturally produce them. When these hormones are higher than typical, they can interfere with ovulation and contribute to acne, excess hair growth or scalp hair thinning.

Insulin resistance (common, not universal)

PCOS is closely linked to insulin resistance, where the body struggles to use insulin effectively. This can lead to:

  • Increased insulin levels
  • Increased androgen production
  • Difficulty managing weight
  • Increased inflammation

Important nuance

Not everyone with PCOS has insulin resistance, but for many it plays a significant role in how symptoms show up. PCOS care should always be individualized.

PCOS is not caused by lifestyle choices.

PCOS is not caused by poor diet, lack of exercise or weight. It is a medical condition influenced by genetics, hormones and metabolic function.

Lifestyle interventions may be used as supportive tools to manage symptoms, not as a cure and not as a measure of personal responsibility.

Long-term health

Health risks associated with PCOS.

Because PCOS affects multiple systems in the body, it's associated with long-term health risks, especially when symptoms go unmanaged or unrecognized.

Metabolic & cardiovascular

  • Insulin resistance and type 2 diabetes
  • Prediabetes
  • High cholesterol
  • High blood pressure
  • Increased risk of heart disease

Reproductive & hormonal

  • Chronic anovulation
  • Irregular or absent menstrual cycles
  • Increased risk of endometrial hyperplasia due to prolonged lack of ovulation

Inflammatory & sleep-related

  • Chronic low-grade inflammation
  • Sleep apnea, particularly with insulin resistance

Mental health

  • Anxiety
  • Depression
  • Disordered eating
  • Body image distress

Mental health challenges are common in PCOS and are often compounded by delayed diagnosis, medical dismissal and societal stigma. If you're struggling, support is available.

Every life stage

Living with PCOS.

Living with PCOS means managing a condition that can evolve across life stages, from adolescence to adulthood and beyond. It can affect:

Energy levels Mood and emotional health Self-esteem Relationships Family planning decisions Long-term health monitoring

Because PCOS is lifelong, care often requires a holistic, individualized approach that considers physical health, mental well-being and quality of life, not just symptom suppression.

Care

PCOS management is not one-size-fits-all.

There is no single treatment plan that works for everyone with PCOS. Symptom management may change over time and often combines medical care, education and supportive strategies.

Explore treatment options
  • Understanding your body and symptoms
  • Addressing metabolic health when relevant
  • Supporting hormonal balance
  • Prioritizing mental and emotional well-being
  • Advocating for informed, respectful care

PCOS does not end with the reproductive years. Symptoms and risks may continue or shift during perimenopause and menopause, so ongoing education and monitoring remain important throughout life.
