What is PCOS? A Complete Guide to Polycystic Ovary Syndrome

Introduction

Polycystic Ovary Syndrome (PCOS) affects millions of people with ovaries around the world and remains one of the most common hormone-related disorders. If you’re asking, “What is PCOS?”, you’re not alone. Understanding PCOS and how it impacts your hormones, metabolism, menstrual cycle and overall health is the first step toward mastering your symptoms. In this article we’ll explain what PCOS is, its symptoms, causes, health risks, how it’s diagnosed and the lifestyle changes that help manage it — especially through diet and workouts designed for PCOS.

What is PCOS?

PCOS stands for Polycystic Ovary Syndrome — a hormonal disorder that affects how the ovaries, ovaries’ follicles and endocrine system function. Hopkins Medicine+2Cleveland Clinic+2Despite the name, you don’t always have visible ovarian “cysts” to have PCOS. Rather, what you do see are hormone imbalances such as elevated androgens (male-type hormones) and irregular ovulation. Mayo Clinic+1In simple terms: with PCOS your body is giving your ovaries mixed signals — ovulation may not happen regularly, hormone levels may shift, and this creates systemic ripple effects throughout your entire body.

Why “PCOS” Matters: The Bigger Picture

PCOS isn’t only about irregular periods. Many people don’t realize the full scope of this condition’s impact, which includes:

• Hormone imbalance: High androgen levels, low progesterone, insulin resistance. Cleveland Clinic

• Reproductive challenges: Irregular or absent ovulation, fertility issues. World Health Organization+1

• Metabolic effects: Many people with PCOS experience insulin resistance, weight gain, and a higher risk of type 2 diabetes. NCBI+1

• Long-term health risks: Mood disorders, cardiovascular issues, endometrial changes if untreated. UpToDate+1

Recognizing PCOS early and managing it proactively can make a major difference for your health – and that’s why education matters so much.

What Are the Common PCOS Symptoms?

If you’re wondering “Could I have PCOS?”, here are the most common signs to look for:

• Irregular, infrequent or long menstrual cycles. Mayo Clinic

• Signs of excess androgens: acne, unwanted hair growth (hirsutism), thinning scalp hair. Cleveland Clinic

• Weight gain or difficulty losing weight, especially around the abdomen.

• Dark patches of skin (acanthosis nigricans) or small skin tags. Cleveland Clinic

• Infertility or difficulty conceiving.

• Mood changes, fatigue, poor sleep, and sometimes sleep apnea.

It’s important to note that every person with PCOS is different — some may only have mild symptoms, others more pronounced ones. Diagnosis is based on a pattern, not just one symptom alone.

What Causes PCOS?

The exact cause of PCOS is still being researched. Several key factors play a role:

• Genetics: PCOS tends to run in families, indicating a genetic component. Verywell Health

• Insulin resistance: Many people with PCOS have insulin resistance even without being overweight. NCBI+1

• Hormonal imbalance: Higher levels of androgens, altered LH/FSH ratios, disrupted ovulation cycles. Hopkins Medicine

• Lifestyle & environment: Diet, exercise, stress, and body composition all influence how PCOS shows up and how severe it becomes.

How is PCOS Diagnosed?

Typical criteria for diagnosing PCOS often include:

• Irregular ovulation or absent ovulation

• Clinical or biochemical signs of androgen excess

• Polycystic ovaries visible on ultrasound in some cases NCBIYour doctor will rule out other conditions that mimic PCOS (thyroid issues, adrenal disorders) and may run tests like hormone panels, glucose/insulin levels, and ultrasound exams.

PCOS Treatment & Management: What Works

While there’s no cure for PCOS, the good news is: you can manage it — especially through lifestyle habits. Here’s how:

1. Nutrition & PCOS friendly diet

   • Focus on whole foods, low-glycemic carbohydrates, plenty of fiber and balanced protein.

   • Manage insulin levels by avoiding frequent sugar spikes.

2. Workouts tailored for PCOS

   • Strength training, core activation, mobility, and low-impact cardio are all parts of an effective PCOS workout program.

   • Consistency matters more than the intensity.

3. Change your mindset

   • Handling stress, sleep and hormonal health go hand in hand. High cortisol worsens PCOS symptoms.

4. Medical support

   • In some cases your doctor may recommend medications (like metformin or hormonal contraceptives) or fertility support depending on your goals.

     
     

Why Exercise + Diet Are Key for PCOS

For those managing PCOS, a balanced workout routine and diet play powerful roles in symptom relief:

• Exercise improves insulin sensitivity, helping reduce the high insulin levels often present in PCOS.

• Strength + stability work supports hormone-healthy muscle mass and helps regulate metabolism.

• Low-impact cardio and mobility help manage stress hormones (like cortisol) — crucial for hormonal balance.

• A PCOS-specific exercise plan avoids over-training, which can spike cortisol and negatively impact hormones.
