Signs You May Have Undiagnosed PCOS

Polycystic Ovary Syndrome (PCOS) is one of the most common endocrine disorders affecting women of reproductive age, yet it is often misdiagnosed—or worse, never diagnosed at all. An estimated one in ten women live with PCOS, but many remain unaware because their symptoms appear unrelated or are mistakenly attributed to other conditions.

Dr. Minoos Hosseinzadeh, Founder and Medical Director of Fertility Institute of San Diego, explains:

“PCOS is not a one-size-fits-all condition. Some women have irregular periods, others present with acne or weight changes. Without a full evaluation, these subtle clues can easily be overlooked.”

How to Recognize the Early Signs

Many patients ask, “Can you have PCOS without knowing?” The answer is yes. Some women discover their diagnosis only after experiencing difficulty getting pregnant.

  • Irregular or absent menstrual cycles
  • Excess androgens leading to acne or unwanted facial hair
  • Weight gain, especially around the midsection
  • Hair thinning or loss from the scalp
  • Ovarian cysts visible on ultrasound

Why Early Recognition Matters

When left undiagnosed, PCOS can lead to serious health risks, such as insulin resistance, type 2 diabetes, and hypertension.

“I always encourage patients not to ignore irregular cycles or persistent symptoms. Early detection allows us to intervene sooner, reducing long-term complications and improving fertility outcomes.” — Dr. Hosseinzadeh

Who Is at Risk?

  • Family history of PCOS or type 2 diabetes
  • Early onset of puberty
  • Obesity or rapid weight fluctuations
  • History of irregular periods during adolescence

When to Seek Help

If you’ve gone more than three months without a period, struggle with sudden weight gain, or notice hair loss due to hormonal imbalance, it’s time to see a doctor.

Symptoms in Detail

  • Menstrual irregularities: Skipping cycles or heavy bleeding episodes
  • Excess androgen activity: Acne, oily skin, hirsutism
  • Ovarian follicles: Multiple cysts visible on pelvic ultrasound
  • Metabolic indicators: Cravings, fatigue, or elevated insulin
  • Emotional health: Anxiety, depression, mood swings

Causes and Underlying Mechanisms

PCOS originates in hormonal imbalance. Excess androgens disrupt ovulation, leading to irregular cycles and multiple cysts. Insulin resistance worsens the condition over time.

Risk Factors and Complications

  • Infertility due to chronic anovulation
  • Endometrial hyperplasia and cancer
  • Metabolic syndrome and cardiovascular disease
  • Sleep apnea and chronic fatigue

Prevention and Proactive Management

  • Balanced nutrition with low-glycemic foods
  • Regular exercise
  • Mindfulness and stress reduction
  • Routine checkups for hormone and metabolic panels

Types of Treatment Available

  • Lifestyle: Weight management, diet, exercise
  • Medication: Metformin, hormonal contraceptives
  • Fertility Treatments: Ovulation induction, IVF
  • Holistic strategies: Acupuncture, stress reduction

“Managing PCOS is not only about fertility. It’s about creating sustainable health outcomes for each woman’s unique journey.” — Dr. Hosseinzadeh

Costs and Considerations

Lifestyle changes may be low-cost, but medications and fertility treatments can be more expensive. Choose clinics that offer transparent pricing and tailored care plans.
