PCOS and Thyroid Imbalance

Understanding the Connection Between Hormones, Metabolism, and Fertility

If you’ve been diagnosed with Polycystic Ovary Syndrome (PCOS) and still don’t feel like yourself, your thyroid could be part of the problem.

Thyroid imbalance — especially hypothyroidism — often goes hand in hand with PCOS. Together, these conditions can amplify fatigue, weight gain, mood changes, and irregular cycles. Unfortunately, thyroid dysfunction is frequently overlooked in women already diagnosed with PCOS.

At Cheval Wellness, we specialize in identifying and treating both conditions simultaneously, helping restore hormonal balance, energy, and metabolism from the inside out.

The PCOS–Thyroid Connection

Your thyroid gland controls how your body uses energy — influencing metabolism, body temperature, and even reproductive hormones.
When thyroid hormones are too low, every system slows down: metabolism, ovulation, digestion, and even your ability to process other hormones like estrogen and progesterone.

Here’s how thyroid and PCOS interact:

  • Shared Hormonal Pathways: Both involve the hypothalamic-pituitary axis — the communication hub that regulates hormone production.
  • Insulin Resistance: Common in both PCOS and hypothyroidism, leading to stubborn weight gain and fatigue.
  • Inflammation and Autoimmunity: Many women with PCOS also have Hashimoto’s thyroiditis, an autoimmune condition that damages thyroid tissue.
  • Progesterone Deficiency: Low progesterone from irregular ovulation worsens thyroid conversion and balance.

The result is a cycle of hormone confusion that impacts metabolism, mood, and fertility — often leaving women frustrated and unheard.

Signs of Thyroid Imbalance with PCOS

Because PCOS and thyroid disorders share symptoms, the overlap can make diagnosis tricky.

Common symptoms include:

  • Persistent fatigue despite adequate sleep
  • Difficulty losing weight or unexplained weight gain
  • Dry skin, brittle nails, or hair thinning
  • Brain fog and low mood
  • Irregular or absent periods
  • Feeling cold easily
  • Slowed digestion or constipation
  • Infertility or early miscarriage

If these sound familiar, it’s essential to test your thyroid function and antibodies — not just TSH, but Free T3, Free T4, and TPO antibodies for a full picture.

Our Thyroid Optimization Approach for PCOS

At Cheval Wellness, we don’t just treat lab numbers — we treat the person behind them.
Your care begins with comprehensive lab work that evaluates thyroid, adrenal, and reproductive hormones together, because all three systems influence each other.

1. Functional Thyroid Testing

  • TSH (Thyroid-Stimulating Hormone): Your brain’s signal to the thyroid gland
  • Free T3 & Free T4: Active thyroid hormones responsible for energy and metabolism
  • Reverse T3: To identify conversion issues caused by stress or inflammation
  • Thyroid Antibodies (TPO, Tg): To screen for Hashimoto’s or autoimmune thyroiditis

These results allow us to understand whether your thyroid is underactive, sluggish in conversion, or being affected by inflammation or stress.

2. Restoring Thyroid Function Naturally

Depending on your test results, your personalized thyroid plan may include:

  • Thyroid Medication Optimization: Low-dose or combination therapy when medically indicated
  • Nutritional Support: Selenium, zinc, and iodine balance to aid thyroid hormone conversion
  • Adrenal Balancing: Cortisol and DHEA management to reduce hormone disruption
  • Stress & Sleep Optimization: Because chronic stress can blunt thyroid hormone conversion

When thyroid and adrenal balance are restored, metabolism naturally improves — and PCOS symptoms often subside as a result.

3. Balancing Reproductive Hormones

Because thyroid dysfunction can alter estrogen and progesterone metabolism, we also assess whether Bioidentical Hormone Therapy (BHRT) is beneficial for restoring hormonal harmony.
This may include gentle progesterone support, thyroid-regulating nutrients, or adjustments to your BHRT plan if you’re already on hormone therapy.

4. Supporting Metabolism and Weight

Thyroid and insulin resistance are deeply intertwined. We integrate thyroid care into your weight management plan through:

  • GLP-1 Weight Loss Medications (Semaglutide or Tirzepatide)

  • Metabolism-Boosting Injections such as MICC, Lipo Plus, and B12

  • Anti-inflammatory nutrition plans tailored to PCOS and thyroid health

5. Fertility and Menstrual Regularity

An underactive thyroid can interfere with ovulation, cause luteal phase defects, and increase miscarriage risk.
By optimizing thyroid and progesterone levels together, many women experience:

  • Regular cycles
  • Improved egg quality
  • Better implantation success
  • Healthier early pregnancy outcomes

Expected Results

When thyroid balance is restored, you may notice:

  • More energy and better focus
  • Steady weight loss progress
  • Improved mood and mental clarity
  • Regular, healthy menstrual cycles
  • Reduced bloating and water retention
  • Stronger hair, skin, and nails

These changes don’t just transform how you look — they change how you feel.
