Understanding the Link Between Blood Sugar and Hormone Imbalance

Written By Savannah Garth

You’ve likely heard that blood sugar is important for diabetes—but did you know it’s also crucial for hormone balance?

At Coastal Health & Vitality, we often find that symptoms like fatigue, cravings, PMS, or stubborn weight gain stem from poor blood sugar regulation—which throws off your entire endocrine system.

How Blood Sugar Affects Hormones:

1. Insulin Resistance & Estrogen Dominance

When cells stop responding to insulin, estrogen clearance slows, leading to estrogen dominance and symptoms like bloating, mood swings, and heavy periods.

2. Cortisol Spikes from Sugar Crashes

High sugar intake followed by dips causes the body to produce cortisol, disrupting the balance of progesterone, testosterone, and thyroid hormones.

3. PCOS & Metabolic Dysfunction

For women with Polycystic Ovary Syndrome, blood sugar dysregulation drives high androgens, irregular cycles, and weight gain.

4. Thyroid Suppression

Fluctuating glucose impacts the thyroid, leading to slower metabolism, fatigue, and hair thinning.

Signs of Blood Sugar-Driven Hormone Imbalance:

  • Cravings for sugar or carbs

  • Midday energy crashes

  • Weight gain, especially in the belly

  • Irritability or mood swings between meals

  • Sleep disruptions

  • Hormonal acne or irregular periods

How We Help You Balance Both:

  • Glucose and hormone testing to identify imbalances

  • Low-glycemic food plans to stabilize insulin

  • BHRT, if needed, to correct hormone dysfunction

  • Supplementation (like magnesium, inositol, or berberine)

  • Lifestyle coaching to support cortisol and metabolic repair
