What is the Connection Between Your Adrenals and Thyroid?

Feeling constantly exhausted, gaining weight, and struggling to concentrate lately? Issues with your adrenal glands and thyroid could be to blame. These two small but mighty endocrine glands work closely together to regulate vital processes in your body. When one falters, it strains the other, creating a ripple effect of hormonal mayhem.

Understanding the complex interplay between your adrenals and thyroid is key to getting to the root of lingering fatigue, stubborn weight gain, and other common health complaints. Read on to learn how these glands impact one another, signs of dysfunction, and ways to support healthy adrenal-thyroid function.

Adrenal and Thyroid Roles in Your Body

First, a quick overview of what each gland does:

  • The adrenal glands—one located above each kidney—secrete hormones like cortisol that control your stress response, blood pressure, energy levels, immunity, and more.
  • Your thyroid—the bowtie-shaped gland in your neck—releases hormones like T3 and T4 that regulate your metabolism, body temperature, heart rate, menstrual cycle, mood, and more.

When these glands are balanced, they work together seamlessly to keep your body and mind firing on all cylinders.

The Stress-Thyroid Connection

Your adrenals and thyroid are part of an intricate network known as the endocrine system. Imbalances in one gland can throw others out of whack. Here’s how chronic stress links your adrenals to thyroid dysfunction:

  • Constant stress activates your adrenals to release cortisol and adrenaline. This floods your body with stimulating hormones.
  • Over time, your adrenal glands become depleted or “fatigued” from overwork. They struggle to keep up with cortisol demands.
  • With your adrenals drained, your thyroid—which requires proper adrenal function—goes into conservation mode. This slows down your metabolism, compounding symptoms of fatigue.
  • High cortisol also inhibits the conversion of inactive T4 thyroid hormone into active T3. Less T3 means hypothyroid symptoms like stubborn weight gain, fatigue, and brain fog.

As you can see, unmanaged stress creates the perfect environment for an underactive thyroid.


Signs Your Adrenals and Thyroid Need Support

Since adrenal and thyroid hormones impact so many bodily processes, symptoms of dysfunction vary widely but often include:

Adrenal imbalance symptoms:

  • Fatigue, especially in the mornings/afternoons
  • Cravings for salty and sweet foods
  • Difficulty handling stress, anxiety, irritability
  • Weight gain, particularly around the waist
  • Low stamina, blood pressure, and blood sugar

Thyroid imbalance symptoms:

  • Fatigue or sluggishness
  • Weight gain or difficulty losing weight
  • Sensitivity to cold temperatures
  • Constipation
  • Dry skin and hair
  • Impaired memory and concentration
  • Depression or mood changes

If you’re experiencing any of these symptoms, get your hormone levels tested to pinpoint imbalances. An integrative or functional medicine practitioner can help interpret results and get to the root cause with proper testing for adrenal fatigue and thyroid disorders.

Nutrition to Support Healthy Adrenal and Thyroid Function

Certain dietary changes can powerfully support your adrenals and thyroid:

For adrenal health:

  • Choose complex carbs like squash and oats. Avoid sugar highs/crashes.
  • Increase intake of magnesium, B vitamins, and vitamin C.
  • Eat nutrient-dense foods and healthy fats like avocado, nuts, and olive oil.
  • Stay hydrated with water and herbal teas.
  • Limit caffeine to one cup per day max.

For thyroid health:

  • Make sure to get enough iodine, selenium, zinc, iron, and vitamin D.
  • Eat plenty of antioxidant-rich fruits and veggies.
  • Avoid inflammatory foods like gluten, dairy, soy, and processed items.
  • Choose hormone-supporting foods like seafood, pumpkin seeds, and probiotic yogurt.

Other Lifestyle Tweaks to Rebalance Adrenals and Thyroid

Diet is just one piece of the hormone puzzle. Try these other holistic ways to support healthy endocrine function:

  • Get 7-9 hours of sleep nightly. Poor sleep strains your adrenals further.
  • Find ways to manage daily stress through yoga, walks, meditation, etc.
  • Exercise moderately but regularly to oxygenate tissues and support metabolism.
  • Take adaptogenic herbs like ashwagandha, rhodiola rosea, or licorice root.
  • Consider nutritional supplements like magnesium, B-complex, or zinc.
  • Address underlying issues like food sensitivities, blood sugar imbalances, and gut health.

Medical Treatments for Adrenal and Thyroid Disorders

If natural remedies aren’t providing enough relief, your doctor may recommend medical hormone treatments like:

  • Levothyroxine for hypothyroidism
  • Liothyronine for underactive thyroid
  • Steroid replacement therapy for adrenal insufficiency
  • Slowly tapering off corticosteroids if adrenal issues are caused by medication overuse

But remember—medication only treats the symptoms. For long-lasting balance, getting to the root cause of dysfunction is key, whether it stems from chronic stress, diet, gut issues, or other factors.

The adrenals and thyroid are intimately linked, and supporting the health of one goes hand in hand with supporting the other. Give your body what it needs to thrive through nourishing foods, stress-balancing practices, and the support of a knowledgeable functional or integrative medicine doctor. With the right comprehensive approach, you can get your hormones back in sync and finally feel your best again.



Supporting healthy adrenal and thyroid function requires a holistic approach focused on balancing stress, nutrition, sleep, and lifestyle factors. Work with a practitioner to get to the root cause of your hormonal issues. Then, give your body the nourishment and care it needs to thrive. You’ll be amazed how much better you feel when your adrenal and thyroid glands are back in sync.
