Relationship Between Estrogen Dominance & Thyroid Disease

You’ve made some lifestyle changes to improve your thyroid condition, yet your symptoms are not budging. You want to know why. I hear you. Let me take off the detective work off your shoulder. 

The missing problem may be too much estrogen in your body. You may not be aware that one of the contributing factors of your thyroid disease is another hormonal issue, estrogen dominance. Once you understand this, you can finally address the root cause and support your thyroid naturally.

In this article, you will learn about estrogen dominance. You will understand its symptoms, its main causes, and its connection to thyroid disease. I will share with you my top tips to resolve estrogen dominance and thyroid disease naturally.

What Is Estrogen Dominance

Estrogen and progesterone are the two primary female sex hormones. Under healthy circumstances, they work together in a healthy rhythm and are responsible for your female cycle. Together with your thyroid and adrenal hormones, they are critical for your hormonal health.

Even though estrogen and progesterone are sex hormones, they are responsible for much more than reproductive health. Estrogen is critical for the reproductive cycle and childbearing in women, but it’s also important for bone health, healthy levels of cholesterol, brain health, mood, metabolism, skin health, thyroid health, and overall hormonal function. Progesterone helps to lower inflammation, balance the nervous system, and stimulate your thyroid hormone. When your estrogen and progesterone levels get out of balance it affects your entire body.

Estrogen dominance happens when estrogen and progesterone get out of balance. This may happen because your body is making too much estrogen resulting in estrogen excess. In other cases, progesterone levels drop too low leading to imbalance and estrogen dominance. In both cases, estrogen becomes the dominant hormone resulting in a variety of symptoms (1).

Symptoms of estrogen dominance include:

  • Pre-menstrual symptoms (PMS)
  • Endometriosis
  • Fatigue
  • Infertility
  • Miscarriages
  • Weight gain
  • Hot flashes
  • Menstrual cramps
  • Headaches
  • Decreased libido
  • Depression and mood imbalance
  • Excessive menstruation
  • Ovarian cysts
  • Uterine fibroids
  • Fibrocystic breasts
  • Tender breasts
  • Brain fog
  • Insulin resistance
  • Thyroid problems
  • Autoimmunity
  • Cancer

Estrogen Dominance and Thyroid Disease

Your body is a holistic system. Nothing happens in isolation. It’s not surprising that when one hormone is out of balance, it affects other hormones as well. Estrogen dominance can affect your thyroid hormones and contribute to Hashimoto’s disease, thyroid cancer, and other thyroid conditions (2, 3)

Your body is always seeking balance. Estrogen and progesterone work the opposite of each other to achieve this equilibrium, which means that they also affect your thyroid hormones in the opposite way. While estrogen helps to suppress the thyroid hormone, progesterone stimulates it. If your body has too much estrogen and too little progesterone, it can lead to overstimulation and overproduction of thyroid hormone resulting in hypothyroidism. 

Researchers have found that excess estrogen may lead to the elevation of the thyroid-stimulating hormone (TSH) and thyroid antibodies. Too much estrogen may also increase inflammation, compromise your immune system, and increase the production of anti-thyroid peroxidase (anti-TPO) antibodies contributing to autoimmune thyroid conditions, such as Hashimoto’s disease (4, 5)

Main Causes of Estrogen Dominance

Estrogen dominance may be caused by a number of dietary, lifestyle, and environmental factors. Let’s look at some of the top contributing factors.

Poor Diet

One of the top causes of estrogen dominance is diet. Commercially raised animal products have been injected with hormones and non-organic conventional produce is full of pesticides, herbicides, and fungicides. Packaged processed foods are high in artificial ingredients and chemicals. These hormones, pesticides, and other chemicals are endocrine disruptors that can seriously interfere with your hormonal health (6).

Gut Imbalance

In a healthy gut microbiome, an enzyme called beta-glucuronidase helps to regulate circulating estrogen in your body. If your gut flora is out of balance, these enzymes won’t be able to metabolize estrogen efficiently increasing your risk of estrogen dominance and related issues (7).

Cleaning and Personal Care Products

Conventional cleaning products, soaps, shampoo, toothpaste, lotions, and cosmetics are loaded with chemicals. Parabens, phthalates, and other common compounds in these products all have estrogen activity and can lead to estrogen dominance (8).

BPA and Plastics

From water bottles to food and storage containers, plastics are everywhere. Unfortunately, these plastics contain hormone-mimicking xenoestrogens that can disrupt your hormonal balance and lead to estrogen dominance (9).

Heavy Metals

Municipal tap water, aluminum pots and pans, old paint residue, dental amalgam fillings, and conventional cosmetics are places where heavy metals may hide. Mercury, lead, cadmium and other heavy metals, however, all possess estrogen-mimicking and endocrine-disrupting properties. (10).

Body Fat 

Your body fat is the place where estrogen xenoestrogens get absorbed and stored. Excess estrogen also urges your body to create more fat cells further feeding into the cycle of excess fat and estrogen dominance (11).

Hormone Replacement Therapy (HRT) and Birth Control

Oral contraceptives and hormone replacement therapy medication contain a lot of synthetic estrogens. Without the necessary progesterone to balance it out, taking such medication increases imbalance and the risk of estrogen dominance.

Chronic Stress

When you are chronically stressed, your body produces excess cortisol to try to respond to and cope with the constant stress. Progesterone is the precursor of cortisol and increased demand for cortisol can result in estrogen dominance and hormonal imbalance (12, 13).

Natural Solutions for Estrogen Dominance and Thyroid Disease

Estrogen dominance and thyroid disease are certainly concerning. The good news is that you can reduce estrogen dominance and repair thyroid issues naturally by following a few simple steps.

Improve Your Food

Eliminate inflammatory foods that may contain hidden estrogens, including conventional meat and dairy and non-organic food. Choose organic, hormone-free, grass-fed, and pasture-raised animal products and organic produce free from pesticides and fertilizers. 

Reduce Chemical Exposure

Remove conventional cleaning and beauty products and use organic, natural, and homemade products instead. Replace plastic with glass or stainless steel bottles and containers. Filter your water. 

Reduce Stress

Lower your stress levels. Get 7 to 9 hours of sleep at night. Try yoga, meditation, breathwork, journaling, relaxation exercises to cope with stress better. Surround yourself with positive people and activities.

Take a Liver Support Supplement

Try Optimal Reset Liver Love. This supplement is a powerful blend of botanical and mushroom extracts and N-Acetyl-L-Cysteine (NAC), a derivative of the amino acid cysteine. It supports healthy liver function and allows optimal estrogen detoxification.

Take a Thyroid Support Supplement

For thyroid-support, I recommend Optimal Reset Ultimate Thyroid Support. This supplement was designed to support your thyroid with the help of non-stimulating adaptogenic botanical American ginseng and essential vitamins, minerals, and other nutrients.

Try a 30-Day Thyroid Reset

The 30-day Thyroid Reset Plan is an all-natural treatment plan, which includes a highly effective and easy-to-follow 30-day reset diet with foods that resolve estrogen dominance and support healthy thyroid function. My book, The 30-Day Thyroid Reset Plan: Disarming the 7 Hidden Triggers That are Keeping You Sick, outlines this plan carefully. It also includes dozens of delicious thyroid-supporting recipes.

Get the Thyroid Reset Kit
