In our modern world, hormonal imbalances seem increasingly common for both men and women, with symptoms ranging from fatigue and mood swings to digestive issues and unexplained weight gain. While various factors can contribute to these disruptions, one of the more pervasive yet lesser-known contributors is estrogen dominance, fueled largely by synthetic compounds called xenoestrogens. Let's take a look at how estrogen as a whole can cause major hormone and health disruption.
Understanding Estrogen and Xenoestrogens
Estrogen in the Body
Estrogen is a natural hormone present in both men and women, though at different levels. It’s essential for various functions, such as regulating menstrual cycles in women, supporting bone density, and influencing mood and libido in both sexes. The body maintains a delicate balance of estrogen in conjunction with other hormones like progesterone, testosterone, and cortisol to support optimal health.
Xenoestrogens: The Chemical Mimics
Xenoestrogens, often referred to as "environmental estrogens," are synthetic compounds found in everyday products like plastics, pesticides, cosmetics, and even food. Their chemical structure is similar enough to estrogen that the body can mistake them for the real hormone. These compounds bind to estrogen receptors, which can lead to a phenomenon called "estrogen dominance," where the presence of too much estrogen—either from the body’s own production or from these imposters—throws off the natural hormonal balance.
Estrogen and Hormone Disruption: How xenoestrogens Disrupt Hormone Balance.
Mimicking Real Estrogen
When xenoestrogens enter the body, they bind to estrogen receptors, tricking the body into thinking it has more estrogen than it actually does. This can overwhelm the natural hormonal pathways, leading to imbalances. Because xenoestrogens do not exactly replicate the behavior of natural estrogen, they can disrupt normal cell signaling, causing an overreaction or underreaction in various tissues.
Creating Estrogen Dominance
Estrogen dominance occurs when the body has too much estrogen relative to other hormones, especially progesterone. Xenoestrogens amplify this imbalance by binding to receptors and lingering in body tissues, particularly fat. In women, estrogen dominance may lead to irregular periods, heavy bleeding, fibroids, and mood swings, while men might experience decreased libido, reduced muscle mass, and even the development of breast tissue. This dominance can also disrupt testosterone levels in men AND women, causing fatigue and a lack of motivation.
The Impact on Other Hormones
Estrogen dominance affects a cascade of hormones across the endocrine system, impacting:
Progesterone: In women, the natural balance between estrogen and progesterone is essential for reproductive health and mental well-being. Xenoestrogens throw off this balance, often suppressing progesterone’s effects, leading to symptoms like anxiety, irritability, and sleep disturbances. Progesterone is a calming hormone and is also very protective against more "alpha' estrogen receptors, turning them into more "beta" (calm) estrogen and thus, making them less harsh acting. It is the nasty alpha estrogen receptors that lead to estrogen related cancers/disease. We call estrogen that doesn't have enough progesterone "unopposed" estrogen.
Testosterone: Estrogen dominance can lower testosterone levels in both men and women. In men, this leads to issues with mood, muscle development, and energy. Women may experience lower libido and a general feeling of lethargy. But estrogen dominance can lead to issues with a hormone called SHBG that can actually increase testosterone TOO high and create harsh side effects like hair loss, acne, fertility issues, and insulin resistance.
Thyroid Hormones: High estrogen levels interfere with thyroid function, often reducing the thyroid’s ability to produce adequate hormones, leading to symptoms such as cold sensitivity, weight gain, and slowed metabolism. A slow thyroid also makes it hard to clear out estrogen from the body thus creating a vicious cycle.
Cortisol: Excess estrogen may impact cortisol production and regulation, leading to increased stress response, fatigue, and potential adrenal fatigue.
Effects on the Microbiome
The health of our gut is deeply connected to our hormone levels, especially when it comes to estrogen. Our microbiome, which consists of trillions of microorganisms, plays a significant role in hormone detoxification. The estrobolome, a subset of gut bacteria, helps process and eliminate estrogen. When xenoestrogens enter the system, they can overwhelm this process, leading to the reabsorption of estrogen back into the bloodstream, compounding estrogen dominance.
Gut health imbalances caused by xenoestrogens can lead to:
Poor Digestion: Estrogen dominance has been linked to bloating, constipation, and irregular bowel movements.
Impaired Detoxification: Xenoestrogens interfere with the liver’s ability to process and excrete estrogen, further burdening the body and increasing the risk of estrogen dominance.
Increased Inflammation: Gut imbalances contribute to systemic inflammation, which has been linked to a higher risk of autoimmune disorders and mental health challenges.
Health Issues Caused by Estrogen Dominance and Xenoestrogens
Reproductive Health Problems: In women, excess estrogen can lead to issues like endometriosis, polycystic ovary syndrome (PCOS), and fertility challenges. In men, it may result in decreased sperm count and erectile dysfunction.
Increased Cancer Risk: Estrogen dominance has been associated with a higher risk of hormone-related cancers, including breast, ovarian, and prostate cancer.
Weight Gain and Metabolic Issues: Excess estrogen encourages fat storage, particularly around the hips and thighs, making weight loss more challenging. It also disrupts blood sugar regulation, potentially leading to insulin resistance and metabolic syndrome.
Mood Disorders: Estrogen dominance is associated with mood swings, irritability, and even depression due to its impact on neurotransmitter function.
Thyroid Dysfunction: Elevated estrogen can affect thyroid hormone conversion, leading to hypothyroid symptoms, even if blood tests for thyroid levels appear normal.
Fatigue and Low Energy: Due to its effects on cortisol and thyroid hormone levels, estrogen dominance can lead to chronic fatigue and low energy, making it challenging to stay active and motivated.
Practical Tips to Reduce Xenoestrogen Exposure and Restore Balance
Use Natural Personal Care Products: Many cosmetics, lotions, and soaps contain xenoestrogens like parabens and phthalates. Opt for organic, natural brands whenever possible to limit exposure.
Avoid Plastics: BPA, a common plastic additive, is a well-known xenoestrogen. Use glass or stainless steel containers for food and beverages, and avoid microwaving food in plastic containers.
Eat Organic Produce: Conventionally grown produce is often treated with pesticides that contain xenoestrogens. Choose organic options when possible to reduce your intake of these chemicals.
Support Gut Health: Incorporate foods high in fiber and probiotics to support gut health, which aids in estrogen metabolism and detoxification. Foods like fermented vegetables, high-fiber grains, and leafy greens can be beneficial.
Prioritize Liver Health: The liver plays a crucial role in processing and removing excess estrogen. Support it with foods like leafy greens, cruciferous vegetables, and antioxidant-rich berries.
Exercise Regularly: Physical activity helps maintain a healthy weight, which is essential because xenoestrogens are stored in fat tissue. Exercise also boosts circulation and supports hormone balance.
Make sure you have proper mineral balance and hydration: Minerals and those that hydrate our bodies are what carry out much of the cells function. Not only that but they actually drive many of the glands of our body. Imbalanced minerals are a host for many issues in our hormonal system with both the production, elimination, and use of hormones. See HTMA mineral analysis for more info HERE.
Consider Functional Testing: Tests like the GI-Map, hormone panels, and HTMA (Hair Tissue Mineral Analysis) can help determine if xenoestrogens or estrogen dominance are affecting your health. Functional testing provides insights into what’s actually going on in your body, allowing for more tailored solutions. Check out more info on functional testing here.
Estrogen Dominance, Cellular Health, and Nutrient Absorption
Estrogen dominance doesn’t just affect hormone levels; it can disrupt the health of our cells on a fundamental level. Cells are the body’s foundation, and when they’re disrupted by an overload of estrogen and xenoestrogens, it impacts their ability to carry out essential functions, such as nutrient absorption, energy production, and detoxification.
Disrupted Cell Signaling
Cells rely on clear signaling to perform their tasks and communicate with one another. With estrogen dominance, the excess estrogen binding to cell receptors interferes with normal hormonal messaging. The overload of “false” estrogen signals confuses cells, leading to mixed responses that can hinder cellular growth, repair, and the production of necessary proteins and enzymes. This “signal overload” disrupts normal cell function, making it harder for cells to operate efficiently.
Impaired Nutrient Absorption
Estrogen dominance can impair nutrient absorption in two primary ways:
Altered Digestive Environment: As estrogen dominance influences the gut microbiome, it can reduce the diversity and functionality of beneficial bacteria essential for breaking down food and absorbing nutrients. This can result in malabsorption of key nutrients, including B vitamins, magnesium, zinc, and other minerals vital for hormonal balance and cellular function. These nutrients deficiencies start to even further disrupt hormone production and regulation as time goes on as our glands require these nutrients to function properly.
Inflammation at the Cellular Level: Excess estrogen and xenoestrogens can create inflammation within cells, especially in the gut lining. This inflammation damages the cells responsible for nutrient absorption, causing nutrients to pass through the digestive tract without being adequately absorbed. Histamine is also released with excess estrogens leading to even more chronic stress and inflammation in the body. Over time, chronic inflammation can lead to a leaky gut, where the gut lining becomes permeable and allows partially digested food and toxins into the bloodstream. This further stresses the immune system and can lead to nutrient deficiencies.
Oxidative Stress and Cellular Damage
Excess estrogen, particularly when not properly metabolized, contributes to oxidative stress—an imbalance between free radicals and antioxidants in the body. Oxidative stress damages cell membranes, mitochondria (the powerhouse of the cell), and DNA. Mitochondrial damage, in particular, disrupts energy production, leading to fatigue and low vitality at the cellular level.
Diminished Detoxification Capacity
Cells also need to detoxify themselves from waste products and foreign chemicals like xenoestrogens. However, the liver and cells throughout the body can become overwhelmed when estrogen dominance is present. As a result, toxins that should be eliminated from the body end up lingering in cells, further disrupting cellular function and increasing the risk of long-term health issues, including chronic fatigue, immune dysfunction, and even cellular mutations. Enzymes like Beta-Glucuronidase can become elevated. This enzyme is responsible for attaching to toxins like excess estrogens and pulling them out of the body. When it becomes too elevated through gut dysbiosis and estrogen dominance, the body continues to recirculate estrogen instead of eliminating it. (See former blog post on Beta-Glucuronidase here).
Supporting Cellular Health Amid Estrogen Dominance
Focusing on cellular health through diet, lifestyle, and targeted supplements can help counteract the negative effects of estrogen dominance on cells:
Antioxidants: Including antioxidant-rich foods (berries, green tea, leafy greens) helps combat oxidative stress and supports cell health.
B Vitamins and Magnesium: These are crucial for energy production at the cellular level and are often depleted in estrogen-dominant states. I don't recommend blindly supplementing however. At the point of nutrient imbalances, single nutrient supplementation can further drive imbalances. Many of the functional tests can reveal what is needed for the hormones, nutrients, and digestion to come back into balance.
Fiber and Liver-Supportive Foods: These support the liver’s detoxification processes, helping the body to clear out excess estrogen and prevent it from re-entering circulation.
When cells function optimally, our bodies are better equipped to absorb nutrients, produce energy, and protect against the adverse effects of environmental estrogens. Supporting cellular health is an essential piece of the puzzle in overcoming estrogen dominance and restoring overall wellness.
Empowering Yourself Through Awareness and Action
Estrogen dominance and xenoestrogen exposure are stealthy disruptors of hormonal balance that can impact nearly every area of your health, from energy and mood to weight and reproductive function. Awareness is the first step in combatting these effects, but taking proactive measures to reduce xenoestrogen exposure and support hormone balance is crucial for long-term health.
In your journey to better health, it’s helpful to remember that small, consistent changes often yield the best results. Whether it’s switching to glass containers, choosing natural skincare, or incorporating liver-supportive foods into your diet, each action contributes to a cleaner, healthier environment for your hormones to function optimally.
