Estrogen, a hormone often vilified and misunderstood, has been the subject of much debate and controversy. While some view it as the root cause of various health issues, others recognize its vital role in the body's well-being. To shed light on this complex topic, we sat down with Dr. Tara Scott, a renowned hormone expert and OB-GYN who practices functional medicine.

As Dr. Scott eloquently puts it, "The biggest issue with women in estrogen dominance is not the actual level of estrogen, it is not the actual level of progesterone, it's the ratio, and most of the time, it's how you metabolize it." This statement encapsulates the core of the estrogen debate – it's not about the hormone itself, but rather the delicate balance and proper metabolism that determines its impact on our health.

Understanding Estrogen: The Three Sisters

Before exploring the complexities of estrogen's role, it's essential to understand the different types of estrogens present in our bodies. Dr. Scott refers to them as "the three sisters":

1. Estradiol: "She's the oldest. She's the popular one, athletic and popular. Estradiol is the strongest, most potent." This is the primary estrogen the ovaries produce during a woman's reproductive years and plays a crucial role in the menstrual cycle and ovulation.
2. Estrone: "Estrone, that's the one that gets the bad wrap, but it really depends on how much estrone you have in relationship to both progesterone and estradiol." Estrone is produced in smaller amounts by the ovaries and can also be formed through peripheral conversion from other hormones, like androstenedione. It has a propensity to promote growth in breast and uterine tissues.
3. Estriol: "The weak little estrogen. I think of that as a youngest sister and really not produced in quantity unless you're pregnant." Estriol is primarily produced by the placenta during pregnancy and is considered the weakest of the three estrogens.

The Benefits of Estrogen

Far from being the root of all evil, estrogen plays a vital role in various aspects of our health. As Dr. Scott explains, "There's a fair amount of data, although we're not allowed to say it will prevent heart disease…. if you even look at the incidence of heart disease, it's much higher in men than women up until menopause."

Estrogen is also instrumental in maintaining bone health and protecting against osteoporosis. Dr. Scott points out that "the death rate two years after a hip fracture is higher than ten years after breast cancer diagnosis, but everybody fears cancer." Estrogen's protective effects extend beyond the skeletal system and play a crucial role in brain health. An observational trial involving 400,000 women over the age of 65 found a staggering 60% reduction in Alzheimer's disease in those with adequate estrogen levels. Let’s find this study and link here

The Estrogen Roller Coaster let’s pick one analogy here and stick with it

While estrogen is essential for our well-being, imbalances can lead to a range of symptoms. Dr. Scott likens the fluctuations in estrogen levels to a roller coaster, noting, "There's one specific ride now that you made me think about that has a crazy high hill and then it goes down and has the lower hills. That makes me think of estrogen."

During a woman's reproductive years, estrogen levels fluctuate throughout the menstrual cycle, rising and falling in a controlled manner. However, as women approach perimenopause, this delicate balance can be disrupted, leading to a condition known as estrogen dominance.

"You have old eggs. What does that mean? That means they are hard of hearing," Dr. Scott explains. "That means that lifeguard in that chair is going to start picking up his megaphone because he might say, 'Your turn, your turn,' and then all the eggs just sit there because nobody steps up because they can't hear because they're old." This can result in an imbalance between estrogen and progesterone, causing symptoms such as heavy bleeding, fibrocystic breasts, endometriosis, fibroids, migraines, and mood changes.

The Root Cause: Estrogen Metabolism

While many focus on estrogen levels alone, Dr. Scott emphasizes the importance of understanding estrogen metabolism. She likens estrogen to credit card charges, while progesterone is the payment that clears the balance. "It'd be like estrogen's the amount that you charge on your credit card and progesterone's what you pay off. If you charge on your credit card $10,000 every month but you pay it off, there's no issue. If I charge $1,000 and I don't pay it off, there's an issue there."

Estrogen metabolism involves a complex detoxification process that occurs primarily in the liver. Dr. Scott breaks it down into three phases:

1. Phase 1: "Estrogen's floating around, and there's a chemical reaction that changes it, that makes it what's called intermediate metabolite." This initial phase involves estrogen metabolism into intermediate metabolites, primarily by cytochrome P450 enzymes in the liver.
2. Phase 2: "It's like estrogen gets tied up in a package and then goes down the shoot into the gut or into the liver." In this phase, the estrogen metabolites undergo further metabolism and "packaging," often through methylation, to make them more polar for excretion. 
3. Phase 3 (Gut Phase): "It's really complicated, obviously. This is something that happens in the cell all the time. The gut is part of it, like phase three estrogen detoxification." The packaged estrogen metabolites get excreted through the bile into the gut, where gut bacteria can deconjugate and reabsorb some of them back into circulation.

Imbalances in any of these phases can lead to estrogen dominance, even if the overall estrogen levels appear normal. Dr. Scott emphasizes the importance of testing, stating, "The ideal test, if everything was free, would be the cycle map because then you're getting 11 different readings."

Environmental and Lifestyle Factors

While genetics play a role in estrogen metabolism, environmental and lifestyle factors can also significantly impact this process. Dr. Scott highlights the influence of stress, gut health, and exposure to endocrine-disrupting chemicals found in plastics and other products.

"You may have a perfect diet and you may exercise, you may have no stress, but we're exposed to all these chemicals that are endocrine disruptors that can mimic estrogen. There are certain chemicals that can prevent the enzymes that get rid of estrogen, that can make them slower," she explains.

Addressing these factors holistically, including stress management, a nutrient-dense diet, and minimizing exposure to harmful chemicals, can support optimal estrogen metabolism and overall hormonal balance.

Testing and Individualized Approach

One key takeaway from Dr. Scott's expertise is the importance of testing and an individualized approach. She emphasizes, "I definitely think that's a plug for whatever type of testing you have available for yourself." Whether it's blood testing, saliva testing, or the comprehensive include link DUTCH test, understanding an individual's unique hormonal profile is crucial for effective treatment.

"It's not like we're trying to have this secret hormone club that only we have to see every patient, you know what I mean?" Dr. Scott reassures.

Practical Strategies for Hormonal Balance

While addressing estrogen imbalances may require personalized interventions, Dr. Scott offers some practical strategies that can benefit everyone:

1. Prioritize sleep and stress management: "I don't say stress reduction anymore, but stress management, and just eating clean and just moving your body like those pillars. Those are really important for estrogen metabolism."
2. Mindful consumption: "I think we forget how much estrogen is affected by stress or is affected by sugar or alcohol."
3. Environmental considerations: "We talked about plastics, and environments, and organic food, and grass-fed beef and all those things can get you pretty far before you even have to take a supplement or a hormone."
