The signs and symptoms of estrogen dominance are physical warnings that we could very easily attribute to day to day factors like stress, a poor diet, not getting enough sleep or exercise.

While it may be easy to ignore these symptoms a lot of the time, deeper investigation into your hormones can really explain a lot.

Hormones play a huge role in our lives. No matter how much we know about hormones or work to control our hormonal health, fluctuations may have a significant impact on our overall well-being in our day to day lives.

When you are experiencing hormonal imbalances, you may start to notice that you're tired all of the time, but dismiss it as increased demands from your work and home life. You may notice your period is irregular and think “it’s just stress”.

What you may not realize is that you could be experiencing a condition called "Estrogen Dominance". While it may sound scary, symptoms of high estrogen levels (estrogen dominance) are extremely common in women over the age of 35 and may be the root of your bothersome symptoms.

In this article, LetsGetChecked discuss what estrogen dominance is, the signs and symptoms of estrogen dominance and how to treat estrogen dominance for better hormonal health.

What Is Estrogen Dominance?


Estrogen dominance occurs when the volume of estrogen supersedes the volume of progesterone circulating in the bloodstream. It is also described as the disruption or the imbalance between estrogen and progesterone.

This condition is most common in women over the age of thirty five years old and the symptoms of estrogen dominance can vary from moderate to severe.

Dr. John R. Lee pioneered the term "estrogen dominance" to mean having deficient, normal or excessive estrogen without enough progesterone to balance its effects. For some women, this is a condition they have from the time they begin their menstrual cycle for others, it is a condition that begins with perimenopause.


The Estrogen and Progesterone Balancing Act


Estrogen and progesterone are the two most prominent hormones in females.

Estrogen and progesterone work in conjunction with one another to carry out a number of primary functions in women.

Estrogen

Estrogen is known as the “female” sex hormone. Estrogen helps regulate the menstrual cycle, controlling the growth of the uterine lining during the first part of the cycle. It is primarily produced in the ovaries, however, it is also produced by fat cells and the adrenal glands.

In another article, we spoke about the effects of estrogen on weight, particularly in men. Men who have higher levels of estrogen in the body than testosterone have a far higher likelihood of being overweight.

Watch this video with Dr. Dominic Rowley to learn more about estrogen:

Progesterone

Progesterone is another “female” sex hormone. It is released by the corpus luteum (the shell that contains the egg) in the ovary when the egg breaks free and starts its journey from the fallopian tube to the womb.

The goal of the egg that has just been released from the fallopian tube makes its way from the fallopian tube to the womb to be fertilized by a healthy sperm.

Progesterone prepares the body for pregnancy in the event that the released egg is fertilised. If the egg is not fertilised, the corpus luteum eventually fully breaks down, with the the production of progesterone decreasing and a new menstrual cycle beginning.

Watch this video with Dr. Dominic Rowley to learn more about progesterone:

Overall, the functions of estrogen and progesterone can either be complementary or work in opposition to one another to produce a range of everyday symptoms and side effects.

Your levels of estrogen and progesterone fluctuate with the beginning of your menstrual cycle.

When you start your period, your body is producing some estrogen and almost no progesterone. Just before ovulation, your estrogen levels increase dramatically stimulating the release of the egg from the ovaries.

This graph illustrates the rise and fall of hormones during your cycle, indicating when you should take a female hormone test.

After the egg is released, your body begins to produce progesterone to prepare the lining of your uterus for implantation of a fertilized egg, or pregnancy. If you do not become pregnant, progesterone levels drop dramatically signaling the body to shed the uterine lining, which marks the start your period and the whole cycle all over again.

Some of the most common symptoms of PMS include negative mood changes, fatigue, weight gain, sore or heavy-feeling breasts, spotty skin, an increased appeitie and a lowered sex drive.

The signs and symptoms of estrogen dominance often mimic the symptoms of PMS, however if you are experiencing estrogen dominance, these symptoms may occur over an extended period of time, indicating that this is more than a fluctuation in your normal hormonal levels.

Before we go through the signs and symptoms of estrogen dominance, let’s take a look at some of the possible causes of estrogen dominance.


What Are The Causes Of Estrogen Dominance?


There are three main causes of high estrogen levels in women including the environment, nutrition, and age.

Environment

Xenoestrogens , or synthetic estrogen compounds are found in everything from styrofoam containers to detergents and lotions.

Pesticide, plastic, and car exhaust fumes all contribute to high levels of xenoestrogens in our everyday environment. While it is not possible to avoid all synthetic estrogen, there are ways to counter-balance estrogen levels by being proactive in other areas of your life.

For instance, the hormone cortisol is directly linked to the fight or flight hormone we all experience when we are stressed. Your body will actually use progesterone to produce cortisol, stressing your adrenal glands to produce more progesterone for normal hormonal balance. In many women, this balance cannot be maintained, progesterone levels will drop, and estrogen dominance will emerge.

Nutrition

We all know a well-balanced diet is important to looking and feeling great, but your diet can actually affect the levels of estrogen in your body.

While soy products are key replacement for protein in many vegetarian diets, the consumption of soy has been linked to estrogen dominance.

Soy contains phytoestrogens that mimic the role estrogen plays in your body. When you eat a diet rich in soy products, your body’s estrogen receptors are activated.

If your body continues to produce the same amount of estrogen it normally needs, you may experience estrogen dominance.

It is not enough to simply stop drinking soy milk. Most women are deficient in the twin minerals magnesium and calcium. While calcium is linked to bone, hair, and tooth health, it cannot be absorbed without sufficient magnesium in the body. However, your body also uses magnesium to metabolize extra estrogen and get rid of it through the liver. If you are already deficient in magnesium (which most women are), your body will burn through your magnesium stores trying to bring back your hormonal balance and you can end up with kidney stones, blood clots, or gallstones.

Cervical-cancer---new

Body fat and estrogen dominance often go hand in hand. Think of the fat on your body like an organ. Like any organ, it produces hormones and provides an important function.

Fat cells produce estrogen. This is why women have a naturally higher body fat percentage than men, as a backup hormone source for a developing baby.

Remember those xenoestrogens? Turns out they’re fat soluble, accumulate over time, and are typically stored in your fat cells.

This means the fat cells that were producing estrogen are now overloaded with synthetic estrogens as well resulting in a never-ending estrogen assault on your body. Reducing your body fat percentage to below 28% can have a profound effect on any signs and symptoms of estrogen dominance.

Age

After the age of 35, many women enter the phase of reproduction called “perimenopause”.

From the age of 35 to 50, there is a 35% decrease in the amount of estrogen you produce, but a much bigger drop in progesterone of 75% as your cycles becomes increasingly anovulatory (you don’t ovulate).

In this instance, estrogen levels remain high but your body can no longer combat them with appropriate amounts of progesterone. As a result your estrogen levels are much higher than your progesterone levels, causing estrogen dominance.

Not only does this condition cause irregular periods, it can also contribute to a whole host of other symptoms.


What Are The Signs And Symptoms Of Estrogen Dominance?


Symptoms of estrogen dominance vary from person to person and depends largely on your level of hormonal imbalance. Common symptoms of estrogen dominance include:

estrogen-the-signs-and-symptoms-of-estrogen-dominance-illustration-1

Remember, while these are all symptoms of estrogen dominance, they can also signal other health problems. The best (and only) way to know if too much estrogen is to blame for your symptoms is to have your hormone levels checked by your physician. This is done with a simple blood or saliva test designed to check all hormone levels and the ratios of estrogen and progesterone in your body.

Women who have experienced normal menstrual cycles their entire lives, are at risk for estrogen dominance when their ovaries stop ovulating regularly. In fact, it was once believed that these symptoms were indicative of ovaries that were not functioning well and the solution was to Prescribe estrogen medication in an attempt to stimulate ovary function.

However, Endocrinologist Dr. Jerilynn Prior found that women (between the ages of 35 and 50) experiencing perimenopausal symptoms like hot flashes and heavy periods were actually suffering from high estrogen levels, not low ones. Estrogen levels in perimenopausal women are generally higher than those in younger women meaning the ovaries are working overtime during ahead of the end of menstruation and the beginning of the menstrual cycle.

In sum: The signs and symptoms of estrogen dominance that you need to look out for include:

  • Decreased sex drive
  • Increased PMS
  • Irregular periods
  • Depression
  • Mood swings
  • Headaches
  • Bloating
  • Hot flashes
  • Tenderness in the breasts
  • Weight gain
  • Fatigue
  • Difficulty concentrating
  • Insomnia

How is Estrogen Dominance Diagnosed?


If you suspect your symptoms are linked to estrogen dominance, the first step is to record your symptoms, at what point in your menstrual cycle they appear, and how long they last. Do NOT change your diet, begin an exercise routine, or begin taking progesterone cream before an appointment with a medical professional.

Next you have one of two options:

Option 1
Discuss your symptoms with your doctor. At your appointment, give your doctor all of your information including any medications you are taking and ask your healthcare provider to check your hormone levels.

Option 2
Order an at home hormonal imbalance blood test to measure your progesterone and estrogen levels. At LetsGetChecked we offer easy to use female fertility test kits. When you send your kit back to the lab, one of our trained nurses will call you to discuss your results with you to make sure you fully understand what the results mean.

Testing for estrogen dominance is a bit tricky however. Because your hormone levels vary throughout your menstrual cycle, it is very important that the blood test is taken at the right time in your cycle to give the most accurate picture of your hormone levels.

Progesterone tests need to be taken on day 21 of your menstrual cycle to measure the amount of progesterone in your system after ovulation, and estrogen blood tests need to be taken on day 3 of your menstrual cycle (the third day of blood flow during your period) to get the most accurate results.


How Does Estrogen Dominance Affect Pregnancy?


how-does-estrogen-dominance-affect-pregnancy-1

Hormonal imbalances including estrogen dominance are often responsible for fertility issues couples may face when trying to get pregnant.

Whether you between the ages of 30 and 50, or are experiencing a secondary syndrome that affects ovulation (such as polycystic ovarian syndrome or endometriosis) chances are you are not experiencing ovulation despite having a normal menstrual cycle. These anovulatory cycles can cause estrogen dominance.

Usually, an egg is released from the ovary and travels to the uterus to await fusion with a sperm. After the egg is released, its empty follicle becomes a factory for progesterone production until the egg is either fertilized and implants in your uterus or your period begins. If you do not ovulate, there is no empty follicle for progesterone production. No progesterone production causes estrogen dominance.

Having adequate levels of progesterone are essential to becoming pregnant and staying pregnant until the placenta takes over progesterone production. If you are not estrogen dominant your progesterone levels will remain high after implantation, and your body will not send the signal to begin your period. If you are experiencing estrogen dominance, progesterone levels will not be high enough to maintain a pregnancy, even if implantation has occurred and you will start your period. Likewise, if progesterone levels are high enough to become pregnant then become unbalanced within the first weeks, there is an increased risk of miscarriage.


What Are The Serious Negative Side Effects of Estrogen Dominance?

A hormone imbalance doesn’t just affect how you feel, it can affect how your body operates. While the initial symptoms listed above of too much estrogen can be annoying, allowing estrogen levels to build up to unhealthy levels can cause some real health problems including:

These conditions are serious, however, the good news is that their development is slow so if you are vigilant and take action when you notice the early signs of estrogen dominance then you can reduce the chances of these conditions developing.

In sum: Some of the most common serious side effects of include:

  • A complete lack of ovulation (and periods)
  • Infertility
  • Endometriosis
  • Heavy bleeding
  • Fibroids
  • Uterine cancer
  • Low-grade dementia
  • Breast cancer
  • Heart disease
  • Stroke

How Do I Know If I Have Estrogen Dominance?


Answering the question “How do I know if I have estrogen dominance?” isn’t always easy, because as mentioned, the signs and symptoms of estrogen dominance are not always obvious and they can be attributed to different things that affect our everyday lives.

The best thing you can do if notice that you are experiencing negative symptoms is to start taking note of when they started and exactly what they feel like. This will make it easier for you in the long run when you want to pinpoint exactly when this started, and the severity of each symptom.

If you are feeling very unwell, you need to go straight to your physician’s office for a check up.

In instances where the symptoms are not too severe but you want to have a better understanding of what might be going on, you have the option to take fertility tests from the comfort of your home.

The LetsGetChecked tests are convenient options that make it possible for you to better know your health. Whatever the reason, you may not want to visit the physician’s office, have a face to face consultation or take time off work.

For a lot of people, time is the biggest factor that prevents them from taking a prevention stance when it comes to their health.

With LetsGetChecked, there is no excuse and no barriers to putting off getting tested.

While taking a progesterone supplement may be called for in order to correct estrogen dominance, it is not always necessary. Instead, there are a few natural ways to decrease estrogen dominance without a prescription.


Are There Natural Methods To Decrease Estrogen Dominance?


Diet

Eat lots of organic fruit and vegetables with adequate amounts of protein that is not soy based or grown with artificial growth hormones. Dark leafy green vegetables are high in magnesium and B vitamins that are essential for the metabolism of estrogen in the body.

Eat More Fiber

This is so important, it warrants special mention. Estrogen is excreted through bowel movements. If stool takes a long time to wind its way through your bowel, estrogen will actually be reabsorbed by your body in the process. The best way to avoid this is to eat a diet high in insoluble fiber.

Lose Excess Body Fat

Do everything you can to reduce your body fat percentage below 28%. By losing excess weight through a proper diet and exercise, you will also lose the body’s ability to store and produce excessive amounts of estrogen.

Decrease Stress in Your Life

Remember, your body uses progesterone to create cortisol. The more of your life you spend in “fight or flight” mode, the more progesterone your body will use. Learn to say, “NO”. Invest time in your hobbies, interests, and experiences that will allow you to reduce stressors and increase your sense of well-being.

Ditch the Caffeine

Studies have shown that women who consume at least 500 milligrams of caffeine (5 cups of coffee) a day have nearly 70% more estrogen than those who consume less than 100 milligrams of caffeine a day. Caffeine intake is linked with these higher levels of estrogen regardless of how old you are, what you weigh, and whether you smoke or drink alcohol.

Whether you know you are experiencing estrogen dominance or merely suspect you are, remember that this is a condition that largely be mitigated by a few simple changes in lifestyle. Estrogen dominance is not a life-sentence, but merely a bump in the road on your way to a long, healthy reproductive life.
