What is Estrogen Dominance?

Balancing out your hormones, if you are a woman, can be tricky business. Yet, when your hormones are off, it can affect you physically, mentally and emotionally in ways that are inexplicable.

The one thing we are hearing more about, especially among women in the United States and more developed countries is estrogen dominance. What is estrogen dominance – it is when the body doesn’t have enough opposing progesterone to lower estrogen levels during the second half of the menstrual cycle. And why would it be a bigger problem in developed countries? It is thought it is due to what is called xenoestrogens, manmade chemicals that mimic estrogen that we consume from our environment – which means that we aren’t necessarily getting enough progesterone but just way too much estrogen.

These hormones can be in our water and food and possibly the usage of birth control pills.

Pesticides are perhaps the biggest source of xenoestrogens. Most bioaccumulate, meaning they are stored in fat cells of fish, poultry and other food sources in increasing concentration until they reach the top of the food chain — where you and I consume them! They are highly estrogenic, and some experts estimate that the average American ingests over a pound of pesticides a year.

A second major source of xenoestrogens is the many growth hormones given to livestock and poultry, most of which contain fat-soluble estrogens. When we consume those animals or their milk, we ingest that estrogen. Organochlorides like dioxin (a by-product of chlorine when it is burned or processed), PCB’s, PVC’s, and some plasticizers are just a few of the many manmade chemicals that act like estrogen in our bodies. Many others have the effect of interrupting our normal endocrine function, hence the term “endocrine disruptors.”

So what are the symptoms of having too much estrogen? Anxiety, breast tenderness, cyclical headaches or migraines, irregular bleeding, water retention, weight gain and more. (Note that a number of these symptoms are also indicative of the exact opposite condition — a deficiency of estrogen — another example of why the concept of estrogen dominance is too simplistic.)

If estrogen levels stay unopposed, women may develop infertility, endometriosis, amenorrhea (skipped periods), hypermenorrhea (heavy bleeding), fibroids, uterine cancer, heart disease and stroke, and decreased cognitive ability, among other conditions.

How can we help ourselves with estrogen dominance? One can start with putting more fiber in our diet.  A low-fiber diet causes estrogen levels to be higher, while a diet high in fiber results in decreased estrogen levels in the bloodstream. Why? Excess estrogen is excreted in the bowel. When stool remains in the bowel for a longer time, the estrogen is reabsorbed. Studies have shown that women on a vegetarian/high-fiber diet have lower levels of circulating estrogen. Lower levels of estrogen mean less estrogen stimulation of breast tissue, for example, which reduces the risk of breast cancer.

We can also help strengthen our liver. The liver is a filter of sorts. It detoxifies our body, protecting us from the harmful effects of chemicals, elements in food, environmental toxins, and even natural products of our metabolism, including excess estrogen. Anything that impairs liver function or ties up the detoxifying function will result in excess estrogen levels, whether it has a physical basis, as in liver disease, or an external cause, as with exposure to environmental toxins, drugs, or dietary substances.

Use dietary supplements. Lecithin (a phospholipid) and the sulfur-containing L-taurine and L-methionine amino acids are compounds that will promote bile circulation, which enhances estrogen’s excretion out of the body. These lipotropic formulas support the liver metabolism of estrogen. A typical formula might provide the following, sometimes in a base of liver-stimulating herbs like milk thistle, black radish, beet, or dandelion, for twice-daily consumption: choline (a concentrated form of lecithin), 500 milligrams; inositol, 250 milligrams; taurine, 250 milligrams; methionine, 250 milligrams.

And last, eat soy foods like bean curd or tofu. They contain phytoestrogens, including diadzin and genistein. They act as estrogen blockers at the tissue level, blocking receptors that could promote cancer.
