Estrogen Dominance and Xenoestrogens

Updated: Feb 11, 2021

As with all things in life, balance is key. Hormones are no exception to this rule. Balanced hormones are not only vital for reproduction, they also play a role in nearly all major organ systems, including heart health, bone health and brain health. Too much of a hormone, however, may negatively impact our physiology.

Estrogen, a major hormone in women, may cause significant symptoms if it is out of balance. Excess estrogen, or estrogen dominance, can lead to the development of various symptoms, including:


Mood swings

Weight gain

Hair loss

Headaches

Anxiety and panic attacks

Cervical dysplasia, or development of abnormal cells of the cervix

Heavier cycles

Water retention

Depression

Risk of uterine or breast cancer

Swollen breasts

Risk of hypothyroidism


So how can we develop too much estrogen? One of the major causes consists of environmental estrogens, such as xenoestrogens. Xenoestrogens imitate estrogen and are toxic to our body. These toxic chemicals, found in everyday items, can interfere with our endocrine process, altering the normal function of our hormones.


Common sources of xenoestrogens include pesticides and herbicides, animal meats that are fed synthetic hormones, makeup and skincare products that contain parabens, sunscreen products that contain 4-methylbenzylidene camphor (4-MBC) and plastic.


We do encourage all patients to thoroughly examine and assess all labels and ingredients regularly. Consider reducing or avoiding products with these toxic chemicals and be sure to monitor your hormones regularly to achieve hormone balance!
