What Causes High Estrogen Levels?

Your estrogen levels may be elevated due to estrogen production from medications or difficulty breaking down estrogen in your body. Here are some causes of high estrogen levels:

  • Polycystic Ovary Syndrome (PCOS): High estrogen in women may be caused by Polycystic Ovary Syndrome (PCOS), a hormonal disorder affecting the female reproductive system that leads to irregular menstruation and fertility problems 5 – 15% of women of reproductive age have PCOD, making it a prevalent factor leading to estrogen level increase.
  • Underactive thyroid: It is one of the common causes of high estrogen levels in women. When the thyroid gland does not produce enough hormones, it causes hormonal imbalances, which can cause weight gain, fatigue, and menstrual irregularities.
  • Certain medications: Some medications, like hormone replacement therapy and birth control pills, can increase estrogen levels in women. This can have various effects on the body, such as changes in menstrual cycles, breast tenderness, and mood swings.
  • Liver disease: Your liver breaks down estrogen and removes it from your body, so if your liver is not working properly, it can bring too much estrogen. Proper liver function is essential for maintaining hormonal balance in women.
  • Environmental Toxins: Some chemicals in the environment, such as xenoestrogens, can mimic the effects of estrogen in the body. Xenoestrogens are found in some plastics, pesticides, and herbicides.


Signs and Symptoms of High Estrogen

  • Uterine fibroids: Uterine fibroids are growths in the uterus that are caused by high levels of estrogen in women. Estrogen dominance can lead to the development of these fibroids due to hormonal imbalances.
  • Endometriosis: Endometriosis is a condition where tissue similar to the uterus grows outside the womb. They are often linked to high levels of estrogen in women.
  • Weight gain: Women can gain weight due to regulating metabolism and fat distribution in the body. Various factors like diet and lifestyle can contribute to this hormonal imbalance.
