Side Effects of Estrogen Replacement Therapy


Estrogen replacement therapy  alleviates symptoms such as headaches.Estrogen replacement therapy (ERT) is the introduction of external estrogen into a woman’s body and is normally prescribed to women who have had their uterus surgically removed. However, it is also beneficial for women who are experiencing estrogen deficiency due to menopausal fluctuations, and it alleviates symptoms such as hot flashes, headaches, and mood swings. Estrogen is available as pills, vaginal creams, vaginal ring inserts, implants, shots and patches that are applied to the skin.

Dangers of Estrogen Replacement Therapy

A 2002 landmark study by the Women’s Health Initiative (WHI) caused controversy by demonstrating a link between estrogen replacement therapy and breast cancer. Because the majority of estrogen used in estrogen replacement therapy is not generated by a woman’s own body, there are certain dangers and reactions that can occur. In addition to aggravating symptoms that women with hormonal dysfunction may already be suffering, side effects of it may also include more serious conditions. An excess of estrogen caused by synthetic hormones has been linked to the following conditions:

  • Increased risk of cancer. If higher doses of estrogen replacement therapy are used for long periods of time, it has been shown to raise the risk of cancer of the uterus, ovaries, and breasts.
  • Gallbladder disease. It’s believed that women who use estrogens after menopause are at greater risk of developing gallbladder disease that requires surgery.
  • Abnormal blood clottingAbnormal blood clotting. Estrogen replacement therapy could prompt blood clotting which can cause a stroke, heart attack, or pulmonary embolus.
  • Excess calcium in the blood. Synthetic estrogen may cause hypercalcemia in women suffering from bone or breast cancer.
  • Increase in incontinence. Incontinence and uterine may become prolapsed.
