Menopause and Hormones

From the FDA web site: www.fda.gov

What is menopause?

Menopause is a normal change in a woman’s life when her period stops.  That’s why some people call menopause “the change of life” or “the change.”  During menopause a woman’s body slowly produces less of the hormones estrogen and progesterone.  This often happens between the ages of 45 and 55 years old.  A woman has reached menopause when she has not had a period for 12 months in a row.

What is hormone therapy for menopause?

Hormone therapy for menopause has also been called hormone replacement therapy (HRT).  Lower hormone levels in menopause may lead to hot flashes, vaginal dryness and thin bones. To help with these problems, women are often given estrogen or estrogen with progestin (another hormone).  Like all medicines, hormone therapy has risks and benefits.  Talk to your doctor, nurse, or pharmacist about hormones.  If you decide to use hormones, use them at the lowest dose that helps.  Also use them for the shortest time that you need them. (For example, check every 3-6 months to see if you still need them).

What are the symptoms of menopause?

Every woman’s period will stop at menopause.  Some women may not have any other symptoms at all. As you near menopause, you may have:

  • Changes in your period-time between periods or flow may be different.
  • Hot flashes (“hot flushes”)-getting warm in the face, neck and chest.
  • Night sweats and sleeping problems that may lead to feeling tired, stressed or tense.
  • Vaginal changes-the vagina may become dry and thin, and sex may be painful.
  • Thinning of your bones, which may lead to loss of height and bone breaks (osteoporosis).

What are the benefits from using hormones for menopause?

  • Hormone therapy is the most effective FDA approved medicine for relief of hot flashes, night sweats or vaginal dryness.
  • Hormones may reduce your chances of getting thin, weak bones (osteoporosis) which break easily.

What are the risks of using hormones?

Hormone therapy increases women’s chances of getting blood clots, heart attacks, strokes, breast cancer, and gall bladder disease.  For a woman with a uterus, estrogen increases her chance of getting endometrial cancer (cancer of the uterine lining).  (Adding progestin lowers the risk of endometrial cancer).
