Menopause & hormones

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.
