Hormone replacement therapy (HRT) – WebMD

If youre looking for relief from menopause symptoms, knowing the pros and cons of hormone replacement therapy (HRT) can help you decide whether its right for you.

HRT (also known as hormone therapy, menopausal hormone therapy, and estrogen replacement therapy) uses female hormones -- estrogen and progesterone -- to treat common symptoms of menopause and aging. Doctors can prescribe it during or after menopause.

After your period stops, your hormone levels fall, causing uncomfortable symptoms like hot flashes and vaginal dryness, and sometimes conditions like osteoporosis. HRT replaces hormones your body no longer makes. Its the most effective treatment for menopause symptoms.

You might think of pregnancy when you think of estrogen. In women of child-bearing age, it gets the uterus ready to receive a fertilized egg. It has other roles, too -- it controls how your body uses calcium, which strengthens bones, and raises good cholesterol in the blood.

If you still have your uterus, taking estrogen without progesterone raises your risk for cancer of the endometrium, the lining of the uterus. Since the cells from the endometrium arent leaving your body during your period any more, they may build up in your uterus and lead to cancer. Progesterone lowers that risk by thinning the lining.

Once you know the hormones that make up HRT, think about which type of HRT you should get:

Estrogen Therapy: Doctors generally suggest a low dose of estrogen for women who have had a hysterectomy, the surgery to remove the uterus. Estrogen comes in different forms. The daily pill and patch are the most popular, but the hormone also is available in a vaginal ring, gel, or spray.

Estrogen/Progesterone/Progestin Hormone Therapy: This is often called combination therapy, since it combines doses of estrogen and progestin, the synthetic form of progesterone. Its meant for women who still have their uterus.

The biggest debate about HRT is whether its risks outweigh its benefits.
