Menopause is the permanent end of a woman's menstrual periods. Menopause can occur naturally or be caused by surgery, chemotherapy, or radiation. Many women use complementary and alternative medicine (CAM) for menopausal symptoms.
This fact sheet is based on findings from a 2005 National Institutes of Health (NIH) State-of-the-Science conference on the management of menopause-related symptoms. To find out more about topics and resources mentioned in this fact sheet, see "For More Information."
A woman is said to have completed natural menopause when she has not had a period for 12 consecutive months. For American women, this typically happens at around age 51 or 52. Menopause occurs immediately if the uterus or both ovaries are surgically removed, or if the ovaries are damaged in cancer treatment with radiation therapy or certain drugs.
Common Symptoms During the Menopausal Transition
Some symptoms that women experience are related to menopause and decreased activity of the ovaries. Others may be related to aging in general.
Scientific evidence of a link to menopause is strongest for the following symptoms:
It is not certain whether the following symptoms are due to menopause, other factors that can come with aging, or a combination of menopause and these factors:
The expert panel assembled for the NIH State-of-the-Science conference noted that menopause is a normal part of women's aging and advised that menopause should not be "medicalized" (or viewed as a disease).
Hormone Replacement for Menopausal Symptoms
For decades, hormone replacement therapy (HRT)-more recently known as menopausal hormone therapy (MHT)-was conventional medicine's main treatment for menopausal symptoms. In 2002, findings from a large study called the Women's Health Initiative raised serious concerns about the long-term safety of MHT. These concerns are one reason that many women are turning to CAM therapies.
What the Science Says About CAM Therapies for Menopausal Symptoms
The NIH State-of-the-Science conference panel discussed the evidence on several CAM therapies:
Very little well-designed research has been done on CAM therapies for menopausal symptoms. A small number of studies have been published, but they have had limitations (such as the way the research was done or treatment periods that may not have been long enough). As a result, the findings from these studies are not strong enough for scientists to draw any conclusions. Also, many studies of botanicals have not used a standardized product (i.e., one that is chemically consistent). The National Center for Complementary and Alternative Medicine (NCCAM) is sponsoring a number of studies on botanicals using products that are both well characterized (i.e., their ingredients have been carefully studied) and well standardized and on other CAM therapies that have shown possible promise for reducing menopausal symptoms.
Because CAM products used for menopausal symptoms can have side effects and can interact with other botanicals or supplements or with drugs, research in this area is addressing safety as well as efficacy. Some findings from this research are highlighted below.
Some botanical products, such as soy and red clover, contain estrogen-like compounds called phytoestrogens. Plants rich in phytoestrogens may help relieve some symptoms of menopause. However, it is uncertain whether this relief comes from phytoestrogens or from other compounds in the plant. Much remains to be learned about these plant products, including exactly how they work in the human body. Doctors caution that certain women need to be particularly careful about using phytoestrogens, especially:
DHEA is a naturally occurring substance that is changed in the body to the hormones estrogen and testosterone. It is also manufactured and sold as a dietary supplement. A few small studies have suggested that DHEA might possibly have some benefit for hot flashes and decreased sexual arousal, although small randomized controlled trials have shown no benefit. Because levels of natural DHEA in the body decline with age, some people believe that taking a DHEA supplement can help treat or prevent conditions related to aging; however, there is no good scientific evidence to support this notion.
Concerns have been raised about whether DHEA is safe and effective. Its long-term effects, risks, and benefits have not been well studied, and scientists are not certain whether it might increase the risk for breast or prostate cancer. Before using DHEA for any purpose, people should talk to their health care provider about potential benefits and risks.
If You Are Considering CAM for Menopausal Symptoms
Although there is very little scientific evidence to support the effectiveness of CAM therapies for menopausal symptoms, it is possible that some CAM therapies may provide some relief to women during the menopausal transition. Here are two important points to keep in mind if you are considering these therapies:
Women who are looking for alternatives to MHT should be aware that CAM therapies are not their only option. Certain lifestyle changes can contribute to healthy aging, including during the menopausal transition. For example, quitting smoking, eating a healthy diet, and exercising regularly have been shown to reduce the risks of heart disease and osteoporosis. The NIH State-of-the-Science conference report (see "Selected References") discusses several commonly used non-CAM interventions for relief of menopause-related symptoms.
NCCAM Research on CAM for Menopausal Symptoms
NCCAM supports a number of studies on CAM treatments (such as botanicals and mind-body practices) for menopausal symptoms, as do some of the other institutes and centers at NIH. Recent examples of NCCAM-funded projects include:
In addition, NCCAM and other NIH components are cofunding an initiative to establish a network of research centers looking at potential new treatments for menopausal symptoms.
