Lifestyle Changes

Simple changes in lifestyle and diet can help control menopausal symptoms such as hot flashes. Avoid hot flash triggers like spicy foods, hot beverages, caffeine, and alcohol. Dress in layers so that clothes can be removed when a hot flash occurs. For vaginal dryness, moisturizers, and non-estrogen lubricants, such as KY Jelly, Replens, and Astroglide are available.

Healthy Diet

When women reach menopause, they are at increased risk for heart disease. A heart-healthy diet is an important way to control cholesterol and blood pressure levels.

In 2007, the American Heart Association (AHA) issued revised diet and lifestyle recommendations. The current guidelines recommend:

• Balancing calorie intake and physical activity to achieve or maintain a healthy body weight. (Controlling weight, quitting smoking, and exercising regularly are essential companions of any diet program. Try to get at least 30 minutes, and preferably 60 – 90 minutes, of daily exercise.)
• Consuming a diet rich in a variety of vegetables and fruits. Vegetables and fruits that are deeply colored (spinach, carrots, peaches, berries) are especially recommended as they have the highest micronutrient content.
• Choosing whole-grain, high-fiber foods. These include fruits, vegetables, and legumes (beans). Good whole grain choices include whole wheat, oats/oatmeal, rye, barley, brown rice, buckwheat, bulgur, millet, and quinoa.
• Eating fish, especially oily fish, at least twice a week (about 8 ounces/week). Oily fish such as salmon, mackerel, and sardines are rich in the omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Consumption of these fatty acids is linked to a reduced risk of sudden death and death from coronary artery disease. Women with existing heart disease may also consider taking a daily dietary supplement of 850 – 1,000 mg of EPA and DHA.
• Limiting daily intake of saturated fat (found mostly in animal products) to less than 7% of total calories, trans fat (found in hydrogenated fats, commercially baked products, and many fast foods) to less than 1% of total calories, and cholesterol (found in eggs, dairy products, meat, poultry, fish, shellfish) to less than 300 mg per day. Choose lean meats and vegetable alternatives (such as soy). Select fat-free and low-fat dairy products. Grill, bake, or broil fish, meat, and skinless poultry.
• Using little or no salt in your foods. Reducing salt can lower blood pressure and decrease the risk of heart disease and heart failure.
• Cutting down on beverages and foods that contain added sugars (corn syrups, sucrose, glucose, fructose, maltrose, dextrose, concentrated fruit juice, honey).
• If you consume alcohol, do so in moderation. The AHA recommends limiting alcohol to no more than 1 drink per day for women.
• The AHA does not recommend antioxidant supplements (such as vitamin E, C, or beta carotene) or folic acid supplements for prevention of heart disease.

Soy

Soy is an excellent food. It is rich in both soluble and insoluble fiber, omega-3 fatty acids, and provides all essential proteins. Soy proteins have more vitamins and minerals than meat or dairy proteins. They also contain polyunsaturated fats, which are better than the saturated fat found in meat. The best sources of soy protein are soy products (tofu, soy milk, soybeans).

For many years, soy was promoted as a food that could help lower cholesterol and improve heart disease risk factors. But an important 2006 review of studies found that soy protein and isoflavone supplement pills do not really have any effects on cholesterol or heart disease prevention. The AHA still recommends soy foods, but not supplements, as a healthy food choice. The benefits of soy on menopausal symptoms are mixed, according to research (see below in Alternative Therapies). A 2006 study reported that increased soy intake does not help reduce the frequency or severity of hot flashes and night sweats.

Soy is high in estrogen-like plant chemicals called isoflavones, which may improve bone health in older women. A 2005 review of 15 clinical trials found that, although the results were mixed, isoflavones appeared to decrease bone loss, especially in younger postmenopausal women. Soy food products, such as tofu, that also contain calcium may be particularly beneficial.

Calcium and Vitamin D

A combination of calcium and vitamin D is important for helping to prevent bone loss.

Calcium. Women should be sure they have sufficient calcium and vitamin D in their diet by consuming low-fat dairy products or calcium-enriched orange juice. Calcium supplements may be another option for some women. For calcium supplements, calcium citrate (Citracal) is better absorbed than calcium carbonate (Tums, Os-Cal) and other types of calcium compounds. Calcium citrate was the first calcium supplement reported to preserve bone density after menopause.

The standard recommended calcium dose for adults age 50 years and older is 1,000 – 1,500 mg per day, depending on risk factors. High doses (over 2,500 mg per day) of calcium supplements may increase the risk for kidney stones. (Because many commercial foods are now fortified with calcium, this upper limit may be easier to reach than people think.)

For years, doctors have recommended that women take supplements of calcium plus vitamin D to help maintain bone density and reduce the risk for fractures. However, a 2006 New England Journal of Medicine study raised some questions about this approach. In the Women’s Health Initiative study, women were randomly assigned to receive either 1,000 mg of calcium carbonate plus 400 IU of vitamin D a day or placebo. The results indicated that daily calcium and vitamin D supplements:

• Improve hip bone density slightly (by 1%)
• Prevent hip fracture, but only for women who consistently take the supplements. (Another 2006 study supported this finding.)
• Do not prevent spine or other types of fractures
• Produce a slight increase in the risk of kidney stones

The medical community has differing views on how to interpret these findings. Some doctors recommend that women over age 60 should still consider taking calcium and vitamin D for bone health. Other doctors feel that due to the risks of kidney stones, supplements are beneficial only for women (especially those over age 70) who do not get enough calcium in their diets. Ask your doctor whether you should take calcium supplements.

Vitamin D. Vitamin D is necessary for the absorption of calcium in the stomach and gastrointestinal tract and is the essential companion to calcium in maintaining strong bones. Some studies suggest that vitamin D protects against osteoporosis only in combination with calcium. Vitamin D is manufactured in the skin using energy from the ultraviolet rays in sunlight. It can also be obtained from dietary supplements. As a person ages, vitamin D levels decline. Levels also fall during winter months and when people have inadequate sunlight. Pollution may also contribute to less sunlight and declining vitamin D levels.

Daily dosage guidelines vary. General recommendations include:

• 400 IU for people age 50 - 60
• 600 IU for those over age 70 who do not have sufficient exposure to sunlight. (Some evidence suggests that higher doses of vitamin D -- up to 800 IU per day -- may help prevent fractures in people with osteoporosis.)
• 800 – 1,000 IU for adults over age 50 (the amount recommended by the National Osteoporosis Foundation)

Drinking milk fortified with vitamin D and sunlight exposure supply most people's need for vitamin D. (One cup of whole milk provides about 100 IU of vitamin D.) Oily fish (sardines especially, as well as salmon, fresh tuna, and mackerel) are also important dietary sources of vitamin D. Wild salmon has a much higher vitamin D content than farmed salmon.

Alcohol

Effect on the Heart. One drink a day in women who are not at risk for alcohol abuse may be beneficial for the heart. Red wine in particular contains a substance called resveratrol, which is classified as a phytoestrogen and has estrogen-like effects. Effect on Bones. Alcohol has different effects on bones depending on how much is consumed. A 2004 study found that moderate wine consumption was linked to improved bone mineral density in postmenopausal women. Alcohol, in moderate amounts, may increase estrogen levels. Excessive drinking, however, has been associated with brittle bones.

Effect on Breast Cancer. Women who drink face an increased risk for breast cancer, but the risk associated with mild-to-moderate drinking is small.

Controlling Weight Gain

Many women need to increase physical activity and reduce caloric intake before and after menopause. Weight gain is common during these years, and it can be sudden and distressing, particularly when habitual exercise and eating patterns are no longer effective in controlling weight. Gaining weight around the abdomen (the so-called apple shape) is a specific risk factor for heart disease and diabetes and many other health problems. A 2007 study suggested that calcium and vitamin D supplements may help prevent weight gain in postmenopausal women. The benefit was greatest for women who had not been getting enough daily calcium in their diets.

Exercise

For protection against all aging diseases, women, whether or not they are taking hormone replacement therapy, should pursue a lifestyle that includes a balanced aerobic and weight resistance exercise program appropriate to their age and medical conditions. Brisk walking, stair climbing, hiking, dancing, and tai chi are all helpful. Several studies report that exercise can help control hot flashes. A healthy diet plus regular, consistent exercise can also help ward off the weight gain associated with menopause. Weight-bearing exercises are specifically helpful for protecting against bone loss. Women should strive for at least 30 minutes of exercise each day (for weight loss, 60 – 90 minutes is preferred). While more exercise is better, any exercise is helpful. A 2007 study showed that postmenopausal sedentary women who exercised only 75 minutes a week experienced improvement in fitness levels.

Quit Smoking

If a woman smokes, she should quit. Smoking is linked to a decline in estrogen levels. Women who smoke experience menopause about 2 years earlier than nonsmokers. Smoking doubles a woman’s odds of developing coronary heart disease and is a major risk factor for osteoporosis.

Other Heart-Health Recommendations

Aspirin. The American Heart Association recommends daily low-dose aspirin for all women age 65 years and older who can safely take aspirin. High-risk women may require 75 – 325 mg per day; lower-risk women may benefit from 81 mg a day or 100 mg every other day.

Alternative Therapies

There are many unproven methods for relieving menopausal symptoms, some more effective than others. Acupuncture, meditation, and relaxation techniques are all harmless ways to reduce the stress of menopause, and some people report great benefit from these practices.

Women often try herbal or so-called natural remedies to treat menopausal symptoms. There have been numerous studies conducted on various herbal products and other complementary and alterative therapies. These studies have not found that these approaches have any benefit. Some can have adverse side effects.

Many studies have researched plant estrogens (phytoestrogens), which are generally categorized as isoflavones (found in soy and red clover) and lignans (found in whole wheat and flaxseed). No evidence to date indicates that phytoestrogen supplements provide any benefit for hot flashes or other menopausal symptoms. Nevertheless, foods containing them may be healthful.

Supplements containing specific isoflavones found in soy -- typically the estrogen-like compounds genistein and daidzein -- do not appear to provide any benefits compared to the whole soy protein. Taking them separately may, in fact, cause harm, including a possible increase in estrogen-related cancers.

The following herbs are sometimes use for menopausal symptoms and carry certain risks:

• Black cohosh (Cimicifuga racemosa), also known as squaw root, is the herbal remedy most studied for menopausal symptoms. Although it contains a plant estrogen, this substance does not act like an estrogen in the human body. Studies have shown mixed results in preventing hot flashes. A rigorous 2006 study found that black cohosh worked no better than placebo for treating hot flashes and night sweats. While it may be ineffective, black cohosh appears to be safe. Headaches and gastrointestinal problems are common side effects.
• Dong quai (Angelica sinensis) does not appear helpful for hot flashes or other menopausal symptoms. Do not use dong quai with blood-thinning drugs, such as warfarin, because it may cause bleeding complications.
• Ginseng (Panax ginseng) may help menopausal symptoms of depression and sleep problems, but it has no effect on hot flashes.
• Kava (Piper methysticum) may relieve anxiety but it does not help hot flashes. This herb is generally considered unsafe, due to several reports of liver failure and death, especially in people with liver disease.
• Wild yam (Dioscorea villosa) is an herb sometimes used for menstrual problems as well as menopausal symptoms. It contains a plant progesterone. However, like black cohosh, there is no evidence that the human body can convert this substance into a hormone. Patients should be aware that some commercial herbal wild yam products contain prescription progesterones.
• Dehydroepiandrosterone (DHEA) is a weak male hormone secreted by the adrenal gland. It is available as a dietary supplement. DHEA has no benefit for hot flashes and may increase the risk of breast cancer.

Herbs and Supplements

Generally, manufacturers of herbal remedies and dietary supplements do not need FDA approval to sell their products. Just like with drugs, herbs and supplements can affect the body's chemistry, and therefore have the potential to produce side effects that may be harmful. There have been a number of reported cases of serious and even lethal side effects from herbal products. Patients should check with their doctors before using any herbal remedies or dietary supplements.
