Items in AFP with MESH term: Hot Flashes
ABSTRACT: With growing concern about the use of hormone replacement therapy, some women are looking for alternative treatments for menopausal symptoms and preventing postmenopausal cardiovascular disease and osteoporosis. In observational trials, exercise has been associated with decreased vasomotor symptoms. One trial suggested that black cohosh may reduce menopausal symptoms. Soy has been shown to decrease vasomotor symptoms, lower lipid levels, and increase bone density. However, large amounts of soy must be consumed, and it is not clear whether soy consumption causes a decrease in cardiovascular events or fractures. The evidence for St. John's wort is equivocal. Fish oil is helpful for secondary prevention of coronary artery disease.
ABSTRACT: Numerous reports in the medical literature and popular media have discussed the effectiveness of various nonhormonal agents in reducing menopausal hot flash symptoms. Data for these therapies are limited, and most of the studies have been conducted in women with a history of breast cancer. Selective serotonin reuptake inhibitors and venlafaxine have been shown to reduce hot flashes by 19 to 60 percent and were well tolerated by study participants. Soy isoflavones reduced hot flashes by 9 to 40 percent in some trials, but most trials showed no difference compared with placebo. Black cohosh and red clover also have had inconsistent results, with some trials showing benefit and some no difference compared with placebo. Soy isoflavones, black cohosh, and red clover were well tolerated in clinical trials. Other agents that have been used to alleviate hot flashes include belladonna/ergotamine tartrate/phenobarbital combination, dong quai, evening primrose oil, gabapentin, ginseng, mirtazapine, trazodone, vitamin E, and wild yam, but few data regarding their effectiveness have been published. Further randomized controlled trials are needed.
Soy: A Complete Source of Protein - Article
ABSTRACT: Soybeans contain all of the essential amino acids necessary for human nutrition and have been grown and harvested for thousands of years. Populations with diets high in soy protein and low in animal protein have lower risks of prostate and breast cancers than other populations. Increasing dietary whole soy protein lowers levels of total cholesterol, low-density lipoproteins, and triglycerides; may improve menopausal hot flashes; and may help maintain bone density and decrease fractures in postmenopausal women. There are not enough data to make recommendations concerning soy intake in women with a history of breast cancer. The refined soy isoflavone components, when given as supplements, have not yielded the same results as increasing dietary whole soy protein. Overall, soy is well tolerated, and because it is a complete source of protein shown to lower cholesterol, it is recommended as a dietary substitution for higher-fat animal products.
Black cohosh. - Complementary and Alternative Medicine
ABSTRACT: The herb black cohosh, or Actaea racemosa (formerly named Cimicifuga racemosa), is native to North America. The roots and rhizomes of this herb are widely used in the treatment of menopausal symptoms and menstrual dysfunction. Studies have demonstrated that this botanic medicine, when standardized properly to the terpene glycoside fraction, appears to be effective in alleviating menopausal symptoms. Adverse effects are extremely uncommon, and there are no known significant adverse drug interactions.
ABSTRACT: The results of recent large clinical trials have led physicians and patients to question the safety of menopausal hormone therapy. In the past, physicians prescribed hormone therapy in an attempt to improve overall health and prevent cardiac disease. Hormone therapy appears to increase the risk of breast cancer when used for more than three to five years; therefore, regulatory agencies now advise that physicians prescribe it only to treat menopausal symptoms such as hot flashes and vaginal atrophy, with the smallest effective dosage and for the shortest possible duration. Although estrogen is the most effective treatment for hot flashes, alternatives such as venlafaxine and gabapentin are effective for some patients. Herbal formulations such as dong quai, ginseng, kava, and dietary soy, among others, do not appear to benefit patients more than placebo. In contrast to systemic estrogen therapy, topical estrogen therapy for vulvovaginal atrophy is more appealing for certain patients because it does not require the addition of a progestogen for endometrial protection. Some have advocated selective estrogen reuptake modulators as alternatives to hormone therapy for the prevention of menopausal osteoporosis. The decision to use either therapy depends on clinical presentation and a thorough evaluation of the risks and benefits, because both have potential detrimental health effects and both are linked to an increased risk of venous thromboembolism.
