Sauna/sweat therapy.g Healthy diet: minimize exposure to heavy metals, pesticides, and xen- obiotics to avoid exacerbating compromised bone integrity.
Note: These treatments may be useful for current and recent users of hormonal and IUD contraceptives.
aProbiotics: A growing body of evidence supports the use of probiotics in the prevention and treatment of urogenital infections as well as in the enhancement of immunity. Li et al recently published an article, "The Importance of Vaginal Microbes in Reproductive Health," stating, "The use of probiotic lactobacilli vaginal y and oral y has shown great promise in helping to restore and maintain a healthy vagina, and studies have shown that certain strains have the capacity to interfere with…inflammatory pathway[s]…"72 cPhytoestrogen cream: While the research is limited, two clinical trials have supported the use of a gel containing hyaluronic acid, liposomes, phytoe- strogens from Humulus lupulus extract, and vitamin E for the relief of atrophic vaginitis. These studies demonstrated improvement of vaginal atrophic symptoms without the side effects that are commonly attributed to hormonal creams.73 dPhytoestrogen foods (isoflavones and lignans): "Phytoestrogens have a similarity in structure with the human female hormone 17-β-estradiol, which can bind to both alpha and beta estrogen receptors and mimic the action of estrogens on target organs, thereby exerting many health benefits when used in some hormone-dependent diseases."74 An animal study using ovariectomized ewes demonstrated an improved clearance rate of progesterone.75 "Dietary intake of these so-called phytoestrogens has been associated with positive effects on menopausal complaints, hormone-related cancers, and ePueraria mirifica and Saururus chinensis: P mirifica was found to have an osteogenic effect on bone in ovariectomized rats, and a recent study con- firmed these findings by demonstrating the herb's influence on estrogen-receptor-dependent osteoblast differentiation rather than proliferation.77 "It was concluded that S chinensis treatment could prevent ovariectomized-induced loss of bone mass and deterioration in trabecular microarchitecture by suppressing bone turnover, thereby maintaining bone structural integrity. Furthermore, no stimulation or proliferation of uterine tissue was noted."78 Given that S Chunensis interferes with bone turnover, future research might explore the intermittant use of the herb. This approach could theoretical y support bone remodeling.
fEssential Fatty Acids: Omega-3 in a higher dose with respect to omega-6, helps to protect bone mass by preventing the formation of osteoblasts.79 A recent study demonstrated that omega-3 in combination with aerobic exercise was synergistic in decreasing inflammation and increasing BMD.80 Another study showed a positive correlation between omega-3 (DHA + EPA) and BMD in postmenopausal Korean women.81 gSauna/sweat therapy: Bone and adipose tissue are storage sites of xenobiotics and xenoestrogens. Consequently, exposure may influence bone integ- rity. Sweating assists with decreasing the xenobiotic load. Additional y, unpublished data from the prospective 1999 Toronto Osteoporosis Prevention Study, which investigated the influence of lifestyle factors on BMD in 669 Caucasian women aged 18-35, revealed a slightly significant correlation between increased BMD and sweating as an independent variable.
