For a phenomenon that impacts roughly 75 p.c of menopausal American girls, sizzling flashes are nonetheless surprisingly mysterious, with little identified about how they work or what to do about them.
“We don’t have precise solutions — simply a number of theories and questions,” mentioned Dr. Arianna Sholes-Douglas, an obstetrician-gynecologist and creator of “The Menopause Delusion: What Your Mom, Physician and Mates Haven’t Shared About Life After 35.” With the decline in estrogen throughout the menopause transition, the physique’s inside thermostat generally registers the physique as hotter than it’s and units off speedy sweating and a dilation of blood vessels in an try to chill down.
However what triggers that course of and why? It’s unclear. How are sizzling flashes related with different well being points, like cognitive issues and heart problems? Additionally hazy. Remedy choices are restricted to hormones and only one non-hormonal drug authorised by the Meals and Drug Administration. All of which, Dr. Sholes-Douglas added, is a transparent reflection of the scant consideration and little funding dedicated to medical analysis into this section of a lady’s life.
Within the final twenty years, researchers have began to research one other potential supply of aid: weight-reduction plan. The thought stems from research which have discovered that sizzling flashes differ throughout cultures and is likely to be a largely Western expertise. With that in thoughts, researchers have hypothesized that environmental components, like weight-reduction plan, would possibly play a component on this distinction.
However most of the research on dietary interventions are small or inconclusive, mentioned Dr. Stephanie Faubion, medical director for the North American Menopause Society and a director of the Mayo Clinic Middle for Ladies’s Well being. In research which have prompt sure meals scale back sizzling flashes, the mechanisms at work will not be totally understood, she added.
Nonetheless, there isn’t any hurt in adjusting your weight-reduction plan to see if it’d assist handle your sizzling flashes, Dr. Faubion mentioned.
Which meals would possibly assist?
Soy merchandise, like tofu and soybeans, comprise isoflavones, that are chemical compounds that may bind to estrogen receptors within the physique, mentioned Neal Barnard, an adjunct professor of medication on the George Washington College of Medication. For that cause, the considering goes, soy could mimic estrogen. It’s one of many most-studied meals in connection to menopausal signs, and there’s some proof that consuming it is likely to be related to fewer sizzling flashes. However it’s unclear whether or not that’s due to the soy itself or one other mechanism.
In a pair of latest research, Dr. Barnard and his workforce randomly assigned 84 postmenopausal girls who reported average to extreme sizzling flashes to both their common diets or a low-fat vegan weight-reduction plan wealthy in complete grains, vegetables and fruit, together with a day by day half-cup of cooked soybeans. Reasonable to extreme sizzling flashes decreased by roughly 80 p.c in each research.
“The caveat there’s that this was primarily two totally different interventions — they have been on a whole-food, plant-based weight-reduction plan and so they had excessive soy,” mentioned Dr. Faubion. “So what a part of that was liable for these outcomes? We do not know.” The ladies within the examine additionally ended up losing a few pounds, which Dr. Faubion mentioned is noteworthy as a result of some research have proven a correlation between elevated physique fats and sizzling flashes, notably throughout sure levels of menopause.
Additionally of curiosity to researchers are omega-3 fatty acids. However whereas some research have discovered that taking omega-3 dietary supplements appears to scale back the frequency of sizzling flashes, others discovered that they make no distinction. Dietary supplements apart, the Mediterranean weight-reduction plan, which is wealthy in meals containing omega-3s — like flaxseeds, walnuts and fatty fish like salmon — has been proven in some research to be related to fewer sizzling flashes and different menopause signs.
Are there meals to keep away from?
There’s some proof {that a} weight-reduction plan excessive in sugar and fats is related to worse sizzling flashes. Past that, medical doctors usually counsel avoiding sure meals and drinks that seemingly set off a sizzling flash, mentioned Dr. Hoosna Haque, an OB-GYN at Columbia College Irving Medical Middle, reminiscent of “spicy meals, caffeine, alcohol and likewise actually high-concentrated sugary meals and extremely processed meals.”
However, she mentioned, that advice is usually primarily based simply on anecdotal proof, and it’s not totally understood why these meals and drinks would possibly set off a sizzling flash.
“It would simply be as a result of they will trigger spikes and drops in power ranges,” Dr. Haque mentioned. Or as a result of one thing like caffeine can dilate blood vessels — very similar to sizzling flashes do — and should set off an analogous chain of occasions.
In the end, “we counsel sufferers {that a} balanced, nutritious diet could assist relieve signs, but it surely isn’t a therapy,” Dr. Haque mentioned. And wholesome diets “can even have helpful results down the road, with regards to issues like bone well being, weight acquire and cardiovascular well being.”
