Like a Heatwave, Burning in My Heart

It appears that hot flashes affect more than quality of life.

Researchers from the University of Pittsburgh report that hot flashes might actually damage the blood vessesls and increase the risk for atherosclerosis, a form of heart disease characterized by hardening of the arteries.

Study partciipants included 492 women, ages 45 to 58 years, who were participating in the community-based Study of Women’s Health Across the Nation.

The findings, which were published in the eary online edition of the journal Circulation, show a significant increase in calcium deposits and buildup  (i.e. calcification) in the greater coronary artery and aorta in women with hot flashes. In fact, these women were 1.5 times likely to develop calcification than women not experiencing hot flashes.

The researchers report that hot flashes may indicate underlying adverse vascular changes in women.

So what can you do? Because hot flashes may be signs of subclinical or underlying changes in blood vessels that can lead to heart disease, shutting them down is not enough.

Rather, lifestyle changes that promote heart health, such as a healthy diet, regular exercise, weight maintenance or reduction, quitting smoking and moderate alcohol use, seem like smart choices.

In fact, research confirms that lifestyle interventions that include healthy eating and regular exercise can confer protection against and slow different forms of heart disease, including atherosclerosis, if started during perimenipause.

Ch Ch Changes

Among the many changes that occur during menopause, one of the most potentially dangerous is actually being attributed to testosterone rather than estrogen.

Results of a 9-year study study published in the July 28th issue of the Archives of Internal Medicine show that the key hormonal change associated with developing the metabolic syndrome is the steep and progressive domination of testosterone. What’s more, this increase occurs independently of aging and other potential confounding factor (such as smoking, body mass index, ethnicity, marital status and education).

(Metabolic syndrome is a term used to describe the cluster of risk factors (e.g. abdominal fat, high blood pressure and cholesterol levels and insulin resistance) that increases the risk of developing heart disease and diabetes. It affects up to a third of women after age 55.)

Study participants included 949 women recruited from the ongoing  Study of Women’s Health Across the Nation, which is examining factors that affect health and quality of life in women during their middle years.  Women were either premenopausal or in early menopause, and had never used HRT.  Overall, women were shown to have a 1.45 times greater risk of developing the metabolic syndrome in perimenopause and a 1.25 greater risk after menopause.

So, let’s do the math.

1. Metabolic syndrome is closely associated with high blood pressure, obesity, and insulin resistance.
2. Menopausal women are at increased risk for abdominal redistribution and weight gain.
3. Regular exercise/physical activity and a diet that is rich in fruits and vegetables and whole grains, and low in saturated fats, are essential.

With regards to the predominance of testosterone, well, that’s just one more hurdle to overrcome. In the coming weeks, I’ll see if I can find a few evidence-driven tips to counteract this imbalance. In the meantime, we’ve got yet another reason to keep moving!

A Balancing Act

One of the biggest challenges of life is to keep it all in balance, right? This is ever more important as we age and our bones start to thin. Postmenopausal women are three times likelier to fall than men who are the same age. This is due, at least in part, to declining estrogen levels, which not only affect postural stability but also the speed at which spacial information is processed by the brain.

Researchers now say that moderate amounts of exercise may significantly improve balance in postmenopausal women who suffer from osteoporosis.

In this study, 28 postmenopausal women participated in twice-weekly, 30 minute sessions on the treadmills over a month-long period. At the study’s end, significant improvements were seen in all balance tests.

The researchers say that this suggests that exercise is valuable in younger postmenopausal women for reducing fracture risk, risk of falls and reaction time. Walking at a fast pace is one of the safest ways to achieve results.

Check out these earlier posts for additional tips on how to achieve better bone health.  I don’t believe that any of us will end up on a double high wire after an intensive treadmill workout but I do believe that we can all benefit from improved balance!

Got the blues?

Everybody who knows me knows that I’m an exercise junkie. If I don’t have my daily dose, well, I go a bit batty and my mood starts that slow decline into a fetal ball of yuck. Well, good news. Study findings suggests that daily exercise not only helps alleviate the effect of general life-stressors, but it may actually do wonders for symptoms too. What’s more, that regular social interaction between sisters tends to improve overall quality of life.

So the next time the blues start grabbing hold, well, get your body moving…
