Female Athletes Push Bodies to the Limit
By Michele Norris ABCNEWS.com
Many female athletes may be causing irreparable damage to their bodies, even as they train to perfect their sport. These athletes are pushing their bodies while observing the wrong kind of diet, which can develop bone-density disorders.

It's hard to imagine a strong young female athlete having anything in common with a woman in her 70s.

But Anne Torres, an elite runner for 12 years learned otherwise from her doctor. "He told me that I had borderline osteoporosis at age 32," says Torres. "That was a huge shock."

Torres now sees Dr. Aurelia Nattiv, an orthopedic specialist and director of the University of California Los Angeles Osteoporosis Center, who treats dozens of young female athletes with bones even more damaged than Torres'.

"They're 18, 19, 20 [years old]," Nattiv says of the patients she sees, "and they have a hip fracture, just like your post-menopausal grandmother."

Doctors are just beginning to understand this syndrome known as the female athlete triad, often described as "old bones in young bodies." It starts when a young woman pushes herself to swim that extra lap or run that extra mile. And then she dramatically limits what she eats.

"Most of the time, women athletes are told [in order] to get better in their sport, they need to lose weight," says Dr. Carol Otis of the Kerlin-Jobe Orthopaedic Clinic in Los Angeles, who estimates a third of female athletes in sports such as figure skating, running and gymnastics suffer from one or more symptoms of the triad.

Lack of Nourishment Can Stop Menstrual Flow

Otis was one of the first doctors to recognize how over-training and chronic dieting can lead to the second part of the triad: amenorrea, or the point where a woman stops having a period. "The body is conserving energy by turning off the reproductive system and the first sign of that is periods becoming irregular or missing," she explains.

Many mistake amenorrea as a normal part of intensive training. "It didn't bother me I wasn't having a period, to tell you the truth," recalls Torres. "I didn't know there was anything wrong with that."

When a young woman stops menstruating but continues to over-train and under-eat, her body stops making the female hormones needed to build her bones, which leads to the third, most devastating dimension of the triad syndrome: brittle bones that can fracture or collapse.

Dr. Otis inspects an X-ray of a girl suffering from female athlete triad, pointing to the bone which "has become thin enough that it actually has collapsed into a wedge."

"Her posture will be permanently in that position, because the bones have been compressed due to osteoporosis," she adds.

Torres can't reverse a decade of bone loss, but to prevent further damage, she stopped running and has changed her eating habits.

Still, thousands of women continue to push themselves, striving for perfection, in both appearance and performance. And doctors worry they will end up with bodies that may look fit, but are dangerously fragile.

Very interesting article! Thanks for posting. I've never asked my doctor about bone loss, but should probably start.

Susan,

Thanks for posting this - its message can't be emphasized enough, IMHO. The issue of bone loss in female athletes is unfortunately all too common. Stress fractures and osteoporosis and all sorts of other equally appealing consequences can and do result (as the article says).

I remind myself daily to take in enough calcium every day for just this reason, and one of the many reasons I lift weights is to help my bones. There are things we can do to decrease the odds of these nasty things happening.

Natasha

P.S. And now, if you'll excuse me, I'm off to get myself some yogurt. Thanks for the reminder. :)

This article specifically addresses women who exercise to the point of amenorrhea. But my understanding was that, for the rest of us quasi-athletes who engage in regular weight-bearing exercise, that exercise helps to build or at least preserve bone. Anyone?

Yes, for most non-menopausal women weight bearing exercise is bone strengthening.

guavagirl,

To the best of my knowledge, you're correct -- this article is only referring to those athletes who develop amenorrhea, either because their weight/body fat is too low because they're not providing their bodies with enough fuel/fat to for the amount of physical activity they're engaged in.
It's quite possible to be extremely active and not develop amenorreah, provided you're fueling your body properly.
And yes, lots of weight-bearing, physical activity (i.e., running) is definitely good for strengthening/preserving bones.
