When most of us think of the "brittle bone disease" known as osteoporosis, we picture a frail older woman with a broken hip or stooped shoulders. But you can't tell if someone has osteoporosis just by looking at them. Doctors need to review your personal and family history, your habits, as well as a bone density test to find your personal risk.
"It could be an elderly lady, a man, or a younger woman who is fine, but is 5 feet tall and weighs 93 pounds," says Ethel S. Siris, MD, of Columbia University Medical Center in New York.
Weight loss and bone loss can sometimes go hand in hand.
Doctors know that women with anorexia, who severely restrict calories for a long time, are at increased risk for osteoporosis. The eating disorder interferes with hormones needed to maintain bone, not to mention the foods people need to build bone.
But what if you don’t have anorexia? What’s the relationship between osteoporosis and normal dieting? How do you know if you’re at risk for bone loss? What kind of dieting is safe for your...
"When an older woman or man has a fracture, we must see if they have low bone mass or osteoporosis," says Siris. This is the biggest red-flag warning that more fractures can follow.
When Do You Need a Bone Density Test?
A bone density test can diagnose osteoporosis before a broken bone occurs. The National Osteoporosis Foundation recommends this X-ray for:
All women 65 and older
Younger women who have risk factors for osteoporosis
Men 70 and older
Men 50-69 with risk factors for osteoporosis
Some doctors use the FRAX formula (Fracture Risk Assessment Tool) to estimate your chance of breaking a bone within the next 10 years. It adds up past fractures, gender, smoking, alcohol use, and sometimes bone density test results in the hip, as well as other factors.
