Osteoporosis has no obvious symptoms, which is why they call it a silent disease. Most people don't know they have it until they break a bone after a mild fall.
But if someone in your immediate family has osteoporosis, you're one step ahead of the game—you know your risk might be higher. It's also higher if you're small-framed, regardless of your gender, and if you're white or Asian.
If you're concerned, you don't have to wait to get tested. Just this year, researchers at Stanford developed a genetic screening that can predict your future risk of bone problems.
