（单词翻译）

Osteoporosis literally1 means porous2 bone. It is characterized by loss of bone density3 and the deterioration4 of bone tissue, which makes bones fragile and more likely to fracture. The important thing about osteoporosis is figuring out whether you’ve got it before you injure yourself. And that’s pretty easy to do: there’s a specialized5 test that measures bone density, and based on its results, doctors can prescribe various medications to slow the disease down.
