Osteoporosis is a condition in which the bones become thin and brittle, full of tiny holes like a sponge, so they break more easily. A small fall can break a wrist or a hip; a bone in the spine can crumple with little warning.

Do not mix it with osteoarthritis不要把它跟骨關節炎搞混: that one那個 is a worn, painful joint是關節磨損、會痛; this one這個 is weak bone是骨頭變弱。Exercise that loads the skeleton讓骨骼負重的運動, enough calcium and vitamin D足夠的鈣質和維生素D, and和 sometimes medicine有時候用藥 are the usual talk after a diagnosis是確診後通常會談到的內容; the details細節 belong to a doctor屬於醫生該講的, not to a vocabulary note不是一篇單字筆記該講的。
