A prolapse is when a part inside the body slips down from the place where it usually sits. The organ is still attached; it has not fallen off — the muscles and tissue that hold it up have grown weak, so it droops.

A prolapse is when指身體裡的一個部位 a part inside the body slips down從原本的位置 from the place where it usually sits往下滑。The organ is still attached器官還是連著的；it has not fallen off並沒有整個掉下來——the muscles and tissue that hold it up have grown weak是撐著它的肌肉和組織變弱了，so it droops所以才會往下垂。

Doctors talk most often about the womb (a uterine prolapse), but the bladder, the bowel, and a disc in the spine can prolapse too. It is a medical word, used in clinics and health articles, not in casual chat. People also use it as a verb for the same thing: the disc has prolapsed.

Doctors talk most often about醫生最常講到的是 the womb (a uterine prolapse)子宮（uterine prolapse，子宮脫垂），but the bladder, the bowel, and a disc in the spine can prolapse too但膀胱、腸道、還有脊椎的椎間盤也都可能prolapse。It is a medical word這是醫學用詞，used in clinics and health articles用在診間和衛教文章裡，not in casual chat不是閒聊會用的字。People also use it as a verb大家也會把它當動詞用 for the same thing指同一件事：the disc has prolapsed「the disc has prolapsed」（椎間盤突出了）。

Though actually, in everyday talk a back problem of this kind is more often called a slipped disc, even when the doctor writes prolapse. It is not a bone popping out of a joint (that is a dislocation), and it is not the whole body collapsing.

Though actually不過實際上，in everyday talk日常說法裡，a back problem of this kind is more often called這種背部的問題比較常被叫做 a slipped disc「slipped disc」（椎間盤滑脫），even when the doctor writes prolapse就算醫生寫的是prolapse也一樣。It is not它不是指 a bone popping out of a joint骨頭從關節裡跑出來 (that is a dislocation)（那個叫dislocation，脫臼），and it is not the whole body collapsing也不是指整個身體垮掉。
