Translation of "Bedridden" in Japanese

I was afraid that I was going to become bedridden.

私はそのうち寝たきりになってしまうことを恐れました

Since our father is bedridden, we take turns looking after him.

父が寝たきりなので私たちが交代で面倒をみています。

I’m not saying you have to become totally ripped, but you should at least do some muscle training or you’ll probably end up bedridden before you know it.

別にムキムキになれって言うんじゃないけど、ある程度は筋肉鍛えとかないとそのうち寝たきりになっちゃうよ。
