looking for a phrase

Hello!
I am looking for a phrases which implies about a person that he has been suffering from poor health from quite sometime and still hasn't recovered.
Thank you.

You could say the person was convalescing from a long illness or that they were on the road to recovery, but still had some way to go.

Hope this helps.

In the US we might say, "He's in bad shape and not getting any better."

He's sinking.
But this means his health is deteriorating quilcky, and will probably die.
