I'm worried about my frequent forgetfulness. Is there any way to improve it?

There are often times when I go out to the living room because I need something, but then I think, "Oh, what did I come here for?" and can't remember.
Sometimes, after doing other things and some time passes, I suddenly remember, "Ah, I came here to get something earlier."
I have frequent forgetfulness, and I am worried it might get worse.
I would like to know if there are any easy ways to overcome forgetfulness and improve memory in everyday life.
