I talked with my father.

When I was just about to finish eating a dinner, my father came back from his work.

Then I noticed that his arms looked a bit bigger than before. I told him about it.

He said "Maybe it's because of my kidney. Its condition is not so good these days."

"Is it difficult to make it better condition?" I asked.

He said "What I can do is to maintain the <em>status quo</em>."

I wish his condition will could be better.
