Sometimes, when they begin to struggle, subtle signs begin showing up — often ones we might dismiss. The image above highlights 17 signs of kidney trouble you can actually see or feel. While having one of these doesn’t automatically mean kidney disease, noticing several — or feeling “off” for a while — should prompt a check‑up. Let’s walk through those signs and what they mean.
