17 signs of kidney trouble you can see—don’t ignore #3!

Take a look at your nails. Normally, the base of your nail (the lunula) is lighter. However, in some people with chronic kidney disease, the top half of the nail appears pink or brown, while the bottom half is white. These are called half and half nails, and while the exact cause isn’t known, there’s a strong link to kidney issues.
