If you check your fingernails and toenails for any irregularities, it can be a key to a sick body.
For example, a nail that has become suddenly too thick and dull-looking could suggest a fungal infection.
Are ridges a problem? Horizontal ridges could mean poor eating habits with inadequate nutrition. Other ridges could signal a severe infection.
Thick, rough and yellowed nails could point to possible heart disease and diabetes.
A nail that needs careful watching is one with a widening black or brown streak running vertically. This condition should be check by your doctor since it could indicate possible skin cancer.
Another thing to look out for is a single groove running the length of the nail. This appearance could suggest a possible tumor at the base of that nail.
