Your nails can reveal diseases in your body

It is important to examine our nails regularly and check for discolorations and changes in the shape and structure of the nails. Our nails are rarely the first clues to a disease, but it is nevertheless valuable to know that certain diseases manifest in our nails. Being able to discern between the serious and less serious signs of our nails will allow us to know when to seek advice and when we can take action to solve the problem ourselves. In general, nail health remains an important part of a healthy body.

To notice abnormalities, we must first become familiar with what a normal nail should look like. A healthy nail is semi-transparent, light pink in color, and intact in the nail bed. The white crescent (or lunula) is visible just above the cuticle. Examining your nails may not provide an absolute diagnostic tool, but if you notice the changes below and have any concerns about them, talk to your doctor.
