Aside from showing your hygienic state, do you know that your nails can give clues about your health? The state of your nails can tell whether you have a fungal infection, kidney diseases, liver diseases or even low oxygen levels.

When people pay attention to more functionally important parts of the body like the liver, kidney, oral cavity or eyes, it becomes easy to forget seemingly less essential parts like the nails.

Always check your fingernails; they might be telling you something you don’t know about the state of your health.

The nails are made up of a protein called keratin. They grow from underneath the cuticles. As new nail cells are formed, the older ones become hardened and eventually get pushed out towards the tips of the fingers.

Fingernails grow slowly, and for that reason, they can give clues about what is happening in the body.

You didn't even mentioned how.
