8 Health Warnings to Never Ignore From Your Fingernails

Your nails are a lot more than hardened extensions of your skin. They can tell you whenever there’s something wrong with your body. Your skin, nails and hair contain keratin, a type of fibrous structural protein. It keeps your hair and skin healthy. The outer layer of your fingernails and toenails is called alpha-keratin, and any damage to this layer could be a sign of a health problem.
According to the American Academy of Dermatology (AAD), your nails reflect your health and overall well-being. For instance, any discoloration and thickening may be a sign of liver and kidney disease, heart and lung issues, anemia or even diabetes.
Pay more attention to the condition of your nails, and watch for the following changes:
