Fingernails are true indicators of certain health and medical issues, as well as a healthy well-balanced diet. Nails themselves are made out of keratin, which is the same substance the body uses to make hair and the top most layer of skin. Where the nail meets the skin is the cuticle, as most pedicured women know. Cuticles help protect the new part of the nail as it grows out from the nail root and extends the old nail cells out.Fingernails are clues to your overall health:
- Nail Pitting: small depressions in the nail which are most common in people who have psoriasis, a chronic skin condition that produces scaly patches on the skin.
- Nail Clubbing: The tips of the fingers are enlarged, which causes the nail to curve over the fingertip. This could actually be a sign of lung disease, as clubbing can be the result of low oxygen in the blood. It is often associated with inflammatory bowel disease, cardiovascular disease, liver disease and AIDS.
- Spoon Nails: Are soft nails that have become scooped out. The depression is sometimes large enough to hold a drop of water. Spooning nails is an indication of iron deficiency anemia or hemochromatosis, a liver condition that forces the body to absorb too much iron.
- Terry’s Nails: The tip of each nail is dark right before the white edge. This can be the natural cause of aging or the sign of liver disease, congestive heart failure or diabetes.
