Listen to your nails

Your fingernails can be a revealing indicator of overall health. For instance:

• Pale nails can be a sign of anemia, congestive heart failure, liver disease or malnutrition.

• Mostly white nails with dark rims can be a sign of liver problems, like hepatitis.

• Yellow nails are most likely a sign of fungal infection, but in rare cases, yellow nails can indicate thyroid or lung disease, diabetes or psoriasis.

• Dark lines beneath nails should be checked by a physician immediately, as they can be a sign of melanoma.

• Cracked or split nails have been associated with thyroid disease and fungal infection.
