For example, very pale nails may indicate illnesses such as anaemia, congestive heart failure or liver disease. Random white spots on nails are usually not harmful, but if the nails are mostly white with darker rims, this can indicate liver problems. Nail health is closely associated with how well your body is functioning in other areas.
