Nail Diseases

Your toenails and fingernails protect the tissues of your toes and fingers. They are made up of layers of a hardened protein called keratin, which is also in your hair and skin. The health of your nails can be a clue to your overall health. Healthy nails are usually smooth and consistent in color. Specific types of nail discoloration and changes in growth rate can be signs of lung, heart, kidney, and liver diseases, as well as diabetes and anemia. White spots and vertical ridges are harmless.

Nail problems that sometimes require treatment include

  • Bacterial and fungal infections
  • Ingrown nails
  • Tumors
  • Warts

Keeping your nails clean, dry, and trimmed can help you avoid some problems. Do not remove the cuticle, which can cause infection.

Nonsyndromic congenital nail disorder 10 Nonsyndromic congenital nail disorder 10 is a condition that affects the fingernails and toenails. Affected individuals have extremely thick nails (onychauxis) that separate from the underlying nail bed (onycholysis) and can appear claw-like. Some fingers and toes may be missing part of the nail (hyponychia).In affected individuals, the nails are often abnormal from birth. However, the abnormalities may not be noticeable until later in childhood because the nails tend to grow more slowly than normal.Individuals with nonsyndromic congenital nail disorder 10 do not have any other health problems related to the condition.
