What are common nail disorders?
Many disorders can affect the nails, including:
- Ingrown toenails
- Drugs and tumors
With aging, some nails become brittle and flat and concave, may yellow or split. Infections can involve any part of the nail and may or may not change the nail’s appearance.
Most nail infections are fungal, but bacterial and viral infections occur. Toenails require special attention in older people and in people with diabetes or peripheral vascular disease when they have poor circulation, which increases the risk of injury.
