What color are healthy nails?
Healthy nails are usually pinkish in color without any cracks, indentations, ridges or abnormal depressions. If the toenails are turning yellow, it could be a result of multiple issues. Some may be less serious such as aging or chemicals in nail polish. However, it could also mean there is a more serious systemic medical condition for which medical treatment is required. In most cases, yellow toenails can be treated.
What causes yellow toenails?
The following cause yellow toenails
- Aging: Aging is one of the most common causes of yellow toenails and fingernails. As people grow older, the color, thickness and shape of their nails change. These changes are normal and typically do not require treatment.
- Nail polish: Painting the fingernails frequently with a nail polish, especially with brighter or darker colors such as red, pink, orange or black, can cause yellowish discoloration. Besides the yellow discoloration, there are no other changes in the nails. This is not serious and usually disappears when nail polish is discontinued.
- Medical condition: Yellow toenails can be a symptom of an underlying medical condition. Yellow nails can be caused by jaundice, another infection, fungus or other medical disorders.
- Yellow nail syndrome (YNS) is a rare medical condition. The exact cause is unknown, but patients present with yellow, curved and thickened nails that grow slowly, along with other symptoms such as respiratory problems. The nails may have ridges or indentations in them and can also turn black or green.
- Yellow nails due to a medical condition may also be associated with other signs and symptoms such as
- Change in shape or thickness
If a medical condition is suspected, it is advised to consult a doctor as medical treatment is required.
- Infection: One of the most common causes of yellow toenails in an infection called onychomycosis, which is caused by a fungus that attacks the nails. It is more common in adults. The nails may have yellow and white patches or turn completely yellow or even turn black. The fungal infection is most commonly caused by dermatophytes, which survive on keratin that is found in skin and nails. Poor hygiene, hot and humid weather, diabetes, decreased immunity, etc. increase the risk of fungal toenail infections.
