White spots on nails, also known as leukonychia, are usually harmless and not a cause for concern. They can result from a small injury, like biting your nails or jamming your fingertips, which can cause air bubbles to form under the nail. Other causes of white spots on nails include:
-
Fungal infection: Nail fungus, or onychomycosis, can cause white spots on the nails.
-
Mineral deficiency: Some experts say that white spots on your nails may be a sign that youre deficient in minerals like calcium or zinc.
-
Medications: Certain medications, such as retinoids, antibiotics, or blood pressure medications, can cause white spots on the nails.
-
Liver disease or anemia: White spots on nails can sometimes indicate an underlying health condition, such as liver disease or anemia.
-
Allergies: Allergies to certain products, such as nail polish or nail hardeners, can cause white spots on the nails.
In most cases, white spots on nails are not a cause for concern and will go away on their own. However, if you have large, white spots on multiple nails, it's a good idea to talk to your healthcare provider.
