White Spots on Nails: Normal or a Sign of Illness? Expert Explains Leukonychia

• White spots on nails are medically known as leukonychia, often harmless and disappear with nail growth.
• The most common cause is a minor nail injury, often unnoticed, which later appears as a white spot.
• Nutrient deficiencies (zinc, protein, vitamins) or excessive use of nail polish/removers can also contribute.
• Dr. Rajkumar (Ayush) states they are usually harmless, but advises attention to diet if marks recur.
• Rarely, allergies or fungal infections are causes; consult a doctor if nails thicken, break, or change color.
