What Do White Fingernails Mean?

White fingernails can be a sign of several underlying health conditions. While some causes are harmless, others may require medical attention. Understanding the different causes and symptoms associated with white fingernails can help you determine when to seek professional help.

Causes of White Fingernails

Harmless Causes:

• Leukonychia: A common, harmless condition that causes white spots or streaks on the nail.
• Ringworm Infection (Tinea Unguium): A fungal infection that can cause white or yellow discoloration of the nail.
• Nail Trauma: Minor injuries to the fingernail, such as hitting it on an object, can cause it to turn white.
• Age: White discoloration of fingernails can occur with age as the nail plate thins.

Medical Conditions:

• Liver Disease: Advanced liver cirrhosis can lead to a buildup of bilirubin in the body, causing white nails.
• Kidney Disease: Chronic kidney failure can also result in white nails due to waste product accumulation.
• Heart Disease: Congestive heart failure can reduce blood flow to the extremities, including the fingernails, causing them to turn white.
• Anemia: Iron deficiency anemia can cause the nails to become pale and white.
• Zinc Deficiency: Zinc deficiency can manifest as white streaks or spots on the nails.
