Explanation
White lines on the nails, also known as leukonychia, can have different causes. They might appear as horizontal or vertical lines and can be full or partial. These lines can result from minor injuries to the nail, infections, or even systemic health issues.
Types of Leukonychia
- Total Leukonychia: The entire nail appears white.
- Partial Leukonychia: Only parts of the nail are white.
- Transverse Leukonychia: Horizontal white lines across the nail.
Possible Causes
- Injury: Small injuries to the nail can cause white spots or lines.
- Infections: Certain infections can lead to changes in nail color.
- Health Conditions: Some health conditions, like kidney or liver disease, may also cause these changes.
If you notice changes in your nails, it may be worth discussing with a healthcare provider to rule out any serious underlying conditions.
