What Vertical Lines on Your Nails Can Reveal About Aging

When Nail Changes May Signal Something Else

Although vertical ridges are often harmless, sudden or severe nail changes can occasionally point to underlying health issues.

Doctors sometimes look at nail health as one small indicator of overall wellness. Significant nail changes may be associated with:

• Vitamin deficiencies
• Dehydration
• Iron deficiency
• Poor nutrition
• Certain thyroid conditions

If ridges appear suddenly or are accompanied by discoloration, splitting, pain, or changes in nail shape, it may be worth discussing with a healthcare professional.
