Fingernails can reveal a surprising amount about your overall health. While ridges on fingernails are often harmless and simply a sign of aging, they can sometimes indicate underlying health issues or nutritional deficiencies. Understanding the different types of ridges and their potential causes can help you determine whether it’s time to consult a doctor. Here’s what you need to know about ridges on your nails and what they might mean for your health.
Types of Nail Ridges
Nail ridges can be categorized into two main types: vertical ridges and horizontal ridges . Each type has different potential causes and implications.
1. Vertical Ridges
What They Look Like: These run from the base of the nail (cuticle) to the tip and are usually parallel.
Common Causes:
Aging: Vertical ridges are often a normal part of aging, similar to wrinkles on the skin. They typically appear as you grow older and are usually harmless.
Dehydration: Lack of moisture in the body can affect nail health, leading to ridges.
Nutritional Deficiencies: Deficiencies in vitamins like B12, zinc, or iron may contribute to changes in nail texture.
Mild Stress or Fatigue: Chronic stress can sometimes manifest in subtle changes to nail appearance.
2. Horizontal Ridges (Beau’s Lines)
