Have you noticed lines appearing on your nails recently? While they are often harmless, these marks can sometimes signal underlying health issues or nutrient deficiencies. Here’s what causes nail ridges and when you might need to seek medical advice.
1. Aging
As you get older, vertical ridges on your nails may become more visible. These lines, which run from the base to the tip of the nail, are generally a normal part of aging and not a cause for concern.
2. Nutrient Deficiencies
A lack of essential nutrients can affect nail health and contribute to the formation of ridges. Important nutrients for strong and healthy nails include:
- Protein: Since nails are primarily made of keratin (a protein), insufficient protein intake can weaken them.
- Vitamin B12: A deficiency in B12 may alter the color and texture of nails.
- Iron: Low iron levels can lead to vertical ridges and, in some cases, cause nails to develop a spoon-like shape.
- Dehydration: Inadequate water intake affects the entire body, including nails. Not drinking enough water can lead to brittle nails and the appearance of ridges.
3. Nail Injuries
Trauma to the nail, such as crushing injuries or habitual picking, can cause ridges to develop. Damage to the nail bed can affect how the nail grows and its overall texture.
4. Skin Conditions
Certain skin disorders, such as psoriasis or eczema, can impact nail health. These conditions may cause ridges, especially near the cuticles or surrounding skin.
5. Circulatory and Heart Conditions
Poor blood circulation can restrict oxygen and nutrient supply to the nails, affecting their growth and appearance. Conditions like peripheral artery disease or other heart-related issues can sometimes manifest through changes in the nails.
Final Thoughts
Vertical nail ridges are often a natural sign of aging and usually nothing to worry about. However, if you notice additional changes—such as discoloration, thickening, or other unusual symptoms—it may be best to consult a doctor. Maintaining a balanced diet, staying hydrated, and protecting your nails from injury can help keep them healthy. Since your nails can reflect your overall health, paying attention to changes can be beneficial.
