Have you noticed lines on your nails recently? While they’re often harmless, these marks can sometimes signal underlying health issues or nutrient deficiencies.
Here’s a closer look at what might cause these lines and when it’s worth consulting a doctor.
1. Aging
As we age, vertical lines on the nails often become more pronounced. These ridges, which run from the base to the tip of the nail, are usually a normal part of aging and not a cause for concern.
2. Nutrient Deficiencies
A lack of certain nutrients can affect nail health, sometimes resulting in vertical ridges. Key nutrients for maintaining healthy nails include:
- Protein: Nails are primarily made of keratin, a type of protein. Insufficient protein intake can hinder your body’s ability to produce strong, healthy nails.
- Vitamin B12: Low B12 levels can cause changes in nail color and texture.
- Iron: An iron deficiency may lead to vertical ridges and, in some cases, spoon-shaped nails.
- Water: Dehydration can weaken nails and make ridges more noticeable. Staying hydrated is essential for healthy nails and skin.
3. Injuries to the Nails
Trauma to a nail—such as crushing it or frequently picking at it—can lead to ridges. Damage to the nail bed can disrupt nail growth and cause visible lines.
4. Skin Conditions
Chronic skin conditions like psoriasis or eczema can impact nail health. These conditions may cause ridges, pitting, or other changes, particularly near the cuticle or surrounding skin.
5. Circulatory and Heart Issues
Poor circulation can reduce the blood supply to your nails, affecting their growth and appearance. Conditions like peripheral artery disease or other cardiovascular problems might show symptoms in the nails.
When to See a Doctor
Vertical lines on the nails are typically harmless and often a natural part of aging. However, you should consult a healthcare professional if you notice additional changes, such as:
- Discoloration
- Variations in thickness
- Pain or discomfort around the nails
- Other unusual symptoms
Tips for Healthy Nails
To maintain strong and healthy nails:
- Eat a balanced diet rich in proteins, vitamins, and minerals.
- Stay hydrated by drinking plenty of water.
- Avoid injuring your nails, and refrain from biting or picking at them.
Final Thoughts
Your nails can serve as a window into your overall health. While most nail changes are harmless, paying attention to them and maintaining good habits can help keep them healthy and looking great. If you’re ever in doubt, don’t hesitate to seek medical advice.
