Doctor Explains What It Means If You Have Ridges On Your Fingernails


  • What They Look Like: These run side to side across the nail and are more pronounced than vertical ridges.
  • Common Causes:
    • Trauma or Injury: Damage to the nail matrix (the area where nails grow) can cause temporary horizontal ridges.
    • Severe Illness: Conditions like high fever, surgery, or serious infections can disrupt nail growth, resulting in Beau’s lines.
    • Nutritional Deficiencies: Low levels of essential nutrients, such as protein, zinc, or biotin, may lead to horizontal ridges.
    • Underlying Health Issues: Conditions like thyroid disorders, diabetes, or autoimmune diseases can sometimes manifest through changes in nail texture.

Other Nail Changes to Watch For

In addition to ridges, certain nail abnormalities may signal health concerns:

  • Discoloration: Yellow, brown, or pale nails can indicate fungal infections, respiratory issues, or liver problems.
  • Brittle Nails: Dry, cracked nails may point to dehydration, hypothyroidism, or vitamin deficiencies.
  • White Spots: Often caused by minor trauma but can also indicate zinc or calcium deficiencies.
  • Clubbing: Enlarged fingertips and curved nails may be linked to lung or heart conditions.
  • Pitting: Small dents or holes in the nails are often associated with psoriasis, eczema, or autoimmune disorders.

What You Can Do About Nail Ridges

If you notice ridges or other changes in your nails, here are some steps you can take:

1. Stay Hydrated

  • Drink plenty of water to keep your body—and your nails—hydrated. Consider using cuticle oil or moisturizing creams to nourish your nails.

2. Maintain a Balanced Diet

  • Ensure you’re getting enough vitamins and minerals, especially biotin, zinc, iron, and vitamin B12. Foods like leafy greens, nuts, eggs, and lean proteins can support nail health.

3. Protect Your Nails

  • Avoid harsh chemicals, excessive filing, or biting your nails. Wear gloves when doing household chores to protect them from damage.

4. Address Underlying Health Issues

  • If you suspect an underlying condition, consult a healthcare provider. Blood tests can help identify nutritional deficiencies or systemic health problems.

5. Use Nail Strengtheners

  • Over-the-counter nail strengtheners or treatments containing keratin, biotin, or calcium can improve nail texture over time.

When to See a Doctor

While most nail ridges are harmless, you should seek medical advice if:

  • The ridges appear suddenly or worsen over time.
  • You notice other symptoms, such as fatigue, weight loss, or changes in skin or hair.
  • The ridges are accompanied by discoloration, thickening, or pain.
  • You have a history of chronic illness or nutritional deficiencies.

A dermatologist or primary care physician can evaluate your nails and recommend appropriate tests or treatments.


Conclusion: Listen to Your Nails

Your fingernails can serve as a window into your overall health. While ridges are often harmless, paying attention to changes in their appearance can help you catch potential issues early. By staying hydrated, eating well, and protecting your nails, you can maintain their strength and appearance. If you’re concerned about persistent or unusual nail changes, don’t hesitate to consult a healthcare professional for peace of mind.
