Vertical Ridges (Longitudinal Striations):
These lines run from the cuticle to the tip of the nail and are commonly associated with aging. As you age, it’s typical for these ridges to become more prominent due to changes in nail cell turnover. However, they can also result from vitamin deficiencies, particularly iron, folic acid, or protein.
Horizontal Ridges (Beau’s Lines):
Beau’s lines are deep grooves that run side to side across the nail plate. They occur when there’s a temporary interruption in nail growth, often due to factors like:
• Severe Illness or Fever: Conditions like pneumonia, measles, or high fever can cause these lines.
• Nutritional Deficiencies: Lack of essential nutrients, such as zinc, can lead to Beau’s lines.
• Trauma or Injury: Physical damage to the nail matrix can result in horizontal ridges.
• Chemotherapy: Cancer treatments can disrupt nail growth, leading to these indentations.
As the nail grows, these lines move upward until they reach the fingertip. If new Beau’s lines continue to appear, it’s important to consult a healthcare provider to identify and address the underlying cause.
When to Seek Medical Advice:
While vertical ridges are often harmless and related to aging, horizontal ridges or sudden changes in nail appearance may signal health issues. If you notice:
• Changes in nail color
• Thickness alterations
• Shape modifications
• Persistent horizontal ridges
It’s advisable to consult a dermatologist or healthcare provider. They can assess your overall health and determine if further investigation is needed.
Maintaining Nail Health:
To promote healthy nails:
• Moisturize Regularly: Keep nails and cuticles hydrated to prevent dryness.
• Maintain a Balanced Diet: Ensure adequate intake of vitamins and minerals essential for nail health.
• Protect Nails from Trauma: Avoid activities that can cause nail injury.
