What Your Toenails Are Telling You—And How to Respond
Have you ever taken a closer look at your toenails and wondered if they’re trying to signal something about your health? Those small cracks, odd colors, or brittle edges might seem like cosmetic issues—but they can sometimes reveal much more. From nutrient deficiencies to fungal infections, your toenails could be offering valuable clues. The good news? Many issues can be addressed at home, once you know what to watch for.
The Basics: What Healthy Toenails Should Look Like
Just like your fingernails, toenails are made of keratin—a protective protein that reflects your body’s internal health. When toenails are healthy, they’re smooth, consistent in color, and free from ridges or damage. If they’re suddenly brittle, discolored, or splitting, something in your lifestyle—or your body—may be off balance.
What Causes Weak or Damaged Toenails?
A variety of factors can lead to nail issues. Here are some of the most common:
Fungal infections: These often cause yellowing, thickening, and brittleness.
Footwear trauma: Tight shoes or repeated impact can stress the nail plate.
Moisture exposure: Prolonged dampness weakens nail structure.
Nutritional deficiencies: Low levels of biotin, zinc, iron, and other nutrients are linked to weak or splitting nails.
Underlying conditions: Psoriasis, thyroid imbalances, or circulatory issues can also affect nail health.
Recognizing the Warning Signs
Some early indicators of nail damage include:
Yellow, brown, or white discoloration
Brittle or crumbly texture
Nails lifting or separating from the nail bed (onycholysis)
Unusual thickness or ridges
Persistent cracking or splitting
Noticing these symptoms early can help you intervene before things get worse.
