Experts Decode Toenail Clues: What Your Nails Reveal About Health

What Your Toenails Reveal About Your Health
Your toenails, often overlooked, can signal underlying health issues like diabetes, infections, or nutrient deficiencies, says pharmacist Sheena Bagga. Healthy nails should be smooth, pinkish, and free of discoloration. Here are eight key symptoms to watch for:

1. Yellow Discoloration

Yellow nails often indicate fungal infections or psoriasis. Keep nails clean, dry, and trimmed. Wear breathable shoes and change socks daily to prevent fungal growth.

2. Dark Stripes

Brown or black streaks (melanonychia) might be harmless pigmentation but could rarely signal subungual melanoma, a skin cancer. Avoid nail trauma and seek evaluation for sudden changes.

3. Swollen Toes

Swelling may stem from gout, poor circulation, or salt retention. Gout, linked to uric acid buildup, is manageable with weight loss and a balanced diet. Stay active and hydrate well.

4. White Spots or Nails

White streaks (leukonychia) often result from minor injuries. Fully white nails could indicate systemic issues like liver disease or diabetes. Address iron, zinc, or protein deficiencies through diet.

5. Blue Toenails

Blueish nails with coldness may signal poor circulation or Raynaud’s disease. Exercise improves blood flow; avoid tight footwear and extreme cold.

6. Itchy Toes

Itchy, peeling skin between toes suggests athlete’s foot. Keep feet dry, use antifungal treatments, and avoid sharing towels.

7. Toe Ulcers

Open wounds on toes/foot require immediate care to prevent infection, especially for diabetics. Poorly managed ulcers risk amputation. Clean wounds daily and monitor for redness/swelling.

8. Spoon-Shaped Nails

Concave nails (koilonychia) often indicate iron deficiency or anemia. Consult a doctor for blood tests and potential supplements.

Prevention Tips

• Maintain foot hygiene: Wash daily, dry thoroughly, and wear breathable shoes.
• Trim nails straight across to avoid ingrown issues (see box below).
• Eat a nutrient-rich diet to support nail and overall health.

Spotting Ingrown Toenails

Redness, swelling, or pus around nails may signal ingrowth. Soak in warm water, wear roomy shoes, and avoid cutting nails too short. Seek treatment if infected.

Takeaway
Regular toenail checks can catch early signs of serious conditions. When in doubt, consult a healthcare provider.
