Your nails are more than just a part of your appearance—they're a window into your overall health. Changes in nail texture, strength, or appearance can provide important clues about your body’s nutritional status and even underlying health conditions.
Common Signs and What They May Indicate
1. Brittle or Weak Nails
Possible Causes:
- Nutrient Deficiency: Low levels of biotin, iron, or zinc.
- Dehydration: Lack of moisture due to excessive hand washing or harsh chemicals.
- Thyroid Disorders: Both hypothyroidism and hyperthyroidism can lead to brittle nails.
What to Do:
- Incorporate foods rich in biotin (eggs, nuts, seeds) and iron (spinach, red meat, lentils).
- Use a nail moisturizer or cuticle oil to restore hydration.
- If the condition persists, consult a doctor for thyroid testing.
2. Ridges on Nails
Vertical Ridges:
- Often a normal sign of aging or minor dehydration.
Horizontal Ridges (Beau’s Lines):
- May indicate illness, high stress, or a temporary halt in nail growth due to fever or malnutrition.
What to Do:
- Maintain a balanced diet rich in vitamins and minerals.
- Monitor for other symptoms that may indicate an underlying condition.
3. White Spots
Possible Causes:
- Minor trauma to the nail bed.
- Zinc or calcium deficiency.
- Fungal infections (less common).
What to Do:
- Add zinc-rich foods like pumpkin seeds and whole grains to your diet.
- Ensure your nails are protected during physical activities.
4. Yellow or Discolored Nails
Possible Causes:
- Smoking or exposure to harsh nail products.
- Fungal infections.
- More severe cases may indicate respiratory or liver issues.
What to Do:
- Avoid harsh chemicals and switch to gentler nail products.
- Seek medical advice if discoloration is persistent or worsening.
5. Splitting or Peeling Nails
Possible Causes:
- Overexposure to water or detergents.
- Vitamin deficiency (particularly B vitamins or protein).
