Nails can tell us a lot about our overall health. Changes in nail texture, color, and shape can indicate certain health conditions. Here are 12 nail symptoms that can indicate health issues:.

1. Discolored Nails

If your nails are a yellowish color, it could indicate a fungal infection. If your nails are a bluish color, it could indicate poor circulation or oxygen levels in your blood.

2. Clubbing

Clubbing is when the tips of your fingers become enlarged and your nails curve around your fingertips. This can indicate lung or heart problems.

3. Spoon Nails

Spoon-shaped nails, or nails that are curved upward at the edges and have a concave center, can indicate iron deficiency anemia.

4. White Spots

While they’re often thought to indicate a lack of calcium, white spots on nails are usually just a sign of trauma to the nail itself.

5. Beau’s Lines

Beau’s lines are deep grooves that run horizontally across your nails. They can indicate a variety of conditions including malnutrition, injury, or illness.

6. Rippled Nails

If your nails appear rippled or pitted, it may be a sign of psoriasis or inflammatory arthritis.

7. Brittle Nails

If your nails are easily cracked, split, or broken, it could indicate a thyroid problem or a fungal nail infection.

8. Dark Lines Beneath Nails

Dark lines beneath nails can indicate a type of skin cancer called melanoma. If you notice a dark line beneath your nail that doesn’t go away, consult a doctor immediately.
