Many people put a lot of effort into keeping their nails perfectly trimmed, cleaned and manicured. If the nails aren’t perfect, the solution is often to cover them up with fake nails or polish. But ignoring such signs and viewing them as only an aesthetic problem could be dangerous to your health. Like your skin, your nails are excellent indicators of what’s going on inside your body. If your nails are healthy (smooth and pink with a slightly curved surface), your body is probably pretty healthy too. But if your nails are discolored, brittle or otherwise appear unhealthy, it may be because of an underlying health problem. Here are 10 signals your nails may be giving you about your health: 1. Brittle nails: This condition signalizes about iron deficiency, biotin deficiency, kidney disorder, thyroid or circulation problems. 2. Pitting: If you see pits on the nails, it could be a sign that you are about to develop, or that you already have, psoriasis. The small depressions on the nail could also be a sign of chronic dermatitis of your fingers. 3. Clubbing: This condition describes when the nails curve down around the fingertips and the nail bed itself bulges. It’s caused by low oxygen levels in the blood and may indicate lung disease. 4. Spoon Nails: If your nails look scooped out, like a spoon, it could be a sign of iron-deficiency anemia and/or lack of Vitamin B12. |
