ce que vos ongles révèlent sur votre santé

Your nails may not reveal the soul, but they can tell a lot about your health. While often overlooked, certain nail changes can serve as important warning signs. Unsightly nails might simply result from poor care, but they can also point to serious underlying health conditions. Recognizing these signs early can help detect problems before they escalate. From nutritional deficiencies to hidden diseases, your nails may offer crucial clues about your overall wellbeing. During physical examinations, doctors frequently check nails because alterations in color, texture, or growth patterns can signal various health issues. Even subtle changes—such as unusual coloration, abnormal shapes, or changes in thickness—might be your body’s way of calling for attention.

1. Yellow Nails

Yellow nails are most often caused by fungal infections, which are generally treatable. If left untreated, the infection can lead to permanent nail damage and even cause the nail to separate from the nail bed. If antifungal medication doesn’t resolve the discoloration, it could indicate thyroid disorders, diabetes, or in rare cases, cancer. Yellowing typically begins at the nail tips and gradually spreads toward the base. Toenails are more commonly affected due to the warm, moist environment inside shoes, but fingernails can also turn yellow. Smoking, certain medications, and frequent use of nail polish can contribute to yellowing as well. Start with over-the-counter antifungal treatments. If there's no improvement after several weeks, consult a doctor for accurate diagnosis and appropriate care.
