Nails can reveal various health issues, with changes like dark lines indicating vitamin deficiencies or melanoma, white spots suggesting zinc deficiency, brittleness from biotin or calcium deficiency, yellowing from fungal infections or smoking, and other alterations pointing to liver, kidney, respiratory, or autoimmune conditions. Recognizing these signs can prompt timely medical consultation, but they are not definitive diagnoses.
Our nails can provide valuable insights into our overall health, with various nail changes indicating underlying conditions. Examples include dark vertical streaks (splinter hemorrhages) associated with heart valve infections, horizontal ridges (Beau's lines) linked to major illnesses or chemotherapy, and pitted, discolored nails indicating nail psoriasis. Brittle nails are more common in women and older individuals, while white, yellow, or brown nails may signal a fungal infection. Half-and-half nails (Lindsay's nail) can be a sign of kidney disease. It's important to consult a healthcare provider for proper diagnosis and treatment. Additionally, certain manicure practices, such as cuticle removal, gel manicures, and biotin supplements, may have negative effects on nail health.
