12 Nail Changes You Shouldn’t Ignore | Dermatologist Explains

What can your nails actually tell you about your health? In this video, I’m breaking down 12 nail changes—including spoon-shaped nails, Beau’s lines, nail pitting, lifting, yellow nails, Terry’s nails, clubbing, and splinter hemorrhages. Some nail changes are caused by aging, dryness, manicures, or repeated trauma. Others may provide clues about iron deficiency, psoriasis, thyroid disease, kidney or liver disease, and certain heart or lung conditions. I’ll explain which findings are commonly harmless, which deserve more context, and when you should make an appointment. Plus, we’ll discuss one change you should never ignore: a new or changing dark band within the nail. Remember: nail findings are clues—not diagnoses. Do not start iron, thyroid supplements, or nail vitamins based solely on something you noticed in your nails.
