Your nails can reveal a lot about your health. According to Dr. Sara Norris, they act like “a health report card,” showing signs of internal issues before other symptoms appear.
Changes in nail color or shape may signal problems. Pale or white nails can indicate anemia or liver disease. Yellow nails may suggest fungal infections or lung issues. Spoon-shaped nails could mean iron deficiency, while ridges or pits might point to psoriasis or autoimmune disorders.
Brittle or slow-growing nails may result from poor circulation or thyroid problems. Clubbing—thickened and curved nail tips—can be linked to heart or lung disease.
Some nail changes are harmless, caused by stress, aging, or harsh treatments like acrylics and acetone. But ongoing changes shouldn’t be ignored.
To keep nails healthy, eat foods rich in biotin, zinc, iron, and protein. Stay hydrated and avoid overusing harsh chemicals.
If you notice unusual or lasting changes, see a healthcare provider. What seems like a cosmetic issue could be a warning sign of a serious health condition.
