Your nails can reveal important clues about your health. Here are 5 changes worth paying attention to:
• Horizontal ridges – often linked to past illness, injury, or stress on the body.
• Vertical ridges – commonly caused by aging, stress, or nutritional deficiencies.
• Dark lines or streaks – can sometimes indicate melanoma (skin cancer) under the nail and should be checked by a doctor immediately.
Other red flags include yellow nails (possible lung issues), spoon-shaped nails (iron deficiency), or clubbing (heart or lung problems).
If your nails have suddenly changed in color, texture, or shape, it’s best to see a doctor. Early detection matters.
