Manicures may cover nail imperfections, but polish can’t hide potential health issues that your nails might reveal. Nail health often mirrors overall body health, and abnormalities could point to problems with the liver, lungs, or heart. While some nail stripes are harmless or related to aging, others may signal underlying conditions. Vertical stripes, common with aging, could also suggest deficiencies in vitamins or minerals like B12, magnesium, or iron.

Horizontal ridges, known as Beau’s lines, might reflect trauma, illness, or stress, and if present on all nails, they can indicate serious systemic diseases. White stripes, or Muehrcke’s lines, may appear with kidney or liver problems and low blood protein levels. For many, a balanced diet rich in protein, vitamins, and minerals like biotin and zinc can improve nail health. Pay attention to your nails—they can offer valuable insights into both minor issues and potential health concerns.
