Changes That Happen With Our Fingernails

The body undergoes multiple changes with age, including muscle loss and the development of certain health conditions. Fingernails also start to thicken or become more brittle. For yourself or a loved one, be aware of the following factors when it comes to your nails.

Age can cause your nails to harden, thicken and lose their glossy translucence, which results in a yellow, often dull appearance. As keratin breaks down, nails may also thin and become more fragile, increasing your risks for breakage and fungal infections.

Additionally, fingernail quality can indicate the presence of certain diseases. As such, you’re advised to have your nails examined regularly by a podiatrist. For basic nail care:

  • Get your finger and toenails trimmed and shaped regularly. If you’re unable to yourself, have a professional or loved one do it for you.
  • If your nails start to thicken, apply moisturizer to help make them easier to cut.
  • Pay attention to ridges. Vertical ridges occur with age, but horizontal ridges and pitting can indicate certain health conditions, including a zinc deficiency, certain cardiovascular diseases, a thyroid issue or psoriasis.
  • Pay attention to discoloration. Yellow or gray tones emerge with age but dark patches can indicate a fungal infection, bruising or melanoma.
  • Also be aware of the shape. Certain curves can indicate an iron deficiency or heart, respiratory or kidney issues.
