Your nails don’t stay the same as you age. Growth gradually slows, and fingernails and toenails may become duller, more brittle, ridged or noticeably thicker or thinner. Some of these changes are simply part of getting older.
For example, nail growth begins slowing by about 0.5% per year starting around age 25, while age-related changes in circulation, connective tissue and moisture can leave nails more fragile later in life. Toenails can become particularly troublesome, as fungal infections and thickening become increasingly common with age.
But your nails can also offer visible clues about what’s happening elsewhere in your body. Unusual discoloration, pronounced changes in texture or slow growth may accompany nutritional deficiencies or other health problems. Spoon-shaped nails have been associated with anemia and thyroid problems, while clubbing — when nails become enlarged and rounded — may signal a more serious underlying condition.
A new or changing dark streak also deserves attention, since in rare cases it can be associated with melanoma. The important distinction is whether a change develops gradually with age or appears suddenly and looks dramatically different from your other nails.
You can give aging nails a little extra support by protecting the structures that produce them. Keep nails and surrounding skin moisturized, avoid repeatedly exposing them to harsh chemicals and excessive water, and wear shoes that give your toes enough room rather than constantly squeezing them together.
Proper trimming can also reduce the likelihood of painful ingrown toenails as nails thicken. Most importantly, pay attention to changes instead of automatically writing them off as “just getting older.” Your nails are living tissue influenced by circulation, nutrition and overall health, and sometimes a small change at your fingertips can be worth a closer look.
