Ridges in nails can be a sign of a health condition
Ridges in your fingernails or toenails can be a sign of a current or past illness. The ridges may run vertically (up and down) or horizontally (across) your nail. Vertical ridges on your fingernails are called onychorrhexis and are often a result of aging. As you get older, your nails can naturally become ridged, dry, brittle, or thick. However, onychorrhexis can also be a symptom of a health condition.
If you have nail ridges, don’t ignore them. Talk to your provider so you can find out the cause and how to treat it, if necessary. With time and treatment, you may see new, smoother nails grow in. A doctor should examine changes in your nails.
