The majority of nail changes are not serious. Everyday habits like picking at nails or minor trauma to the nail bed can make ridges appear more pronounced. According to the NHS, common nail issues such as brittleness, discoloration, or changes in shape usually aren’t linked to major health problems.
However, Dr. Perry cautions that deep, severe ridges could be a red flag for more serious conditions, including kidney disease or even diabetes. In such cases, it’s best to seek medical advice.
Other Warning Signs to Watch For
Aside from ridges, other nail symptoms may signal the need for medical attention:
Discoloration (yellow, brown, or white nails)
Loose or lifting nails
Unexplained nail loss
