Horizontal nail lines, known as Beau’s lines, can sometimes appear after periods of major stress on the body. They may be linked to past illnesses, injuries, or significant physical strain. In some cases, they can also be associated with chronic conditions such as diabetes or circulation problems, making sudden changes worth discussing with a healthcare professional.
Vertical ridges are common, especially as people get older, and they are often harmless. However, if the ridges become unusually deep, uneven, or appear alongside other nail changes, they may be connected to nutritional issues such as low iron or vitamin B12 levels. Paying attention to changes over time can help identify when something is different from your normal nail pattern.
