Toenail ridges refer to longitudinal lines or raised ridges that appear on the surface of the toenails. They can be categorized as either vertical or horizontal ridges.
Vertical ridges are relatively common and often considered a normal part of the aging process. They are more prominent in older individuals and usually do not require any specific treatment. However, in some cases, vertical ridges may be associated with certain medical conditions or nutritional deficiencies.
Horizontal ridges, also known as Beau’s lines, are not as common and may indicate an underlying health issue. They can be caused by various factors such as trauma or injury to the nail, nutritional deficiencies, certain diseases (e.g., thyroid disorders, diabetes), chemotherapy, severe emotional stress, or even systemic illnesses.
If you notice persistent or concerning changes in your toenail ridges, it is advisable to consult with a healthcare professional or dermatologist for a proper diagnosis and appropriate treatment if necessary.« Back to Glossary Index
