From the Research
Longitudinal ridging, also known as onychorrhexis, in fingernails or toenails is typically a normal sign of aging and usually not a cause for concern, but can also be caused by underlying systemic diseases or infections, as noted in a recent study 1.
Causes of Longitudinal Ridging
The causes of longitudinal ridging can be attributed to various factors, including:
- Aging, which slows down cell turnover in the nail matrix, creating slight variations in nail thickness
- Underlying systemic diseases, such as iron deficiency, psoriasis, or thyroid problems, which can cause changes in nail appearance
- Infections, such as fungal infections, which can cause nail discoloration and brittleness
- Trauma to the nail, which can cause ridging and brittleness
Diagnosis and Treatment
Diagnosis of longitudinal ridging involves a thorough examination of the nails and a detailed medical history, as noted in a study on nail disorders 1. Treatment for longitudinal ridging depends on the underlying cause, but may include:
- Keeping nails moisturized with regular hand lotion or nail oil
- Maintaining good nail hygiene and avoiding harsh chemicals
- Gentle buffing with a fine-grit buffer to smooth out ridges
- Addressing underlying systemic diseases or infections with medical treatment
Importance of Nail Examination
A thorough examination of the nails is essential in diagnosing and treating nail disorders, as well as recognizing underlying systemic diseases, as noted in a study on nail lines 2. Nail changes can be a clue to underlying conditions, and early detection and treatment can improve patient outcomes.
