As we age, it is not uncommon to notice ridges on our fingernails. These vertical furrows that run from the tip of the nail to the cuticle are often referred to as longitudinal striations or bands. While they are usually harmless, it’s important to understand what these ridges could potentially indicate.

Vertical Ridges and Aging

Slight vertical ridges in fingernails are quite common among older individuals. They are believed to be a result of the natural slowing down of cell turnover. Simply put, the process of new skin cells rising up to replace dead cells on the surface of the skin is not as efficient as it used to be. As a result, these ridges may form.

When to Be Concerned

Although vertical ridges are typically due to the natural aging process, there are instances where they may be a sign of an underlying medical condition. If you notice other changes in the texture of your nails along with the ridges, it could be an indication of a health issue. For example, in conditions like trachyonychia (twenty-nail dystrophy), the ridges may appear shiny or brittle. Iron deficiency anemia could also trigger concave or spoon-shaped nails along with vertical ridges.

Horizontal Ridges: Beau’s Lines

Deep horizontal ridges known as Beau’s lines are a more concerning symptom. These often indicate serious medical conditions and can even halt nail growth until the underlying issue is treated. For instance, acute kidney disease may be present if Beau’s lines are observed. Additionally, a 2023 research review found that certain medications, particularly chemotherapy drugs, were a common cause of Beau’s lines. Other causes included diseases like mumps, parathyroid disease, unmanaged diabetes, syphilis, respiratory conditions, prolonged high fevers, zinc deficiency, trauma, and infection.

Seeking Medical Attention

If you experience changes in your nails due to a recent injury, it may be wise to wait a few weeks to see how your nail and finger heal before seeking medical attention. However, in more severe cases such as a clean or ragged cut through the nail, a crushed or torn-off nail, or bleeding under the nail, it is important to see a doctor as soon as possible.

For nail changes not related to an injury, it is still advisable to be evaluated by a doctor. They will examine your nails and inquire about any other symptoms you may be experiencing. Blood and urine tests may be ordered if there is a suspicion of kidney disease, diabetes, or nutritional deficiencies. A dermatologist may also be consulted if the ridges are suspected to be a result of a skin condition, and in some cases, fingernail clippings may be analyzed in a lab to check for signs of infection.

Addressing Nail Ridges

Since fingernail ridges are often an indication of underlying health problems, treating the underlying cause is key. For instance, successfully managing blood sugar levels can help reduce horizontal ridges in individuals with diabetes. Skin conditions like eczema may require moisturizers or topical ointments to alleviate symptoms. In cases where nutritional deficiencies are the cause, dietary changes or supplements may be recommended.

It’s important to consult a dermatologist for personalized advice on nail care and treatment. They can provide guidance on how to address the ridges without causing further damage. Remember, paying attention to changes in your nails and seeking appropriate medical attention is crucial, as these changes could be early signs of a more serious medical condition.

Frequently Asked Questions
