Noticed vertical ridges on your nails lately? While often harmless, these lines can sometimes signal underlying health issues or nutritional deficiencies. Here’s a deeper look into what causes vertical ridges on nails and when you might want to consult a healthcare professional.

1. Normal Aging

Vertical ridges, which may become more prominent as you get older, are commonly a part of the natural aging process. These ridges typically run from the cuticle to the tip of the nail and are generally harmless.

2. Nutritional Deficiencies

A lack of certain nutrients can also lead to changes in nail health, including the appearance of vertical ridges. Important nutrients for nail health include:

Protein: Nails are primarily made of a protein called keratin. A protein deficiency can make it difficult for your body to build strong, healthy nails.

Vitamin B12: A deficiency in B12 can cause changes in nail color and texture.

Iron: Low iron levels can lead to vertical ridges and in some cases, spoon-shaped nails.

3. Dehydration

Inadequate hydration can affect your entire body, including your nails. When you don’t drink enough water, your nails can become brittle and ridged. Maintaining good hydration is essential for keeping your nails and skin healthy.

4. Nail Injury

Trauma to your nails, such as a crush injury or chronic picking at your nails, can cause vertical ridges. These injuries can damage the nail bed and disrupt normal nail growth.

5. Skin Diseases

Certain skin conditions, especially those that affect the cuticles or the skin around the nail, such as psoriasis or eczema, can cause nail abnormalities including ridges.

6. Circulatory Diseases

Poor circulation can limit the blood supply to your nails, affecting their growth and appearance. Conditions such as peripheral arterial disease or other heart problems can manifest symptoms in the nails.

Conclusion

Vertical ridges in your nails are usually a harmless sign of aging. However, if you notice other changes like discoloration, thickness changes, or if the ridges are accompanied by other symptoms, it might be a good idea to consult a healthcare provider. Eating a balanced diet, staying hydrated, and protecting your nails from injury can help maintain their health and appearance. Remember, your nails can be a window to your overall health, so it’s worth paying attention to them.
