White Spots on Nails: Causes and Treatment

White spots on nails, also called leukonychia, are common and usually harmless. They can appear due to minor nail injuries, nail products, fungal infections, nutritional deficiencies, or certain health conditions.

What Causes White Spots on Nails?

Some common causes include:

- Minor injuries: Hitting, biting, or damaging the nail can cause white spots that usually grow out naturally.

- Nutritional deficiencies: Low levels of certain nutrients, such as zinc, may sometimes affect nail health.

- Fungal infections: Nail infections can cause white patches along with thickening, crumbling, or changes in nail texture.

- Nail products: Nail polish, artificial nails, and strong removers may irritate or damage the nails.

- Health conditions: Conditions such as psoriasis, eczema, kidney problems, or liver problems can sometimes affect the appearance of nails.

How Can White Spots on Nails Be Treated?

Most white spots caused by minor injuries disappear as the nail grows. Keep your nails clean and dry, avoid biting or picking them, and limit exposure to harsh nail products.

If the spots are caused by an infection, nutritional deficiency, allergy, or another health condition, treatment depends on the underlying cause.

When Should You See a Doctor?

Consider seeking medical advice if white spots:

- Affect several nails.

- Keep coming back.

- Cover a large part of the nail.

- Occur with pain, swelling, or nail damage.

- Appear along with other changes in your health.

Most white spots are not serious, but persistent or unusual nail changes should be checked.
