White Spots on Nails: Causes and Treatment

Introduction

Have you ever noticed small white spots or streaks on your nails and wondered what they mean? While they may look concerning, white spots on nails (medically called leukonychia) are usually harmless and often temporary. In this article, we’ll explore the possible causes, when to worry, and how to treat or prevent them.

What Are White Spots on Nails?

White spots on nails appear as small, cloudy dots or streaks on the nail plate. They can occur on one or multiple nails and are typically caused by minor injuries or deficiencies. Most cases are not serious, but sometimes, they may indicate an underlying health issue.

Common Causes of White Spots on Nails

1. Minor Trauma or Injury

The most common cause of white spots is minor damage to the nail bed. This can happen from:

Bumping or hitting your nail

Frequent manicures or gel polish use

Nail biting or picking

Since nails grow slowly, the injury may take weeks to appear as a white spot.

2. Nutritional Deficiencies

A lack of essential nutrients, especially zinc, calcium, or protein, can lead to white spots. People with poor diets or certain digestive disorders may experience this.

3. Fungal Infections (Onychomycosis)

A fungal infection can cause white, yellow, or brittle nails. If the spots spread or the nail thickens, consult a doctor.

4. Allergic Reactions

Some people develop white spots due to an allergy to nail polish, hardeners, or acrylic nails.

5. Serious Health Conditions (Rare Cases)

In rare cases, white spots may indicate:

Liver or kidney disease

Psoriasis or eczema

Heavy metal poisoning (arsenic or lead)

If you notice persistent or worsening white spots along with other symptoms (e.g., fatigue, skin changes), seek medical advice.

When Should You See a Doctor?

Most white spots fade as the nail grows out. However, consult a doctor if:

The spots spread or don’t go away

Your nails become brittle, discolored, or thickened

You have other symptoms like fatigue, swelling, or skin rashes
