What Causes Discoloured Toenails?

If you've noticed discolouration of your toenails, you may be wondering what this could mean for your foot health. At Birtley Foot Clinic, located in Birtley, Gateshead, we aim to educate our patients about the various factors that can lead to changes in nail colour. Discoloured toenails are not only a cosmetic concern but can also be indicative of underlying health issues. In this article, we will explore the common causes, symptoms, and treatment options for discoloured toenails.

What Causes Toenail Discolouration?

Several factors can contribute to the discolouration of toenails. These causes can generally be grouped into several categories:

• Fungal Infections: One of the most common causes of toenail discolouration, fungal infections can turn nails yellow, brown, or even black. Conditions such as onychomycosis cause fungal growth under the nail, leading to thickening and discolouration.
• Trauma: Injuries to the toe can lead to blood collection beneath the nail (subungual hematoma), resulting in a dark or purple appearance. Chronic trauma from poorly fitting shoes may also cause toenails to become discoloured.
• Health Conditions: Certain systemic conditions like diabetes, psoriasis, or rheumatoid arthritis can impact nail health. For example, diabetes may cause nails to appear thickened and discoloured due to reduced blood flow and increased risk for infections.
• Environmental Factors: Frequent exposure to moist environments can foster fungal growth, leading to discolouration. Additionally, the use of certain nail polishes or harsh chemicals can also contribute to changes in nail colour.
• Nutritional Deficiencies: A lack of essential vitamins and minerals, such as biotin, zinc, or iron, can affect toenail colour and strength, leading to discolouration.

How Can I Identify Toenail Discolouration?

Identifying the specific cause of toenail discolouration often involves observing other symptoms and changes:

• Texture Changes: Fungal infections may cause nails to become brittle or flaky.
• Odour: An unpleasant smell accompanying discoloured nails might indicate an infection.
• Other Symptoms: Redness, swelling, or pus may accompany discoloured nails in cases of infection or injury.

How Can I Treat Discoloured Toenails?

Treatment of discoloured toenails depends on the underlying cause:

• Fungal Infections: Antifungal medications, either topical or oral, are commonly prescribed to treat nail fungus. In some cases, surgical intervention may be required to remove the affected nail.
• Trauma: If the discolouration is due to injury, rest and elevation can help. Severe cases may require drainage of blood under the nail.
• Systemic Conditions: Managing underlying health conditions through medication, lifestyle changes, and dietary adjustments is crucial. Consulting a healthcare provider for tailored treatment plans is recommended.
• Environmental Care: Reducing moisture and ensuring proper nail hygiene can help prevent infections. Wearing breathable footwear also decreases the risk of fungal growth.
• Nutritional Support: Including nutrient-rich foods in your diet can promote nail health. Supplements may be helpful if deficiencies are identified.

When Should I See a Podiatrist?

If you experience persistent discolouration that doesn't resolve with home remedies, it's essential to consult a podiatrist. Going to a specialist can help determine the cause through comprehensive examination and diagnostic tests. Nail disorders can sometimes reflect broader health issues, making timely intervention crucial.
