Why Are My Toenails Turning Yellow?

Common Causes of Yellow Toenails

• Toenail fungus: Can cause yellowing, thickening, brittleness, and crumbling.
• Poorly fitting shoes: Repeated pressure and friction can damage toenails and change their appearance. 
• Nail polish: Dark polish can temporarily stain the nail surface.
• Aging: Toenails may become thicker, more brittle, or discolored over time. 
• Medical conditions: Conditions such as psoriasis can also affect nail color and texture. 

How Can You Treat Yellow Toenails?

Treatment depends on the cause. Fungal infections may require prescription antifungal medication, while discoloration from shoe pressure may improve by wearing properly fitted footwear. Keeping feet clean and dry and trimming nails correctly can also help maintain healthy toenails. 

When Should You See a Podiatrist?

If your toenails remain yellow, become thick or brittle, separate from the nail bed, or cause pain, a podiatrist can evaluate the cause and recommend appropriate treatment. Early evaluation is especially important if you have diabetes or poor circulation. 

Healthy feet starts with healthy nails. If you notice persistent toenail discoloration, schedule a podiatry appointment to find out what is causing it.
