Changes in the color, shape, or thickness of your toenail are often signs of fungal nail infection, also called onychomycosis. Fungal infections are common, especially in warm, moist environments like sweaty shoes or public restrooms.
Signs include:
- Thickened nails
- Yellow, white, or brown discolouration
- Brittleness or crumbling edges
- Distorted shape or separation from the nail bed
Other possible causes include trauma to the nail, psoriasis, or underlying medical conditions. Diagnosis may involve a simple nail clipping sent for lab analysis.
Treatment options include:
- Prescription topical or oral antifungal medications
- Debridement (thinning of the nail) to reduce pressure
- In some cases, laser treatment or nail removal
Early treatment is key, as fungal nails can be stubborn and take months to clear. A podiatrist can guide you toward the most effective approach and help prevent the infection from spreading.
