Nail fungus, medically called onychomycosis, is a common infection of the fingernails or toenails caused by fungi. It often makes nails thick, discolored, and brittle.
Causes
- Dermatophytes: The most common fungi infecting nails.
- Yeasts or molds: Less common, but can also cause nail infections.
- Risk factors:
- Warm, moist environments (socks, shoes)
- Nail trauma or injury
- Weakened immune system
- Diabetes or circulation problems
Symptoms
- Thickened nails
- Discoloration (white, yellow, or brown)
- Brittle, crumbly, or ragged edges
- Distorted nail shape
- Slight odor in some cases
Treatment
- Topical antifungals: Creams, lacquers, or solutions applied directly to the nail.
- Oral antifungals: For severe infections, prescription tablets (e.g., terbinafine) may be needed.
- Nail care:
- Keep nails trimmed, clean, and dry
- Avoid sharing nail clippers or shoes
- Use breathable footwear
- Laser or surgical options: Rarely, laser therapy or partial nail removal is considered for persistent infections.
💡 Prevention Tips
- Wear moisture-wicking socks and ventilated shoes.
- Keep feet dry after bathing or swimming.
- Avoid walking barefoot in public showers or pools.
- Disinfect nail tools regularly.
