Onychomycosis is a medical term for a fungal infection of the nails, usually affecting toenails more than fingernails. It’s relatively common, especially in adults and older people.
Causes
- Fungi: Most often caused by dermatophytes (e.g., Trichophyton species), but yeasts and molds can also cause it.
- Risk Factors:
- Poor foot hygiene or sweaty feet
- Wearing tight, non-breathable shoes
- Minor nail trauma
- Diabetes or weakened immune system
- Age (nail growth slows, making infections more likely)
Symptoms
- Thickened nails
- Discoloration (yellow, brown, or white)
- Brittle, crumbly, or ragged nails
- Distorted shape of the nail
- Mild pain or discomfort, especially when wearing shoes
Treatment Options
- Topical Antifungals
- Creams or medicated nail lacquers (e.g., ciclopirox) for mild cases.
- Must be applied consistently for several months.
- Oral Antifungals
- Medications like terbinafine or itraconazole are more effective for moderate to severe infections.
- Usually prescribed for 6–12 weeks; liver function may need monitoring.
- Nail Care & Hygiene
- Keep nails short and clean.
- Wear breathable shoes and moisture-wicking socks.
- Avoid walking barefoot in public places like pools or gyms.
- Laser or Surgical Options
- Laser therapy can help in stubborn cases.
- Nail removal (partial or full) is rarely needed.
Prevention Tips
- Keep feet dry and clean.
- Trim nails straight across and avoid aggressive manicures/pedicures.
- Disinfect nail tools regularly.
- Change socks and shoes frequently to reduce fungal growth.
💡 Key Insight: Onychomycosis is common and treatable, but it requires consistent care. Early treatment prevents nails from becoming thick, painful, or permanently damaged.
