Even the stars aren’t immune to the often-embarrassing issue of fungal nail infections. From actor Danny DeVito to basketball legend Shaquille O’Neal and “Guardians of the Galaxy” star Chris Pratt, celebrities have recently shared their own struggles with thickened, discolored toenails online, highlighting the widespread nature of this condition.
While thickened and discolored nails can stem from various causes, including ill-fitting shoes, trauma, aging, and psoriasis, fungal infections are a frequent culprit. Known medically as onychomycosis, these infections affect approximately 10% of the global population, with rates soaring to 50% among older adults.
These infections primarily target toenails, causing them to thicken, crumble, and discolor. Beyond cosmetic concerns, they can lead to paronychia, a painful inflammation of the surrounding skin, hindering daily activities.
Dermatophytes, fungi that thrive on keratin, are the primary cause of these infections. Yeasts and molds can also contribute. Exposure to fungal spores is heightened in communal spaces like gyms, hot tubs, swimming pools, and changing rooms. Tiny cracks or injuries to the nail, often from everyday wear or poor foot care, provide entry points for these organisms.
Factors such as older age, weakened immune systems, diabetes, and poor circulation increase susceptibility. Closed shoes and sweaty feet create ideal environments for fungal growth.
However, preventative measures can significantly reduce the risk:
- Thoroughly dry feet: Dry your feet after showering or swimming to make them less hospitable to fungi.
- Breathable footwear: Opt for shoes made from breathable materials and moisture-wicking socks.
- Proper shoe fit: Ensure shoes fit correctly and protect nails during activities.
- Protective footwear: Wear flip-flops in public areas like pools and gyms.
Despite these precautions, infections can still occur. Home remedies like Vicks VapoRub, while popular, have limited scientific backing. Although small studies have shown some improvement, more research is needed. Vicks VapoRub is licensed as a cough suppressant and topical analgesic, not a fungal treatment.
Prescription oral medications offer higher success rates (50-80%) but require monitoring for side effects. Topical treatments like nail lacquers are suitable for mild cases but can take 6-12 months for noticeable improvement. Laser therapy, while promising, is costly and requires multiple sessions. Combining oral and topical treatments with regular nail trimming has shown promising results.
Lifestyle changes, along with advancements in medical treatments, offer hope for healthier nails. However, it’s crucial to differentiate between trauma-induced nail thickening and fungal infections. A podiatrist can provide accurate diagnosis.
If you continue to experience fungal nail infections, seeking professional medical advice is recommended.
