Understanding Toenail Fungus: Causes, Risks, and Effective Treatments
Toenail fungal infections result from overgrowth of fungi that reside in or on the nail, often triggered by moist, warm environments. These fungi can spread from contact with infected individuals or conditions promoting fungal proliferation. The infection develops gradually, making early signs subtle and easy to overlook. Common culprits include dermatophytes, yeasts, and molds, often beginning with athlete’s foot before spreading to nails. Men, adults, especially seniors, and those with compromised immunity or poor circulation are more susceptible to these infections.
What factors increase the risk of toenail fungus?

Factors raising the likelihood include diabetes, circulatory issues, aging (over 65), frequent use of tight shoes or artificial nails, nail or skin injuries, and weakened immune function. Older adults face higher risks due to slower nail growth and brittle nails that allow fungi to invade more easily.
