Is Toenail Fungus Caused by Mold or Fungi?

Toenail fungus, medically known as onychomycosis, is caused by fungi, not mold. The primary culprits are dermatophytes, a group of fungi that thrive in warm, damp environments like sweaty socks or moist shoes. Yeasts and non-dermatophyte molds can also sometimes lead to nail infections, but these are far less common. The difference lies in how these organisms function. Dermatophytes specifically feed on keratin, the protein found in your nails and skin, making them especially suited to causing nail infections. Mold, although technically a type of fungus, usually grows on organic material like wood or food, and is not typically responsible for nail infections in healthy individuals. If you notice thickened, discolored, or brittle nails, it could indicate toenail fungus. Left untreated, the infection can worsen over time. It is suggested you consult a podiatrist for proper diagnosis and appropriate treatment options.

Toenail Fungus Treatment

Toenail fungus is a condition that affects many people and can be especially hard to get rid of. Fortunately, there are several methods to go about treating and avoiding it.

Antifungals & Deterrence

Oral antifungal medicine has been shown to be effective in many cases. It is important to consult with a podiatrist to determine the proper regiment for you, or potentially explore other options.

Applying foot powder on the feet and shoes helps keep the feet free of moisture and sweat.

Sandals or open toed shoes – Wearing these will allow air movement and help keep feet dry. They also expose your feet to light, which fungus cannot tolerate. Socks with moisture wicking material also help as well.
