Fungal foot infections are a common condition resulting from microorganisms that thrive in warm, moist environments. These fungi feed on keratin, a protein found in your skin, hair, and nails. An infection typically begins on the skin before potentially spreading to the toenails. Here are some ways foot fungus affects your skin and nails:
Types of Foot Fungus
A common type of fungal infection on the feet is athlete’s foot. It often starts between the toes, where moisture is easily trapped. Another common infection is onychomycosis, which is a fungal infection of the nails. This condition happens when fungi get underneath the toenail, leading to changes in the nail’s appearance and structure. Both types of fungus are contagious and grow in similar conditions, meaning one kind of infection may lead to another if left untreated.
Effects on Skin
When fungus infects the skin of your feet, you may notice several changes, such as:
- Itchy, red, and cracked skin, especially between the toes
- A scaly rash that spreads across the sole of the foot
- Small, inflamed blisters
- A burning or stinging sensation
The affected areas are often uncomfortable, and scratching them could break the skin. This creates an entry point for other germs. Over time, the skin may become dry and flaky, peeling away in small pieces.
Impacts on Nails
Fungal infections have noticeable impacts on the toenails. Onychomycosis often begins as a white or yellow spot under the tip of the nail. As the fungus grows deeper, it causes the nail to discolor further, turning it yellow, brown, or even black. The infection typically makes the nail thicken and become difficult to trim.
The nail’s texture can also change, becoming brittle, crumbly, or ragged. Its shape may become distorted, and pieces of the nail could break off completely. In some cases, the infected nail separates from the nail bed. This creates a space where debris accumulates, potentially causing an unpleasant odor.
Consequences of Fungal Spread
A fungal infection that begins in one area can spread to other places. Fungus from the skin can easily transfer to the toenails, and an infected toenail can spread the fungus to the surrounding skin. If you touch the infected area and then touch another part of your body, you may transfer the fungus there. It is also possible to spread the infection to other people through shared surfaces, such as floors, towels, or shoes. For individuals with weakened immune systems or other health conditions like diabetes, a simple foot fungus can potentially lead to more serious secondary bacterial infections.
