Fungal Infections

Among the most common causes for a black toenail is a fungal infection, of which there are a variety of types. These infections will typically turn an individual's toenails pure white or darker shades of yellow, which may allow them to identify the condition before their toenail blackens completely. It's only when debris builds up around the infection that the toenail turns black. Fungal infections occur in toenails more than any other area of the body because of their surroundings. While wearing shoes and socks is essential to ensure feet remain clean and comfortable, doing so also provides an environment where fungus can thrive. Whenever the skin is warm and moist because of shoes and socks, it's possible for a fungus to develop and cause an infection in the nail. However, individuals can prevent these infections as long as they practice good foot care. This includes making sure fungus is treated promptly as if it's left untreated, the fungus can cause permanent damage to the nail and spread to other areas of the body.
