Toenail fungus, medically known as onychomycosis, is a common fungal infection that affects the toenails and surrounding tissues. Fungi thrive in warm, damp environments, making the feet particularly vulnerable to infection. Toenail fungus often begins with a small white, yellow, or brown spot underneath the nail. The affected toenail may become thick, brittle, crumbly, and the nail may become difficult to trim. Early recognition and treatment can help prevent the infection from becoming more difficult to manage.
Common symptoms of toenail fungus include yellow, white, or brown nail discoloration. Additionally, there may be thickened nail tissue and nails that crumble or split easily. Some people may notice an unpleasant odor or tenderness surrounding the affected nail. In more advanced cases, the toenail can separate from the nail bed, creating space underneath the nail where additional debris and microorganisms can collect. Because several nail conditions can cause similar changes, a proper evaluation can help determine whether a fungal infection is responsible.
Several factors can increase the risk of developing toenail fungus. Among them are excessive foot sweating, poor foot hygiene, and wearing tight or non-breathable footwear. Prolonged exposure to moisture can also create an environment where fungi thrive. Walking barefoot in shared locker rooms and public showers, as well as pools and gym areas, can also increase exposure to infectious fungi. People with weakened immune systems or certain underlying health concerns may have a greater risk of developing persistent infections. Toenail fungus can also spread between nails and to other people through contaminated surfaces, towels, or nail tools.
Preventing toenail fungus starts with keeping the feet clean and dry. Change socks regularly, choose breathable footwear, and allow shoes to dry completely between uses. Wear protective footwear in communal wet areas and avoid sharing nail clippers, files, or other personal tools. If you notice persistent toenail discoloration, thickening, and crumbling, it is suggested that you consult a chiropodist for an evaluation and effective treatment solutions.
Toenail fungus can be uncomfortable and unsightly. If you have diabetes or a compromised immune system, it may also be dangerous. To learn more about treatment options, please consult with one of the chiropodists from Complete Family Footcare & Therapy. Our clinicians will assess your condition and provide you with quality foot and ankle treatment.
What Does Toenail Fungus Look Like?
A fungal infection of the toenail may cause the affected nail to become thickened, brittle, crumbly, and yellowish or brown in color. Sometimes the toenail may separate from the nail bed, become deformed, emit a foul odor, or cause pain or discomfort.
What Causes Toenail Fungus?
Toenail fungus is caused by a fungus that infects the nail bed. The fungus lives and thrives in warm and moist environments and is also contagious. Athlete’s foot, which is a fungal infection of the skin, may spread to the nails and cause toenail fungus.
What Treatments Are Available?
Potential treatments for toenail fungus may include oral antifungal medications, topical antifungal medications, such as medicated nail polishes that are applied directly to the affected nail, and laser therapy. Sometimes, a combination of treatments is prescribed.
