What Is Toenail Fungus?
Toenail fungus, also called onychomycosis, is a fungal infection that affects the toenails. It can cause the nail to become yellow, white, brown, thick, brittle, crumbly, lifted, or difficult to trim.
Although some patients think of toenail fungus as only a cosmetic issue, it can become uncomfortable, spread to other nails, contribute to skin irritation, and make nail care more difficult. At Foot & Ankle Specialists in West Jordan, Dr. Trevor R. Williams evaluates thick, discolored, or damaged toenails to identify the right treatment approach.
What Causes Toenail Fungus?
Toenail fungus often develops when fungi enter the nail through small cracks, skin irritation, nail trauma, or a previous Athlete’s foot infection. Warm, damp environments such as sweaty shoes, locker rooms, public showers, and tight footwear can increase risk.
Patients may also be more likely to develop fungal nails if they have diabetes, poor circulation, a weakened immune system, repeated nail trauma, or difficulty keeping the feet dry.
How Dr. Williams Evaluates Fungal Toenails
A careful evaluation helps determine whether the nail change is truly fungal or related to another cause. Thick or discolored toenails may also be caused by trauma, psoriasis, pressure from shoes, aging nail changes, or other skin and nail conditions.
Dr. Williams examines the nail thickness, color, shape, surrounding skin, number of nails involved, and any pain or pressure. Testing may be recommended when confirmation is needed before starting a longer treatment plan.
Treatment Options for Toenail Fungus
Treatment depends on how severe the infection is, how many nails are involved, and whether the patient has other foot health concerns. Options may include professional nail trimming, topical antifungal medication, oral medication when appropriate, shoe hygiene, skin treatment for Athlete’s foot, and ongoing prevention.
Toenail fungus often takes time to improve because nails grow slowly. Even after treatment begins, clearer nail growth may take several months to become noticeable.
Preventing Recurrence
Fungal nails can return if the environment that caused the infection remains the same. Keeping feet dry, changing socks regularly, rotating shoes, treating Athlete’s foot, avoiding barefoot exposure in shared wet areas, and disinfecting footwear can help reduce recurrence.
