Fungal Nail Infection
Fungal nail infections can cause toenails to become thick, discolored, brittle, or difficult to trim. The right treatment depends on how much of the nail is affected and what may be causing the changes.
Common Signs of Fungal Toenails
A fungal nail infection, also known as onychomycosis, can gradually change the appearance and texture of the toenail.
- Thickened or brittle toenails
- Yellow, brown, or white discoloration
- Crumbling or splitting at the edges
- Debris or buildup beneath the nail
- Changes in nail shape or texture
- Separation of the nail from the nail bed
What Causes Fungal Nail Infections?
Toenail fungus develops when fungi enter the nail or surrounding skin. Warm, moist environments can make it easier for the infection to develop and spread.
- Exposure in locker rooms, pools, or public showers
- Athlete's foot that spreads to the toenails
- Nail trauma or repeated pressure
- Feet that remain damp for extended periods
- Sharing footwear or nail-care tools
- Certain health factors that make nail infections more likely
Is It Really Toenail Fungus?
Thick, brittle, or discolored nails can have several possible causes. Dr. Forman evaluates the appearance of the nail, how it has changed over time, and other factors that may be contributing before recommending treatment.
Depending on the situation, confirming whether fungus is present may be an important step before beginning treatment.
Fungal Nail Treatment Options
Treatment depends on the severity of the fungal nail infection, how many nails are affected, and whether the infection has responded to previous care.
Initial Fungal Nail Treatment
Milder fungal nail infections may be managed with a combination of nail care, hygiene changes, and antifungal treatment when appropriate.
Because toenails grow slowly, improvement generally takes time even after the infection is being treated.
Frequently Asked Questions
Common signs of toenail fungus include thickening, yellow or brown discoloration, brittleness, crumbling edges, debris beneath the nail, and changes in nail shape or texture. Because other nail conditions can look similar, an evaluation can help determine whether fungus is actually causing the changes.
Toenail fungus can develop when fungi enter the nail or surrounding skin. Risk factors may include athlete’s foot, exposure to warm and moist environments, nail injuries, damp footwear, and repeated exposure in public pools, locker rooms, or showers.
Fungal nail infections generally do not resolve quickly on their own and may gradually worsen or spread to other nails. Treatment options depend on the severity of the infection and the individual patient.
Fungal nail treatment may include topical antifungal products, nail care and hygiene changes, oral antifungal medication in some cases, or in-office laser treatment. Dr. Forman can recommend an approach based on the extent of the infection and your individual needs.
Fungal nail laser treatment uses controlled laser energy as a non-oral treatment option for affected toenails. The number of treatments and expected response can vary depending on the severity of the infection and how many nails are involved.
