Fungal Nails (Onychomycosis)
Strong, Healthy Nails Start with Early Treatment
Fungal nail infections, also known as onychomycosis, are among the most common nail conditions seen by podiatrists. They occur when fungi invade the nail plate and nail bed, causing the nail to become thickened, discolored, brittle, and difficult to trim.
Fungal nail infections rarely resolve on their own and often become more extensive over time if left untreated. Early diagnosis and treatment can improve the chances of successful clearance while preserving the health and appearance of your nails.
What Are the Symptoms?
- Yellow, white, or brown discoloration
- Thickened nails
- Brittle, crumbly, or splitting nails
- Distorted nail shape
- Debris collecting beneath the nail
- Nails lifting away from the nail bed
- Difficulty trimming the nails
- Occasionally discomfort or pain when wearing shoes
Not every thick or discolored nail is caused by fungus. Trauma, psoriasis, eczema, and other conditions can produce similar changes, making an accurate diagnosis important before beginning treatment.
How Do You Get a Fungal Nail Infection?
Fungi thrive in warm, moist environments and can enter the nail through tiny cracks or injuries. Risk factors include:
- Athlete's foot (tinea pedis)
- Sweaty feet
- Walking barefoot in public locker rooms or pools
- Wearing tight or poorly ventilated shoes
- Nail injuries
- Increasing age
- Diabetes
- Poor circulation
- A weakened immune system
How to Help Prevent Fungal Nails
Practice Good Foot Hygiene
- Wash your feet daily with soap and water.
- Dry thoroughly, especially between the toes.
- Change socks daily or more often if they become damp.
Treatment Options
Successful treatment depends on the severity of the infection and your overall health. Options include topical antifungal medications apply for several months, oral fungal medications working from within, professional nail debridement to reduce thickness, and laser treatments as part of a comprehensive plan.
Why Does Treatment Take So Long?
Toenails grow very slowly—typically only 1 to 2 millimeters per month. Noticeable improvement may take 3 to 6 months, while complete replacement of a toenail often requires 12 to 18 months. Consistency with treatment is essential for the best results.
When Should You See a Podiatrist?
Schedule an evaluation if you notice thick or discolored nails, pain, or if nail changes occur alongside diabetes or poor circulation. Healthy nails begin with healthy feet, and our office can help develop a treatment plan tailored to your needs.
