Toenail Fungus: Causes and Treatment Options
- posted: Feb. 08, 2026
Toenail fungus is a common condition that can affect people of all ages, often developing slowly and becoming more noticeable over time. Discolored, thickened, or brittle nails may seem like a cosmetic issue at first, but fungal nail infections can worsen without proper treatment. At Prairie Foot and Ankle, Dr. Supreet Ghuman provides expert diagnosis and treatment for toenail fungus for patients in Elgin and Park Ridge, IL, helping restore nail health and prevent complications.
What Causes Toenail Fungus
Toenail fungus, also called onychomycosis, is caused by fungi that thrive in warm, moist environments. These organisms enter through small cracks in the nail or surrounding skin. Common risk factors include wearing tight or non-breathable footwear, prolonged exposure to damp conditions, walking barefoot in communal areas such as locker rooms or pools, and having a weakened immune system.
Certain medical conditions can also increase risk. Diabetes, poor circulation, and nail injuries make it easier for fungal infections to take hold and harder for the body to fight them off. Once established, the infection can spread to other nails if left untreated.
Common Signs and Symptoms
Toenail fungus often begins subtly and progresses gradually. Early signs may include white or yellow discoloration at the tip or sides of the nail. As the infection advances, the nail may thicken, become brittle or crumbly, develop ridges, or lift from the nail bed. Some patients experience discomfort or pressure in shoes, particularly when the nail becomes significantly thickened.
Because fungal nail infections do not usually resolve on their own, persistent changes in nail appearance should be evaluated by a podiatrist.
How Toenail Fungus Is Diagnosed
Accurate diagnosis is essential before starting treatment. Dr. Ghuman examines the affected nail and may take a small sample to confirm the presence of fungus and rule out other nail disorders. Identifying the specific cause helps guide treatment decisions and improves the likelihood of successful results.
Treatment Options for Toenail Fungus
Treatment depends on the severity of the infection, the number of nails involved, and the patient’s overall health. Mild cases may respond to prescription topical medications applied directly to the nail. More advanced infections often require oral antifungal medication or in-office treatments designed to target the fungus beneath the nail surface.
Because toenails grow slowly, treatment requires patience and consistency. Even after the infection is cleared, it may take several months for a healthy nail to fully grow in. Dr. Ghuman develops personalized treatment plans to maximize effectiveness while minimizing the risk of recurrence.
Preventing Future Infections
Preventing toenail fungus involves good foot hygiene and protective habits. Keeping feet clean and dry, changing socks regularly, wearing properly fitting shoes, and avoiding barefoot walking in public areas can reduce exposure. Early treatment of athlete’s foot and regular nail care also help prevent fungal spread to the toenails.
If you are concerned about nail discoloration or thickening, professional care can help prevent the condition from worsening. To schedule an evaluation for toenail fungus with Dr. Supreet Ghuman at Prairie Foot and Ankle in Elgin or Park Ridge, IL, call (224) 227-6973 today.
