A thorough examination from a healthcare provider is recommended. They will usually take a sample of the infected nail for analysis. Depending upon the severity of the infection, a more in-depth analysis may be ordered.
The main medical treatments are antifungal drugs. These drugs may be taken orally or applied directly to the nail.
In vitro (lab-based) and animal studies have tested supplements on other types of fungal infections, but no research has tested if these supplements treat nail fungus specifically in humans. Compounds like monolaurin (which is derived from coconut oil), or certain flavonoids (e.g., liquiritigenin) may have general antifungal effects. Overall, more human evidence is needed before any supplement can be recommended for treating nail fungus.
Currently, there is no research connecting diet and nail fungus.
Treatments that do not use antifungal drugs are limited. However, laser therapy (a treatment in which the nail is exposed to a powerful light source) has the potential as an alternative treatment for nail fungus.
Fungal infections can occur anywhere on the body and typically develop in dark, warm and moist environments. For instance, if one is constantly wearing shoes that often get wet, this may increase the risk of developing nail fungus.
