What is a Fungal Nail Infection? A fungal nail infection, referred to in medical terms as onychomycosis, occurs when fungi (a kind of microorganism) infect your nails. You may first notice the infection as a white or yellow spot under the tip of your nail. Symptoms of a fungal infection may include brittleness, discoloration, thickening and crumbling of the nail, as well as debris under the nail itself. In some cases, the nail can detach from the nail bed. Approximately 50 percent of all nail disorders are fungal infections. There are many contributing causes, including physical damage to the nail, a weakened immune system due to conditions such as diabetes and cancer, and overexposure to water or detergents.

How to Manage Fungal Nail Infections Treatment of a fungal nail infection can take a while to complete, and is best begun at the early stages of infection, before it has spread deeper into the nail. See your doctor right away if you see any change in your nail or feel swelling or pain. Fungal infections can be cured with the most recent therapies. Your doctor will choose the best treatment for you based on the type of infection and the amount of the nail involved. Treatment can range from 3 to 18 months to completely clear up the fungal infection. It’s very important to follow your doctor’s recommendations and the instructions found in the package insert of the prescribed product.

What to Expect The appearance of your nail will improve as your nail is slowly replaced by a healthy nail. It is important to keep in mind that this process can take up to 6 months for fingernails and 9-12 months for toenails. Even in successful cases, relapse is common. Therefore, your doctor may want you to return for periodic visits to evaluate the progress and outcome of your treatment.
