Overview: Nail fungus
It’s easy to get a fungal nail infection. If you have a fungal infection on your foot, the fungus can spread to one or more of your nails. This is quite common.
You can also catch a fungal nail infection in a warm, moist place like a pool deck or locker room. If someone else has a fungal infection and walked barefoot there, all you have to do is walk barefoot in the same area.
Having wet nails for a long time can also lead to nail fungus. Some people develop it when they wear the same pair of sweaty shoes or boots every day. Fingernails that are wet for hours at a time due to a job or hobby are also susceptible.
What you see on infected nails will vary with the type of fungus causing the infection.
Most people see some nail discoloration. The nail may have a white spot. Some nails turn yellow, brown, or green. As the infection worsens, infected nails can thicken, lift up from the finger or toe, or crumble. Some nails become thinner.
Treatment is important. It can prevent the infection from causing more damage to your nails.
If you have diabetes or a weakened immune system, treatment is especially important. After getting a fungal nail infection, people who have diabetes have an increased risk of developing sores that do not heal. Sores that do not heal can lead to a serious health problem. It’s important to see a dermatologist (or other doctor) at the first sign of a nail problem. A dermatologist can tell you whether you have a nail infection or something else.
Early diagnosis and treatment are recommended for everyone who has nail fungus. Caught early and treated, a fungal nail infection is likely to clear and you’ll regrow a healthy nail.
Treatment can also prevent the fungus from spreading to other parts of your body and to other people.
You cannot get rid of a nail infection by covering it with nail polish or artificial nails.
