TOE NAIL FUNGUS

Fungal nail infections are caused by many different types of fungi that live in the environment. Small cracks in your nail or the surrounding skin can allow these germs to enter your nail and cause an infection.

MORE ABOUT TOE NAIL FUNGUS

Anyone can get a fungal nail infection. Some people may be more likely than others to get a fungal nail infection, including older adults and people who have the following conditions: 2,3

  • A nail injury or foot deformity

  • Trauma

  • Diabetes

  • Weakened immune system (for example, because of cancer)

  • Venous insufficiency (poor circulation in the legs) or peripheral arterial disease (narrowed arteries reduce blood flow to the arms or legs)

  • Fungal skin infections on other parts of the body

Occasionally, a bacterial infection can occur on top of a fungal nail infection and cause serious illness. This is more common in people with diabetes or other conditions that weaken the body’s defenses against infection.
