A fungal toenail infection, also known as onychomycosis, can be unsightly and uncomfortable. Infected nails often become thickened, brittle, crumbly, and discolored with white, yellow, or brown patches. The affected nails may also lift from the nail bed and emit a foul odor.

Fungal toenail infections are contagious and are caused by a fungus getting in, on, or under the toenails. Fungi thrive in moist, warm environments like public swimming pools, locker rooms, and showers, and many people contract fungal nail infections from walking barefoot in these environments. The fungus can also spread from person to person. For this reason, it is best to avoid sharing personal items like shoes, socks, and towels with an infected individual.

Certain factors can make one more likely to contract toenail fungus. People who have diabetes, poor circulation, or weakened immune system, are over the age of 65, wear artificial nails, have a toenail injury or damaged skin around their toenails, wear closed-toe shoes, and expose their feet to moisture for extended periods of time are at an increased risk of onychomycosis.

Treatment options for toenail fungus include oral medications and topical solutions such as medicated nail polishes and creams. Treatment can take several months to be effective, so it is recommended that you see a chiropodist as soon as you notice the symptoms of toenail fungus. For more information about this condition, please consult with a chiropodist.
