Health Information For Teens
Athlete’s foot is a type of fungal skin infection. Fungi (the plural of fungus) are microscopic plant-like organisms that thrive in damp, warm environments. They’re usually not dangerous, but sometimes can cause disease. When they infect the skin, they cause mild but annoying rashes. Fungal skin infections are also known as tinea infections.
When fungus grows on the feet, it is called athlete’s foot (or tinea pedis). It got this name because it affects people whose feet tend to be damp and sweaty, which is often the case with athletes. But anyone can get this infection.
Other fungal skin infections include jock itch and ringworm (despite its name, ringworm is not a worm).
These infections are caused by several types of mold-like fungi called dermatophytes (pronounced: der-MAH-tuh-fites) that live on the dead tissues of your skin, hair, and nails.
Athlete’s foot usually causes redness, flakiness, peeling, or cracking of the skin on the feet. It may itch, sting, or burn, or simply feel uncomfortable.
It’s usually on the soles of the feet, the areas between the toes, and sometimes the toenails. When the toenails are involved they become thick, white or yellowish, and brittle.
Athlete’s foot is caused by fungi that normally live on the skin, hair, and nails called dermatophytes. When the environment they live in gets warm and moist, they grow out of control and start to cause symptoms.
Yes. It spreads in damp environments, such as public showers or pool areas. It can also spread to other areas of the body if a person touches the affected foot and then touches other body parts, such as the hands.
Waking around barefoot in warm wet places like locker rooms or public pools can expose the feet to fungi that thrive in those environments. Sweaty shoes and socks add to the dampness and can make the infection worse. Sharing towels, sheets, clothing, or shoes with someone who has athlete’s foot also can spread the infection.
A doctor can often diagnose athlete’s foot just by looking at it and asking questions about the symptoms and the person’s lifestyle. Sometimes the doctor will scrape off a small sample of the flaky infected skin to look at under a microscope or to test in a laboratory.
Over-the-counter (OTC) antifungal creams, sprays, or powders may solve the problem if it is mild. More serious infections may need prescription medicine, either topical (applied to skin) or in pill form.
Whatever you use, continue treatment for as long as recommended, even if the rash seems to be getting better. If not, the infection can come back. Some people regularly use medicated foot powders and sprays to prevent this from happening.
Most mild cases of athlete’s foot clear up within 2 weeks. But treatment can go for several weeks or longer if the infection is more serious or affects the toenails.
Athlete’s foot often can be prevented. To avoid it:
Ringworm isn’t a worm at all – it’s the name for a type of fungal skin infection. The good news is that ringworm is easy to treat.
Puberty causes all kinds of changes in your body – and some may not make you feel very desirable. Read this article for information on dealing with greasy hair, perspiration, and body hair.
Sometimes it may seem like your skin is impossible to manage, especially when you find a huge zit on your nose or a cold sore at the corner of your mouth. Here are ways to prevent and treat common skin problems.
Jock itch is a pretty common fungal infection of the groin and upper thighs. It is generally easy to treat – and avoid – by following a few simple steps.
Our skin protects the network of tissues, muscles, bones, nerves, blood vessels, and everything else inside our bodies. Hair and nails are actually modified types of skin.
Impetigo is a skin infection caused by fairly common bacteria. Read this article to learn how to recognize it and what to do about it.
A toenail is ingrown when it begins to break through and grow into the soft skin of the toe. Find out more about ingrown toenails.
Germs are tiny organisms that can cause disease – and they’re so small that they can creep into your system without you noticing. Find out how to protect yourself.
