Athlete's foot, also known as tinea pedis, is a common fungal infection of the feet that can cause itching, burning, and cracking of the skin. While it is often considered a minor annoyance, it can become a serious problem if not treated properly.
Athlete's foot can range from mild to severe. In mild cases, the infection may cause redness, itching, and peeling of the skin, usually between the toes. In more severe cases, the infection may spread to the soles of the feet, causing blisters and cracking of the skin. In extreme cases, the infection may spread to other parts of the body, such as the scalp, groin, and toenails.
Left untreated, athlete's foot can lead to a number of complications. For example, the infection can spread to other parts of the body, such as the hands, resulting in a more widespread infection. The infection can also cause bacterial infections, such as cellulitis, which can be very serious and require medical attention. In addition, the infection can cause a secondary infection, known as a secondary bacterial infection, which can be even more serious.
People with weakened immune systems, such as those living with HIV/AIDS or undergoing chemotherapy, are at an increased risk for developing more severe forms of athlete's foot. In addition, people with diabetes are at increased risk for developing complications from athlete's foot due to impaired circulation in their feet.
The best way to prevent athlete's foot is to keep feet clean and dry, wear clean socks and shoes, and avoid using public showers and locker rooms. If an infection does occur, it is important to seek medical attention as soon as possible. Treatment typically involves topical antifungal medications, which can help clear up the infection and prevent it from spreading. In severe cases, oral antifungal medications may be prescribed.
