Tinea pedis - Symptoms, Causes, and Treatment

Tinea pedis, commonly known as athlete’s foot, is a contagious fungal infection that affects the skin on the feet. It is caused by various types of fungi, most commonly the Trichophyton genus. Athlete’s foot can affect anyone, but it is more common in individuals who frequently expose their feet to warm and moist environments, such as athletes.

The main culprit behind athlete’s foot is excessive sweating of the feet, as moisture provides an ideal breeding ground for the fungus. The infection is easily spread through contact with infected surfaces, such as floors, socks, and shoes. Wearing tight-fitting shoes, not drying the feet properly, or walking barefoot in public places can increase the risk of developing athlete’s foot.

Individuals with athlete’s foot often experience symptoms such as itching, burning, and redness on the affected areas, especially between the toes. The skin may become dry, scaly, and cracked, and blisters may form. If left untreated, the infection can spread to other parts of the foot, including the toenails.

Treatment for athlete’s foot usually involves the use of over-the-counter antifungal creams or powders. These products help kill the fungus and relieve the symptoms. It is important to continue using the medication for the recommended duration, even if the symptoms improve, to ensure complete eradication of the infection. In severe cases or when the infection does not respond to over-the-counter products, a healthcare professional may prescribe stronger antifungal medications.

Preventing athlete’s foot is possible by practicing good foot hygiene. This includes keeping the feet clean and dry, wearing moisture-wicking socks and breathable shoes, and changing socks frequently, especially after physical activities. It is also advisable to avoid walking barefoot in public areas and to use antifungal powders or sprays in shoes and on feet to help prevent infection.
