What is Athlete's Foot?
Athlete’s foot is a common skin condition that is caused by fungi. It is fairly prevalent and according to latest estimates, about 3-15% individuals develop athlete’s foot at some point in their life. Men and older individuals are mostly affected.
The symptoms include itchy skin that cracks and flakes, especially between toes or sides/ soles of feet. In poorly managed cases, it may spread to nails to cause fungal nail infection. You can get athlete’s foot is you walk barefoot in public places with moist/ warm environment such as showers, changing rooms, locker rooms, swimming pool decks, etc. In addition, you can also catch infection by touching/ sharing articles from an infected person.
Symptoms of athlete’s foot can be managed by anti-fungal creams, ointments, or powder. In some cases, your GP may suggest steroid cream or other medicines if there are signs of bacterial infection.
Proven Preventive Regimen
Although the recurrence rate of athlete’s foot infection is fairly high, you can follow these tips to prevent re-infection
Keep Your Feet Clean & Dry
Fungal agents prefer moist and damp environment. Therefore, it is highly recommended to:
- Dab your feet dry after bathing or washing your feet. Give special emphasis to the area between toes and creases
Maintain caution with shoes
- Avoid wearing shoes when you are at home or resting to keep your skin exposed to fresh air
- Avoid wearing the same pair of shoes for more than two days in a row
- Avoid shoes that makes your feet hot and sweaty (especially in hot humid weather) such as shoes made from plastic or rubber
- In hot humid weather, wear flip flops or open sandals instead of covered shoes that makes your feet hot and sweat
Maintain Optimal Hygiene
- Keep a separate towel for your feet and make sure to wash it at periodic intervals
- Be sure to change your socks every day and always choose a breathable fabric for your sock (such as cotton)
- Avoid walking barefoot in exposed moist places such as showers, changing rooms etc.
- Never share your towel or personal articles (such as shoes, socks) with other people
- If you have an active lesion, or infection, avoid scratching or touching it as it may spread the infection to other parts of the body

If your symptoms don’t improve with topical formulations, you should seek help from a healthcare professional who may advise oral antifungals (such as Fluconazole or Itraconazole) or prescription grade topical antifungals. The prescription grade antifungals are usually prescribed for 3-6 weeks. If your doctor suspects a bacterial infection along with fungal infection, you may be advised a course of Sulconazole or Ciclopirox and for 4 weeks.

- Your feet are in severe pain or discomfort
- If your symptoms are not improving with over-the counter treatment options
- If you have a history of diabetes as people with diabetes develop more severe infection
- If you have compromised immune system (such as if you are on chemotherapy, have received a transplant or are on immunosuppressant medications)
