Foot Fungus: Causes, Prevention and Effective Treatment

Foot fungus, medically known as tinea pedis, is a common fungal infection that affects the skin of the foot, especially between the toes. It causes itching, redness, and flaking skin that can sometimes be painful. Although it is generally not serious, the discomfort can be considerable and the infection can sometimes recur stubbornly.

Causes and Characteristics of Foot Fungus

Athlete’s foot occurs when the types of fungi that naturally live on our skin, such as Trichophyton, Epidermophyton, and Microsporum, grow excessively. These fungi thrive in warm, humid environments such as sports shoes, swimming pools, and locker rooms.

Various clinical features to recognize athlete’s foot:

1. Itching and burning sensation: These symptoms are often the first signs of an infection. The itch can range from mild to severe and usually gets worse as the infection progresses.
2. Red and flaky skin: The skin between the toes or on the soles of the feet can become red and start to flake. Sometimes you also see dry, flaky spots on the bottom of the foot.
3. The presence of edge flakes. These are small, loose pieces of skin on the edges of the infected areas that are often seen along the edges of the feet and between the toes. These edge flakes are an indication that the fungus is actively affecting the top layers of the skin and is spreading. They can easily come loose when the skin is touched or rubbed, which contributes to the spread of the fungus to other parts of the body or to other people.
4. Unpleasant odor: A strong, unpleasant odor is another common characteristic of foot fungus.
5. Discoloration and thickening of nails: If the fungus spreads to the toenails, they may become yellow or brown and thicker than usual.

Sometimes there are also blisters present, this form is called tinea pedis bullosa. It is a less common presentation of athlete’s foot, but it can be very annoying.

Blisters on foot fungus

• Usually occur between the toes, but can also occur on other parts of the foot.
• Are often small and filled with clear fluid, but can also become larger and filled with pus.
• Can itch, hurt or feel burning.
• Cracks sometimes open, which can lead to secondary bacterial infections.

Factors that increase the risk of blister formation:

• Athlete’s foot: A type of foot fungus that often causes blisters.
• Weakened immune system: People with diabetes, HIV/AIDS, or other conditions that weaken the immune system are at a higher risk of blister formation.
• Humid Environments: Athlete’s foot thrives in warm, humid environments, such as sports shoes, swimming pools, and locker rooms.

Treatment and Prevention

The treatment of foot fungus focuses on removing the fungus and preventing reinfection. Here are some effective methods:

1. Anti-fungal creams and sprays: Over-the-counter antifungal products, such as clotrimazole, terbinafine, or miconazole, are effective in most cases. These agents should be applied one to two times a day, depending on the specific product. It is important to continue the treatment for the full recommended duration, often 2 to 4 weeks, even if the symptoms disappear earlier.
2. Good Foot Hygiene: Keep your feet dry and clean. Thoroughly dry your feet, especially between the toes, after showering or swimming. Change socks regularly, especially if your feet sweat quickly.
3. Breathable shoes: Wear shoes that allow air to pass through and avoid wearing the same shoes two days in a row to give them a chance to dry out.
4. Anti-fungal powders: These can be sprinkled in shoes and socks to keep the feet dry and inhibit the growth of fungus.
5. Washing of socks: To effectively kill fungi, wash socks at a temperature of at least 60 degrees Celsius. This ensures the elimination of fungal spores.

In severe or persistent cases, it may be necessary to use prescription oral antifungal agents. These are usually prescribed by a dermatologist.

Preventing athlete’s foot by wearing slippers in public showers and changing rooms is essential. Regular inspection of the feet helps to recognize the signs of athlete’s foot early and treat it quickly.

Natural Ingredients

Natural remedies are less researched. Often it is also asked during the consultation which alternative means I can use in addition. These can be used as supplementary treatments, but do not replace proven antifungal therapies.

Below are some of these ingredients, with their respective benefits and potential disadvantages:

1. Tea Tree olie
   • Benefits: Tea tree oil is known for its powerful antifungal and antibacterial properties. It may be effective in reducing the symptoms of athlete’s foot, such as itching and scaling.
   • Disadvantages: Some people may develop allergic reactions to tea tree oil, especially when used undiluted. It’s important to apply this ingredient cautiously due to potential allergic reactions.
2. Kokosolie
   • Benefits: Coconut oil contains medium-chain triglycerides, such as lauric acid, which possess antifungal activities. Regular use can help reduce the fungus.
   • Disadvantages: Coconut oil is comedogenic, which means it can clog pores if used elsewhere on the skin. For the feet, this is usually less of a problem.
3. Appelcider azijn
   • Benefits: Apple cider vinegar is acidic and can help alter the skin’s pH balance, creating a less hospitable environment for fungi.
   • Disadvantages: The acid in apple cider vinegar can be irritating, especially on damaged or very sensitive skin. It should always be used diluted to prevent skin irritation.
4. Oregano olie
   • Benefits: Oregano oil contains thymol and carvacrol, two compounds with strong antifungal properties.
   • Disadvantages: Just like tea tree oil, oregano oil can be irritating or cause allergic reactions. It needs to be diluted before being applied to the skin.
5. Knoflook
   • Benefits: Garlic contains ajoene, a natural antifungal compound that can be effective against foot fungus.
   • Disadvantages: Garlic can cause irritation and even chemical burns on the skin when in direct contact. Use with caution and consider using in a diluted form.

While natural ingredients can provide adjunctive treatment for foot fungus, it’s essential to be mindful of their potentially irritating effects and possible allergic reactions. Test on a small patch of skin: Before using a natural remedy on the entire affected area, test it on a small patch of skin to check for irritation or allergic reactions. Dilution: Always use natural remedies, such as tea tree oil and oregano oil, diluted with a carrier oil like coconut oil or olive oil.

These ingredients are generally less potent than pharmaceutical antifungal agents, such as miconazole, ketoconazole cream or Itraconazole, Terbinafine and Diflucan tablets.
