What Causes Nail Fungus

1. What Causes Nail Fungus? Understanding the Root of the Problem Nail fungus is a common condition that affects millions of people around the world. It usually starts as a white or yellow spot under the tip of the fingernail or toenail and can lead to thick, brittle, or discolored nails if not treated. To prevent or manage this condition effectively, it's important to understand what causes nail fungus and the risk factors involved. What Is Nail Fungus? Nail fungus, medically known as onychomycosis, is a fungal infection that affects the nail and sometimes the surrounding skin. It can affect both fingernails and toenails, though toenails are more commonly impacted. What Causes Nail Fungus? There are several contributing factors behind the development of nail fungus. Below is a breakdown of what causes nail fungus most commonly: 1. Fungal Organisms (Dermatophytes) The primary cause of nail fungus is a group of fungi called dermatophytes. These microorganisms thrive in warm, moist environments and feed on keratin, the protein that makes up your nails. 2. Yeasts and Molds In addition to dermatophytes, yeasts and non-dermatophyte molds can also infect nails, especially in people with weakened immune systems or other underlying health conditions. 3. Sweaty Feet and Tight Footwear Wearing shoes that trap moisture and don’t allow proper ventilation creates an ideal environment for fungi to grow. People who sweat a lot or wear tight shoes are more at risk. 4. Walking Barefoot in Public Areas Public showers, locker rooms, and swimming pools are common places where fungal infections can spread. Walking barefoot in these areas increases the chances of exposure.

2. 5. Nail Injuries Any small injury or crack in the nail or skin around it can give fungi an entry point. This includes damage caused by aggressive pedicures or tight-fitting shoes. 6. Weakened Immune System People with health conditions that weaken the immune system—such as diabetes, cancer, or autoimmune disorders—are more likely to develop fungal nail infections. 7. Poor Nail Hygiene Not keeping your nails clean and dry, or sharing nail grooming tools with others, can also increase the risk of fungal infections. Risk Factors to Keep in Mind Understanding what causes nail fungus also means being aware of who is most at risk. You may have a higher chance of developing it if you: ● Are over the age of 60 ● Have diabetes or circulation problems ● Work in a damp environment ● Wear artificial nails often ● Have a family history of fungal infections Conclusion Knowing what causes nail fungus can help you take the right steps to avoid it. Fungal nail infections are stubborn but often preventable. Keeping your feet clean and dry, wearing breathable footwear, and avoiding shared tools or damp public areas can go a long way in keeping your nails healthy.
