Causes of Toenail Fungus Infections

Since nearly everyone comes into contact with the micro-organisms that cause fungal infections of the toenails, why do some people get it and others don't? Nail fungus is more common among older adults. Reasons for this may include diminished blood circulation, more years of exposure to fungi and nails which grow more slowly, making them more prone to infection. Researchers also believe that there are hereditary factors involved.

No one can keep from aging or change their genetic predisposition, but most of the contributing causes of toenail fungus are within your control. These risk factors include:

- Wearing footwear for a long period of time
- Poor foot hygiene
- Wearing shoes or socks that retain moisture
- Walking barefoot in places likes public showers and locker rooms
- Minor cuts on your feet or damaged toenails
- Heavy foot perspiration
- Diabetes, HIV or circulatory problems which hinder the immune system
