Nail fungus is a condition that attacks nail beds and nail plates. Fungus will attach itself to skin until it finds an opening, which in most cases is the toenail area of the foot. Nail fungus may attack one or more nails at a time and cause discoloration of the nail. Though discoloration is one of its primary symptoms, it can also cause the infected nail to become hardened, thus making it more difficult to treat. Nail fungus can go undetected by the immune system for years if left untreated.
Poor Circulation
Poor circulation is a contributing factor to nail fungus. Restriction in blood flow can cause the nail to lose valuable nutrition, which makes it weak and susceptible to attract nail fungus. According to the American Diabetes Association, disorders like diabetes may cause poor blood circulation to the legs and feet. The condition causes blood vessels to become hard, making it much more difficult for blood to flow properly. Poor blood circulation also affects the body's ability to properly fight off nail infections. Once the fungi has touched or penetrated the nail bed, it will thrive in weak areas of the nail.
Skin Moisture
Individuals who are regularly around water, such as swimming pools, are more susceptible to getting nail fungus infections, according to MedlinePlus. Wearing closed-in shoes that trap water or sweat around the foot area may allow foot fungus to penetrate the skin, especially if there is an opening in the skin on or around the nail bed.
Unsanitary Nail Salon Practices
It is also possible to develop nail fungus through manicure equipment that has not been thoroughly cleaned. Nail salons may practice unsanitary practices such as using the same tools on each customer. Unsanitary practices include not properly cleaning pedicure basins and using the same nail care tools on everyone. Nail technicians who do not wash their hands between customers may also carry microscopic fungi that can be passed along to others as well. MayoClinic.com advises individuals to take their own nail care tools to the salon.
