The causes of nail fungus infection are numerous, and a combination of the most common causes usually leads to infected nails, whether that is toenails or fingernails that have the fungal infection. Also, a common skin infection known as athlete’s foot, usually present between the toes, then invades the nail and causes the fungus problem. The hot sweaty environment found in the shoe is ideal for the fungi to grow and to spread on the toenails. Serious medical conditions such as poor circulation and diabetes can lead to worsening conditions and occasionally a secondary bacterial infection.
Most common causes of fungal nail infection:
● Nail Damage
● Poor General Health
● Smoking
● Regular use of shared washing or changing facilities
● Trauma to the nail, from poorly fitting shoes or a sports / running injury
