Cause of Nail Fungus

Causes of Nail Fungus


Nail fungal infections are one of the most common skin conditions. It is also known as onychomycosis. Some people are at a high risk of a fungal infection than others. Such infections account for half of the nail disorders. Fungus is usually present in our body but should not exceed to undesired levels. Both fingernails and toenails are prone to fungal infections. However, toenails are more affected than fingernails. Let us learn about common causes, symptoms and prevention of nail fungal infections.


Fungal infections affect our nails adversely. Foot fungus symptoms include:

  • Thick nails
  • Yellow color
  • Breakage of nails
  • Disfigured shape
  • Debris under the nail surface
  • Bad smell and pain
  • White or yellow dots

The fungi usually infect a nail through cuts and cracks around the nail skin. The area beneath the nail surface is suitable for fungal growth. That is why nail fungus is common in toenails as they are in a closed space. If not treated, the infection can spread to other areas of skin or nails.


Fungi, yeasts and molds cause most of the nail infections. All of them result in similar symptoms.

Most common causes of nail fungus are dermatophytes. Other than that yeast Candida cause most of the fingernail infections. Yeasts cause approximately 8% of nail infections. On the other hand, molds cause just 2% of them. Fungi cells remain active in our body for a long time. Hence, there is always a risk of recurrence.


The risk of infection increases according to these factors:

Climate: Fungal infections are common in hot and humid places.

Age: The risk increases with age. Therefore, it is common in older people. Fungal infections are rare in children below 6 years.

Health: The risk increases in case of these health conditions

  • Athlete’s foot
  • Nail Surgery
  • Nail Injury
  • Other nail infections
  • Diabetes
  • Poor blood circulation
  • Chemotherapy
  • Weak Immune System

Lifestyle: These lifestyle factors also affect your nail health

  • Wet feet and hands
  • Smoking
  • Spending excess time in water
  • Not wearing shoes in public showers & locker rooms
  • Tight shoes
  • Sweaty feet
  • Wearing gloves for a long time
  • Skin to skin contact with anyone having a fungal infection
  • Sharing towels or nail clippers

Infected nails break and split easily. Sometimes, a white dot appears on the nail which gets bigger with time. Therefore, it is also known as a white toenail fungus. If not treated in time, there is a risk of spreading the infection to other body parts.


Treatment of nail fungus depends upon the cause and intensity of infection. Topical and oral medications are used to get rid of nail fungus. Oral medications are aggressive and have a risk of side effects. On the contrary, topical treatments are easy to apply and have no side effects.
