Know about Fingernail Fungus and Ways to Treat Fingernail Fungus


Fungal infection of the nail occurs when bacteria or fungi enter the nail bed. The main cause of fingernail fungus is a broken or cracked nail plate or cuticles. It can also result from bacteria inside the body. Often characterized by cracked nail beds, fungal infection makes the nail thick and yellow. There are different fingernail fungus treatment options, but the cure takes time to show results. Before discussing fingernail fungus treatment options, let’s look at the causes and visible symptoms of fungal infection.

Causes of fingernail fungus

Fingernail fungus infection usually occurs due to overgrowth of fungi under, or in the nail. Since fungi need a warm, and moist environment to multiply, so this type of environment helps them thrive easily. Nail infections can be caused by the same fungi that are responsible for causing ringworm, athlete’s foot, or jock itch.

Nail infection can also be caused by fungi present on or in the body. It is also communicable i.e., it can spread if in case you come in contact with someone who already has a fungal infection. As stated by American Academy of Dermatology (AAD), toenails are more prone to fungal infections as compared to fingernails. This is because toes remain covered in the shoes which serves a perfect breeding ground for fungi.

Risk factors for fungal infections

Different causes can be associated with fungal nail infections, with each having its own course of treatment. Remember, although fingernail fungus is preventable, there are certain risk factors that increase the chances of developing it.

Also, if such infections are persistent in the family, chances of you getting the same automatically increases.

This is because of poor circulation and also because at later stages nail growth is slow and they are thicker than usual.
