Nail fungus begins as a white or yellow spot under the tip of your fingernail or toenail. As the infection spreads it goes deeper nail fungus is painful and change the color of your nail and cause it to thicken. If it is not treated in due time, it could spread to other nails. Toenail fungus spreads through the cracks in your nails or cuts in your skin. The toes tend to be warm and damp creating ideal space for the fungus to grow. There are different types of fungi affecting different parts of the nail. The infected nail may get separated from the nail bed and you may experience pain and foul odor.

What are the causes?
Along with bacteria, the fungus is also present in your nail. Fungal infections normally take some time to grow and it is the warm, moist environment that causes them to grow. Medically this is known as Onychomycosis. The nail fungal infection is caused by dermatophyte fungi.

Factors that can lead to development of the fungus
Factors can be many; some of the common ones are listed below:

• As the age increases due to the slow growth of nails and reduced blood flow to the nails it could lead to the development of fungus.
• If a person perspires heavily and adequate care to keep the palm and feet dry are not taken then it could lead to nail fungus.

It is observed that toenails are more affected by fungus than the fingernail. The reason behind this is as follows:

• Toenails are mostly in dark and warm condition due to the shoes, creating an ideal atmosphere for the fungus to breed.
• Toes also have less blood flow as compared to the fingers, so they cannot defend themselves from the attack of fungus.

What are the symptoms?
Following are the symptoms of nail fungus:

• Thickened nails
• Brittle, crumbly or ragged nails
• Distorted shape of nails
• Dull nails
• Dark color spot below the nails due to formation of debris

The doctor examines the nail and may scrape the nail and debris and send it to the lab for examination to detect the cause of fungal infection and the type of fungus affecting it.
