Toenail fungus is also called onychomycosis or tinea unguium. This is a fungal infection that affects the nails. This may start as a discoloration of the nail tip and often it is yellow. The nail then becomes darker, thick, and hard to trim. It may crumble at the edges. Sometimes the nail may be painful particularly on the tips of nails. A foul smell may also come from the infected nail. Infected nails may separate from the nail bed. This condition is called onycholysis, and it is usually painless.
7What are the causes of toenail fungal infections?
There are three types of fungi that can cause toenail fungal infections: molds, yeasts, and dermatophytes. A nail infection caused by yeasts is often white while toenail infections caused by molds are brown. When the infection is caused by a dermatophyte, the nail is often yellow. These different causes require various treatments. That’s why it’s crucial to know the microorganism that caused the infection to determine the appropriate nail fungus treatment.
