Toenail Fungus or Onychomycosis usually develops on the front part of the nail or its edges. It does not usually start at the base of the nail. In some cases, it can cause white patches that form on the surface of the nail. It may stay as dots, or it could spread out. This case is called White Superficial Onychomycosis.
This condition is caused by dermatophytes, which is a type of fungi that infects the skin. Sometimes they are caused by yeast or mold. Yeast infection commonly affects fingernails. Many people who have nail fungus also have athlete’s foot. The same fungus causes both onychomycosis and athlete’s foot. Because of this, Athlete’s foot can cause nail fungus and vice versa.
