Nail Infection

A nail infection, also known as onychomycosis, is a common condition that begins as a white or yellow spot under the tip of your fingernail or toenail. As the fungal infection goes deeper, nail infection may cause your nail to discolor, thicken and crumble at the edge. It can affect several nails but usually not all of them.

Causes[edit | edit source]

Nail infections are caused by various fungal organisms (fungi). The most common cause is a type of fungus called dermatophyte. Yeast and molds also can cause nail infections.

Symptoms[edit | edit source]

Nail infection can affect part of the nail, the entire nail, or several nails. Common signs of a nail infection include:

  • Thickened nails
  • Whitish to yellow-brown discoloration
  • Brittle, crumbly or ragged nails
  • Distorted in shape or separated
  • A dark color, caused by debris building up under your nail
  • Smelling slightly foul

Treatment[edit | edit source]

Treatment of nail infection might involve pharmacological therapy, surgical treatment, or a combination of both. Oral antifungal drugs, topical medicated nail polish or cream, and surgical nail removal are common treatments.

Prevention[edit | edit source]

Prevention of nail infection involves proper hygiene and regular inspection of the feet and toes. It is also recommended to keep the nails short, and avoid walking barefoot in public places.
