What causes them
What causes fungal nails
Nail fungus thrives in the warm, dark, moist environment inside shoes — and it spreads easily.
Warm, Moist Conditions
Sweaty shoes and socks are ideal for fungus to grow.
Public Damp Areas
Pools, showers, and locker rooms are common sources.
Nail or Skin Injury
A small crack lets fungus get under the nail.
Athlete's Foot
A skin fungus can spread to the nails.
Weak Immunity or Diabetes
Both make fungal infections more likely.
Age
Nails grow slower and become more prone with age.
Understanding it
How to recognize nail fungus
Fungal infections usually start small and spread slowly across the nail. The earlier it is treated, the easier it clears.
Common signs include:
- Thickened toenails
- Yellow, brown, or white discoloration
- Brittle or crumbling edges
- Nails lifting from the nail bed
- A slightly foul odor
- Distorted nail shape
Why it matters
What happens if it is not treated
Nail fungus does not clear on its own and tends to spread to other nails — and sometimes the skin.
