Nail fungus: recognise, treat, prevent

Nail fungus (onychomycosis) is very common – especially on the toenails. It is usually not dangerous, but stubborn: without treatment it spreads and can pass to other nails or people. The sooner you act, the better.

How do I recognise nail fungus?

• whitish, yellowish or brownish discolouration, often starting at the edge
• thickened, brittle or crumbly nail
• the nail partly lifts from the nail bed

Not every discolouration is fungus – pressure or injuries can also change nails. A dermatologist can confirm the diagnosis.

How is it transmitted?

Fungi love warmth and moisture. Common places of infection are swimming pools, saunas, changing rooms and hotel rooms. Nail fungus is promoted by:

• untreated athlete’s foot
• tight, non-breathable shoes and heavy sweating
• circulation problems, diabetes or a weakened immune system
• small injuries to the nail

Treatment: patience pays off

The actual antifungal therapy – usually a special nail lacquer, in severe cases also tablets – is determined by a doctor. Because a toenail only grows about one millimetre a month, it often takes a year or longer until the nail has grown back completely healthy. Sticking with it is key.

How we support therapy

• Removing and thinning: we gently file down thickened, affected parts of the nail. This helps the active ingredient penetrate and relieves pressure.
• Advice and care: we show you how to avoid reinfection and accompany your medical treatment.
• Nail prosthetics: if the nail is damaged or partly lost, we can restore it with an artificial nail – for a neat appearance and protection while the healthy nail grows back.

Prevention

• dry feet thoroughly after washing, including between the toes
• wash socks at 60 °C or more and change them daily
• wear flip-flops in pools, saunas and hotels
• let shoes air out and disinfect them if needed
• use your own towels and nail tools
• treat athlete’s foot early
