Toenail fungus rarely starts out of nowhere. In most cases the fungi get to the nail from the skin of the foot, from a wet floor or from a shared towel, and then settle in because the conditions suit them. You can change many of those conditions yourself, mostly with small daily habits. It also helps to know the early signs, so a problem gets looked at before it spreads to several nails.
Why fungus likes feet
Fungi that affect nails thrive in warm, damp and dark places. A foot inside a closed shoe for many hours is exactly that kind of place. Sweat softens the skin, small cracks appear between the toes, and the fungi find an easy way in.
Nail fungus often begins on the skin. Athlete's foot, with itching, peeling or cracks between the toes, can spread to the nail if it is left alone. Once the fungus is inside the nail plate, it is much harder to deal with than on the skin.
Some people are more at risk than others:
- people whose feet sweat a lot;
- people with diabetes or poor circulation in the legs;
- older people, whose nails grow more slowly and are harder to care for;
- anyone with a nail that has been injured, for example by tight shoes or a heavy object;
- people who often use shared showers, pools, saunas or gyms.
Everyday habits
No single product prevents it. What works is a handful of plain habits:
- After a shower, dry between the toes too. That is where moisture stays longest.
- Put on clean socks every day, and change them during the day if your feet sweat. Pick socks that let moisture out.
- If you can, do not wear the same pair two days in a row, so the shoes dry out completely.
- Wear shoes that breathe and leave room for your toes. Pressure on the nail can damage it, and a damaged nail is easier for fungi to enter.
- Trim your nails straight across, keep them short and use your own clean tools.
Public places and shared things
Pools, saunas, gym changing rooms and hotel showers are places where many bare feet walk on the same wet floor. Your own flip-flops there go a long way.
At home, the same logic applies. Towels, socks, slippers and nail clippers should be personal. If someone in the family already has athlete's foot or nail fungus, it is worth being especially careful: wash their towels and socks separately and do not share nail tools.
The same goes for any place where your nails are cared for. Instruments used on many clients must be properly cleaned and sterilised between them. You can simply ask how they do it.
Early signs not to ignore
Nail fungus usually develops slowly, and at the beginning it is easy to miss. Look out for:
- a white or yellowish spot or streak on the nail;
- a nail that becomes thicker, duller or rougher than the others;
- a nail edge that crumbles or breaks easily;
- a nail that starts to lift away from the skin underneath.
These changes do not always mean fungus. A nail can change colour or thicken after an injury, with psoriasis or for other reasons. So guessing and buying whatever the pharmacy shelf offers is a poor plan. A doctor can confirm the cause, often with a simple test of nail material, and choose the right treatment.
When to see a specialist
It is worth booking a visit if the change on the nail does not go away, spreads to other nails, hurts in shoes, or if the skin around the nail is red and sore. For people with diabetes or circulation problems, any change on the feet is a reason to get help early.
Treatment of a fungal infection is prescribed by a doctor. A podiatrist helps in a different way: by carefully thinning and cleaning the affected nail, which makes it more comfortable and helps the treatment the doctor has chosen to reach where it needs to. At PODOKOM in Rzeszów we clean fungus-affected nails and provide care alongside the doctor's recommendations, using instruments sterilised in an autoclave. We also work with dermatologists when a case needs a doctor's opinion.
