Does nail fungus go away on its own?

Usually not. Without treatment, it tends to spread further, which is why patience and consistency are important.

Is nail fungus contagious?

Yes, the pathogens can be transmitted via damp floors or shared items. Good foot hygiene reduces the risk.

How long does treatment take?

Since the nail grows slowly, it can take many months until a healthy nail has grown back.

Nail Fungus — Causes, Assessment & the Right Specialty

Nail fungus presents as thickened, discolored, and brittle nails, most commonly on the toes. It usually develops slowly and typically does not disappear on its own. However, with patience and consistent treatment, the appearance of the nail can usually be improved.

Possible causes

Dermatophytes

The infection is usually caused by so-called dermatophytes. They feed on the nail material and cause the nail to thicken.

Moist, warm environment

Sweaty feet, tight footwear, and damp floors provide good conditions for fungi.

Pre-existing nail damage

Minor injuries, pressure points, or existing athlete's foot make it easier for pathogens to penetrate.

Contributing factors

Circulatory problems, diabetes, or a weakened immune system can promote nail fungus.

Typical steps at the doctor's office

1Your doctor will assess the appearance of the nail and distinguish the fungus from other nail changes.
2To confirm the diagnosis, a sample of the nail material may be taken and examined in a laboratory.
3Treatment depends on the extent and which nails are affected, and usually requires patience and consistency over an extended period.

What you can do yourself

Wash your feet daily and dry them thoroughly afterwards, especially between the toes.
Wear breathable shoes and socks made of natural fibers, and change your shoes regularly.
Wear shower shoes in swimming pools and communal showers, and do not share towels.
When trimming your nails, use your own clean tools and do not share them with others.

When a doctor's visit makes sense

An examination is advisable if the nail becomes increasingly discolored or thickened, if multiple nails are affected, or if symptoms occur. If you have diabetes or circulatory problems, changes to the toenails should be professionally assessed early on.
