Fungal nail infection

Fungal nail infection is called Onychomycosis. Onychomycosis is the most common nail infection, and it particularly affects the toenails in older individuals, where it can reach a prevalence of up to 40%.


Misdiagnosis is often made by doctors and dermatologists when dealing with nails affected by onycholysis, paronychia, and other conditions that share similar symptoms. In terms of etiology, various predisposing factors and clinical characteristics indicate fungal infection and the presence of fungi. Fungal infection is frequently confused with psoriasis, onycholysis, and contact dermatitis, so a definitive diagnosis requires dermoscopy of the nail plate, clinical examination, and mycological analysis.

Fungal infections are caused by dermatophytes, with the most common being Trychophyton rubrum, Trychophyton interdigitale, and Trychophytom mentagrophytes. Predisposing factors leading to fungal infection include genetics, age, diabetes, peripheral circulation disorders, a moist environment, and nail plate injuries. Fungal infections can be categorized as follows: distal subungual onychomycosis (DSO), white superficial onychomycosis (WSO), and proximal subungual onychomycosis (PSO). Each fungal infection belonging to one of these types has its clinical characteristics and is caused by a different type of fungus.

The treatment of fungal nail infection requires regular nail reduction and continuous prescription of antifungal products. Since the nail plate can protect the fungi from exposure to medications and products, the removal of fungal nail infection can be challenging, making regular nail care important.


At the Foot Center, we offer a completely painless treatment for the preparation and removal of the nail plate, with no presence of blood or damage to the surrounding tissue, allowing the patient to leave the clinic and return to daily activities. The preparation of the nail plate itself is crucial and represents the main prerequisite for the success of the treatment. Oral antifungal medications are not a suitable option due to their toxicity to the liver and kidneys.

That’s why our clinic recommends the use of exclusively natural, biological products, among which Biodeur Pythie Nail stands out. It’s a microbiological predator that feeds on pathogenic fungi and effectively treats fungal nail infections.

In rare cases, a fungal infection can be so severe that it requires surgical nail removal. Early prevention is key to a fast recovery for a nail infected with fungi. Don’t hesitate to contact your podiatrist.

Without treatment, nails can lose their color, thicken, and become deformed, while the infection can spread to the nail closer to the base of the finger. In some cases, the nail may start to hurt, and the infection can continue to spread, often leading to bacterial involvement. Fungi can spread to the surrounding skin and other parts of the body, including the genitals.

What are the most common causes of fungal nail infections, and is it related to a weakened immune system? Does a lack of certain vitamins influence their occurrence?

Fungal nail infections, also known as “onychomycosis,” are very common. They occur in as many as 14% of the general population. Fungal nail infections on the feet are more common than fungal nail infections on the hands.

The most common reason for the development of a fungal nail infection is nail injury, where small cracks in the nail or the surrounding skin can allow these microorganisms to penetrate your nail and cause an infection. Anyone can get a fungal nail infection, and besides nail injury, a weakened immune system is another key factor. The lack of vitamins, especially vitamin E, also contributes to the onset of a fungal infection. This can lead to nail cracking and even separation from the nail bed, providing an excellent entry point and breeding ground for fungi.

What are the specific factors to pay special attention to in cases of fungal nail infections?

Not every change in the nail plate necessarily indicates a fungal infection. Changes in color, separation of the nail plate from the nail bed, thickening, brittleness, and an unpleasant odor are warning signs to seek a podiatrist’s attention.

Are fungal infections perhaps related to the disease of other organs?

Fungal infection is indeed associated with diseases of other organs. Skin diseases and damage can lead to the development of fungal nail infections, as well as diabetes, vascular diseases (arteries and veins), compromised immunity due to malignancies, and foot deformities.


How long does the treatment last, and what does it involve?

The treatment of fungal infection is highly demanding and lasts from 9 to 12 months, and in some individuals, even longer. It involves primarily mechanical nail treatment, and depending on the extent of nail involvement and the severity of the infection, it may also include laser therapy, the use of Biodeur Pythie Nail products, Arkada serum, etc.

What are the treatment costs, and what factors do they depend on?

The treatment costs depend on the condition and size of the affected nail plates. The current price for mechanical abrasion ranges from 2,400 to 6,000 dinars. Laser treatment is priced at 10,200 dinars. The prices of the products range from 4,500 to 7,200 dinars.
