Nail fungus on the big toe: causes and treatment, ointment

Fungal infection of the nails belongs to a large family of ringworms caused by fungal parasites of the dermatophyte genus (Tinea Mentagrophytes, Epidermophyton floccosum, Candida fungi and mold mycelium).

It is their active detrimental effect on the nail plate that leads to the pathological destruction of their structure.

The causes of the fungus of the big toe

Causes of nail fungus on the big toe can be very diverse, but the main one is the huge viability of the fungal parasite. He is able to instantly penetrate, adapt and develop in conditions favorable to him.

Penetrate into the microscopic cracks of corns and calluses, arising mainly in the zone of the big toe. Especially if the shoes "do not breathe" or do not fit the size of the feet.

But even this fact does not always indicate the mandatory development of a fungal infection. A healthy immunity itself can cope with the infection. At risk are people with the presence of various background pathologies:

  • endocrine diseases (in particular diabetes);
  • recurrent scaly lichen (psoriasis);
  • varicose vascular disease;
  • AIDS indicator pathologies;
  • pathologies of metabolic processes;
  • eczema and dermatitis;
  • skin infections.

An additional source of infection, which can be attributed to the main reason - contact with the carrier of the infection or with personal objects of his use. The most likely causes include contact with patients in sports centers, swimming pools or public baths.

The transfer of the fungus can occur when trying on other people's clothes and shoes, in beauty parlors, where tools are not properly processed, etc.

Enhances the likelihood of fungus manifestation:

  • neglect of personal hygiene;
  • synthetic underwear and substandard shoes;
  • excessive obesity and addiction to alcohol.

The elderly are most vulnerable to fungal disease. With age, physiological changes occur in the structure of the nail plates, they thicken, blood circulation is disturbed, the protective acid balance changes, which creates favorable conditions for the penetration and development of the disease.

Stages of development of nail fungus on the legs

Stages of development of nail fungus on the legs The subungual environment is the most optimal place for the growth of the fungal mycelium, since it contains a large amount of nutrients. As a result of the action of microorganisms on the tissue structure of the subungual bed, a certain enzyme is released that destroys the tissue itself and durable fibrillar plate proteins.

Formed an expanded empty area, ideal for the development of filamentous fungal mycelium, which gradually destroys the surface and structure of the nail plate.

The development of destructive nail changes caused by fungal infection is caused by three stages (stages).

  1. The initial stage is a type of normotrophic lesion. Occurs central or regional nail destruction. Manifested by spots and stripes on limited areas of the plate.
  2. Middle stage - hypertrophic changes. Characterized by compaction and change the configuration of the nail plate with the spread of the process over its entire area.
  3. Stage dystrophy (hypotrophic) - marked inflammatory reaction okolonogtevogo roller. Infection affects adjacent tissues. Various infections join, the nail plate collapses and crumbles.

Signs of a fungal thumbnail

In the initial stage of infection, the presence of fungal lesions does not show any signs. Sometimes there may be a slight itching, redness and burning in the area of ​​the big toe.

With the growth of mycelium, the symptoms become apparent. The nail structure changes, it becomes brittle and dull. White or yellow spots and stripes appear on the plate.

Sometimes the presence of the fungus confirms the thickened nail plate ingrown corners inside the cushion. This indicates its deformation under the influence of a fungal infection, which is typical for big toes.


  • pain when walking;
  • swelling and redness of the thumb;
  • sometimes purulent discharge from the corners of the plate.
Signs of nail damage

Signs of nail damage

Different variations of the nail plate lesions are explained by the action of a different type of pathogen. Dermotofit fungi are characterized by stripes or spots of yellow color, located along its edges or center.

Moldy fungi stain the plate almost black. Puffiness of the nail cushion, formation of silvery scales on it, yellowness of the sides of the nail and their separation from the bed, provokes the action of yeast fungi.

In the process of vital activity, fungi secrete toxins that destroy not only the nail plates. The development of fungal infection contributes to the penetration of toxins into the system of lymphatic channels, provoking:

  • hypersensitivity of the body, manifested by allergic rashes;
  • disorders of the digestive tract;
  • intoxication symptoms.

Types and principle of treatment of fungal nail infections

treatment of fungal nail infection with Rumikoz The spores of parasitic fungi perfectly and instantly adapt to the upper horny layer of the nail plate, gradually penetrating into the depths of the matrix.

Therefore, the principles of treatment of nail fungus on the big toe are based on a system of local-external and systemic effects. With a purely individual approach, due to signs of pathology and an indicator of the state of the internal systems and organs of the patient.

The principle is based on a complex method of treatment using pulse therapy, systemic, bacterial and external therapy or a simultaneous combination of several techniques.

Pulse therapy. Based on a discontinuous long-term treatment with antimycotic drugs.

The scheme includes:

  • Oral administration of the drug "Rumikoz" or its analogues - weekly intake 2 times / day, 200 mg. Repeat after 3 weeks. The duration of treatment is three courses.
  • Daily for the entire period of treatment - "Lamisil" or an analogue of 1 time / day 250 mg. The tool is able to suppress the development of any pathogenic fungi.

Systemic treatment increases the chance of getting rid of the infection. It is used for significant lesions with clear signs of structural changes in the nail plates of the big toes.

The most popular are:

  1. "Terbinafin" and "Itraconazole" - from 250 to 400 mg. / Day individual course (at least 4 weeks).
  2. Diflucan ” or analogues - 2 times / week, 150 mg each. The course is two months.

With the addition of infection, the treatment is complemented by bacterial therapy. Recommended course of vitamin complexes and immunomodulatory agents.

The effectiveness of treatment with drugs is based on the cumulative principle, when the necessary concentration of drugs provides reliable protection for a long time after stopping treatment.

Therefore it is very important to strictly observe the regimen of administration of drugs and the recommended interval.

External treatment of nail fungus: ointments, creams and varnishes

varnish Lotseril Amorolfin

varnish Lotseril Amorolfin

In addition to treatment, at the initial stages of infectious processes in the nail plates of the thumbs, various methods of external exposure to the infection are applied:

  1. Anti-mycotic properties of lacquer in the form of Lotseril Amorolfin or Batrofen. Once a week a medicinal varnish is applied in two layers on a previously cleaned nail plate. Course duration - from three months to a year.
  2. Anti-mycotic serum "Mikozan" - is applied to the affected area 1 time / day until it is fully restored.
  3. Glue "Dimexidum" is used for resorption of inflammatory processes of the nail shaft.
  4. Processing of nail plates with salicylic, benzoic and lactic acid, tar and sulfur preparations.
  5. Sulfuric and salicylic ointment for the treatment of nail fungus of the thumb applied up to 3 times / day. The course of application depends on the condition of the nail.

The appointment must give a doctor.

With significant damage to the plate, it is most advisable to remove it. The urea ointment is applied to the affected area as a compress overnight. Or use for this purpose a special medical patch.

The nail plate is softened, it is trimmed and the remnants of fragments are removed, followed by treatment with antiseptics. Until the new nail has grown, the site is smeared twice a day with Exoderil ointment or other anti-mycotic ointments.

Folk methods

Treatment of fungus of the big toe folk methods

As an alternative method is carried out:

Iodine treatment - in the form of wiping the affected area 2 times / day until full recovery.

Lemon - during the week, a slice of lemon is fixed to the affected nail with cellophane and a bandage. Lemon treatment has been known for a long time and shows good results.

Hydrogen peroxide - the effectiveness of the treatment of nail fungus with hydrogen peroxide is proved by time. Before you attach the peroxide compress (cotton swab) to the nail plate, it must be steamed in hot water with the addition of several copper sulfate crystals (vitriol) and dried.

Compress time is up to half an hour until the plate brightens. The softened areas are scraped off and lubricated with any antifungal cream.

Prevention of nail foot fungus

In addition to the exclusion of all causal factors, the main rule of disease prevention:

  • proper hygienic care of feet and toes;
  • daily water cleansing procedures;
  • the use of essential oils, lotions and creams to moisturize the skin;
  • proper filing and timely removal of ingrown corners of the nail and keratinized skin.

If you still had to walk away in foreign slippers, or bare feet in public places, treat your feet with antifungal agent.

If you can not buy it, wipe your feet with a solution of citric acid or squeezed out lemon juice. Strengthen immunity, eat right, exercise and it will not leave a chance for the development of a fungal infection.
