Toenail Fungus – Symptoms, Pictures, Treatment, Home Remedies and Cure

What is Toenail Fungus?

The most common of all the nail abnormalities that usually causes a discoloration, dis-figuration and the eventual destruction of the toenail is called Toenail Fungus. It has in its favor several medical terms, namely Onychomycosis, Tinea unguium and Ringworm of the nail. It is a kind of an infection caused by a fungal group known as Dermatophytes and as such is also known as Dermatophytic onychomycosis. The moist warm environment that persists within the shoes are usually the breeding ground for the growth of the Dermatophytes who feed on the keratin or the protein rich portion of the toenails which renders the hardness and the strength to the nail.

Types of Toenail Fungus

Medical experts have classified toenail fungus into 4 basic types on the basis of the type and extent of fungal infection. They are as the following:-

  • Distal Subungual Onychomycosis is perhaps the most common form of Toenail fungal infection that is caused by a fungus named Trichophyton rubrum. This fungus is dangerous in the sense that it tries to cause harm to the toenail by forcefully entering the nail bed and making its way beneath the nail plate to feed and destroy the keratin present.
  • Another very commonly seen toenail and fingernail fungal infection is the one caused by keeping the fingers underwater either for a long period of time or frequently exposing them to the same. This kind of an infection is known as Candida Onychomycosis as it is caused by the action of the candida species of fungus.
  • Proximal Subungal Onchomycosis is a kind of tinea unguium that usually affects those whose immune systems are relatively weak and compromising. Here the fungus tries to invade through the proximal nail fold to the nail plate and subsequently the nail bed.
  • The formation of ‘white islands’ on the nail due to the erosion of the superficial layers of the nail due to fungal invasions is known as White Superficial Onychomycosis. However, it only accounts for a fraction of cases dealing with onychomycosis but may be confused for Keratin Granulations which cause a chalky appearance of the nail owing to the harmful effects of the use of nail polish.

The aged are the most affected by toenail fungus and diabetics and HIV patients are highly prone to the same.

Is Toenail Fungus Contagious?

Toenail fungus as a disease is highly contagious in nature and can very easily spread from one to another if ignored. Showers in the bathrooms and the locker rooms are the primary places where one can easily come in contact with the pathogens of the disease if the place is uncleaned or unhygienic.

Toenail Fungus Symptoms

The symptoms of toenail fungus are quite discernable as the infection causes the nail to lose its color and as such turn abnormally yellowish, brownish or whitish. This is accompanied by the over thickness and roughness of the nail and its crumbling thereby leading to its complete separation from the nail bed. If the toenail fungus is accompanied with skin lesions or fungal infections in other parts of the body, rashness or itching may occur in the new area of the body. The excessive thickness of the nail and its overgrowth makes it highly difficult to wear shoes at this point of time. Fluids may be discharged from the affected area due to the accumulation of debris on the sides of the nail causing it to smell foul and pungent. The severity of this state may lead to the eventual falling off of the nail and the subsequent growth of an inborn toe nail and its infection. If ignored, this may perpetuate to paronychia and onycholysis, which are other kinds of nail disorders and infections.

What causes Toenail Fungus?

Toenail Fungus is primarily caused by poor maintenance of personal hygiene. Since the disease is contagious in nature, any act of sharing personal belongings such as shoes or socks may pass on the disease to the other person. an apt environment for the growth of the fungus causing toenail fungus is created automatically if one keeps wearing the same shoes or socks for a long perod of time.

Types of Fungus causing Toenail Fungus

The fungus causing Toenail fungus are basically of three types :

  • Dermatophytes such as Tricophyton rubrum are considered to be the most common pathogen causing toenail fungus. Other dermatophytes causing the same include Tricophyton interdigitale, Tricophyton violaceum, Trycophyton veruccosum (commonly known as cattle ringworm), Epidermophyton floccosum, Microsporum gypseum, and others.These are supposed to be the found in the temperate climatic zones of the western world.
  • The Candida is a water borne fungus that affects those who always have the tendency to submerge their hand or feet underwater.
  • And the non-dermatophytic pathogens of toenail fungus include the Scytalidium, Aspergillus, Scopulariopsis which affect people living in warm and humid climate.

Other factors contributing to onychomycosis include heredity, aging, athletic and fitness activities in public places, the use of public toilets and bathrooms, occlusive footwear, low pH level of the skin, wet feet, and immunosupression such as HIV.

Toenail Fungus Treatment and Cure

Although treating onychomycosis is somewhat difficult and time consuming due to the complexity involved in the infection of the nails yet there are several treatments for those wondering as to how to get rid of Toenail Fungus? They can be subdivided into 2 broad categories:-

Pharmocological or Medical Treatment

The pharmacological methods can be categorised into two types, namely systemic antifungal and topical toenail fungus treatment.

In the case of anti-fungal medications, itraconazole and terbinafine are suggested. Whereas in the case of topical medications, Amorolfine and Ciclopirox are used to cure oneself of toenail fungus. However the best method to cure this disease is to use the combination of both systemic and topical therapies. An example of such a therapy include nail lacquer which is a method of applying the same on the nails for a consistent period which may extend upto a year or more to cure.

Along with these, oral medications are also available to get rid of toenail fungus. The duration of this medication depends on the severity of toenail infection and the time taken by the infected nail to shed in order to make space for a new nail in its place. Some of them are the Fluconazole or Diflucan and Terbinafine in the form of Lamisil. However, warm and moist environmental exposure to the affected nail may delay the healing period and aggravate the situation. But this method is not recommended by the doctors because of its own perils such as stomach upset, allergies, headache, skin rashes which may be precipitated by underlying causes of the damage to the lever. The oral intake of these may lead to heart failure in severe cases.
