Types Of Toenail Fungal Infections
Toenail infections affect about 14 percent of the population at any given time, according to a study published in June 2014 in PloS Pathogens. The most common symptoms of a toenail fungal infection include discoloration of the nail, debris under the nail, irregularity of the white part of the nail, nail thickening, and pain, says Sheth.
Toenail fungal infections can usually be categorized into one of the following five subtypes:
Distal Subungual Onychomycosis This is the most common form of toenail fungal infection, usually occurring in the portion of the nail closer to the tip and on the underside of the nail. The nail may become thick, yellow, or brittle.
Endonyx Onychomycosis People who have endonyx onychomycosis have fungus growing between the layers of the toenails. With this type of fungus, toenails usually have a milky white color and may be pitted or split. They usually dont thicken or separate from the nail bed.
Proximal White Subungual Onychomycosis This is a relatively uncommon form of toenail fungus, seen most often in people with weakened immune systems due to conditions such as HIV. The fungus enters the toenail through the cuticle and affects the part of the nail closer to the base, turning it a whitish color.
Symptoms Of A Nail Fungus
The most common sign of a fungus of the nail is a thickened surface. Here are some other symptoms in the nails:
- Yellow or Brown Discoloration
- Debris Building Under the Nail
- Dark Coloring
- Impossible to Cut with Clippers Because its too thick
Fungus of the nails if quite common. It often starts as a white spot under the nail that is an annoyance more than anything else. However, as the infection grows and penetrates, you will see it turn colors, become thicker, and crumble. What started as a fungus affecting one nail can quickly spread to other toe or fingernails too.
Some mild conditions that are troublesome may not require treatment. However, when the nail becomes thick, turns colors, or has a foul smell, you can do some home-based therapies. Keep in mind that even if your efforts are successful, the fungus can return.
The same fungus that gets between the toes and causes athletes foot is called tinea pedis, and its not the same as onychomycosis or nail fungi, but having this infection in between the toes can undoubtedly spread to the nails if there is an opening that allows it to creep in.
What Is The Most Effective Treatment For Toenail Fungus
The most effective toenail fungus treatment for you will largely depend on your symptoms and situation. Your provider will consider several factors before recommending a treatment plan thats customized to you.
Overall, oral antifungal medications may offer the most treatment potential. Pairing oral drugs with topical antifungal medication may make treatment more effective.
How To Treat Fungal Nail Effectively
Owing to the high recurrence rate of fungal nail infections, pharmacy professionals should be able to advise patients on effective treatment and preventative and appropriate self-care strategies to avoid re-infection.
Fungal nail infection is a mycotic infection caused by fungal invasion of the nail structure and is one of the most common nail disorders, representing half of nail abnormalities in adults. Its prevalence in Europe is around 4.3% over all age groups and 15.5% of all nail dystrophies in children. OM is more commonly diagnosed in men and older people, affecting 2050% of people aged over 60 years. An increased incidence among older people may be attributed to multiple factors, including reduced peripheral circulation, diabetes, inactivity, relative immunosuppression, and reduced nail growth and quality. Toenails are affected more commonly than fingernails.
This article will cover the causes, types and treatment of OM, practical information to help guide patient consultations and when to refer to podiatry.

Men are more likely to get it than women. The older you are, the better your chances are, too. People who have diabetes, athlete’s foot, or a weak immune system, who smoke, or whose family members have it are also at a higher risk. If you spend a lot of time in the water or you’ve injured your toenail, your odds for getting toenail fungus go up.
How Do You Get A Fungal Nail Infection

These fungi often live harmlessly on your skin, but they can sometimes multiply and lead to infections. The fungi prefer warm, dark and moist places like the feet.
You’re more likely to get a fungal nail infection if you:
- don’t keep your feet clean and dry
- wear shoes that cause your feet to get hot and sweaty
- walk around barefoot in places where fungal infections can spread easily, such as communal showers, locker rooms and gyms
- have damaged your nails
- have a weakened immune system
- have certain other health conditions, such as diabetes, psoriasis or peripheral arterial disease

The newer drugs are unlikely to cause any liver problems in patients without known liver disease. Blood tests are not needed for once-weekly treatment with fluconazole however, people taking longer courses often have their liver function tested before starting the medicine and then retested during the course of treatment. It is important to notify the doctor of all side effects while on the medication. You should tell your doctor of all current medications to prevent potential serious drug interactions.
Difficulties With Nail Infections
While many cases of fungus are mild, some become complicated. When issues are severe, the toxins can cause permanent damage to the nail, and you may lose it. The goal is to keep the infection from spreading to other body areas beyond the feet.
The biggest concern is those who have a compromised immune system, which can be dangerous if the infection gets out of control. Those with Type 2 diabetes can often have circulation issues too that affect their feet. This puts you at a greater risk of developing a bacterial skin infection like cellulitis that can be dangerous.
With diabetes, any infection that affects your feet can be a severe complication requiring prompt medical help. While most dont need to be concerned if there is a small dot of yellow or white under the nail, for the diabetic, its a cause for alarm.

Take Care Of Your Toes
Use soap and water to wash your feet, and dry well, including between toes. Trim your toenails — straight across — to keep them shorter than the end of your toe. Make sure the tools you use are clean, too. Wash clippers and files with soap and water, then wipe with rubbing alcohol. You might be tempted to cover up discolored nails with polish, but don’t. Your nail bed can’t “breathe,” which keeps fungus from going away.
Spread Of Toenail Fungus
The fungi that infects the toenails are easily spread by direct contact with others who have the fungus. It is also commonly transmitted through damp public areas, like gym showers and community pools. Sharing socks, shoes and nail manicuring equipment with a person who has the fungus can also lead to its spread to uninfected individuals. People living in the same household as a person with nail fungus are at greater risk.

The nail bed and nail matrix are vascular components of the nail, with nail cells located within the nail matrix where the nail plate is formed. The thickness of the nail plate determines the length of the matrix

Causes Of Toenail Fungus
As the name suggests, toenail fungus is caused by fungi. There are various types of fungi that can cause toenail fungus. The most common type is called dermatophyte. Other common types of fungi include yeast and molds. The risk factors of toenail fungus are discussed in a later section of this post.
Usually, fungal toenail infection starts from a fungal foot infection called athletes foot. In such cases, toenail fungus develops when the fungi causing athletes foot spreads to and attacks toenails.
However, you can also contract toenail fungus without necessarily having suffered from athletes foot. Normally fungi exist harmlessly on the skin, but under certain conditions, they can multiply and lead to infections. The fungi thrive warm, dark and regularly moist places like the feet.
Toenail fungus can spread from one infected toenail to other healthy ones. This especially happens when your feet are subjected to the conditions that encourage growth and development of the fungi that already exists on your other toes.
You can also get toenail fungus from other people who have fungal infections, whether or not they affect their toenails. Toenail fungus is contagious and hence can spread from one individual to another through direct contact or by sharing items like clothes , shoes or towels. Sometimes, this happens when your feet come into contact with fungi on the ground, especially if you walk barefoot.
