Nail fungal infections, also called onychomycosis, are a common condition affecting millions of people worldwide. The condition occurs when fungi infect one or more of your nails. It can lead to discolored, thickened, and crumbly nails that can be painful to touch. In this article, we will discuss everything you need to know about nail fungal infections, including the types, causes, symptoms, diagnosis, treatment, and prevention.
Understanding Nail Fungal Infections
Nail fungal infections can affect any nail on your hands or feet, but they are more common in toenails than fingernails. The infection starts at the edge of the nail and gradually spreads across the entire nail. In some cases, the fungal infection can lead to the complete loss of the nail.
There are several risk factors that can increase your chances of developing a nail fungal infection. These include having a weakened immune system, wearing tight-fitting shoes, and walking barefoot in public places such as swimming pools and locker rooms. Additionally, people who have a history of athlete’s foot or other fungal infections are more likely to develop nail fungal infections.
If left untreated, nail fungal infections can cause discomfort and pain, and may even lead to complications such as cellulitis, a skin infection. Treatment options for nail fungal infections include topical and oral antifungal medications, as well as laser therapy. It is important to seek treatment as soon as possible to prevent the infection from spreading and causing further damage to the nail and surrounding skin.
Types of Nail Fungal Infections
There are four types of nail fungal infections that can affect your nails, including:
- Distal subungual onychomycosis – the most common type that affects the nail bed and the underside of the nail plate.
- White superficial onychomycosis – a fungal infection that affects the topmost layer of the nail.
- Proximal subungual onychomycosis – a rare type of fungal infection that starts at the base of the nail plate.
- Candida onychomycosis – a fungal infection caused by candida yeast.
It is important to note that nail fungal infections can be difficult to treat and may require long-term medication or topical treatments. In severe cases, surgical removal of the affected nail may be necessary. It is also important to practice good nail hygiene, such as keeping nails clean and dry, avoiding sharing nail clippers or other tools, and wearing protective footwear in public areas like locker rooms and swimming pools to prevent the spread of fungal infections.
What Causes Nail Fungal Infections?
Nail fungal infections are caused by a group of fungi called dermatophytes. These fungi thrive in warm, moist environments such as public swimming pools, locker rooms, and showers. The fungi can enter your nails through tiny cuts or breaks in the skin around your nails.
Another common cause of nail fungal infections is wearing tight-fitting shoes or socks that don’t allow your feet to breathe. This creates a warm, moist environment that is perfect for fungi to grow and thrive. Additionally, people with weakened immune systems, diabetes, or circulation problems are more susceptible to nail fungal infections.
Preventing nail fungal infections involves keeping your feet clean and dry, wearing breathable shoes and socks, and avoiding walking barefoot in public areas. If you do develop a nail fungal infection, there are several treatment options available, including topical and oral medications, laser therapy, and surgical removal of the infected nail.
Risk Factors for Nail Fungal Infections
Several factors can increase your risk of developing a nail fungal infection, including:
- Age – older adults are more prone to nail fungal infections than younger people.
- Poor blood circulation – conditions such as diabetes or peripheral arterial disease can reduce blood flow to your nails.
- Weakened immune system – illnesses such as HIV or chemotherapy can weaken your immune system, making it easier for the fungi to take hold.
- Injury to nails – any damage to your nails can increase the risk of developing a fungal infection.
- Poor hygiene – failing to keep your nails dry and clean can increase your risk of developing a fungal infection.
However, there are other risk factors that can increase your chances of developing a nail fungal infection. One of these is having a family history of fungal infections, as genetics can play a role in susceptibility to the condition.
Additionally, certain occupations can increase the risk of developing a nail fungal infection. People who work in jobs that involve frequent exposure to water, such as dishwashing or cleaning, are more likely to develop the condition due to the prolonged exposure to moisture.
Signs and Symptoms of Nail Fungal Infections
The signs and symptoms of nail fungal infections can vary depending on the severity of the infection, but some common symptoms include:
- Thickened nails
- Discolored nails that may turn yellow, brown, or white
- Crumbling or brittle nails
- Nails that are distorted in shape or have a foul smell
- Nails that are separated from the nail bed
- Pain or discomfort in the affected nail or surrounding area
It is important to note that nail fungal infections can be difficult to treat and may require long-term management. In some cases, the infected nail may need to be removed in order to fully eliminate the infection.
Prevention is key when it comes to nail fungal infections. It is important to keep your nails clean and dry, avoid sharing nail clippers or other tools, and wear shoes in public areas such as locker rooms and showers.
How to Diagnose Nail Fungal Infections?
If you suspect you may have a nail fungal infection, it’s essential to see a healthcare provider. They will examine your nails and may order a laboratory test to confirm the diagnosis. The test typically involves clipping a small piece of your infected nail and examining it under a microscope or sending it to a lab for culturing.
It’s important to note that not all nail abnormalities are caused by fungal infections. Other conditions, such as psoriasis or trauma, can also cause changes in the appearance of nails. Your healthcare provider will be able to differentiate between these conditions and provide appropriate treatment.
Home Remedies for Nail Fungal Infections
While there is no definitive cure for nail fungal infections, several home remedies may help relieve symptoms and promote healing, including:
- Keeping your nails clean and dry
- Trimming your nails regularly and keeping them short
- Soaking your feet in a mixture of warm water and apple cider vinegar or Epsom salts
- Applying tea tree oil or oregano oil to the affected nail
- Applying Vicks VapoRub or menthol-based creams to the affected nail
It is important to note that home remedies may not work for everyone and it is always best to consult with a healthcare professional for proper diagnosis and treatment. In some cases, prescription antifungal medications may be necessary to fully treat the infection. Additionally, it is important to practice good foot hygiene and avoid sharing nail clippers or other personal items to prevent the spread of fungal infections.
Over-the-Counter Treatments for Nail Fungal Infections
If your nail fungal infection is mild, your healthcare provider may recommend over-the-counter topical antifungal creams or ointments such as clotrimazole, miconazole, or terbinafine. These medications work by killing the fungi or preventing them from reproducing. However, they can take several months to show results and may not be effective for severe infections.
In addition to topical treatments, there are also over-the-counter oral antifungal medications available, such as fluconazole and itraconazole. These medications are more effective for severe infections, but they also come with a higher risk of side effects and may interact with other medications. It is important to consult with your healthcare provider before starting any new treatment for nail fungal infections.
Prescription Medications for Nail Fungal Infections
If your nail fungal infection is severe, your healthcare provider may prescribe oral medication such as terbinafine or itraconazole. These medications work by attacking the fungus and preventing it from spreading. However, they can have potential side effects such as liver damage, so it’s essential to follow your healthcare provider’s instructions carefully.
Another option for treating nail fungal infections is topical medication. These medications are applied directly to the affected nail and can be effective for mild to moderate infections. However, they may take longer to work than oral medications and may not be as effective for severe infections.
In addition to medication, there are also lifestyle changes you can make to help prevent nail fungal infections. These include keeping your feet clean and dry, wearing shoes that fit properly and allow your feet to breathe, and avoiding walking barefoot in public places such as locker rooms and swimming pools.
Laser Therapy for Nail Fungal Infections
Laser therapy is a relatively new treatment option for nail fungal infections. It involves using a special laser to heat and destroy the fungi without damaging the surrounding tissue. The treatment is non-invasive and typically requires multiple sessions. However, it can be expensive, and its effectiveness is still under study.
One advantage of laser therapy for nail fungal infections is that it does not have the potential side effects of oral antifungal medications, such as liver damage. Additionally, laser therapy can be a good option for individuals who are unable to take oral medications due to other health conditions or medication interactions. However, it is important to note that laser therapy may not be effective for all cases of nail fungal infections and should be discussed with a healthcare provider.
Preventing Nail Fungal Infections
Preventing nail fungal infections is easier than treating them. Some tips to prevent fungal infections include:
- Keep your nails clean and dry
- Trim your nails regularly
- Wear shoes that fit properly and allow your feet to breathe
- Avoid going barefoot in public places
- Avoid sharing personal items such as nail clippers or shoes
In addition to these tips, it is important to avoid injuring your nails as this can increase the risk of fungal infections. If you do injure your nail, clean the area thoroughly and apply an antifungal cream to prevent infection. It is also recommended to wear protective gloves when doing activities that may damage your nails, such as gardening or washing dishes.
Natural Remedies for Nail Fungal Infections
Several natural remedies may help treat nail fungal infections, including:
- Tea tree oil – applying diluted tea tree oil to the affected nail can help kill the fungi
- Vinegar – soaking your feet in a mixture of warm water and vinegar can help kill the fungi
- Garlic – crushing garlic and applying it directly to the affected nail can help fight fungal infections
In addition to these natural remedies, it is important to maintain good hygiene practices to prevent the spread of nail fungal infections. This includes keeping your nails clean and dry, avoiding sharing nail clippers or other personal grooming tools, and wearing breathable shoes and socks. If your nail fungal infection persists or worsens, it is important to seek medical treatment from a healthcare professional.
Complications of Untreated Nail Fungal Infections
If left untreated, nail fungal infections can lead to several complications, including:
- Permanent nail damage or loss
- Cellulitis – a bacterial skin infection that can spread to other parts of your body
- Sepsis – a life-threatening condition caused by bacteria entering your bloodstream
In addition to the above complications, untreated nail fungal infections can also cause discomfort and pain, making it difficult to perform daily activities. The infection can also spread to other nails and even to other people through direct contact. It is important to seek treatment as soon as possible to prevent further complications and to improve the overall health of your nails.
When to See a Doctor for a Nail Fungal Infection
If you suspect you have a nail fungal infection, it’s essential to see your healthcare provider for an accurate diagnosis and treatment. You should see a healthcare provider if:
