What are the symptoms of fungal nail infections. How can you prevent toenail fungus. Who is at risk for developing fungal nail infections. What are the most effective treatment options for ringworm of the toenail.

The Nature and Prevalence of Fungal Nail Infections

Fungal nail infections, medically termed “onychomycosis,” are a common ailment affecting millions worldwide. These infections primarily target the toenails, though fingernails can also be affected. Recent studies suggest that up to 14% of the general population may experience fungal nail infections at some point in their lives, with toenail infections being significantly more prevalent than those affecting fingernails.

But what exactly causes these persistent infections? Fungal nail infections result from various types of fungi that thrive in our environment. These opportunistic microorganisms can invade through small cracks in the nail or surrounding skin, leading to an infection that can be both unsightly and uncomfortable.

Recognizing the Signs of Fungal Nail Infections

How can you tell if you have a fungal nail infection? While these infections are rarely serious from a medical standpoint, they can cause considerable discomfort and cosmetic concerns. The most common symptoms include:

• Discoloration of the nail (often yellowing or browning)
• Thickening of the nail plate
• Increased fragility or brittleness
• Cracking or splitting of the nail
• Separation of the nail from the nail bed (onycholysis)

It’s worth noting that individuals with fungal toenail infections often simultaneously experience fungal skin infections on their feet, particularly between the toes. This condition is commonly known as athlete’s foot or tinea pedis.

Risk Factors and Susceptibility to Fungal Nail Infections

While anyone can develop a fungal nail infection, certain factors can increase an individual’s susceptibility. Who is most at risk for developing these persistent infections?

• Older adults
• Individuals with nail injuries or foot deformities
• People with a history of trauma to the nail
• Diabetics
• Those with weakened immune systems (e.g., due to cancer or certain medications)
• Individuals with poor circulation in the legs (venous insufficiency) or peripheral arterial disease
• People with fungal skin infections on other parts of the body

It’s crucial to note that for individuals with compromised immune systems or conditions like diabetes, fungal nail infections can potentially lead to more serious complications. In rare cases, a bacterial infection may develop on top of the fungal infection, necessitating prompt medical attention.

Preventive Measures Against Fungal Nail Infections

How can you protect yourself from fungal nail infections? While it’s not always possible to prevent these infections entirely, several practical steps can significantly reduce your risk:

1. Maintain good hand and foot hygiene, keeping them clean and dry
2. Keep your nails trimmed and clean
3. Avoid walking barefoot in public areas like locker rooms or showers
4. Don’t share personal items like nail clippers
5. When visiting nail salons, ensure they follow proper sterilization procedures

By incorporating these habits into your daily routine, you can create an environment that’s less hospitable to fungal growth, thereby reducing your risk of infection.

Diagnosing Fungal Nail Infections: The Importance of Professional Assessment

Why is professional diagnosis crucial for fungal nail infections? While the symptoms of fungal nail infections can be distinctive, other conditions can present similarly. This makes it essential to seek a proper diagnosis from a healthcare provider before beginning treatment.

How do healthcare professionals diagnose fungal nail infections? The process typically involves:

1. Visual examination of the affected nail(s)
2. Collection of a nail clipping for microscopic examination
3. Laboratory testing of the nail sample to identify the specific fungal species

This thorough diagnostic approach ensures that the correct treatment is prescribed, avoiding the unnecessary use of antifungal medications for conditions that may mimic fungal infections.

Treatment Options for Fungal Nail Infections

What are the most effective treatments for fungal nail infections? Treatment can be challenging and often requires patience, as these infections tend to be stubborn and slow to resolve. The most common treatment options include:

• Oral antifungal medications: These prescription pills are often the most effective treatment, taken over several months.
• Topical antifungal treatments: While less effective than oral medications, these can be useful for mild cases or as a preventive measure.
• Nail removal: In severe cases, complete removal of the affected nail may be necessary.

How long does treatment typically take? It’s important to understand that treatment can take several months to a year for the infection to fully clear. Even after successful treatment, there’s a risk of recurrence, particularly in individuals with predisposing factors.

The Importance of Comprehensive Treatment

Why is it crucial to treat all fungal infections simultaneously? Fungal nail infections often coexist with fungal skin infections. Failing to treat all affected areas can lead to reinfection. Therefore, it’s essential to discuss all skin concerns with your healthcare provider to ensure comprehensive treatment.

The Potential for Systemic Spread: Addressing Common Concerns

Can toenail fungus spread to other parts of your body? This is a common concern among those affected by fungal nail infections. While it’s rare for toenail fungus to spread internally to organs like the stomach, it’s not impossible, especially in individuals with compromised immune systems.

The fungi responsible for most nail infections (dermatophytes) primarily thrive on keratin, a protein found in nails, skin, and hair. This limits their ability to infect internal organs. However, other types of fungi, such as nondermatophyte molds or yeasts, can potentially cause more widespread infections in immunocompromised individuals.

The Contagious Nature of Toenail Fungus

Is toenail fungus contagious? Yes, toenail fungus can spread from person to person or from one part of the body to another. Common modes of transmission include:

• Direct contact with an infected individual
• Sharing personal items like towels or shoes
• Walking barefoot on contaminated surfaces, especially damp floors
• Contact with infected animals, particularly dogs

Understanding the contagious nature of these infections underscores the importance of preventive measures and prompt treatment.

Debunking Myths: The Severity of Toenail Fungus

Can toenail fungus be life-threatening? For most healthy individuals, toenail fungus is not a serious health threat. However, in rare cases involving immunocompromised individuals, certain types of fungal infections can potentially spread throughout the body and cause severe complications.

It’s crucial for individuals with weakened immune systems, such as those undergoing chemotherapy or living with HIV/AIDS, to seek prompt medical attention if they suspect a fungal nail infection. Early intervention can prevent potential complications and ensure appropriate treatment.

Additional Preventive Strategies

How else can you protect yourself from toenail fungus? Beyond basic hygiene practices, consider these additional preventive measures:

• Wear breathable footwear and moisture-wicking socks
• Use antifungal powders or sprays in your shoes
• Avoid prolonged exposure to moisture, especially when wearing closed-toe shoes
• Regularly inspect your feet and nails for any signs of infection
• Maintain good overall health to support your immune system

By incorporating these habits into your daily routine, you can significantly reduce your risk of developing fungal nail infections and promote overall foot health.

The Role of Nail Care in Preventing and Managing Fungal Infections

How does proper nail care contribute to preventing fungal infections? Maintaining healthy nails is a crucial aspect of fungal infection prevention and management. Here are some key nail care practices to consider:

1. Keep nails trimmed and smooth to reduce the risk of injury and fungal invasion
2. Use sanitized nail tools and avoid sharing them with others
3. Moisturize your nails and cuticles to prevent dryness and cracking
4. Avoid using artificial nails or nail polish on infected nails, as these can trap moisture and exacerbate the infection
5. When visiting nail salons, ensure they follow proper sterilization procedures for all tools and equipment

By incorporating these practices into your regular nail care routine, you can create an environment that’s less hospitable to fungal growth and promote overall nail health.

The Impact of Lifestyle Factors on Fungal Nail Infections

How do lifestyle choices influence the risk of fungal nail infections? Several lifestyle factors can significantly impact your susceptibility to these infections:

• Footwear choices: Tight, non-breathable shoes can create a warm, moist environment ideal for fungal growth
• Physical activity: Frequent intense exercise, especially in hot, humid conditions, can increase the risk of fungal infections
• Occupation: Jobs that require prolonged standing in damp conditions or frequent hand-washing can increase susceptibility
• Swimming: Regular use of public pools or communal showers can expose you to fungi
• Travel: Visiting tropical or subtropical regions can increase exposure to fungal organisms

Understanding these risk factors can help individuals make informed choices to reduce their chances of developing fungal nail infections.

The Psychological Impact of Fungal Nail Infections

How do fungal nail infections affect an individual’s mental well-being? While often considered primarily a cosmetic concern, fungal nail infections can have significant psychological impacts on those affected. Common emotional responses include:

• Embarrassment or self-consciousness about the appearance of affected nails
• Anxiety about potential spread of the infection
• Frustration with the slow progress of treatment
• Depression related to chronic nature of the condition
• Social withdrawal due to fear of stigma or contagion

Recognizing these psychological effects is crucial for healthcare providers to offer comprehensive care that addresses both the physical and emotional aspects of fungal nail infections.

Coping Strategies for Living with Fungal Nail Infections

What strategies can help individuals cope with the challenges of fungal nail infections? While treatment is ongoing, consider these approaches:

1. Educate yourself about the condition to dispel myths and reduce anxiety
2. Join support groups or online communities to connect with others experiencing similar challenges
3. Practice good self-care, including stress management techniques
4. Consider cosmetic solutions like nail polish (if approved by your healthcare provider) to temporarily improve nail appearance
5. Focus on overall health and wellness to support your body’s natural defenses

By employing these strategies, individuals can better manage the emotional impact of fungal nail infections while undergoing treatment.

Emerging Research and Future Treatments for Fungal Nail Infections

By supporting and participating in this research, both healthcare providers and patients can contribute to advancing our ability to manage and prevent fungal nail infections more effectively.

Fungal Nail Infections | Fungal Diseases

Fungal nail infections, also known as “onychomycosis,” are very common. They may affect up to 14% of the general population. Fungal toenail infections are more common than fungal fingernail infections.¹

Symptoms

Most fungal nail infections are not serious. However, some people may experience pain or be bothered by the appearance of their nails.

Fungal nail infections may cause nails to become discolored, thick, fragile, or cracked. The nail may also become separated from the nail bed.

People who have fungal toenail infections often have a fungal skin infection on the foot, especially between the toes (commonly called athlete’s foot, ringworm on the foot, or tinea pedis).

How does someone get a fungal nail infection?

Fungal nail infections are caused by many different types of fungi that live in the environment. Small cracks in your nail or the surrounding skin can allow these germs to enter your nail and cause an infection.

Who gets fungal nail infections?

Anyone can get a fungal nail infection. Some people may be more likely than others to get a fungal nail infection, including older adults and people who have the following conditions: ^2,3

• A nail injury or foot deformity
• Trauma
• Diabetes
• Weakened immune system (for example, because of cancer)
• Venous insufficiency (poor circulation in the legs) or peripheral arterial disease (narrowed arteries reduce blood flow to the arms or legs)
• Fungal skin infections on other parts of the body

Occasionally, a bacterial infection can occur on top of a fungal nail infection and cause serious illness. This is more common in people with diabetes or other conditions that weaken the body’s defenses against infection.

Prevention

• Keep your hands and feet clean and dry.
• Keep fingernails and toenails short and clean.
• Don’t walk barefoot in areas like locker rooms or public showers.
• Don’t share nail clippers with other people.
• When visiting a nail salon, choose a salon that is clean and licensed by your state’s cosmetology board. Make sure the salon sterilizes its instruments (nail clippers, scissors, etc.) after each use, or bring your own.

Diagnosis

Fungal infections are not the only possible cause of nail problems. Other conditions can look similar to fungal nail infections.

Your healthcare provider should generally confirm your diagnosis using laboratory testing before prescribing antifungal treatment. To confirm the diagnosis, the healthcare provider might collect a nail clipping to look at under a microscope or to send to a laboratory for testing.

Treatment

Fungal nail infections can be difficult to cure, and treatment is most successful when started early. Fungal nail infections typically don’t go away on their own, and the best treatment is usually prescription antifungal pills taken by mouth. In severe cases, a healthcare professional might remove the nail completely. It can take several months to a year for the infection to go away.

Fungal nail infections can be closely associated with fungal skin infections. If a fungal infection is not treated, it can spread from one place to the other. Patients should discuss all skin concerns with their healthcare provider to ensure that all fungal infections are properly treated.

Even after treatment, fungal nail infections can come back. This is more common in people who have conditions like diabetes that make them more likely to get a fungal nail infection. If you suspect an infection has returned, contact your healthcare provider.

Information for healthcare professionals

You asked, we answered: Can toenail fungus spread to other parts of your body?

Question:

If you have toenail fungus, how likely is it to be in your stomach and other parts of your body?

Answer by dermatologist Corey Georgesen, MD:

Toenail fungus is a nail infection usually caused by unique fungi called dermatophytes. These fungi may be found on the skin of humans, animals or in soil. Dermophytes can also cause ringworm and fungal scalp infections. 

Toenail fungus doesn’t usually spread to inside your body, like the stomach. The fungi require keratin, found in your hair, skin and nails. They survive best on the skin.

Is toenail fungus contagious?

Yes, toenail fungus is contagious. 

Typically toenail fungus spreads through: 

• Direct contact with the infected person 
• Common household objects, such as towels or clothing 
• Surfaces, especially damp floors
• Animals, most commonly dogs

Can toenail fungus kill you?

Other types of toenail fungus – caused by nondermatophyte molds or yeast – can spread throughout the body. They can cause death in those without an immune system. These infections are rare. If you’re immunocompromised, seek care quickly if you suspect a toenail fungus.

How to prevent toenail fungus

Prevent toenail fungus by avoiding fungi-friendly places:

1. Do not share towels, combs, clothing or anything else with an infected person.
2. Wear sandals when using public shower facilities and around swimming pools. 
3. Change wet socks after exercise, as fungi thrive in moist, dark environments.  

If you’re prone to skin fungal infections, consider using antifungal cream in your toe web spaces. This area is a natural hiding spot for fungi on the skin.

What toenail fungus cures work?

Toenail fungus can be difficult to treat. The typical treatment for toenail fungus is up to three months, which is why it’s important to start treatment early. Normally it takes six to nine months for a toenail to grow out. 

Treatments for toenail fungus include:

• Topical creams
• Nail lacquer
• Spray
• Oral medications

Which doctor treats toenail fungus?

Dermatologists are trained to diagnose and treat toenail fungus accurately. They can also do laboratory testing if needed. If you have thickening, yellowing or other changes in the toenails, see a certified dermatologist quickly.

You can call 800.922.0000 to make an appointment with a Nebraska Medicine dermatologist.

Ringworm in humans

Ringworm is a fungal and highly contagious disease caused by fungi Microsporum, Trichophyton, etc. You can become infected with ringworm only through direct contact with the carrier of the fungus – pets, a person suffering from this disease, household appliances, toys. At the same time, in a person who has become infected from an animal, the process of treating ringworm takes much longer, and the disease itself proceeds in a more severe form. Most often, ringworm in humans affects the scalp and scalp. Much less often, the disease appears on the eyelashes, feet and nails. According to statistics, it is children who most often suffer from this disease and are carriers of the fungus.

– appearance of red spots on human skin. Spots, initially covered with a crust or scales, eventually become covered with tiny bubbles. In places where the spots are localized, there is severe itching;
– the appearance of rounded bald spots in the hair. The hair in these places is very thin and short;
– deterioration of hair health in general;
– thickening and delamination of the nail plate;
– with weak immunity, weakness, headache or fever may occur.

Due to the fact that each organism is individual and reacts to the fungus in completely different ways, there are several forms of ringworm in humans :

1. In the papular-squamous form, lichen appears on the chest or face;
2. In the abortive form, the symptoms of the disease are mild. On the skin, only pale foci of localization of the fungus can be observed, which do not have clear boundaries;
3. When the palms and feet are affected, dry plaques are observed, similar in appearance to ordinary corns;
4. The erythematous-edematous form most often occurs in children. Severe inflammation occurs at the site of the spots. Often this form of the disease is accompanied by allergies;
5. When the form is deep, subcutaneous nodes appear on the legs. As a rule, women get sick with this form of lichen;
6. Microsporic onychomycosis affects the nail plate. The nail is covered with dull spots, becomes brittle and collapses over time;
7. Suppurative-infiltrative form is considered the most severe form of the disease. It is characterized by swollen dense plaques, severe itching and purulent discharge.

To combat ringworm in a person, the doctor prescribes medication to the patient with external and internal antifungal drugs with the active ingredient Ketoconazole , Terbinafine , Clotrimazole , Mikoseptin . For deep lesions of the skin, hair or nails, apply Griseofulvin .

As a rule, with complex and correct treatment, the disease recedes after a few weeks. To prevent the occurrence of repeated plaques, it is recommended to complete the entire course of treatment to the end. Also, the patient is prescribed a special diet, including vegetables, meat, fruits, milk and sour-milk drinks.
