Fungal nail infections, also known as tinea unguium, are usually not serious but can take a long time to treat. Toenails are more commonly affected than fingernails, with the infection causing the nail to become discoloured, thickened, brittle, and distorted. The infection often starts at the edge of the nail and spreads to the rest, and can sometimes cause the whole nail to fall off. Treatment options include antifungal nail paints, tablets or capsules, and laser treatment, but relapses are common.

What You'll Learn
Treatment options
Fungal nail infections are usually not serious, but they can take a long time to treat. Treatment options depend on the type and severity of the infection, as well as individual patient factors.
Medication
Antifungal medications are a common treatment option for fungal nail infections. These can be applied topically, such as antifungal nail paints, or taken orally in the form of tablets or capsules. Oral antifungals include griseofulvin, terbinafine, and itraconazole. However, oral antifungals may not be suitable for everyone, especially those with liver disease or pregnant women, as they can cause side effects and interact with other medications. Topical treatments are generally safer, but less effective, with a clearance rate of around 15-30%.
Nail Removal
In some cases of severe infection, the nail may need to be removed. This is a minor procedure performed under local anaesthesia.
Home Remedies
Some home remedies may help manage symptoms and prevent the spread of the infection. Keeping the feet cool, dry, and clean is important, as fungi thrive in warm, moist environments. Wearing breathable footwear, cotton socks, and clean socks every day can help. Avoiding walking barefoot in communal areas, such as public showers and gyms, can also reduce the risk of infection and prevent the spread to others.
Medical Procedures
In addition to medication, some medical procedures may be considered for treating fungal nail infections. For example, debridement, or the removal of damaged nail material, can be performed to improve the penetration of topical treatments. Additionally, laser treatment is an option, although it is generally less effective than paints and oral medications.
Prevention
Preventative measures are crucial in managing fungal nail infections. Avoiding behaviours that can increase the risk of infection, such as sharing nail clippers and scissors, is important. When getting a pedicure, ensuring the salon is clean and sterilises its instruments is essential.

Prevention
Fungal nail infections are usually not serious, but they can be difficult to cure and may take a long time to treat. They are caused by a variety of fungi, including dermatophytes, yeasts, and moulds. The fungi thrive in warm, dark, and moist environments, and they can spread from person to person. Therefore, it is important to take preventive measures to lower the risk of infection. Here are some ways to prevent fungal nail infections:
Keep Your Nails Clean and Trimmed: Maintaining good nail hygiene is essential. Wash and dry your hands and feet regularly, especially after any activity that causes sweating. Keep your nails trimmed and avoid cutting the cuticles. If you have toenail fungus, check your feet regularly for cuts and abrasions, as these can provide an entry point for the fungus.
Wear Protective Gear: When using shared facilities like communal showers or gyms, wear flip-flops or shower shoes to protect your feet from coming into direct contact with potentially contaminated surfaces. Additionally, if your job or hobbies involve exposure to chemicals or other substances that can irritate the nails, wear gloves to protect your hands.
Choose Breathable Footwear: Opt for shoes and socks made from breathable materials, such as leather or cotton. Synthetic materials can trap moisture and create an ideal environment for fungal growth. Allowing your feet to breathe helps keep them dry and reduces the risk of infection.
Treat Other Fungal Infections: Fungal infections, such as athlete's foot, can spread to your nails. Therefore, it is important to treat any fungal infections on your skin promptly. Antifungal creams or powders can be used to treat athlete's foot and prevent the fungus from spreading to your nails.
Practice Good Foot Hygiene: Keep your feet clean and dry, especially between the toes. Fungi thrive in warm, moist environments, so reducing moisture can make it harder for the fungus to grow. Change your socks regularly, and avoid sharing shoes or towels with others to lower the risk of contracting a fungal infection.
Fungal nail infections can be bothersome and challenging to treat. By taking these preventive measures, you can significantly reduce your risk of developing a fungal nail infection and maintain healthy, infection-free nails.

Diagnosis
Fungal nail infections are usually diagnosed clinically. Your doctor may take a small sample of the abnormal nail and send it to a laboratory to check if fungus can be seen under a microscope or grown in culture. This process can take several weeks, and sometimes repeated samples are required. Many nail problems can look like a fungal infection, such as an old injury, bacterial infection, nail psoriasis, or onychogryphosis (a condition common in older people where the nail is thickened, but not due to infection). Therefore, correctly identifying the cause of the nail problem is important before beginning treatment.
Dermoscopy may be used to differentiate between onychomycosis, traumatic onycholysis, and melanonychia. Common dermatoscopic findings include linear bands that round proximally and taper distally, discolouration, non-longitudinal homogenous or reverse triangular patterns, subungual keratosis, white/yellow streaks, and nail plate scales. The pattern of fungal invasion can be further divided into:
- Superficial onychomycosis – white patches on the distal nail
- Proximal subungual onychomycosis – involvement of the proximal nail fold under the surface to distal
- Distal and lateral subungual onychomycosis – the distal end and sides of the nail lift or become discoloured and crumble
- Superficial white onychomycosis – flaky, white patches and pits appear on the top of the nail plate
- Proximal subungual onychomycosis – the proximal nail plate close to the lunula becomes discoloured and thickened. This pattern is often related to underlying HIV infection
- Endonyx onychomycosis – milky white discolouration of the nail plate develops without subungual hyperkeratosis or onycholysis
The Onychomycosis Severity Index can be used to predict response to therapy. Patient or pathogen factors such as poor circulation, advancing age, diabetes, immunosuppression, severe fungal nail clinical findings, mixed infections, and incomplete treatment can cause relapses.

Symptoms
Fungal nail infections are usually not serious and can be left untreated. However, they can take a long time to treat and have a high rate of recurrence. They are caused by fungi that thrive in warm, dark, and moist environments, such as the feet. These infections often affect the toenails, but they can also occur on the fingernails.
Fungal nail infections cause the nail to become discoloured, thickened, brittle, and distorted. The nail may turn yellow, white, or brown, and crumble or break easily. The infection usually starts at the edge of the nail and spreads to the rest of it. Sometimes, the whole nail can break off, causing pain and swelling in the surrounding skin.
The pattern of fungal invasion can be categorised into four types:
- Distal and lateral subungual onychomycosis: The distal end and sides of the nail lift or become discoloured and crumble.
- Superficial white onychomycosis: Flaky, white patches and pits appear on the top of the nail plate.
- Proximal subungual onychomycosis: The proximal nail plate close to the lunula becomes discoloured and thickened. This type is often associated with underlying HIV infection.
- Endonyx onychomycosis: The nail plate develops a milky white discolouration without subungual hyperkeratosis or onycholysis.
Fungal nail infections can be difficult to distinguish from other nail conditions, such as nail psoriasis, bacterial infections, old injuries, or onychogryphosis (a condition common in older people characterised by thickened nails). Therefore, a doctor may take a small sample of the nail for laboratory testing to confirm the presence of a fungal infection.

Causes
Fungal nail infections are caused by fungi that thrive in warm, dark, and moist places, such as the feet. These fungi can multiply and lead to infections. The most common type of fungus that causes nail infections is the same one that causes athlete's foot.
Infections often start at the edge of the nail and spread to the rest of the nail, causing it to become thick, discoloured, brittle, and crumbly. Toenails are more commonly affected than fingernails, and multiple nails can be infected.
Fungal nail infections can spread from other people, so walking barefoot in places like communal showers and gyms increases the risk of contracting the infection. Having a pedicure can also increase the risk if the salon does not maintain proper hygiene standards.
Additionally, wearing trainers for extended periods, resulting in hot and sweaty feet, can increase the likelihood of developing a fungal nail infection.
