What Is a Fungal Nail Infection?
A fungal nail infection, or onychomycosis, is caused by the overgrowth of fungal organisms in, under, or on the nail. It most commonly affects toenails but can also occur in fingernails. The condition typically develops slowly, and early signs include:
- Yellow, white, or brown discolouration
- Thickened or brittle nails
- Crumbly or flaky texture
- A distorted or lifted nail shape
- Foul odour or nail detachment in advanced stages
The infection can affect one or multiple nails and is more prevalent in adults, especially those with diabetes, weakened immune systems, or poor foot hygiene, as well as those with a history of athlete’s foot or repeated nail trauma.
Why Fungal Nail Infections Shouldn’t Be Ignored
Although it may seem like a minor cosmetic concern, a fungal nail infection can spread and lead to:
- Chronic discomfort while walking
- Secondary skin infections like athlete’s foot
- Permanent nail damage
- Embarrassment or anxiety over the appearance of your feet or hands
Getting early, effective treatment from a qualified podiatrist or chiropodist in London can prevent further complications and improve your nail health.
When to See a Podiatrist Urgently
Contact us promptly if the nail is painful, leaking pus, surrounded by red or inflamed skin, or if you have diabetes or a weakened immune system — fungal nails can lead to serious secondary infections without early care.
Common Causes of Fungal Nail Infection
Understanding what causes the infection can help in preventing recurrence. Risk factors include:
- Existing fungal skin infections (e.g. athlete’s foot)
- Nail trauma or damage from pedicures or manicures
- Diabetes, psoriasis, or compromised circulation
- Excessive use of nail polish or acrylic nails
- Damp environments like communal showers, gyms, or swimming pools
- Wearing tight, non-breathable shoes
- Poor foot hygiene and prolonged moisture exposure
How We Treat Fungal Nail Infections at Flawless Feet
At Flawless Feet Podiatry & Laser Clinic, we offer a comprehensive approach to treating fungal nail infection using the latest technologies combined with expert podiatric care. Depending on the severity and nature of your condition, we may recommend one or more of the following options:
1. Laser Therapy – Our Leading Solution
We are proud to offer two innovative laser options:
S30 Podylas™ Laser
A state-of-the-art laser that delivers focused energy to eradicate fungal cells beneath the nail without harming surrounding tissue.
Lunula “Cold” Laser
A pain-free, low-level laser therapy (LLLT) that targets the infection while stimulating nail regeneration and immune response.
Benefits of Laser Treatment:
- Pain-free and non-invasive
- No side effects or liver risks (unlike oral medication)
- Suitable for most patients
- Proven clinical effectiveness
- Typically completed in 4 sessions spaced two weeks apart
2. Topical Antifungal Therapy
For mild infections, medical-grade lacquers or oils may be prescribed. We combine these with professional nail debridement to enhance penetration and maximise results.
3. Oral Antifungal Medication
While oral tablets can be effective, they may carry side effects—especially for those with liver concerns. We generally reserve this option for more advanced or resistant infections, with your health and safety as top priority.
What Happens After Fungal Nail Treatment?
Looking after your nails properly after treatment is key to a lasting result. Here's what to expect and how to care for your feet:
- Immediately after treatment — you can return to normal activity straight away; laser treatment requires no recovery time.
- Nail regrowth — the infected nail won't look clear overnight. Healthy nail grows out slowly, with full improvement typically visible over 6–12 months.
- Between sessions — keep feet clean and dry, change socks daily, and apply any prescribed topical treatments as directed.
- Footwear hygiene — disinfect shoes and avoid sharing footwear to prevent reinfection from spores living in old shoes.
- Follow-up reviews — we monitor your progress at each session and adjust your treatment plan as your nails recover.
Your podiatrist will give you personalised aftercare advice at every appointment, so you know exactly how to protect your results.
