What Is Nail Fungus?
Nail fungus, medically known as onychomycosis, is a
fungal infection that affects the toenails or fingernails, leading to thickening,
discolouration, and brittleness. It is commonly caused by dermatophyte fungi
but can also result from yeast or mould infections. The warm and humid climate in Singapore
creates ideal conditions for fungal growth, increasing the risk of infection.
While often considered a cosmetic concern, untreated nail fungus can cause discomfort, nail
deformity, and, in some cases, interfere with daily activities like walking or wearing
shoes.
At Medical Aesthetics, we offer a range of treatments for nail fungal infections, including
topical and oral medications, as well as advanced options such as nail removal.
What Causes Nail Fungus?
Nail fungus develops when fungi, microorganisms such as moulds,
yeasts, and dermatophytes, enter small cracks in the nail or surrounding skin, leading to
infection. Several factors can increase the risk, including:
Poor Foot Hygiene – Wearing tight, non-breathable footwear or damp
socks for long periods creates an ideal environment for fungal growth.
Prolonged Exposure to Moisture – Using communal showers, gym locker
rooms, or walking around poolside areas without protective footwear can increase fungal
contact.
Nail Trauma – Injuries, nail biting, or improper trimming can damage
the nail, creating openings for fungi to enter and cause
infection. Trauma may also reduce local blood circulation, weakening the immune response
and increasing susceptibility to fungal invasion.
Weakened Immune System – Individuals with diabetes, circulatory disorders, or compromised immunity are
more
prone to fungal infections. Weakened immune function and poor circulation can
make infections more severe, harder to treat, and slower to heal, increasing the risk of
complications.
What Are the Symptoms of Nail Fungus?
Nail fungus symptoms develop gradually and can range from mild to severe. Common signs include:
Discolouration – Nails may turn yellow, brown, or white due to fungal
buildup and keratin degradation, often one of the earliest signs.
Thickened and Distorted Nails – The nail may become abnormally thick
and uneven as the infection disrupts growth, causing excessive keratin buildup and
structural changes.
Brittle or Crumbly Texture – The nail may break easily or develop
ragged edges as the infection weakens its structure.
Nail Detachment (Onycholysis) – The nail may
separate from the nail bed as fungal activity damages the tissue underneath, leading to
discomfort or pain.
Foul Odour – In advanced infections, the nail may emit an unpleasant
smell due to fungal overgrowth and decomposition of nail material.
If left untreated, the infection can worsen, spreading to other nails, surrounding skin, or even to others through direct or indirect contact. If you notice any of these symptoms, consult a doctor for proper diagnosis and treatment to prevent further spread and complications.

Medical Review – Assessment of medical history, underlying medical
conditions, and lifestyle factors that may contribute to fungal infections. Identifying
risk factors helps in early intervention and prevention.
Visual Examination – Inspection of the affected nail for common signs
such as discolouration, thickening, brittleness, and detachment.
Microscopic Examination – Analysis of nail clippings or debris under a
microscope using potassium hydroxide (KOH) testing to detect fungal elements.
Fungal Culture – A lab test that cultivates a nail sample to accurately
identify the fungal species. It is typically performed when initial treatments fail or
to rule out non-fungal conditions such as bacterial infections or nail psoriasis.
How to Treat Nail Fungus?
Treatment for nail fungus ranges from topical and oral medications to more advanced procedures,
depending on the severity of the infection. The choice of treatment is influenced by factors such as
prior treatment response, medical history, and patient preference.
Non-invasive treatment that aims to eliminate fungus and allow the nail to regrow
naturally.
Typically recommended for mild to moderate cases, particularly when topical
treatments have failed or oral antifungals are not suitable due to medical
conditions or side effects.
Typically recommended for severe, recurrent, or treatment-resistant cases where
conventional therapies have failed.
Enhances the effectiveness of other antifungal treatments and helps prevent further
fungal spread.

How to Prevent Nail Fungus?
Taking preventive measures can help reduce the risk of developing nail fungus and prevent
recurrence:
Keep feet clean and dry, especially between the toes.
Disinfect shoes and socks regularly to eliminate fungal spores and reduce
reinfection risk.
Trim nails properly and avoid sharing nail clippers or files to prevent fungal
transmission.
Wear moisture-wicking socks and breathable footwear to minimise moisture
buildup.
Avoid walking barefoot in public areas such as swimming pools, gyms, and
communal showers.
When Should You Seek Medical Attention for Nail Fungus?
You should seek medical attention if you suspect a nail fungus infection or if an existing
infection:
Shows no improvement with over-the-counter treatments, despite consistent use.
Worsens or spreads to other nails or surrounding skin.
Causes pain or discomfort, affecting activities like walking.
Leads to nail detachment, where the nail lifts from the nail bed, increasing
the risk of further infection.
Becomes discoloured with signs of bacterial infection, such as redness,
swelling, pus, or foul-smelling discharge.
Individuals with underlying health conditions such as diabetes, circulatory issues, or a weakened
immune system should seek medical attention as soon as symptoms appear to prevent complications.
Nail fungus cannot be cured instantly, as treatment typically takes weeks to months.
Oral antifungal medications like terbinafine or itraconazole are commonly regarded as
more effective for faster results, while topical treatments and laser therapy may also
be considered. Early diagnosis and consistent treatment can help speed up recovery. It
is advisable to consult a doctor to determine the most appropriate treatment based on
the severity of your condition.
Diabetes can increase the risk of nail fungus due to weakened immunity and reduced blood
circulation, particularly in the feet. Poor circulation makes it harder for the body to
fight infections, allowing fungi to thrive. Additionally, increased glucose levels in
sweat and skin can create a favourable environment for fungal growth. Individuals with
diabetes should monitor their nails closely and seek early treatment to prevent
complications such as secondary infections.
Nail polish itself does not cause nail fungus, but it can create an environment that
promotes fungal growth. Thick layers of polish trap moisture, providing ideal conditions
for fungi to thrive. If applied over an existing infection, it may worsen the condition
by preventing airflow and delaying treatment. Using antifungal nail polish or allowing
nails to breathe between applications can help reduce the risk. If symptoms appear,
consult a doctor for prompt diagnosis and treatment.
Nail fungus does not always cause pain, but as the infection progresses, it can lead to
thickened, brittle, or distorted nails that press against surrounding skin, causing
discomfort. Severe infections may result in inflammation, onycholysis (nail detachment),
or secondary bacterial infections, leading to pain. If nail fungus becomes painful or
interferes with daily activities, it is advisable to consult a doctor for proper
diagnosis and treatment to prevent complications.
Wearing nail polish over toenail fungus is not advised, as it can trap moisture and
worsen the infection. It may also mask symptoms, delaying diagnosis and treatment. If
coverage is necessary, antifungal nail polishes formulated with active ingredients like
ciclopirox or amorolfine can be used under medical guidance. However, allowing the nail
to breathe and following a prescribed treatment plan is essential for optimal recovery.
Consulting a doctor can help determine the best approach for your needs.
The most effective nail fungus treatment depends on the severity of the infection. Oral
antifungal medications like terbinafine and itraconazole are commonly prescribed for
moderate to severe cases. Topical treatments such as amorolfine and ciclopirox may be
used for mild infections. Laser therapy and nail removal are additional options for
resistant cases. Consulting a doctor can help determine the most suitable treatment
based on individual needs and medical history.
Healing nail fungus requires consistent treatment and patience, as complete resolution
can take several months. Oral antifungals like terbinafine or itraconazole are commonly
prescribed for systemic treatment, while topical medications work for milder cases.
Laser therapy or nail removal may be needed for persistent infections. Keeping feet dry,
trimming nails properly, and avoiding reinfection can aid recovery. Consulting a doctor
ensures an appropriate treatment plan based on the severity of the condition.
Gel nails do not directly cause fungal infections, but improper application or prolonged
wear can increase the risk. If moisture gets trapped between the gel layer and the
natural nail, fungi can grow. Over-filing or damage to the nail bed can also create
entry points for infection. To reduce risk, nails should be properly cleaned before
application, and gel polish should not be worn for extended periods without breaks. If
symptoms of an infection appear, it is important to consult a doctor for prompt
diagnosis and treatment.
Baking soda is not a proven cure for nail fungus, but it may help absorb moisture and
create an inhospitable environment for fungal growth. While some people use it as a home
remedy, there is limited scientific evidence to support its effectiveness in treating
nail fungus. Medical treatments such as topical or oral antifungal medications, laser
therapy, and nail removal are more medically recognised options. It is advisable to
consult a doctor to help determine the most appropriate treatment for your condition.
Nail fungus may grow out over time if treated effectively, but it can take many months
for a healthy nail to fully replace the infected one. Treatment helps eliminate the
fungus and prevent further spread, allowing the nail to regrow normally. However,
without treatment, the infection can persist or worsen. Maintaining proper foot hygiene
and following a prescribed treatment plan can improve recovery and reduce the risk of
recurrence. Consulting a doctor can help ensure proper management.
The cost of nail fungus treatment in Singapore depends on the treatment method. Topical
antifungal medications are generally more affordable, while oral antifungals, laser
therapy, and surgical nail removal may cost more. Prices also vary by clinic, treatment
duration, and consultation fees. Some clinics offer package pricing for laser
treatments. It is advisable to contact a medical provider for detailed pricing and to
determine the best treatment for your condition.
The duration of nail fungus treatment depends on the severity of the infection and the
treatment method used. Mild cases treated with topical antifungals may take several
months, while oral antifungal medications typically require 6 to 12 weeks, though full
nail regrowth can take longer. Laser therapy may show faster results, but the nail still
needs time to grow out. Severe infections can take a year or more. Consulting a doctor
can provide a clearer recovery timeline based on your condition.
Nail fungus can be effectively treated, but recurrence is possible if preventive
measures are not taken. Oral antifungal medications, topical treatments, laser therapy,
and nail removal can help eliminate the infection, but maintaining proper foot hygiene
and avoiding reinfection are essential for long-term results. Some individuals,
particularly those with underlying health conditions, may be more prone to recurrence.
Consulting a doctor can help determine the most appropriate treatment and prevention
plan for lasting results.
A general practitioner (GP) can diagnose and treat nail fungus by prescribing topical or
oral antifungal medications, depending on severity. They may also recommend preventive
care and lifestyle measures to reduce recurrence. At Medical Aesthetics, we offer a
range of nail fungus treatments from $18, including topical and oral medications, laser
therapy, and nail removal.
Trimming an infected toenail can help manage symptoms but will not cure the infection.
Reducing nail thickness may improve comfort and allow topical treatments to penetrate
more effectively. However, cutting too aggressively or improperly may cause injury,
worsen the infection, or lead to secondary complications. It is advisable to trim nails
carefully, maintain good hygiene, and avoid sharing nail tools. Consulting a doctor can
provide guidance on proper nail care and the most suitable treatment options.
Seeing a doctor for nail fungus is advisable, particularly if the infection persists,
worsens, or causes discomfort. While mild cases may respond to over-the-counter
antifungal treatments, moderate to severe infections often require prescription
medications or advanced therapies like laser treatment. A doctor can confirm the
diagnosis, rule out other nail conditions, and recommend an appropriate treatment plan
to manage the infection and reduce the risk of recurrence or complications.
A general practitioner (GP) with a focus on dermatology, a dermatologist, or a
podiatrist can diagnose and treat toenail fungus. The choice may depend on the severity
of the infection and any underlying health conditions. At Medical Aesthetics, we offer a
range of nail fungus treatments from $18, including topical and oral medications, laser
therapy, and nail removal. All prices are NETT and inclusive of GST.
If left untreated, toenail fungus can worsen, leading to thickened, brittle, or deformed
nails. The infection may spread to other nails, surrounding skin, or even cause
secondary bacterial infections, especially in individuals with diabetes or weakened
immune systems. In severe cases, the nail may detach, causing pain and difficulty
wearing shoes. Long-term fungal infections can be harder to treat, requiring more
intensive therapies. Consulting a doctor early can help determine the most suitable
treatment and prevent complications.
Toenail fungus can worsen due to prolonged moisture exposure, poor foot hygiene, tight
or non-breathable footwear, and underlying health conditions such as diabetes or
circulatory disorders. Nail trauma, improper trimming, or failing to complete antifungal
treatments can also contribute to persistent infections. Reinfection is possible if
preventive measures, such as disinfecting shoes and keeping feet dry, are not followed.
Consulting a doctor can help manage the condition properly and reduce the risk of
worsening or recurrence.
Wearing socks to bed with toenail fungus can help prevent the spread of fungal spores to
bedding or other toenails, but it is important to choose breathable, moisture-wicking
socks to keep feet dry. Fungal infections thrive in warm, damp environments, so wearing
socks made of natural or antibacterial fabrics may help reduce moisture buildup. Washing
socks regularly and avoiding shared footwear can further prevent reinfection. Consulting
a doctor can provide guidance on proper foot hygiene and treatment options.
