What Causes Fungal Nail Infection? Treatment, Symptoms & More

Are your nails looking brittle and discoloured? Do they keep splitting and crumbling?

If so, you might probably have something called a fungal nail infection.

Fungal nail infections are a common condition that mostly affects your toenails. Although they are harmless and do not typically cause pain, you need to be rigorous in your treatment to bring back a healthy nail.

If you're showing symptoms or are simply curious, read on to find out more about fungal nail infections!


What are the Symptoms of Fungal Nail Infections?

You can spot a fungal nail infection easily by its appearance. Here are some symptoms to look out for:

  • Thickened nails

  • Discoloured nails

  • Brittle or crumbly looking

  • The nail is separated from the nail bed

  • Emits a smelly odour


What Causes Fungal Nail Infections?

toenail fungal infection

Fungal nail infection is caused by the growth of fungi within, on or under the nail. Fungi thrive in warmer environments (like Singapore) as opposed to colder ones.

It comes from the same type of fungus that causes athlete's foot or ringworm. You can also contract a fungal nail infection from someone that already has it.

Although you can avoid getting fungal infections, there are certain risk factors that increase your likelihood of contracting one.

Frequent use of nail polish or artificial nails

causes of fungal nail infection

When nail polish or fake nails are applied incorrectly, it can trap moisture and warmth, which fosters the growth of fungi.

Furthermore, if you use nail polish when you already have fungal nails, the fungi can grow in the bottle and cause future infections.

If you like to get your nails done at the nail salon, you are not entirely risk-free either.

Nail fungus can spread easily from customer to customer if the nail equipment is improperly cleaned between appointments. So be sure that the establishment you visit is hygienic and regularly disinfects its equipment!

Injuries to the nail plate or surrounding skin

certain health conditions can increase your chances of nail fungus

Nail injuries can expose the nail bed to nail fungus. If the nail injury is not adequately cleaned and dried, the fungi may have the perfect conditions to flourish.

If the area near your toenail is wounded and needs to be bandaged, it can also create the warm, moist environment nail fungus loves.

Weakened immune system

When an individual's immune system is compromised, their body is less effective at fending off pathogens like fungus.

This leads to a higher risk of severe cases of infection and a longer period of recovery.

Your immune system may be compromised due to

  • diabetes

  • peripheral arterial disease

  • cancer

  • old age

  • other chronic diseases

If you have one or more of the factors above, you should take even greater care of your nails to prevent fungal infections!


What are the Treatment Options for Infected Nails?

In some minor cases, you can treat nail fungus with home remedies like:

  • Wiping hydrogen peroxide on the infected nail(s)

  • Applying tea tree oil to the affected nail(s)

  • Soaking your feet in black tea

However, most fungal nail infections should be addressed by a podiatrist for effective treatment!

Home treatments might not sufficiently eradicate the fungal infection, which can spread quickly and cause permanent damage to the nails.

Antifungal treatments

antifungal tablets for nail fungus

Once they have confirmed your condition, it is likely that they will prescribe you stronger antifungal medicines instead of over-the-counter (OTC) ones, such as oral medication and topical creams or solutions.

Depending on the severity of your case, you will have to strictly keep to these treatments for several months or longer.

PACTMED Photodynamic Therapy (PDT)

PDT is a low-risk, non-invasive treatment for nail fungus.

Firstly, your podiatrist will apply a photosensitizing chemical to infected nails. Then, it is exposed to a specific wavelength of light from the PactMED LED, activating the chemical.

The photosensitizing chemical triggers oxygen molecules to attack and kill the fungus without affecting the surrounding tissue.

PDT is Dr Foot's preferred toenail fungus treatment as

  • there are virtually no contraindications or side effects,

  • it can effectively treat a nail infection in 3-4 sessions,

  • it is a better alternative for patients who may experience adverse side effects associated with pharmacotherapy,

  • it reduces the chances of reinfection,

  • and it promotes tissue regeneration and collagen growth!

Surgical removal

Usually, infected nails do not need to be fully removed. However, if the the infection is severe or painful and other treatments have failed, it may be advised to do so.

If your nail is surgically removed, a new nail should eventually grow in its place, but the full growth can take a year or longer.


How Can I Avoid Fungal Nail Infections?
