Toenail fungus is a common condition that can cause a strong odour, sometimes likened to cheese. The smell is caused by the organism tinea unguium, a type of bacteria called Brevibacterium, which is also used to mature certain cheeses. This bacteria thrives in dark, moist environments, such as sweaty shoes, and can cause toenail discolouration, thickness, and brittleness. The fungus usually enters the toenail through a crack, cut, or bruise, and can be challenging to treat once it spreads. Good foot hygiene, including regular washing and drying, is key to preventing and treating toenail fungus.

Toenail fungus, or Onychomycosis, is a common cause of toenail odour
Toenail odour is often caused by a fungal infection known as onychomycosis, which affects the toenails more often than the fingernails. This is due to the slower growth of toenails, their reduced blood supply, and the frequent confinement in dark, moist environments. Onychomycosis is caused by various organisms, most commonly dermatophytes of the genus Trichophyton, which can enter the toenail via a crack, cut, or bruise. Other causative organisms include Candida, which is more commonly found in fingernail infections, and nondermatophyte molds such as Fusarium, Aspergillus, and Acremonium.
The infection causes the nail to thicken and discolour, ranging from white to yellowish, brown, or black. It can also lead to streaking within the nail and lifting of the nail from the nail bed. The smell associated with onychomycosis often originates from the soft, sticky mash underneath the nail, which can have a creamy-yellow or greenish-black discolouration.
Onychomycosis is a common condition, with a prevalence of 10% in the general population and increasing to 50% in individuals over 70 years old. It is more common in older adults due to factors such as peripheral vascular disease, immunologic disorders, and diabetes mellitus. Additionally, individuals with distorted nails, a history of nail trauma, genetic predisposition, hyperhidrosis, concurrent fungal infections, or psoriasis are at an increased risk of developing onychomycosis.
The treatment for onychomycosis typically involves antifungal medications, such as oral azole and allylamine drugs, or topical agents applied directly to the nail. However, it is important to obtain an accurate diagnosis through physical examination and laboratory analysis before initiating treatment. Treatment can be lengthy, often taking months or years to see improvements, and recurrence rates are high, ranging from 5% to 50%. Therefore, prompt commencement of treatment and follow-ups are essential for successful management of the condition.

The organism Tinea unguinum causes the cheesy smell
Toenail fungus, or onychomycosis, is a common infection that can be challenging to treat. It is caused by an organism known as Tinea unguinum, a type of mold called a dermatophyte that feeds on keratin, the protein that gives nails their hardness. This fungus typically enters through cracks, cuts, or bruises on the toenail or surrounding skin, and it thrives in warm, moist environments, such as sweaty shoes or boots. While Tinea unguinum usually affects toenails, it can also infect fingernails.
The presence of Tinea unguinum can lead to several unsightly symptoms. The nail may thicken and develop a yellow or white discolouration, with spots and streaks. In more severe cases, the nail can lift from the nail bed, and a soft, sticky substance may accumulate underneath, giving off a distinct cheesy odour. This smell is often described as unpleasant and offensive, causing embarrassment and self-consciousness.
The fungus thrives in environments rich in keratin, which is abundant in the nails. As the fungus feeds and spreads, it can cause further discolouration and textural changes to the nail. The warm, moist conditions created by sweaty feet and non-breathable shoes provide an ideal environment for the fungus to flourish, exacerbating the problem.
While Tinea unguinum itself does not cause pain, the infection can lead to discomfort and emotional distress due to the unpleasant odour and the unsightly appearance of the nail. Left untreated, the fungus can spread and lead to more serious health complications. Therefore, it is essential to maintain good foot hygiene and seek treatment options, such as oral or topical antifungal medications, to eradicate the infection.
To summarise, the organism Tinea unguinum, a type of dermatophyte mold, is responsible for causing toenail fungus, which can result in a cheesy smell. The fungus feeds on keratin in the nails, leading to discolouration, thickening, and odour. Maintaining good foot hygiene and seeking appropriate treatment are crucial to address this common yet challenging condition.

Fungi thrive in dark, damp environments, like sweaty shoes
Fungi, the plural of fungus, are microscopic organisms that thrive in damp, warm, and dark environments. Fungi can enter your toenail through a crack, cut, or bruise on your toenail or the skin near it. They can also enter through the pooling of blood under the nail, which breaks the seal between the nail and its bed.
Fungus thrives in sweaty shoes and socks, which add to the dampness and warmth that fungi need to grow and spread. This is why it is important to wear well-ventilated shoes and socks that do not trap moisture. Cotton or wool socks are good choices, as are shoes with small holes to keep the feet dry. Changing your socks regularly, especially if your feet sweat a lot, and regularly washing your socks, bedsheets, and towels can also help prevent fungal growth.
Fungal nail infections are common, with around 14% of the population affected in the United States. Toenail fungus is more likely to occur in people over 70, with up to 50% of people in this age group affected. It is more common in toenails than fingernails because toenails are often kept in warm and moist environments, like sweaty shoes, providing the perfect breeding ground for fungi to take root and spread.
Fungal nail infections can cause an unpleasant smell and lead to discolouration of the nail, such as white to yellowish, brown, or black. The nail may also become crumbly and lift from the nail bed. If left untreated, toenail fungus could lead to more serious health conditions. Therefore, it is important to practice good foot hygiene and seek treatment if necessary.

Foot hygiene and footwear choices can impact toenail odour
The type of shoes worn also plays a significant role in toenail odour. Wearing non-breathable shoes that trap moisture can create an ideal environment for fungal growth. Opting for breathable footwear that allows adequate air circulation can help reduce the likelihood of developing toenail odour issues. It is also recommended to avoid walking barefoot in public places, such as swimming pools, showers, or gym locker rooms, as these environments can expose the feet to fungal infections.
While foot hygiene and footwear choices are essential, other factors come into play as well. Trimming toenails too short or having overly rounded or V-shaped toenails can increase the risk of ingrown toenails, making individuals more susceptible to bacterial and fungal infections. Therefore, it is advisable to trim toenails in a straight line, ensuring the corners align comfortably with the skin. Additionally, long toenails can harbour dirt and debris, contributing to odour and providing a breeding ground for bacteria and fungi.
Furthermore, certain medical conditions can also influence toenail odour. For example, individuals with poor circulation or diabetes may be more prone to recurrent skin and nail infections, potentially leading to persistent toenail odour issues. In such cases, consulting a healthcare professional is advisable to receive appropriate treatment and manage the underlying condition effectively.
If the toenail odour persists or is accompanied by other symptoms, it is recommended to consult a podiatrist or healthcare professional. They can accurately diagnose the cause of the odour and provide tailored treatment options, such as antifungal medications or laser therapy, to address the issue effectively.

A podiatrist can diagnose and treat toenail fungus with laser treatment
Toenail fungus is a common condition, affecting around 14% of people in the United States, and it tends to be more prevalent in older individuals with weakened immune systems. It occurs when a fungus enters the toenail through a crack, cut, or bruise on the toenail or the surrounding skin. The fungus causes an infection that can lead to discoloration, thickening, and crumbling of the toenails, often accompanied by discomfort and pain.
The infection can result in an offensive smell, discolouration, and other unsightly changes to the nail's appearance. If you notice any of these signs, it is advisable to consult a podiatrist for an evaluation. A podiatrist can accurately diagnose toenail fungus by examining the physical appearance of the nail and requesting a laboratory test, such as a mycology test, for confirmation.
Traditional treatments for toenail fungus include topical antifungal creams, oral medications, and surgical interventions. However, these methods often have limitations, such as suboptimal efficacy, adverse side effects, or invasive procedures with prolonged recovery periods. As a result, many individuals are left dissatisfied with the available treatment options.
Fortunately, podiatrists now have laser therapy as a safe, effective, and non-invasive treatment option for toenail fungus. Laser therapy devices emit specific wavelengths of light that penetrate the nail and target the fungal cells, disrupting their metabolic processes and structural integrity. This thermal effect eradicates the fungus while promoting healthy nail tissue growth.
With multiple sessions spaced over several weeks, laser therapy achieves gradual but significant improvement in nail appearance and health. It is a convenient treatment option with no downtime, allowing individuals to resume their normal daily activities immediately. The procedure is generally painless, with no known side effects, and is safe for individuals of all ages.
