Black nail fungus is a condition that can be caused by a number of factors, including repetitive trauma, underlying health conditions, and fungal infections. It is especially common in runners, skiers, and people who wear tight shoes or boots. Black nail fungus can also be a sign of more serious conditions, such as melanoma or diabetes. It is important to see a podiatrist if you notice your toenail is black or turning black, as it may be a symptom of a fungal infection or something more serious.

What You'll Learn
Trauma to the nail
If you notice that your toenail is turning black, it is important to see a podiatrist. They can determine if the discolouration is due to trauma, a fungal infection, or a more serious condition such as melanoma or diabetes. A nail sample or biopsy may be necessary to confirm the diagnosis.
In addition to trauma, fungal infections, and underlying health conditions, black toenails can also be caused by certain lifestyle factors. For example, people who live in cold climates and wear socks and shoes most of the year are more susceptible to fungal infections. Cotton socks, in particular, can keep feet slightly damp, providing an ideal environment for fungi to thrive.

Underlying health conditions
Black nail fungus can be caused by underlying health conditions, such as diabetes, peripheral vascular disease, or other conditions that affect circulation. Poor circulation can lead to changes in nail colour, while peripheral arterial disease can cause discolouration due to poor blood flow to the foot.
In addition to underlying health conditions, black nail fungus can also be caused by repetitive trauma to the toe, such as from running, skiing, or wearing tight shoes. It is important to see a podiatrist if you notice your toenail is black or turning black, as it could be a sign of onychomycosis or fungal toenails.

Toenail fungus
When toenail fungus occurs, the nail may not always turn black. It can also take on other colours, such as brown, yellow, green, or even overly white. In addition to discolouration, the texture of the nail may change, becoming thick and hard to trim or brittle and crumbly. The shape of the nail may also be affected, appearing unnatural.
It is important to note that a black toenail can sometimes be a sign of a more serious condition, such as melanoma or skin cancer. Therefore, if you notice any changes in your toenail colour or texture, it is recommended to consult a healthcare professional for proper diagnosis and treatment.
To prevent toenail fungus, it is advisable to maintain good foot hygiene, keep your feet dry, and wear well-fitting shoes that provide adequate ventilation.

Melanoma
Black nail fungus is not limited to runners, but also affects people with diabetes, peripheral vascular disease, or other conditions that affect circulation. The symptoms of a fungal infection go beyond an aesthetic change in the toenail. The toenail may not always turn black. It can turn brown, yellow, or green. It can also do the opposite and lead to overly white toenails. Frequently, the nail’s texture will change, becoming thick and hard to trim. Or, it may become brittle and crumble easily. Similarly, the shape of the nail may change entirely and become unnatural.
If you are experiencing black nail fungus, it is important to seek treatment from a qualified healthcare professional. Do not ignore the problem, as it can lead to more serious complications. Treatment options for black nail fungus may include medication, laser therapy, or surgical removal of the affected nail.

Peripheral arterial disease
While black toenails can be a sign of PAD, they can also be caused by other factors, such as trauma to the toe or fungal infections. It is important to see a podiatrist if you notice your toenails turning black, as it could be a sign of an underlying health condition.
The symptoms of PAD include pain or cramping in the legs during exercise, slow-healing wounds on the feet or legs, and shiny, smooth, hairless skin on the legs. People with PAD may also experience a decrease in the temperature of their lower legs or feet, as well as discolouration of the toenails.
If you are experiencing any of the symptoms of PAD, it is important to see a doctor as soon as possible. Treatment for PAD typically involves lifestyle changes, such as quitting smoking, eating a healthy diet, and exercising regularly. In some cases, medication or surgery may be necessary to improve blood flow to the affected area.
