Fungal infections
Toenail fungus, also known as onychomycosis, is a common cause of white spots on toenails. It typically presents as a white or yellow-brown spot under the tip or side of the toenail. If left untreated, the infection can spread deeper into the nail, causing discoloration, thick white stuff under the toenail (keratin debris), nail thickening and crumbling, and even transmission to surrounding nails. The infection can also spread to the skin between the toes, a condition commonly known as athlete's foot (tinea pedis).
If you suspect you have a toenail fungal infection, it is important to see a podiatrist for diagnosis and treatment as soon as possible. Mild cases may resolve on their own, but if the infection progresses, it can lead to complications such as swelling, pain, and bleeding around the nails, difficulty walking, or more serious infections, especially in individuals with diabetes or weakened immune systems.
Toenail fungus is often caused by the same fungi that cause athlete's foot. These fungi thrive in warm, moist environments, such as sweaty shoes or damp floors in locker rooms, public showers, or swimming pools. The infection can be spread through direct contact with infected individuals or by touching surfaces contaminated with the fungi.
To prevent toenail fungus, it is important to maintain good foot hygiene, keep your feet clean and dry, wear shoes that fit properly and allow your feet to breathe, and avoid walking barefoot in public places. If you are prone to sweaty feet, using antifungal powders or sprays can help keep the feet dry and reduce the risk of infection.
There are several treatment options available for toenail fungus, including topical antifungal medications, oral antifungal medications, and nail debridement (removal of the infected nail). Your podiatrist will determine the most appropriate treatment based on the severity of the infection and your overall health. It is important to follow the recommended treatment plan to ensure the infection is effectively treated and to prevent recurrence.

Mineral deficiencies
White toenails can be caused by a mineral deficiency, such as iron deficiency anaemia or zinc deficiency. Both of these deficiencies can cause white nails that are thin and brittle. However, you will typically notice other symptoms of an iron or zinc deficiency before you see a white nail. If you suspect you have a mineral deficiency, it's important to see a medical professional. Self-treating a perceived deficiency with mineral supplements can be detrimental to your health and can even lead to a dangerous overdose.
There are several ways to treat mineral deficiencies. Increasing your intake of foods rich in the deficient mineral is often recommended. For example, if you are deficient in iron, eating more red meat, spinach, and beans can help. If you are deficient in zinc, oysters, crab, and beef are good sources. Taking mineral supplements may also be recommended, but it is important to consult a healthcare professional before taking any supplements to avoid the risk of overdose.
In addition to dietary changes and supplements, there are other treatments for mineral deficiencies. For example, if you have iron deficiency anaemia due to blood loss, you may need to address the underlying cause of the blood loss. If you have a zinc deficiency due to malabsorption, you may need to treat the underlying condition causing the malabsorption. In some cases, intravenous (IV) mineral replacement therapy may be necessary.
It is important to note that white toenails can also be caused by other factors, such as nail fungus or overuse of toenail polish. If you are experiencing white spots or discolouration on your toenails, it is always best to consult a healthcare professional for proper diagnosis and treatment.

Psoriasis
White toenails can be caused by a mineral deficiency, nail fungus, or overuse of toenail polish. If most of the toenail appears white, except for the tip, it could be a sign of an iron or zinc deficiency. However, you will typically notice other symptoms of these deficiencies before you see a white nail. Toenail fungus, or onychomycosis, is another common cause of white toenails. It typically presents as a white or yellow-brown spot under the tip or side of the toenail, and if left untreated, it can cause the nail to thicken and crumble. Overuse of toenail polish can also lead to white, chalky toenails due to the formation of keratin granulations on the surface of the nail.

Nail dehydration
White toenails can be caused by a number of factors. One of the most common causes is a fungal infection, known as onychomycosis. This can cause white spots under the tip or side of the toenail, and if left untreated, can spread deeper into the nail, causing thick white keratin debris to build up under the nail, thickening and crumbling of the nail, and even transmission to surrounding nails. It can also spread to the skin between the toes, causing athlete's foot. If you suspect a fungal infection, it is important to see a podiatrist for diagnosis and treatment as soon as possible to prevent complications such as swelling, pain, and bleeding around the nails.
Another possible cause of white toenails is nail dehydration. This is often the result of prolonged use of nail polish and acetone-based nail polish removers, which can dry out the surface of the toenails. This leads to the formation of keratin granulations, which are dehydrated superficial layers of nail cells that cause white, rough, and uneven dry patches on the top of the nail. To treat nail dehydration, it is recommended to take a break from nail polish and rehydrate the nails.
In some cases, white toenails may be a sign of a mineral deficiency, such as iron deficiency anemia or zinc deficiency. These deficiencies can cause the nails to become thin, brittle, and discoloured. However, it is important to note that other symptoms of these deficiencies are typically noticed before nail discolouration. If you suspect a mineral deficiency, it is recommended to consult a medical professional for proper diagnosis and treatment. Self-treating with mineral supplements without proper guidance can be detrimental to your health and may lead to an overdose.
Additionally, white toenails with red stripes may indicate underlying health issues elsewhere in the body. In rare cases, white toenails can also be a sign of proximal subungual onychomycosis, a type of fungal infection that occurs in people with weakened immune systems or HIV. Therefore, if you notice any discolouration or changes in your toenails, it is always best to consult a healthcare professional for a proper diagnosis and appropriate treatment.

Leukonychia
White toenails can be caused by a number of factors. One of the most common causes is a mineral deficiency, such as iron deficiency anaemia or zinc deficiency, which can cause nails to become thin and brittle. However, it is important to note that you will typically notice other symptoms of a mineral deficiency before you see a white nail. Another common cause of white spots on toenails is nail fungus, which can cause the nail to become discoloured, thick and crumbly. This condition is officially called onychomycosis and can be treated by a podiatrist.
If you are a frequent user of toenail polish, white spots on your toenails may be the result of keratin granulations. These are dehydrated superficial layers of nail cells that result in white, rough and uneven dry patches on the top of the nail. Prolonged use of nail polish and acetone-based nail polish removers can dry out the surface of your toenails and lead to keratin granulations. If left untreated, these spots can develop into a fungal infection.
It is important to see a medical professional if you suspect you have a mineral deficiency or a fungal infection. While it may seem tempting to self-treat a perceived deficiency with mineral supplements, this can be detrimental to your health and can even lead to a dangerous overdose. Therefore, it is always best to seek professional advice before starting any treatment.
In rare cases, white toenails can be a sign of a more serious underlying health condition. For example, proximal subungual onychomycosis, a type of fungal infection that presents as a whitish or yellowish patch at the base of the toenail, can be a sign of a weakened immune system or even HIV. Therefore, it is important to pay attention to any changes in your toenails and seek medical advice if you are concerned.
