What You'll Learn
Yellow toe nails can be caused by nail polish
Yellow toenails can be caused by a number of factors, one of which is nail polish. While yellowing of the toenails can be harmless, it can also be a sign of a more serious underlying health condition. Therefore, it is important to identify the cause of the discolouration.
Nail polish can cause toenails to become discoloured and take on a yellow hue. This is due to the pigments and chemicals used in the polish. The yellowing may also occur due to a reaction between the polish and the natural oils on the toenails, or from prolonged exposure to the chemicals in the polish. Darker colours, such as red, orange, black, and blue, are more likely to stain the toenails and leave behind a yellow tint. This is because the pigments sometimes react with the top layer of the nail plate, creating a yellow stain.
To prevent nail polish from turning your toenails yellow, it is recommended to use a base coat to create a barrier between the nail and the polish. It is also important to let your nails breathe by taking breaks from nail polish. Additionally, choosing high-quality nail polishes can reduce the likelihood of yellowing. It is also recommended to avoid shaking the nail polish bottle, as this can cause air bubbles that may lead to yellowing. Instead, the bottle should be rolled between the palms to mix the polish.
If your toenails have turned yellow due to nail polish, simply removing the polish and letting your nails breathe for a few days should cause the discolouration to fade. In some cases, a nail stain remover or whitening toothpaste that contains peroxide can be used to remove the stain.

A fungal infection can cause yellow toe nails
Yellow toenails are often caused by a fungal infection. Fungi thrive in warm, damp environments, and toenails provide these conditions when encased in socks and shoes. This is especially true if the shoes are tight-fitting or ill-fitting, as this can worsen the discolouration. People who spend a lot of time in moist conditions, such as athletes or those who frequent swimming pools, are more prone to toenail fungus.
Toenail fungus is typically treatable with antifungal medication, which comes in both topical and oral forms. However, cure rates with current antifungals are generally only 50-60%, so you may need to repeat the course of treatment. There are also some home remedies that may help, such as tea tree oil, Vicks VapoRub, and soaking the affected nail in hot water mixed with baking soda.
Yellow toenails can also be caused by excessive nail polish use, particularly red, orange, or yellow polishes. This type of discolouration is harmless and will grow out over time. To speed up the process, avoid nail polish and acetone nail polish removers, and soak your nails in diluted vinegar (one part vinegar, four parts water).
In some cases, yellow toenails can indicate a more serious underlying health condition. One such condition is yellow nail syndrome, a rare disorder characterised by yellow toenails and fingernails, along with respiratory problems and swelling of the lower limbs. Experts do not know exactly what causes yellow nail syndrome, but it may be linked to issues with the circulatory or lymphatic system. Another potential underlying cause of yellow toenails is diabetes, as this can weaken the immune system and make people more susceptible to infection.

Underlying medical conditions can be the cause of yellow toe nails
Yellow toenails can be caused by several factors, including fungal infections, natural ageing, and overuse of nail polish. However, in some cases, yellow toenails can indicate underlying medical conditions that require attention.
One such condition is yellow nail syndrome (YNS), a rare disorder characterised by yellow, curved, thickened nails that grow slowly. YNS can also cause respiratory problems, swelling of the lower limbs, and nail ridges or indentations. While the exact cause of YNS is unknown, it may be linked to issues with the circulatory or lymphatic system, leading to fluid buildup under the skin. People with autoimmune diseases, dental implants, or joint replacements may have a higher risk of developing YNS.
Diabetes is another potential underlying cause of yellow toenails. This can occur due to a weakened immune system, making individuals more susceptible to infections, or as a result of sugar breakdown and its effect on collagen in nail tissue. Peripheral vascular disease and other autoimmune disorders can also contribute to yellow toenails by affecting blood circulation in the legs.
Additionally, yellow toenails can be associated with other medical issues such as tuberculosis (a lung infection), bronchiectasis (damaged airways), and jaundice (liver disease). These conditions may indicate a more serious issue, especially when accompanied by other symptoms. Therefore, it is important to consult a doctor if you notice persistent yellowing of the toenails or any accompanying symptoms.
While yellow toenails can be a cosmetic concern, it is essential to consider the possibility of underlying medical conditions. Consulting a healthcare professional is crucial to obtaining an accurate diagnosis and receiving appropriate treatment.

Yellow nail syndrome can cause yellow toe nails
Yellow nail syndrome (YNS) is a rare disorder that can cause yellow toenails. It is characterised by slow-growing, yellow, thickened nails, lymphedema, and respiratory tract involvement. The exact cause of YNS is unknown, but it is believed to be linked to improper circulation, issues with lymphatic drainage, or fluid buildup around the lungs.
The characteristic findings associated with YNS include the development of yellow, thickened, and excessively curved nails, with almost complete stoppage of nail growth. The nails may also have ridges or indentations and can turn black or green. YNS can also cause the loss of the cuticle, the strip of hardened skin at the base and sides of the nail.
In addition to nail changes, individuals with YNS often experience swelling of the arms and legs due to the accumulation of a protein-rich fluid called lymph (peripheral) lymphedema. The legs are especially affected, with decreased flexibility and tightness in the hands, feet, wrists, or ankles.
Respiratory symptoms are also common in YNS, with almost 2 in 5 people experiencing fluid buildup in the lung tissue (pleural effusions). This can lead to shortness of breath, chest pain, and a chronic cough. Other respiratory problems associated with YNS include chronic infection, inflammation of the bronchial tubes (bronchitis), and destruction and widening of the small air passages (bronchiectasis).
While YNS is a rare disorder, it is important to see a doctor if you suspect you have this condition. Treatment options are limited, and early identification of the triad of symptoms (yellow nails, lymphedema, and pulmonary disease) is crucial for effective management.

Yellow toe nails can be caused by ageing
Yellow toenails are often caused by fungal infections, overuse of nail polish, or an underlying medical condition. However, it is important to note that ageing can also play a role in the discolouration of toenails. As people grow older, the colour, thickness, and shape of their nails tend to change. Ageing individuals might notice that their nails become thicker and take on a more yellow hue. This change in nail colour can be a natural consequence of the ageing process, including both diminished blood flow and toenails becoming thicker. Combined, these factors can lead to a yellow coloration.
While yellow toenails due to ageing are typically harmless, it is important to be aware of potential underlying causes that may require medical attention. In some cases, yellow toenails can indicate an infection, such as onychomycosis, which is caused by a fungus that attacks the nails. This condition is more common in adults than children and can cause discomfort and difficulty in walking. Therefore, it is advisable to monitor your nails regularly for any changes and seek medical advice if concerned.
Fungal infections, which are a common cause of yellow toenails, thrive in warm and damp environments. Wearing shoes and socks that do not allow your feet to breathe, or frequently walking barefoot in places like pool decks, locker rooms, and showering areas, can increase the risk of fungal infections. Practising good foot hygiene, keeping your toes clean, and ensuring your toenails are dry can help prevent fungal infections.
In addition to ageing and fungal infections, yellow toenails can also be caused by certain nail polishes, especially those in red, orange, or yellow shades. Discolouration from nail polish is typically harmless and can be remedied by taking a break from painting your nails. However, if the discolouration is due to an underlying medical condition, other symptoms may be present. These underlying conditions may include diabetes, peripheral vascular disease, autoimmune disorders, or, in rare cases, yellow nail syndrome (YNS).
Yellow nail syndrome is a rare genetic disorder that can occur in conjunction with lymphoedema, a blockage in the lymphatic system. While the exact cause of YNS is still unknown, individuals with this condition exhibit yellow, curved, thickened nails that grow slowly and may have ridges or indentations. Respiratory problems and swelling of the lower limbs are also associated with YNS. Therefore, if you suspect an underlying medical condition or notice additional symptoms, it is important to consult a doctor for proper diagnosis and treatment.

Frequently asked questions
A yellow toenail is usually caused by a fungal infection, but it can also be caused by excessive nail polish use, diabetes, or an underlying medical condition.
A fungal infection can cause the toenail to become white, yellow, or brown. Over time, debris builds up beneath the nail, causing it to darken. Nails can grow brittle, crumbly, or ragged.
There are several home remedies for treating a fungal infection in the toenail, including:
- Soaking the affected nail in hot water mixed with baking soda or vinegar and water
- Applying tea tree oil, olive leaf extract, or coconut oil to the affected nail
- Soaking the feet in warm salt water
- Trimming toenails and smoothing the edges with a file
- Over-the-counter antifungal nail creams and ointments
Yellow nail syndrome is a rare condition that can cause both fingernails and toenails to turn yellow. The nails may also grow more slowly, lack a cuticle, and damage easily. Other symptoms include respiratory problems and swelling of the lower limbs.
There is currently no effective treatment for yellow nail syndrome. Treatment is focused on addressing the systemic symptoms, such as respiratory problems and peripheral edema.
