Yellow nails can be caused by a variety of factors, ranging from cosmetic habits to underlying health issues. Staining from nail polish, self-tanning products, hair dye, or smoking can cause nails to turn yellow. Additionally, fungal infections, such as onychomycosis, are a common cause of yellow nails, especially in toenails. Yellow nails can also be a symptom of underlying health conditions such as diabetes, liver disease, congestive heart failure, lung disease, certain cancers, vitamin E or D deficiency, and thyroid issues. In rare cases, yellow nail syndrome, a disorder affecting the nails, lungs, and limbs, may be the cause. If you notice persistent nail discoloration or other concerning symptoms, it is important to consult a healthcare professional for an accurate diagnosis and appropriate treatment.

What You'll Learn
Yellow nail syndrome
YNS is characterised by three main types of symptoms: nail changes, swelling, and respiratory symptoms. Nail changes include slowed or stopped nail growth, thickening, and yellow, green, or ridged discolouration. The nails may also detach from the nail bed and fall off. Swelling, or lymphedema, affects about 8 in 10 people with YNS, and usually occurs in the legs a few months after nail changes. Respiratory symptoms, including a chronic cough, repeat sinus infections (sinusitis), and pneumonia, are present in almost 2 in 5 people with YNS and are caused by fluid buildup in the lung tissue (pleural effusions).
The exact cause of YNS is unknown, and the syndrome is often misdiagnosed. However, some experts believe that it results from issues with the circulatory or lymphatic system, which can cause fluid to collect in the soft tissues under the skin, turning the nails yellow. There may also be a genetic component to YNS, with some researchers speculating that it is inherited in an autosomal dominant pattern. Other researchers have suggested a link between YNS and titanium exposure from joint replacements, dental implants, and certain medications.
Treatment for YNS is tailored to the individual's specific symptoms and suspected underlying causes. For example, if improper lymph drainage is suspected, a specialised massage may be recommended to improve circulation. Vitamin E has also been studied as a successful treatment for YNS due to its ability to stimulate healthy nail growth.

Infections
Yellow nails can be caused by fungal infections, which are straightforward to treat using oral or topical antifungal medications. However, cure rates with current antifungals are generally 50-60%, so you may need to repeat the course of treatment. Your dermatologist can culture your nails to determine the exact type of fungus and tailor the treatment accordingly. Onychomycosis, a type of fungal infection, can affect any part of the toenail and cause it to appear yellow. It can also be uncomfortable and make walking difficult.
Yellow nails can also be a symptom of yeast or bacterial infections. Vitamin E can help treat bacterial infections as it stimulates healthy nail growth and can be applied topically or taken orally.
Yellow nail syndrome is a rare condition that can cause both fingernails and toenails to turn yellow. It can also cause nail thickening, curving, and separation from the nail bed. The cause of this condition is unknown, but it may be linked to issues with the circulatory or lymphatic system, resulting in fluid collection under the skin. Some researchers believe there may be a genetic component, specifically a mutation in the FOXC2 gene. Yellow nail syndrome can also cause respiratory problems and swelling in the lower limbs.
In addition to infections, yellow nails can be caused by surface stains from nail polish, self-tanning products, or hair dye. They can also be a sign of smoking or exposure to tobacco smoke, with nails taking on a rounded or clubbed appearance.

Staining from products
Self-tanning products can also cause yellow nails if applied without gloves. The ingredient DHA in self-tanners reacts with skin cells to produce a yellow-orange color, which can accumulate around the cuticles, resulting in a dark yellow appearance on the nails. Hair dye can have a similar effect, leaving behind yellow stains when used without proper hand protection.
In most cases, nail discoloration from product staining is purely cosmetic and not harmful. The staining will usually grow out as the nails grow over time. To speed up the process, it is recommended to take a break from using nail polish, avoid acetone-based removers, and opt for non-acetone removers instead. Soaking the nails in diluted vinegar (a mixture of one part vinegar and four parts water) can also help reduce yellowing.

Vitamin deficiencies
Yellow nails can be caused by vitamin deficiencies, particularly a lack of vitamins E and D. While vitamin E deficiency does not directly cause yellow nails, it can lead to dry, brittle nails, slower nail growth, and weakened immunity, which may increase the risk of nail infections or other conditions that cause yellowing. Vitamin E is known to help cells retain moisture and look healthier. It stimulates healthy nail growth and can be applied topically or taken orally to support nail health.
Vitamin D deficiency has been linked to a condition called longitudinal melanonychia, which typically presents as black lines on the nails. However, it may also cause yellowing or other pigmentation changes in some cases.
Yellow nails can also be caused by various factors, including nail polish, smoking, fungal infections, and underlying health conditions. In some cases, yellow nails may be a symptom of more serious health issues, such as chronic lung conditions, internal malignancies, lymphatic obstructions, or rheumatoid arthritis.
To address vitamin E and D deficiencies, it is important to maintain a balanced diet rich in vitamin E and vitamin D sources or consider taking supplements under the guidance of a healthcare professional. Additionally, avoiding nail polish, stopping smoking, maintaining proper nail hygiene, and seeking medical advice for persistent or concerning symptoms are recommended to improve nail health and address yellowing.

Underlying health conditions
Yellow nails can be indicative of underlying health conditions, which may be serious. It is important to visit a doctor if you are concerned about the colour of your nails, especially if the discolouration persists or is accompanied by other symptoms.
Yellow nail syndrome is a rare condition that can cause nails to turn yellow and thicken, curve, slow or stop growing, and separate from the nail bed. It can also cause fluid buildup and swelling in the lower limbs, and respiratory problems. The cause of the condition is unknown, but it may be linked to issues with the circulatory or lymphatic system, genetics, or exposure to titanium.
Yellow nails can also be a sign of chronic lung conditions, internal malignancies, lymphatic obstructions, and rheumatoid arthritis. Discolouration can be caused by fungal infections, which are straightforward to treat with oral or topical antifungal medication. However, cure rates with current antifungals are generally 50-60%, so repeated treatment may be necessary.
In people with diabetes, around 40% experience a yellow tint to their nails, and they are also more prone to fungal nail infections. Psoriasis is a skin condition that can cause nail discolouration and pitting. Liver disease causes a buildup of bilirubin, which may tint nails yellow. Congestive heart failure can reduce blood flow to extremities, impacting nail health and colour. Certain cancers can impact the body's metabolism and immune response, leading to discolouration and an increased risk of infections.
Vitamin E deficiency does not directly cause yellow nails, but it can lead to slower nail growth and weakened immunity, increasing the risk of nail infections or other conditions that cause yellowing. Similarly, vitamin D deficiency has been linked to nail changes and discolouration.
