Yellow nails are usually caused by nail polish, fungal infections, smoking, medications, health conditions, and dyes from self-tanner. In some cases, vitamin or mineral deficiencies can also cause nails to turn yellow. Yellow nail syndrome is a rare but serious disorder that causes nail discolouration and is associated with autoimmune diseases, lymphatic diseases, and cancers. Finding the cause of yellow nails is crucial for effective treatment and maintaining nail health.

What You'll Learn
Yellow nail syndrome
YNS is characterised by slow-growing, yellow, thickened nails, lymphedema, and respiratory tract involvement. It primarily affects adults over 50, but it has also been documented in children. The nails become yellow, curved, and thickened, and may detach from the nail bed and fall off. This syndrome can also cause fluid buildup and swelling in the lower legs, with the legs being especially affected.
The respiratory symptoms associated with YNS include fluid buildup in the lung tissue (pleural effusions), chronic cough, sinus infections, and pneumonia. Almost 2 in 5 people with YNS experience these respiratory issues. Additionally, YNS can cause swelling or puffiness in different parts of the body due to the accumulation of protein-rich fluid (lymph) in the soft layers of tissue under the skin, known as lymphedema.
The cause of YNS is unknown, and experts believe it may be linked to improper circulation or issues with lymphatic drainage. Some researchers also suggest a genetic link, specifically a mutation in the FOXC2 gene, which is also associated with lymphedema-distichiasis syndrome, a condition with similar symptoms to YNS. There may also be a connection between YNS and titanium exposure from joint replacements, dental implants, and certain medications.
Treatment for YNS focuses on symptom relief and addressing associated conditions. Vitamin E supplements have been clinically studied as a successful treatment for YNS due to their ability to stimulate healthy nail growth. Antibiotics and corticosteroids may also be prescribed.

Staining from nail polish
To prevent nail polish staining, you can follow these tips:
- Use a base coat: Applying a base coat before your nail polish can create a barrier between your nails and the polish, preventing discoloration.
- Let your nails breathe: It is important to give your nails a break from nail polish and allow them to breathe. Leaving nail polish on for too long can cause yellowing. Remove the polish after a week and let your nails breathe for a few days before applying a new coat.
- Choose high-quality nail polish: High-quality nail polishes are less likely to cause yellowing than lower-quality ones.
- Avoid shaking your nail polish: Shaking the nail polish bottle can cause air bubbles, which can lead to yellowing. Instead, roll the bottle between your palms to mix the polish.
- Don't use old or expired nail polish: Old or expired nail polish can become thick and difficult to apply evenly, and it can also contribute to yellowing.
- Use Vitamin E: Vitamin E is a natural moisturizer that helps prevent dry and brittle nails. It can also promote nail growth and repair damaged nails.
If your nails have already been stained by nail polish, you can try using a nail stain remover, or soaking your nails in a vinegar solution or whitening toothpaste.

Fungal infections
Yellow nails are a common issue with many possible causes. One of the most prevalent causes is a fungal infection, which can be treated with a variety of methods.
Fungal nail infections are stubborn and challenging to treat, so early diagnosis and treatment are crucial. The fungus invades one or more nails, eating keratin, a protein found in nails, skin, and hair. Initially, the top part of the nail turns yellow, but as the infection progresses, the entire nail can change colour, becoming thick and cracked. Nail fungus is easy to pick up, and it can live on other parts of the skin, hair, and objects such as manicure tools, nail clippers, and scissors. Therefore, it is essential to be cautious when visiting nail salons and ensure that tools are sterilised or bring your own set.
To treat nail fungus, several options are available. Topical antifungal medications can be applied directly to the nails, or oral antifungals can be taken by mouth. Oral prescriptions such as terbinafine (Lamisil) or itraconazole (Sporanox) are effective against yeast and bacterial infections but have potential liver risks with long-term use. Home remedies include tea tree or oregano oil mixed with a carrier oil, soaking nails in hot water with baking soda, and improving nail hygiene by trimming nails, using a nail brush, and wearing fresh socks.
While nail fungus is a common cause of yellow nails, it is important to be mindful of other potential causes, such as staining from nail polish, medications, smoking, or more serious underlying health conditions. If home remedies are ineffective, it is recommended to consult a doctor or dermatologist to determine the underlying cause and receive appropriate treatment.

Smoking
The yellowing of nails due to smoking is referred to as the "nicotine sign" and can indicate the presence of underlying health issues. In some cases, it may be a sign of lung cancer or chronic lung disease. Additionally, smokers may experience changes in the morphology, structure, and growth characteristics of their nails, which can further reinforce the visual indication of their smoking habits.
The degree of yellowing on the nails can vary depending on smoking habits and other factors. Deeper puffs on cigarettes can result in higher tar deposition, increasing the discolouration and posing greater health risks. Behavioural and environmental factors may also influence the development of stains. For example, a smoker who frequently washes their hands may experience reduced discolouration compared to someone who does not.
While the yellowing of nails may be aesthetically undesirable, it is important to note that it is not a dangerous condition in itself. However, it can serve as a visible marker of potential tobacco-related diseases and the negative health effects associated with smoking. Identifying and addressing the underlying cause, which is smoking in this case, is crucial to improving health outcomes and reducing the risk of tobacco-related diseases.
To address the cosmetic concerns associated with yellow nails due to smoking, various remedies can be employed. For nails, it is recommended to use specific cleaning products such as apple cider vinegar, hydrogen peroxide, or mouthwash. Soaking the nails in mouthwash or a mixture of hydrogen peroxide and water for about 15-30 minutes, followed by buffing with a toothbrush, can help reduce discolouration. Additionally, rubbing orange peels or lemon juice, which has natural bleaching properties, on the nails can be effective.
In summary, yellow nails are a common consequence of smoking due to the deposition of tar and nicotine on the nails. While this discolouration is not a direct health threat, it serves as a visible indicator of potential tobacco-related health risks. Addressing the underlying cause of smoking is essential, and various remedies can help mitigate the cosmetic concerns associated with yellow nails.

Vitamin deficiencies
Yellowing of the nails can be caused by vitamin or mineral deficiencies. Introducing a multivitamin supplement to your regimen may stop the problem. Vitamin E, in particular, is known to help cells retain moisture and look healthier. It has been clinically studied as a successful treatment for yellow nail syndrome. Since vitamin E stimulates healthy nail growth, it can be applied topically or taken orally to help your nails grow in quickly.
Yellow nail syndrome is a rare disease that affects the fingernails and toenails. It is caused by the buildup of lymph under the nails, making them appear yellow. People with yellow nail syndrome may also develop pulmonary and lymphatic system problems, as well as swelling or lymphedema in the lower limbs. The lymphatic system is part of the immune system, and problems in this system can cause lymph buildup, resulting in swelling under the skin.
Yellow nail syndrome can be treated with oral vitamin E and triazole antifungal medications. Vitamin E helps cells retain moisture and look healthier, and it stimulates healthy nail growth. It is important to note that yellow nails can also be caused by other factors such as fungal infections, smoking, medications, health conditions, and dyes from nail polish and self-tanner.
