Why toenails get thick and turn yellow

Posted on

Toenails can become thick and turn yellow due to various reasons, ranging from fungal infections to underlying health conditions. One common cause is onychomycosis, a fungal infection that affects the toenails. Fungi thrive in warm, moist environments, making the feet, particularly the area around the toes, a prime location for infection. When fungi infect the toenails, they can cause the nails to thicken, become discolored, and develop a yellowish hue.

Another factor contributing to thick, yellow toenails is age. As people get older, their nails tend to grow more slowly and may become thicker and more brittle. Additionally, years of wear and tear on the toenails can lead to damage and discoloration. This is especially true for individuals who engage in activities that put repeated pressure on the toes, such as running or wearing tight-fitting shoes.

Poor hygiene can also play a role in the development of thick, yellow toenails. Failing to keep the feet clean and dry can create an environment where fungi can thrive. Additionally, wearing socks and shoes for extended periods without allowing the feet to breathe can contribute to fungal growth and nail discoloration. Regularly washing and thoroughly drying the feet can help prevent fungal infections and maintain the health of the toenails.

Certain medical conditions can predispose individuals to developing thick, yellow toenails. For example, diabetes can affect blood circulation and immune function, making individuals more susceptible to infections, including fungal nail infections. Peripheral arterial disease (PAD), a condition characterized by narrowed arteries in the legs and feet, can also impair blood flow to the toes, increasing the risk of nail problems.

Psoriasis, a chronic autoimmune disease that causes inflammation and scaling of the skin, can also affect the nails, causing them to thicken, become pitted, and develop a yellowish discoloration. Similarly, eczema, another inflammatory skin condition, can affect the nails and lead to changes in their appearance.

In some cases, thick, yellow toenails may be a sign of a more serious underlying health condition. For example, yellow nail syndrome is a rare disorder characterized by yellowish discoloration, thickening, and slow growth of the nails. It is often associated with respiratory conditions, such as chronic bronchitis or sinusitis, and lymphatic problems.

Certain medications can also cause changes in the nails, including thickening and yellowing. For example, long-term use of antifungal medications, such as terbinafine or fluconazole, can sometimes lead to discoloration of the nails as a side effect. Chemotherapy drugs, which are used to treat cancer, can also affect nail health and cause changes in their appearance.

Treating thick, yellow toenails often requires addressing the underlying cause of the problem. For fungal infections, antifungal medications, either in topical or oral form, are typically prescribed to eliminate the infection and restore the health of the nails. It’s important to follow the prescribed treatment regimen carefully and continue treatment for the recommended duration to ensure that the infection is fully eradicated.

In addition to antifungal medications, there are several home remedies and lifestyle changes that can help improve the appearance of thick, yellow toenails. For example, soaking the feet in warm water with added Epsom salt or apple cider vinegar may help soften the nails and reduce thickening. Trimming the nails regularly and keeping them short can also prevent them from becoming too thick and minimize the risk of further damage.

Maintaining good foot hygiene is crucial for preventing and managing thick, yellow toenails. This includes washing the feet daily with soap and water, drying them thoroughly, and applying moisturizer to keep the skin and nails hydrated. It’s also important to wear clean socks made of breathable materials and to choose shoes that fit properly and provide adequate support and ventilation.

In some cases, thick, yellow toenails may require professional treatment by a podiatrist or dermatologist. For example, if the nails are severely thickened or if there are signs of infection, such as pain, redness, or drainage, a healthcare provider may recommend debridement, which involves thinning the nails to reduce their thickness and alleviate discomfort. In severe cases, surgical removal of the affected nails may be necessary to allow healthy nails to grow in their place.

Overall, thick, yellow toenails can be a frustrating and embarrassing problem, but with proper care and treatment, it is often possible to improve their appearance and restore nail health. By addressing the underlying cause of the problem and adopting good foot hygiene practices, individuals can take steps to prevent and manage thick, yellow toenails effectively.
