Yellow Toenails
Yellowing nails can have several possible causes. In darker skin tones, thicker nails can develop a yellowish hue naturally with aging. But new yellow discoloration could potentially indicate:
Fungal Infection
The most common cause, especially with nail thickening and crumbling. Fungi thrive in warm, moist areas like toes in shoes and socks. Anti-fungal creams or oral medications may be used for treatment if fungus is confirmed.
Bruising
Injury and bruising can also lead to yellowish or other discolored patches under nails. Protecting toes from impact and allowing bruises time to heal is the best approach.
Psoriasis
An autoimmune condition causing buildup of skin cells. In more pigmented skin, psoriasis presents as yellow rather than white scale patches. Seeking treatment can help manage flare-ups.
Diabetes
Poor circulation and nerve damage from high blood sugar can show up as fungal-looking infections. Seeing a doctor to control diabetes can improve related skin problems.
The first step with any unusual nail changes is scheduling an exam with your doctor or dermatologist, especially if additional symptoms are present. Trying self-treatments without knowing the cause can possibly worsen some conditions.
