Which nail condition could indicate a fungal infection?

Discoloration or unusual thickness of the nails is a telling sign that could indicate a fungal infection. In many cases, fungal infections of the nails can alter their appearance, leading to a change in color that can range from yellow to green, brown, or even black. Additionally, the infection may cause the nail to thicken abnormally, which is a common symptom associated with the buildup of keratin and debris under the nail.

These symptoms arise because fungi thrive in warm, moist environments and can disrupt the normal growth and structure of the nail. Consequently, recognizing these signs is crucial for early diagnosis and treatment of a potential fungal infection, preserving nail health and preventing further complications.

In contrast, the other conditions mentioned, such as shedding or ripping of the nail, do not specifically point to a fungal infection and may arise from trauma or other non-fungal-related issues. Clear and shiny nails would typically signify a healthy condition, further emphasizing that discoloration and unusual thickness are indicative of a fungal concern.
