What visible signs may appear on nails during a fungal infection?

During a fungal infection, nails often present with white or yellow spots or discoloration, which is a hallmark sign of such an infection. This discoloration occurs because the fungus disrupts the normal structure and health of the nail plate, leading to visible changes. The infection can cause the nail to appear dull, discolored, or even develop a thick, crumbling texture.

Understanding this symptom is crucial for early detection and treatment. While other symptoms like extreme brittleness or texture changes can occur due to various other factors, the characteristic white or yellow discoloration is widely recognized as a clear indicator of a fungal infection. Early identification of these signs can help in seeking proper treatment, preventing further spreading or complications associated with nail fungi.
