What symptom might suggest an underlying issue with the nail plate?

Lifting and discoloration of the nail plate are key indicators that suggest an underlying issue. These symptoms can be indicative of various conditions, such as fungal infections, psoriasis, or other dermatological issues that affect the nail's health. When the nail becomes discolored or starts to lift from the nail bed, it may signal that there is a problem either with the nail itself or the underlying tissue that supports it.

In a healthy nail, one would expect a consistent shape and a normal growth rate, as well as a typical shine. However, when these aspects are disrupted, particularly by changes in color or structural integrity, it often points to a more serious condition that may require further investigation or treatment. In contrast, regular nail shapes, consistent growth rates, and a perfect shine reflect optimal nail health and do not suggest any underlying issues.
