What can the appearance of nails indicate?

The appearance of nails is a significant indicator of the general health of the body. Nails can reflect various health conditions, as they are living tissues that can change in response to underlying systemic issues. For instance, changes in nail color, texture, or growth rate can signify nutritional deficiencies, infections, or systemic diseases such as liver or kidney problems.

For example, pale or white nails might indicate liver conditions, while a bluish tint can suggest respiratory or cardiovascular issues. Additionally, ridges or pitting in nails may point to conditions like psoriasis or other dermatological disorders. Thus, observing the condition of the nails can provide valuable insights for health professionals about a person's overall health status.
