The nails are purely aesthetic feature, but they’re more than a platform for bright colors and nail art. The texture, shape and color of the nail are a window into the body as it can reveal a lot about the health. They indicate injury or fungal nail infection or more serious conditions like cancer. The changes in the nails like thickening and discoloration can be a sign of many health issues like kidney and liver diseases, diabetes, lung and heart conditions and anemia.

The nail’s growth rate can also reveal things about the health. Healthy nails grow 3.5mm a month but this can be affected by the aging process, medications, trauma, chronic disease and the nutritional status. If you notice some dramatic changes in the nails like shape changes, thickness, swelling or discoloration, you should consult a dermatologist.
