The Bottom Line On Fingernails and Life Expectancy

Your fingernails can provide surprising information about your body’s aging process and underlying diseases. As per Dr. Sinclair, tracking your nail development may help reveal how well your body regenerates and ages. Changes in the color, texture, or shape of your nails may also indicate health issues that need medical treatment. While not every nail anomaly is cause for concern, being aware of these warning signs can help you take preventative measures for improved health. If you observe substantial changes in your nail development or look, see a doctor to rule out any underlying health problems.
