Puffiness under the eyes can be bothersome, but it’s usually just a cosmetic concern. While rare, undereye puffiness can be a symptom of some kidney and thyroid conditions. If you occasionally wake up with puffiness under the eyes, consider what you did the day before to look for lifestyle causes such as staying up late or eating too much salt. Consider talking to your doctor about possible treatments for chronic undereye puffiness.
