Lip biting involves repeatedly biting or chewing on one’s lips. This behavior often occurs due to stress, anxiety, or as a nervous habit. In Lesch-Nyhan syndrome, individuals engage in lip biting as part of their self-injurious behaviors. The behavior can lead to severe damage, sores, and infections on the lips, requiring medical attention to manage complications.
