lautophagie

Lautophagia is a relatively rare eating disorder characterized by the compulsive consumption of one's own body tissues, most commonly skin, lips, nails, or hair. The term derives from the Greek words "lauto" meaning self and "phagein" meaning to eat. This condition is classified as a type of self-mutilating behavior and is often associated with underlying psychological distress.

The most common forms of lautophagia include dermatophagia, which involves compulsive skin picking and eating, and onychophagia, commonly known as nail biting. Individuals may consume scabs, cuticles, calluses, or other skin tissues, often leading to physical damage and potential infections. The behavior typically begins in childhood or adolescence and may persist into adulthood.

Lautophagia is frequently linked to anxiety disorders, obsessive-compulsive disorder, depression, and stress-related conditions. Some researchers suggest it may serve as a coping mechanism for emotional distress or provide temporary relief from psychological tension. The act often becomes habitual and difficult to control, even when individuals are aware of the potential health consequences.

Treatment typically involves addressing underlying psychological factors through cognitive-behavioral therapy, habit reversal training, or medication when appropriate. Dermatologists may also be involved to treat physical wounds and prevent infections. Success rates vary depending on the individual's commitment to treatment and the severity of underlying psychological conditions.

The condition is sometimes confused with other body-focused repetitive behaviors like trichotillomania, but lautophagia specifically involves the consumption of body tissues rather than just pulling or picking them. While not as widely studied as other eating disorders, lautophagia represents a significant mental health concern that requires professional intervention to prevent both physical and psychological complications.
